What about Dinner? Chemical and Microresidue Analysis Reveals the Function of Late Neolithic Ceramic Pans.

The Late Neolithic palafitte site, Ustie na Drim, in the northern part of Lake Ohrid (North Macedonia), excavated in 1962, offered ceramic fragments of large, flat, elongated pans. These artifacts could be dated by relative chronology to roughly around 5200-5000 BC. According to their shape and technological traits, the ceramic pans were probably used for baking. The attached materials on the surface of studied pan fragments were sampled for consequent chemical and microscopical analyses (i.e., analyses of starch, phytoliths, and microscopic animal remains). An immunological method revealed the presence of pork proteins in samples. The presence of organic residues of animal origin was, moreover, confirmed by the detection of cholesterol using gas chromatography coupled to mass spectrometry. Analysis of detected microscopic botanical objects revealed starch grains of several plants (i.e., oak, cattail, and grasses). An interesting find was the hair of a beetle larva, which could be interpreted contextually as the khapra beetle, a pest of grain and flour. Based on our data, we suppose that the ceramic pans from Ustie na Drim were used for the preparation of meals containing meat from common livestock in combination with cereals and wild plants.

The prehistoric roots of Chinese cuisines: Mapping staple food systems of China, 6000 BC-220 AD.

We conducted a meta-analysis of published carbon and nitrogen isotope data from archaeological human skeletal remains (n = 2448) from 128 sites cross China in order to investigate broad spatial and temporal patterns in the formation of staple cuisines. Between 6000-5000 cal BC we found evidence for an already distinct north versus south divide in the use of main crop staples (namely millet vs. a broad spectrum of C3 plant based diet including rice) that became more pronounced between 5000-2000 cal BC. We infer that this pattern can be understood as a difference in the spectrum of subsistence activities employed in the Loess Plateau and the Yangtze-Huai regions, which can be partly explained by differences in environmental conditions. We argue that regional differentiation in dietary tradition are not driven by differences in the conventional "stages" of shifting modes of subsistence (hunting-foraging-pastoralism-farming), but rather by myriad subsistence choices that combined and discarded modes in a number of innovative ways over thousands of years. The introduction of wheat and barley from southwestern Asia after 2000 cal BC resulted in the development of an additional east to west gradient in the degree of incorporation of the different staple products into human diets. Wheat and barley were rapidly adopted as staple foods in the Continental Interior contra the very gradual pace of adoption of these western crops in the Loess Plateau. While environmental and social factors likely contributed to their slow adoption, we explored local cooking practice as a third explanation; wheat and barley may have been more readily folded into grinding-and-baking cooking traditions than into steaming-and-boiling traditions. Changes in these culinary practices may have begun in the female sector of society.

Mechanisms of lipid preservation in archaeological clay ceramics revealed by mass spectrometry imaging.

Traces of lipids, absorbed and preserved for millennia within the inorganic matrix of ceramic vessels, act as molecular fossils and provide manifold information about past people's subsistence, diet, and rituals. It is widely assumed that lipids become preserved after adsorption into nano- to micrometer-sized pores, but to this day the distribution of these lipids in the ceramics was virtually unknown, which severely limits our understanding about the process of lipid preservation. Here we use secondary ion mass spectrometry (SIMS) imaging for direct in situ analysis of lipids absorbed in 700- to 2,000-y-old archaeological pottery. After sectioning from larger sherds, wall cross-sections of smaller fragments were used for SIMS analysis. Lipids were found in relatively large zones of 5- to 400-µm diameter, which does not support the notion of absorption only into individual nanometer-scale pores but indicates that more macroscopic structures in the ceramics are involved in lipid preservation as well. Furthermore, lipids were found concentrated on calcium carbonate inclusions in the ceramics, which suggests that precipitation of fatty acids as calcium salts is an important aspect of lipid preservation in archaeological samples. This has important implications for analytical methods based on extraction of lipids from archaeological ceramics and needs to be considered to maximize the yield and available information from each unique sample.

Interpretation of bulk nitrogen and carbon isotopes in archaeological foodcrusts on potsherds.

