Studying the impact of 3d printing technology on safety indicators of plant-based burger.

This study investigate the impacts of 3D printing technology on safety indicators in plant-based burgers. Experiments were performed in the refrigerator on days 0, 5, 7, 12, and 14 and at room temperature at 0, 24, and 96 h after printing. On days 7 and 12 in the refrigerator, PTC of printed samples was significantly higher than conventional. On day 1, the printed sample had higher pH, but on the other days, the pH decreased and no significant difference was reported. TVBN showed a significant (p < 0.05) increase in the refrigerator and room. Peroxide value and TBARS increased (p < 0.05) in all groups and the printed sample showed a higher value, which could be due to porosity during printing. The results of the sensory showed that the appearance and overall acceptance of the 3D printed sample were significantly (p < 0.05) higher than the conventional sample.

Zearalenone, an estrogenic component, in bovine milk, amount and detection method; A systematic review and meta-analysis.

Zearalenone (ZEN) and its metabolites are a potent component with estrogenic potential that can enter milk. ZEN and its metabolites have the ability to disturb the function of endocrine glands. The aim of this systematic review was to estimate the level of ZEN and its metabolites in milk. This study was performed with these keywords; zearalenone, ZEN, bovine milk, ruminant milk, milk, dairy products, and milk product in various databases. 946 manuscripts were collected from databases and at the end, 17 manuscripts were reviewed according to the inclusion criteria. ZEN was identified in 59 % of studies. The most common methods of analysis were UHPLC, HPLC and ELISA. Meta-analysis was performed with CMA (Comprehensive Meta-Analysis) software. No publication bias was observed in meta- analysis. But, heterogeneity was recorded between studies. The measurement method was identified as one of the sources of heterogeneity through meta-regression tests and subgroup analysis. Furthermore, in meta- analysis test, the total estimate of milk contamination with this mycotoxin was 0.036±0.017 µg/L. So far, the permissible limit for this compound in milk has not been announced, but these compounds have the ability to disturb the endocrine glands in low amounts. Therefore, it is necessary to regularly measure and control this mycotoxin and its metabolite in milk with valid methods.

Personalized nutrition with 3D-printed foods: A systematic review on the impact of different additives.

Three-dimensional (3D) printing is one of the world's top novel technologies in the food industry due to the production of food in different conditions and places (restaurants, homes, catering, schools, for dysphagia patients, and astronauts' food) and the production of personalized food. Nowadays, 3D printers are used in the main food industries, including meat, dairy, cereals, fruits, and vegetables, and have been able to produce successfully on a small scale. However, due to the expansion of this technology, it has challenges such as high-scale production, selection of printable food, formulation optimization, and food production according to the consumer's opinion. Food additives (gums, enzymes, proteins, starches, polyphenols, spices, probiotics, algae, edible insects, oils, salts, vitamins, flavors, and by-products) are one of the main components of the formulation that can be effective in food production according to the consumer's attitude. Food additives can have the highest impact on textural and sensory characteristics, which can be effective in improving consumer attitudes and reducing food neophobia. Most of the 3D-printed food cannot be printed without the presence of hydrocolloids, because the proper flow of the selected formulation is one of the key factors in improving the quality of the printed product. Functional additives such as probiotics can be useful for specific purposes and functional food production. Food personalization for specific diseases with 3D printing technology requires a change in the formulation, which is closely related to the selection of correct food additives. For example, the production of 3D-printed plant-based steaks is not possible without the presence of additives, or the production of food for dysphagia patients is possible in many cases by adding hydrocolloids. In general, additives can improve the textural, rheological, nutritional, and sensory characteristics of 3D printed foods; so, investigating the mechanism of the additives on all the characteristics of the printed product can provide a wide perspective for industrial production and future studies.

Assessment of cheese frauds, and relevant detection methods: A systematic review.

Dairy products are widely consumed in the world due to their nutritional and functional characteristics. This group of food products are consumed by all age groups due to their health-giving properties. One of these products is cheese which has a high price compared to other dairy products. Because of this, it can be prone to fraud all over the world. Fraud in food products threatens the world's food safety and can cause serious damage to human health. There are many concerns among food authorities in the world about the fraud of food products. FDA, WHO, and the European Commission provide different legislations and definitions for fraud. The purpose of this review is to identify the most susceptible cheese type for fraud and effective methods for evaluating fraud in all types of cheeses. For this, we examined the Web of Science, Scopus, PubMed, and ScienceDirect databases. Mozzarella cheese had the largest share among all cheeses in terms of adulteration due to its many uses. Also, the methods used to evaluate different types of cheese frauds were PCR, Spectrometry, stable isotope, image analysis, electrophoretic, ELISA, sensors, sensory analysis, near-infrared and NMR. The methods that were most used in detecting fraud were PCR and spectrometry methods. Also, the least used method was sensory evaluation.

Fortification of chocolates with high-value-added plant-based substances: Recent trends, current challenges, and future prospects.

