RESUMO
Fermentable oligo-, di- and monosaccharides and polyols (FODMAP) comprise several previously unrelated carbohydrates, such as fructans, fructo-oligosaccharides, galacto-oligosaccharides, fructose (in excess of glucose), mannitol and sorbitol, and among others. For many patients with gastro-intestinal disorders, such as irritable bowel syndrome, the ingestion of FODMAP triggers symptoms and causes discomfort. Among the main contributors to the dietary FODMAP intake are baking products, in particular bread as a major global staple food. This is primarily due to the fructan content of the cereal flours, but also process induced accumulation of FODMAP is possible. To provide low-FODMAP baking products, researchers have investigated various approaches, such as bio-process reduction by yeast, lactic acid bacteria, germination of the raw material or the use of exogenous enzymes. In addition, the selection of appropriate ingredients, which are either naturally or after pretreatment suitable for low-FODMAP products, is discussed. The sensory and nutritional quality of low-FODMAP baking products is another issue, that is addressed, with particular focus on providing sufficient dietary fiber intake. Based on this information, the current state of low-FODMAP baking and future research necessities, to establish practical strategies for low-FODMAP products, are evaluated in this article.
RESUMO
Taking into account that many advantages have been associated with the consumption of spirulina (microalgae) in terms of antioxidant capacity, anticancer, anti-inflammatory, and anti-aging activities, the study focuses on spirulina supplementation of semolina-based pasta. Fresh pasta was prepared by mixing semolina flour (Triticum durum) with an addition of 3, 5, 7, and 10% (w/w) of spirulina (Arthrospira platensis) powder. Physicochemical and nutritional analyses were done on raw materials, and on fresh pasta before and after cooking. Sensorial analysis was done shortly after cooking pastas. Spirulina had a high content of protein (71.34%), with all the essential amino acids, a high total fiber (8.45%), as well as ash content (5.93%), which significantly increased the nutritional value of the obtained fresh pasta. Supplemented pastas have a significantly better amino acid profile and higher total fiber content (up to 2.99 g/100 g d.m.) than the control sample. Moreover, the addition of spirulina had a significant effect on the pasta's color, weight gain, and cooking loss after being cooked. The addition of spirulina also affected the scores obtained for the individual parameters (texture, color, flavor, taste, and overall acceptability) of the sensory evaluation.

Wheat bread, produced by the single-phase method, is a common food consumed all over the world. Due to changes in lifestyle and nutritional trends, alternative raw materials are sought to increase the nutritional value and improve the taste of daily consumed products. Additionally, customers seek a wide variety of foods, especially when it comes to basic foods. Nuts, such as coconuts or chestnuts, might provide an attractive flavour with benefits to the nutritional quality. In this study, the effect of substituting wheat flour with coconut or chestnut flour (flour contribution level: 5, 10, 15, 30, 50% w/w), was evaluated in terms of the breads specific volume, texture, colour, nutritional composition, and dietary fibre fraction contents. Moreover, a sensory evaluation was conducted to assess potential consumer acceptance. Based on the consumer's perception, the overall acceptance of bread with 15% w/w of coconut and chestnut flour was in privilege compared to the control sample. As a result, taking all of the tested parameters into account, the breads with 5, 10, and 15% supplementation of chestnut or coconut flour were still of good quality compared to the wheat bread and their fibre content was significantly higher.