RATIONALE: Foodcrust, the charred deposit adhering to the surface of containers, is a possible source of information on the function of ancient vessels and the subsistence of prehistoric humans. While the carbon isotope ratios in those materials are useful in detecting the usage of C4 plants, the reliability of nitrogen isotopic signatures has not been fully investigated. METHODS: The validity of bulk nitrogen isotope ratios has previously been investigated in coastal or riverine environments, where multiple resources from terrestrial and aquatic ecosystems were available, but not in terrestrial settings which provide a simpler mixing of terrestrial animals and plants. Hence, we conducted an exhaustive study on charred deposits on potsherds at two inland archaeological sites belonging to prehistoric Jomon hunter-gathers in central Japan, focusing on δ15 N values and atomic N/C ratios determined using an isotope ratio mass spectrometer and an elemental analyzer, respectively. RESULTS: For both sites, the δ15 N values showed significant correlations with the N/C ratios among samples from the inner surface, suggesting that these have recorded animal contribution. Furthermore, previous studies of Neolithic pottery from North Europe and Far East Russia bearing strong marine signatures had shown reasonably higher δ15 N values and N/C ratios in comparison with our data from terrestrial settings. On the other hand, some charred materials probably originating from plant starch showed lower values with both parameters. Samples from the outer surface produced less meaningful isotopic and elemental ratios altered by a thermal effect and/or contamination from soot. CONCLUSIONS: When the samples of foodcrusts were selected carefully from the inner surface, bulk nitrogen isotopes and N/C ratios reflect the composition of what was cooked or processed in containers. This will provide useful information for understanding the human adaptation from the Late Pleistocene to the Holocene in conjunction with residual lipid analyses.

From Neandertals to modern humans: New data on the Uluzzian.

Having thrived in Eurasia for 350,000 years Neandertals disappeared from the record around 40,000-37,000 years ago, after modern humans entered Europe. It was a complex process of population interactions that included cultural exchanges and admixture between Neandertals and dispersing groups of modern humans. In Europe Neandertals are always associated with the Mousterian while the Aurignacian is associated with modern humans only. The onset of the Aurignacian is preceded by "transitional" industries which show some similarities with the Mousterian but also contain modern tool forms. Information on these industries is often incomplete or disputed and this is true of the Uluzzian. We present the results of taphonomic, typological and technological analyses of two Uluzzian sites, Grotta La Fabbrica (Tuscany) and the newly discovered site of Colle Rotondo (Latium). Comparisons with Castelcivita and Grotta del Cavallo show that the Uluzzian is a coherent cultural unit lasting about five millennia, replaced by the Protoaurignacian before the eruption of the Campanian Ignimbrite. The lack of skeletal remains at our two sites and the controversy surrounding the stratigraphic position of modern human teeth at Cavallo makes it difficult to reach agreement about authorship of the Uluzzian, for which alternative hypotheses have been proposed. Pending the discovery of DNA or further human remains, these hypotheses can only be evaluated by archaeological arguments, i.e. evidence of continuities and discontinuities between the Uluzzian and the preceding and succeeding culture units in Italy. However, in the context of "transitional" industries with disputed dates for the arrival of modern humans in Europe, and considering the case of the Châtelperronian, an Upper Paleolithic industry made by Neandertals, typo-technology used as an indicator of hominin authorship has limited predictive value. We corroborate previous suggestions that the Middle-to-Upper Paleolithic transition occurred as steps of rapid changes and geographically uneven rates of spread.

Dental wear quantity and direction in Chalcolithic and Medieval populations from southwest France.

The aim of this study was to verify if dental wear changed due to the dietary shift between the Chalcolithic and Middle Ages from relatively hard and fibrous foods to soft cooked cereals. This was accomplished by comparing dental wear quantity and direction between people from two archaeological sites, Les Treilles during the Chalcolithic (mixed subsistence farmers) and Marsan from the Middle Ages (agriculturalists) in southwest France. The materials studied include 65 mandibles, 32 from Les Treilles and 33 from Marsan; 549 teeth were studied. The results show statistically significant difference in wear quantity and direction, the Chalcolithic population (Les Treilles) had the greatest levels of wear in a mainly oblique direction, with the anterior teeth heavily affected by wear. Comparatively, the Medieval sample (Marsan) had lesser levels of wear in a mainly horizontal direction, and the most heavily worn teeth were the molars and incisors. The quantity of wear seems to correlate well with changes in diet, the high level of wear on the anterior teeth in the Chalcolithic sample corresponds with the consumption of a mixed diet of fibrous and tough foods. At Marsan, the lower wear quantity was likely due to a diet of soft boiled cereals, requiring less mastication. However, wear direction appears dependent on several factors and may correlate with more mixed subsistence practices. This study demonstrates the need for additional research into the complex actions of mastication and its effect on dental wear, as well as standardised methodology for the examination of dental wear in archaeological samples.

[Comparative analysis between origin of cooked traditional Chinese medicine powder and modern formula granules].