High consumption of delicious foods, such as chocolates, is considered excellent snacks, capable of converting from health-threatening to great functional foods. The fortification of chocolates with high-value-added plant-based substances might improve their healthful effects, nutritional properties, and shelf life. Chocolate could be an effective carrier for plant-based substances delivery, and it could be an effective vehicle to treat and reduce the indications of disease, such as obesity, overweight, hypertension, stress, cardiovascular failure, congestive heart failure, and diabetes. Referring to the recent studies in chocolate fortification with high-value-added plant-based substances, it seems that the recent trends are toward its therapeutic effects against noncommunicable diseases. Despite the undeniable functional effects of fortified chocolates, there are some challenges in the fortification way of chocolates. In other words, their functional characteristics, such as rheological and sensory attributes, may undesirably change. It seems that encapsulation techniques, such as spray drying, antisolvent precipitation, nanoemulsification, and liposomal encapsulation, could almost overcome these challenges. Thus, several studies focused on designing and fabricating nanoscale delivery systems with the aim of chocolate fortification, which is discussed.

Association between food additives and prevalence of allergic reactions in children: a systematic review.

Food additives contain synthetic and natural chemical compounds and are one of the causes of food allergies. In this regard, it is necessary to recognize the food additives that are of special interest for children. In this survey, the relation between food additives and allergic reactions and attention-deficit hyperactivity disorders in children was studied. The research studies with keywords "allergic reactions", "hypersensitivity", "food additives" and "children" were searched in PubMed, Scopus, Science Direct, Web of Science, and SID databases, from 1984 to 2020. Three hundred twenty-seven studies were obtained and only seven articles were finally selected according to exclusion and inclusion criteria. In the final review, seven articles were selected to investigate the relationship between food additives and hypersensitivity reactions. Some clinical factors such as urticaria, eczema, rhinitis and gastrointestinal symptoms and the prevalence of laboratory evidence in atopic children are due to increased exposure to food additives including artificial colors and sweeteners, preservatives, and monosodium glutamate. Clinical signs and laboratory evidence prove a significant association between some food additives and allergenic adverse reactions. It was also found that food additives such as artificial colors and sweeteners, preservatives, and monosodium glutamate are responsible for most cases of hypersensitivity in children, and the prevalence of hypersensitivity to food additives was estimated to be about 1.2% based on data extracted from studies.

Acrylamide; a neurotoxin in popcorns: a systematic review and meta-analysis.

Acrylamide is a known neurotoxic compound for humans. Foods that have high concentrations of acrylamide need to be identified. One of the food products containing acrylamide is popcorn. Popcorn is an important source of snacks for children, especially students. The presented study is a systematic review and meta-analysis of the level of acrylamide in popcorn. The search was done in different databases with the keywords; acrylamide, popcorn, popped corn. 27 articles were found by searching various databases. After initial screening and full text evaluation, 8 articles were selected for systematic review and 6 articles for meta-analysis. The amount of acrylamide in this product was in the range of 1,017.7-106 µg/kg. Microwaved corn contains lower amounts of acrylamide than other methods of preparation. The type of popcorn also had an effect on the amount of acrylamide with Meta-regression. It was found that sweet popcorn contains higher amounts of acrylamide. The overall value of acrylamide concentration in popcorns was calculated to be 459.6 ± 220.3 µg/kg. This amount is high and requires measures to reduce the amount of acrylamide.

Acrylamide content of industrial and traditional popcorn collected from Tehran's market, Iran: A risk assessment study.

Acrylamide as a probable human carcinogen can be produced via the Maillard reaction between asparagine and reducing sugars at high temperatures during food processing. In this study, the concentration of acrylamide in industrial and traditional popcorn sold in Tehran, Iran in the spring of 2021 was analyzed. Industrial popcorn is popcorn that has a manufacturing license from the health authorities. Traditional popcorn is sold by retailers in entertainment centers. Estimated daily intake (EDI) and margin of exposure (MOE) for neurological changes and neoplastic effects have been estimated. The values of limit of detection (LOD) and limit of quantitation (LOQ) were determined as 3.1 and 10.2 ng/mL, respectively. The amount of acrylamide was measured ranging from nondetectable up to 14.8 mg/kg. Acrylamide was detected in 86% of samples. The level of acrylamide in most popcorn samples has been detected as greater than LOD and LOQ. The average content of acrylamide in traditional popcorn was determined to be 7.7 mg/kg which was higher than the average value of 3.08 mg/kg found in industrial popcorn. Significant difference was observed between industrial and traditional popcorn samples. The average intake of popcorn for adolescent population was estimated as 2 g per day. EDI was calculated as 0.3 and 0.12 µg/kg of body weight per day for the traditional and industrial popcorn. These results indicated that popcorn can be considered a potential source of acrylamide exposure in the adolescent population. Furthermore, if the actual MOEs for neurological and neoplastic effects are estimated to be less than 10 000, it is considered a health risk. In this study, MOE has been estimated lower than 10 000 for neurological changes and neoplastic effects.