This study examined the thermo-oxidative degradation of stigmasterol fatty acids esters. Stigmasterol stearate, oleate, linoleate and linolenate were synthesized by chemical esterification and their purity evaluated by 1H-NMR and GC-MS. The degradation of stigmasterol esters was examined after heating them at 60 and 180 °C for 1, 2, 4, 8 and 12 h. It was established that stigmasterol esters were prone to thermo-oxidative degradation, with time and temperature affecting the degree of degradation. The unsaturation of fatty acids affected the rate of stigmasteryl ester degradation. The kinetics of StS and StO degradation were similar and the additional double bonds in StL and StLn resulted in their faster decomposition. The esters degraded faster at 180 than at 60 °C. The sterol and fatty acid molecules degraded at different rates, such that the fatty acid moiety deteriorated faster than the sterol at both temperatures, independent of the time of heating and the level of unsaturation.
RESUMO
BACKGROUND: The by-products of seven different cereal grains were investigated as a source of extractable oil, rich in lipophilic bioactive compounds. RESULTS: Oil yields (g kg(-1) DW) recovered from cereal by-products were as follows: 189 (rice bran) > 112 (wheat germ) > 74 (corn bran) > 58 (oat bran) > 41 (buckwheat bran) > 39 (spelt bran) > 33 (wheat bran) > 27 (rye bran). The main fatty acids identified in the studied oil samples were palmitic acid (11.39-17.23%), oleic acid (11.76-42.73%), linoleic acid (35.54-62.65%) and α-linolenic acid (1.05-9.46%). The range of total tocochromanols and phytosterols in the obtained oils was 0.369-3.763 and 1.19-35.24 g kg(-1) of oil, respectively. The oils recovered from buckwheat and corn bran, and wheat germ were dominated by tocopherols (99.9, 84.2 and 96.5%, respectively), whereas the oat, rice, rye, spelt, wheat bran oils were rich in tocotrienols (73.9, 79.6, 78.1, 90.6 and 73.8%, respectively). The campesterol and ß-sitosterol constituted 10.1-32.5 and 30.4-63.7%, respectively, of total phytosterols contents identified in all of the studied samples. CONCLUSION: The present study demonstrated that oils recovered from the cereal by-products are richer sources of bioactive compounds, compared with traditional oils. © 2015 Society of Chemical Industry.

Lipophilic bioactive compounds in oils recovered from the kernels of seven sweet cherry (Prunus avium L.) cultivars, harvested at single location in 2013, were studied. Oil yield in sweet cherry ranged between 30.3-40.3 % (w/w) dw. The main fatty acids were oleic acid (39.62-49.92 %), linoleic acid (31.13-38.81 %), α-eleostearic acid (7.23-10.73 %) and palmitic acid (5.59-7.10 %), all four represented approximately 95 % of the total detected fatty acids. The ranges of total tocochromanols and sterols were between 83.1-111.1 and 233.6-419.4 mg/100 g of oil, respectively. Regardless of the cultivar, the γ-tocopherol and ß-sitosterol were the main lipophilic minor bioactive compounds. The content of the carotenoids and squalene were between 0.38-0.62 and 60.9-127.7 mg/100 g of oil, respectively. Three significant correlations were found between oil yield and total contents of sterols (r = -0.852), tocochromanols (r = -0.880) and carotenoids (r = -0.698) in sweet cherry kernel oils. The oil yield, as well as the content of lipophilic bioactive compounds in oil was significantly affected by the cultivar.

Nutrigenomics attempts to characterize and integrate the relation between dietary molecules and gene expression on a genome-wide level. One of the biologically active nutritional compounds is vitamin D3, which activates via its metabolite 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3) the nuclear receptor VDR (vitamin D receptor). Vitamin D3 can be synthesized endogenously in our skin, but since we spend long times indoors and often live at higher latitudes where for many winter months UV-B radiation is too low, it became a true vitamin. The ligand-inducible transcription factor VDR is expressed in the majority of human tissues and cell types, where it modulates the epigenome at thousands of genomic sites. In a tissue-specific fashion this results in the up- and downregulation of primary vitamin D target genes, some of which are involved in attenuating oxidative stress. Vitamin D affects a wide range of physiological functions including the control of metabolism, bone formation and immunity. In this review, we will discuss how the epigenome- and transcriptome-wide effects of 1,25(OH)2D3 and its receptor VDR serve as a master example in nutrigenomics. In this context, we will outline the basis of a mechanistic understanding for personalized nutrition with vitamin D3.