In this study, the origin and causes of cooked traditional Chinese medicine powder were reviewed, and a comprehensive analysis was made for the time background of modern traditional Chinese medicine formula granules and the future development trend, in order to provide reference for application and promotion of traditional Chinese medicine formula granules. By reference to ancient medical books of previous dynasties, a system review was conducted for infancy, formation, maturity and transition of cooked traditional Chinese medicine powder, and a comprehensive analysis was made for the six factors of cooked traditional Chinese medicine powder's maturity in the Song Dynasty. Efforts were made to collect domestic and foreign research literatures of modern formula granules, understand the detailed development, and conduct an objective analysis of the current clinical application of modern formula granules. According to the comparative analysis for the application characteristics of cooked traditional Chinese medicine powder and modern formula granules, ①the popularity of cooked traditional Chinese medicine powder in the Song Dynasty has six factors: soaring numbers of medical students and medical practitioners, high medical expenses due to huge army, rapid population growth, frequent epidemics and increasing diseases, and insufficient finances of central and local governments. ②On the basis of clinical application characteristics of traditional Chinese medicine formula granules, traditional Chinese medicine formula granules contain extracted and concentrated effective components, which guarantee the curative effect, meet modern people's demands for "quick, simple and convenience" traditional Chinese medicine decoctions, show a relatively high cost performance; however, formula granules are restricted by their varieties and lack unified quality control standards, and single-extract formula granules have not synergy and attenuation effects of combined traditional Chinese medicine decoctions, which also restricts its clinical application and promotion. ③Both have advantages in the process of clinical application, and shall be used based on syndromes. In conclusion, traditional Chinese medicine formula granules do not have disadvantages of "difficult, complicated, turbid and disorderly" cooked traditional Chinese medicine powder, and solve such problems as "inflexibility, expensiveness, restriction, disorder and inefficacy", which is the important basis for promoting traditional Chinese medicine formula granules.

Fire in the Plio-Pleistocene: the functions of hominin fire use, and the mechanistic, developmental and evolutionary consequences.

Fire is a powerful natural force that can change landscapes extremely quickly. Hominins have harnessed this resource for their own purposes, with mechanistic and developmental physiological consequences. In addition, the use of fire has niche constructive effects, altering selective environments for genetic and cultural evolution. We review the record for hominin fire use in the Plio-Pleistocene, before considering the various functions for its use, and the resultant mechanistic and developmental consequences. We also adopt the niche construction framework to consider how the use of fire can modify selective environments, and thus have evolutionary consequences at genetic and cultural levels. The light that fire produces may influence photoperiodicity and alter hormonally-controlled bodily rhythms. Fire used for cooking could have extended the range of foods hominins were able to consume, and reduced digestion costs. This may have contributed to the expansion of the hominin brain and facial anatomy, influenced by a higher quality cooked diet. Fire may also have allowed dispersal into northern areas with much cooler climates than the hominin African origin, posing novel problems that affected diet and social behaviour.

Health, wellness and the allure of spices in the Middle Ages.

ETHNOPHARMOCOLOGICAL RELEVANCE: During the European Middle Ages aromatic products imported from Asia and Africa were credited with both preventive and curative medical properties. In addition spices provided an image of wellness and as they were expensive and had many uses in cuisine and fragrance, they functioned as prestige consumer goods. MATERIALS AND METHODS: This is an effort to look historically at a social and cultural phenomenon for the period roughly A.D. 1200-1500. Sources of information about the demand for and uses of spices include lists of materia medica, medical treatises, cookbooks, religious writings, descriptions of banquets and court ceremonial and literary works showing what might be called aspirational lifestyles. RESULTS: It is important to focus on the demand side of the spice trade rather than simply assuming a consistent demand and looking only at the supply (prices, routes, for example). CONCLUSIONS: The demand for spices must be understood in terms of their attributed medical and wellness powers, but these in turn are related to the mysterious Eastern origins of spices that enhanced their image as elite consumer products and their association with spiritual as well as medical healing.

The Roman and Islamic spice trade: New archaeological evidence.

