Sources and Absorption of Resveratrol
Polyphenols are secondary metabolites produced by plants and also found in many natural products, such as fruit and vegetables, and their derivatives, such as tea, coffee, olive oil, and wine. Polyphenols are well known for their antioxidant properties, which confer to them health-beneficial effects. Among them, resveratrol is probably one of the most investigated molecules. It was first described in 1940 by Michio Takaoka, a Japanese student who was investigating extracts from traditional medicinal plants and called it “resveratrol” because the molecule had been extracted from the roots of Veratrum grandiflorum (white hellebore) and presented the skeleton of resorcinol in its molecular structure. The extract from this plant was exploited for treating several allergic and inflammatory diseases, among others. However, this molecule did not attract much interest until 1997, when Jang and colleagues published an article regarding its cancer chemopreventive activity. Resveratrol is the common name for 3,5,4′-trihydroxy-trans-stilbene, a natural phytoalexin derived from phenylpropanoids, that is synthesized in plants under stress conditions, such as infections or UV exposure.

Diploid Wheats and Non Celiac Wheat Sensitivity
Non-celiac wheat sensitivity (NCWS) is a clinical entity induced by the ingestion of gluten that leads to intestinal and/or extraintestinal symptoms, and is diagnosed when celiac disease and wheat allergy have been ruled out. In addition to gluten, other grains’ components, including amylase trypsin inhibitors (ATIs) and fermentable short-chain carbohydrates (FODMAPs), may trigger symptoms in NCWS subjects. Several studies suggest that, compared with tetraploid and hexaploid modern wheats, ancient diploid wheats species could possess a lower immunogenicity for subjects suffering from NCWS.

Common Mycotoxins in Cereal Grains and Producing Fungi
Cereal grains are the most important food staples for human beings and livestock animals. They can be processed into various types of food and feed products such as bread, pasta, breakfast cereals, cake, snacks, beer, complete feed, and pet foods. However, cereal grains are vulnerable to the contamination of soil microorganisms, particularly molds. The toxigenic fungi/molds not only cause quality deterioration and grain loss, but also produce toxic secondary metabolites, mycotoxins, which can cause acute toxicity, death, and chronic diseases such as cancer, immunity suppression, growth impairment, and neural tube defects in humans, livestock animals and pets.

Tobacco Carbohydrates as Bioactive Compounds
Carbohydrates are important compounds in natural products where they primarily serve as a source of energy, but they have important secondary roles as precursors of aroma or bioactive compounds. They are present in fresh and dried (cured) tobacco leaves as well. The sugar content of tobacco depends on the tobacco variety, harvesting, and primarily on the curing conditions (temperature, time and moisture). If the process of curing employs high temperatures (flue-curing and sun-curing), final sugar content is high. In contrast, when air curing has a lower temperature, at the end of the process, sugar level is low. Beside simple sugars, other carbohydrates reported in tobacco are oligosaccharides, cellulose, starch, and pectin. Degradation of polysaccharides results in a higher yield of simple sugars, but at the same time reduces sugars oxidization and transfer into carbon dioxide and water. Loss of sugar producers will compensate with added sugars, to cover undesirable aroma properties and achieve a better, pleasant taste during smoking.

Actual Application of Propolis
Propolis is a natural hive product collected by honeybees from different plants and trees. The collected resins are then mixed with bee wax and secretions. Propolis has a long history of use in traditional and alternative medicine. Propolis possesses recognized antimicrobial and antioxidant properties. Both properties are characteristics of food preservatives. The antimicrobial and antioxidant properties of propolis were extensively studied. In addition, propolis is recognized as safe (GRAS) and can be considered as an alternative to chemical preservatives. Before its use in food products, propolis was in most cases extracted using different solvents such as ethanol, water, and glycerol. Each solvent offers advantages and disadvantages. Ethanol extracts (PEE) are reported to be the richest extracts in bioactive components. While water extracts (WPE) are the lowest extract on phenolic content. In contrast, the two extracts exhibited a strong flavor and aroma.

Mitigation of Peanut Allergenicity
Peanuts are the seeds of a legume crop grown for nuts and oil production. Peanut allergy has gained significant attention as a public health issue due to its increasing prevalence, high rate of sensitization, severity of the corresponding allergic symptoms, cross-reactivity with other food allergens, and lifelong persistence. Given the importance of peanuts in several sectors and taking into consideration the criticality of their high allergic potential, strategies aiming at mitigating their allergenicity are urgently needed. In this regard, most of the processing methods used to treat peanuts are categorized as either thermal or thermomechanical techniques. They differ in their effectiveness in alleviating the allergenicity, and in their capacity in preserving the structural integrity of the treated peanuts. Research data on this matter may open further perspectives for future relevant investigation ultimately aiming at producing hypoallergenic peanuts.

DNA-Based Animal Species Authentication in Dairy Products
Milk is one of the most important nutritious foods, widely consumed worldwide, either in its natural form or via dairy products. Currently, several economic, health and ethical issues emphasize the need for a more frequent and rigorous quality control of dairy products and the importance of detecting adulterations in these products. For this reason, several conventional and advanced techniques have been proposed, aiming at detecting and quantifying eventual adulterations, preferentially in a rapid, cost-effective, easy to implement, sensitive and specific way. DNA-based methods relying on polymerase chain reaction (PCR) have been widely applied to detect adulterations in foods from both plant and animal origins, including dairy products because of their simplicity, high sensitivity and high specificity. They benefit from the high thermal stability of DNA molecules, which is particularly relevant when analysing processed foods, and are independent from immunochemical recognition, making them not susceptible to cross-reactivity. The ubiquity of nucleic acids in every type of cell and particularity in healthy mammary glands, which have high numbers of leucocytes and epithelial cells that are transferred to the milk, is another advantage to highlight. During cheese making, these cells are concentrated and allow the isolation of DNA to discriminate the species.