Bakery products, including bread, are important components of the diet of people all over the world. One of the food industry's goals is to improve its quality in the context of healthiness and physical parameters. Consumers' perception of sensory quality is an important aspect of food choice. Thus, the study aimed to enhance nutritional parameters (antioxidant capacity, content of phenolic compounds) together with maintaining or increasing bread quality (texture, color, volume and sensory properties). Among vegetable juices, tomato, beetroot and carrot were selected, as they are easily accessible in Europe and are inexpensive. At the same time, those juices are known to be high in antioxidants. In this study, the effect of substituting recipe water with tomato, beetroot and carrot juices (replacement level: 15, 30, 50% v/v) was evaluated in terms of the specific volume, texture, color, acidity, polyphenol contents, antioxidant and sensory properties. It was concluded that juice content had a significant positive impact on physicochemical parameters such as volume, color, acidity, as well as the antioxidant activity of breads. The carrot and beetroot juices were the most efficient in terms of shaping wheat bread properties, especially in terms of antioxidant activity.
RESUMO
One of the commonly used food preparation methods is frying. Fried food is admired by consumers due to its unique taste and texture. Deep frying is a process of dipping food in oil at high temperature, usually 170-190 °C, and it requires a relatively short time. The aim of this study was to analyze the thermo-oxidative changes occurring during the deep frying of products such as potatoes and tofu in cold pressed rapeseed oils and palm olein. Cold pressed rapeseed oil from hulled seeds (RO), cold pressed high oleic rapeseed oil from hulled seeds (HORO), and palm olein (PO) (for purposes of comparison) were used. Characterization of fresh oils (after purchase) and oils after 6, 12, and 18 h of deep frying process of a starch product (potatoes) and a protein product (tofu) was performed. The quality of oils was analyzed by determining peroxide value, acid value, p-anisidine value, content of carotenoid and chlorophyll pigments, polar compounds, smoke point, color (CIE L*a*b*), fatty acids content and profile, calculation of lipid nutritional quality indicators, and oxidative stability index (Rancimat). Cold pressed high oleic rapeseed oil was more stable during deep frying compared to cold pressed rapeseed oil, but much less stable than palm olein. In addition, more thermo-oxidative changes occurred in the tested oils when deep frying the starch product (potatoes) compared to the deep frying of the protein product (tofu).

Additionally, fatty acid profiles and thei. RESULTS: nd. Cold-pressed berry seed oils are used for consumption and other applications including skin and hair care. They are natural products which gain the attention of customers. In this study, strawberry, raspberry and blackberry seed oils used for cosmetic purposes, purchased from three different European producers, were analyzed. The aim of the study was to assess the quality and oxidative stability of the berry fruit oils, thus they were analyzed after purchase and after 4 and 8 weeks of storage at room temperature. Materials and methods. Acid and peroxide values were determined in the tested oils, as was oxidative stability, which was measured using pressure differential scanning calorimetry (PDSC). Additionally, fatty acid profiles and their distribution at sn-1,3 and sn-2 positions of triacylglycerols were characterized. Results, principal. Most of the fatty acids of the tested berry seed oils are polyunsaturated fatty acids (67.04-74.95%). The results show the low quality of the tested oils in terms of oxidative stability (high peroxide values: 21.9-249.6 mEq O2/kg oil). CONCLUSIONS: Based on this study, it is necessary to evaluate the effects of these products on the body. Moreover, standards clarifying the oxidation of cosmetic oils should be set internationally.

RESUMO
In accordance with Article 6 of Regulation (EC) No 396/2005, the FPS Health, Food chain safety and Environment of Belgium, submitted an application to modify the existing maximum residue level (MRL) for the active substance cyprodinil in Florence fennel to accommodate the intended use in the northern Europe. The submitted data were found sufficient to derive an MRL proposal of 4 mg/kg for cyprodinil in Florence fennel. Adequate analytical methods for enforcement are available to control the residues of cyprodinil in the plant matrix under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the long-term intake of residues resulting from the authorised uses of cyprodinil and the intended use on Florence fennel is unlikely to present a risk to consumer health. An indicative acute exposure assessment was performed, considering the acute reference dose (ARfD) proposed by the rapporteur Member State (RMS) in the framework of the currently ongoing renewal of the approval of cyprodinil; no acute health concerns were identified with regard to cyprodinil residues in Florence fennel. As the peer review on the renewal of the approval of cyprodinil in accordance with Regulation (EC) No 1107/2009 is currently ongoing, the conclusions reported in this reasoned opinion may need to be reconsidered in the light of the outcome of the peer review.