ETHNOPHARMACOLOGICAL RELEVANCE: Tropical spices have long been utilized in traditional medicine and cuisine. New archaeological evidence highlights temporal changes in the nature and scale of the ancient spice trade and in the ancient usage of these plants. Furthermore, a study of their 'materiality' highlights that the impact of spices extends beyond their material properties. Here the botanical remains of spices recovered from archaeological excavations at a port active in the Roman and medieval Islamic spice trade are evaluated. MATERIALS AND METHODS: Recent excavations at Quseir al-Qadim, an ancient port located on the Red Sea coast of Egypt, have provided new evidence for the spice trade. Due to the arid conditions ancient botanical remains were preserved in abundance and these included spices, as well as a wide range of other food plants. Quseir al-Qadim was active as a transport hub during both the Roman and Islamic periods (ca. AD 1-250, known as Myos Hormos, and again during ca. AD 1050-1500, known as Kusayr), and the remains thus facilitate a study of temporal change in the trade and usage of these spices. Standard archaeobotanical methods were used to recover, identify and analyze these remains. RESULTS: At least seven tropical spices were recovered from the excavations, as well as several other tropical imports, including black pepper (Piper nigrum), ginger (Zingiber officinale), cardamom (Elettaria cardamomum), turmeric (Curcuma sp.), fagara (cf. Tetradium ruticarpum), myrobalan (Terminalia bellirica and Terminalia chebula) and betelnut (Areca catechu). A marked contrast between the two chronological periods in the range of spices recovered points to changes in the nature and scale of the trade between the Roman and medieval Islamic periods, while differences in the contexts from which they were recovered help to identify temporal changes in the way in which the spices were utilized during those periods. CONCLUSION: Archaeological and textual evidence suggest that in antiquity spices were used in ritual (funeral rites, offerings), in perfumery, and in medicinal remedies, with black pepper the only tropical spice regularly employed in cuisine. By the medieval period the culinary role of spices had grown significantly, both in the Middle East and in Europe, while retaining their importance in medicinal applications. In both time periods they were luxuries available only to the upper strata of society, but the material properties of spices and their elite status made them desirable to a wider section of society. In their pursuit of spices people became entangled in a meshwork of relationships, altered social realities and political power struggles. Globalization is one such entanglement, highlighting that the potency of spices goes far beyond their ability to stimulate our taste buds, delight our sense of smell and cure our ailments.

Prehispanic use of chili peppers in Chiapas, Mexico.

The genus Capsicum is New World in origin and represents a complex of a wide variety of both wild and domesticated taxa. Peppers or fruits of Capsicum species rarely have been identified in the paleoethnobotanical record in either Meso- or South America. We report here confirmation of Capsicum sp. residues from pottery samples excavated at Chiapa de Corzo in southern Mexico dated from Middle to Late Preclassic periods (400 BCE to 300 CE). Residues from 13 different pottery types were collected and extracted using standard techniques. Presence of Capsicum was confirmed by ultra-performance liquid chromatography (UPLC)/MS-MS Analysis. Five pottery types exhibited chemical peaks for Capsicum when compared to the standard (dihydrocapsaicin). No peaks were observed in the remaining eight samples. Results of the chemical extractions provide conclusive evidence for Capsicum use at Chiapas de Corzo during a 700 year period (400 BCE-300 CE). Presence of Capsicum in different types of culinary-associated pottery raises questions how chili pepper could have been used during this early time period. As Pre-Columbian cacao products sometimes were flavored using Capsicum, the same pottery sample set was tested for evidence of cacao using a theobromine marker: these results were negative. As each vessel that tested positive for Capsicum had a culinary use we suggest here the possibility that chili residues from the Chiapas de Corzo pottery samples reflect either paste or beverage preparations for religious, festival, or every day culinary use. Alternatively, some vessels that tested positive merely could have been used to store peppers. Most interesting from an archaeological context was the presence of Capsicum residue obtained from a spouted jar, a pottery type previously thought only to be used for pouring liquids.

Earliest evidence for the use of pottery.

Pottery was a hunter-gatherer innovation that first emerged in East Asia between 20,000 and 12,000 calibrated years before present (cal bp), towards the end of the Late Pleistocene epoch, a period of time when humans were adjusting to changing climates and new environments. Ceramic container technologies were one of a range of late glacial adaptations that were pivotal to structuring subsequent cultural trajectories in different regions of the world, but the reasons for their emergence and widespread uptake are poorly understood. The first ceramic containers must have provided prehistoric hunter-gatherers with attractive new strategies for processing and consuming foodstuffs, but virtually nothing is known of how early pots were used. Here we report the chemical analysis of food residues associated with Late Pleistocene pottery, focusing on one of the best-studied prehistoric ceramic sequences in the world, the Japanese Jomon. We demonstrate that lipids can be recovered reliably from charred surface deposits adhering to pottery dating from about 15,000 to 11,800 cal bp (the Incipient Jomon period), the oldest pottery so far investigated, and that in most cases these organic compounds are unequivocally derived from processing freshwater and marine organisms. Stable isotope data support the lipid evidence and suggest that most of the 101 charred deposits analysed, from across the major islands of Japan, were derived from high-trophic-level aquatic food. Productive aquatic ecotones were heavily exploited by late glacial foragers, perhaps providing an initial impetus for investment in ceramic container technology, and paving the way for further intensification of pottery use by hunter-gatherers in the early Holocene epoch. Now that we have shown that it is possible to analyse organic residues from some of the world's earliest ceramic vessels, the subsequent development of this critical technology can be clarified through further widespread testing of hunter-gatherer pottery from later periods.

Bites, nibbles, sips and puffs: new exotic goods in Norway in the 18th and the first half of the 19th century.

The slow but significant changes in the material culture of European households that took place in the pre-industrial period are visible in several ways, such as in the changing patterns of housing, furnishing and clothing which have been illustrated in several studies. However, most of these studies focus on the pre-industrial economic leaders, often ignoring the changes taking place on the margins of the economic growth centres. This article seeks to rectify this by looking at changes in the material culture in one such 'marginal' country, namely Norway. The goods focused upon in this case are sugar, tobacco and coffee, which are often termed as exotic goods. These were new commodities in the 18th century and precisely because of their novelty and foreign origin, it is in many cases possible to trace how they spread in rural society, as well as how they impacted it. The emphasis has been put on rural areas for the simple reason that this was where the overall majority of Norwegians lived at the time.

Murdered bread, living bread: Doris Grant and the homemade, wholemeal loaf.

Doris Grant (1905-2003), a middle-class, British housewife, published numerous books from the 1940s into the 1970s urging her fellow housewives to bake organic, wholemeal bread for their families. This article argues that Grant's arguments defy easy categorization as either 'conservative' or 'progressive'. On the one hand, her targeted appeal to women reflected a traditional, conservative understanding of gender roles: women were, first and foremost, wives and mothers and therefore naturally responsible for family diet and health. On the other hand, Grant also pushed her readers to look beyond their homes and recognize a dangerous food supply system that was impinging on their daily lives. She demanded that her readers reject comfortable complicity in this system and preached the value of individual action in effecting substantive change.

A journey into the imaginary of Sicilian pastry.

This article is an anthropological archeology of Sicilian confectionery, from the prehistoric-like assemblage of sesame seeds and honey (giurgiulena) to the extravagant gelato di campagna and the baroque-rustic cassata. Sweets are analyzed as architectural constructions that rely on newly discovered ingredients and techniques to create edible edifices that amazed the eye as much as the palate. They emerge from their historical and social context and affirm themselves as moments of innovation in the culinary art. On a deeper level, the art of pasticceri bears the marks of an existential quest that constantly redefines man's symbolic relation to the forces and contrasts of life.

[Talking about the scene of diet and cooking based on Pao Chu Tu (kitchen picture) of Han dynasty].

The Pao Chu Tu (kitchen picture) of Han dynasty stone relief reconstructed the state of dietary cooking of Han dynasty with vivid and authentic picture. The Pao Chu Tu (kitchen picture) of Shandong Zhucheng city depicted ancient enormous and busy cooking scene which involved all kinds of cooking activities such as butcher, bailing, stewing, roast and brewing wine etc, displaying the advanced kitchen ware e.g. kettle, caldron, tripod, oven and complex cooking technology of Han Chinese people such as steaming, boiling, stirring baking and roast etc, reflecting rich dietary categories of Han dynasty. The Pao Chu Tu (kitchen picture) of Han dynasty stone relief provide us precious datas for the purpose of the study of dietary living of Han dynasty.

Study of the organic residue from a 2600-year old Etruscan plumpekanne.

Excavation of the Etruscan Necropolis dell'Osteria near Vulci (VI Century b.c.) brought to light in Tomb 2 a bronze plumpekanne. According to preliminary X-ray observation, an unusually thick deposit of organic nature lay at its bottom. Numerous samples of the residue were investigated using microFTIR and diffuse reflectance FTIR spectroscopy. For comparative purposes similar analyses were performed on samples of resins mentioned in classical sources. Spectroscopic results identify the residue as mastic or incense, both triterpenic resins. The former seems to be preferred since, according to classical sources, it was used as must additive.

Culinary archaeology: Millet noodles in Late Neolithic China.

Noodles have been a popular staple food in many parts of the world for at least 2,000 years, although it is debatable whether the Chinese, the Italians or the Arabs invented them first. Here we analyse a prehistoric sample of noodles contained in a well preserved, sealed earthenware bowl discovered in the Late Neolithic archaeological site of Lajia in northwestern China. We identify millet as the source of the abundant seed-husk phytoliths and starch grains present in the vessel. This shows that the conversion of ground millet flour into dough that could be repeatedly stretched into long, thin strands for the preparation of boiled noodles was already established in this region 4,000 years ago.