Adequate analytical methods for enforcement are available to control the residues of pyridaben in plant matrices at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concludes that the proposed use of pyridaben on tomatoes and aubergines will not result in a consumer exposure exceeding the toxicological reference values and therefore it is unlikely to pose a risk to consumers' health.
RESUMO
According to Regulation (EC) No 396/2005 on maximum residue levels of pesticides in or on food and feed, Member States have to monitor pesticide residue levels in food samples and submit the monitoring results to EFSA and the European Commission. The Standard Sample Description (SSD, version 1) is the data model used for reporting the data on analytical measurements of chemical substances occurring in food, feed and water to EFSA. This document is a consolidated version of the past four years' guidance defining the appropriate SSD codes to describe the samples and the analytical results and it gives directions for the reporting of the pesticide residues monitoring data starting with the data generated in 2018 onwards. These provisions take into account the experience of both the previous reporting seasons and the new legislation applicable in 2018. This EFSA Guidance will not be applicable for the 2019 data collection provided to EFSA in 2020. In 2020, all data on annual monitoring will be transmitted in SSD2 format only.
RESUMO
In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Dow AgroSciences submitted a request to the competent national authority in Greece to set an import tolerance for the active substance 2,4-D in genetically modified (GM) soyabeans imported from Canada and the USA. The genetic modification confers tolerance to the herbicide 2,4-D. The data submitted in support of the request provided sufficient evidence to conclude that residues of parent 2,4-D and of the metabolite 2,4-dichlorophenol (2,4-DCP), which was found in the GM soybeans treated with 2,4-D, are unlikely to present a risk for consumers. Sufficiently validated analytical methods are available to enforce the proposed maximum residue level (MRL) in soybeans.
RESUMO
The applicant BASF SE submitted a request to the competent national authority in Germany to evaluate the confirmatory data that were identified for dimethenamid-P in the framework of the maximum residue level (MRL) review under Article 12 of Regulation (EC) No 396/2005 as not available. The data gap refers to the submission of a plant metabolism study investigating the fate of dimethenamid-P following foliar treatment with a short preharvest interval (PHI) in a leafy or bulb vegetable crop. The confirmatory data requirement is considered sufficiently addressed according to the conclusions of the peer review, which, based on available metabolism studies, proposed to modify the existing enforcement and risk assessment residue definitions in all plant commodities, by including additional dimethenamid-P metabolites ((2RS)-3-(2-{(2,4-dimethylthiophen-3-yl)[(2S)-1-methoxypropan-2-yl]amino}-2-oxoethanesulfinyl)-2-hydroxypropanoic acid (M30) and (2RS)-3-[(2-{(2,4-dimethylthiophen-3-yl)[(2S)-1-methoxypropan-2-yl]amino}-2-oxoethyl)sulfanyl]-2-hydroxypropanoic acid (M26). The residue data of metabolites M26 and M30 are currently not available for all authorised uses assessed in the MRL review. Should risk managers decide amending residue definitions, the existing EU MRLs would need to be revised accordingly. The consumer exposure as calculated by the MRL review was updated in two scenarios, using the existing and the new toxicological reference values as derived by the peer review. For the crops under consideration (spring onions, lettuce, escarole and herbs), indicative conversion factors were applied to account for possible metabolite burden. No consumer intake concerns were identified.
RESUMO

The data submitted in support of the request were found to be sufficient to derive an MRL proposal of 1.5 mg/kg for Florence fennels. Adequate analytical methods for enforcement are available to control the residues of fludioxonil on the commodity under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the long-term intake of residues resulting from the use of fludioxonil according to the reported agricultural practice is unlikely to present a risk to consumer health.
RESUMO
In accordance with Article 6 of Regulation (EC) No 396/2005, the applicants Luxembourg Industries (Pamol) Ltd and De Sangosse SAS submitted a request to the competent national authority in France to modify the existing maximum residue level (MRL) for fosetyl/phosphonic acid related to the use of potassium phosphonates on potatoes, wheat and some animal commodities. The data submitted in support of the request were found to be sufficient to derive MRL proposals for the crops under assessments and for animal commodities. Adequate analytical methods for enforcement are available to control the residues of phosphonic acid on the commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg for high water- and dry matrices and at LOQ of 0.1 mg/kg in high acid matrices and in animal matrices and eggs at the validated LOQ of 0.05 mg/kg and in milk at the validated LOQ of 0.01 mg/kg. Based on the risk assessment results, EFSA concluded that the intake of residues resulting from the use of potassium phosphonates according to the reported agricultural practices is unlikely to present a risk to consumers.
