“…EDTA is known to complex with Fe(II) [45,46] or with Fe(III), [46,60,64] therefore the complexation with EDTA was studied in this work. Note that, while EDTA has been used in food, [47,[65][66][67] the controversy among chemical additives has encouraged the search for natural alternatives. [67] However, in this study, EDTA was used as a model complexing agent.…”

The colorants found in beverages are sensitive to degradation resulting in a loss of color, which can affect the perception of the product quality by the consumer. The Fenton reaction is one of the possible degradation pathways. The Fenton oxidation process is a catalytic reaction of hydrogen peroxide (H2O2) with ferrous ions (Fe2+) that generates hydroxyl radicals able to degrade the organic molecules present in the solution. In this work, the effect of the Fenton reaction in colored model soft beverages was studied using UV–visible spectrometry. The naphtol blue black was selected as a benchmark dye because it can be easily followed to probe the Fenton process. The percent degradation of this synthetic dye in an aqueous solution at pH = 3.4, simulating conditions in beverages, was monitored in the presence of FeSO4 and H2O2. Other pHs (pH = 2.7, 6.1, and 10) were also tested to obtain a full picture of the phenomenon. In an attempt to prevent the dye degradation by the Fenton reaction occurring in beverages, the effect of the addition of EDTA, a chelating metal agent able to form complexes with iron ions, was evaluated, as a model. The effect of the EDTA concentration and the influence of the pH were also explored.

“…The components of EOs were studied and classified by EFSA, which provides an excellent database of food flavorings containing information on it [ 37 ], the FDA Office of Food Additive Safety (OFAS), and the Flavor and Extract Manufacturers Association of the United States (FEMA), founded in 1909, comprise flavor manufacturers, flavor users, flavor ingredient suppliers, and others with interest in the flavor industry, maintained available an online registered of flavorings, including EOs. Additionally, the International Organization of the Flavor Industry (IOFI), a global association representing the industry that creates, produces, and sells flavorings worldwide, provides excellent access to consult natural (complex) substance lists applied to food and feeds [ 38 ].…”

The use of nutraceuticals or functional ingredients is increasingly widespread in human food; their use is also widespread in animal feed. These natural compounds generally come from plant materials and comprise a wide range of substances of a very diverse chemical nature. In animals, these compounds, so-called phytogenics, are used to obtain improvements in feed production/stability and also as functional components with repercussions on animal health. Along with polyphenols, isoprenoid compounds represent a family of substances with wide applications in therapy and pet nutrition. Essential oils (EOs) are a group of complex substances with fat-soluble nature that are widely used. Melatonin is an indolic amine present in all living with amphiphilic nature. In this work, we present a review of the most relevant phytogenics (polyphenol, isoprenoid, and alkaloid compounds), their characteristics, and possible uses as nutraceuticals in dogs, with special emphasis on EOs and their regulatory aspects, applied in foods and topically. Additionally, a presentation of the importance of the use of melatonin in dogs is developed, giving physiological and practical aspects about its use in dog feeding and also in topical application, with examples and future projections. This review points to the combination of EOs and melatonin in food supplements and in the topical application as an innovative product and shows excellent perspectives aimed at addressing dysfunctions in pets, such as the treatment of stress and anxiety, sleep disorders, alopecia, and hair growth problems, among others.

Carmoisine is a type of azo dye , which is widely used in ice cram, soft drinks, sauces and with sweets and others . This study is designed to determine the effect of carmoisine dye (E122) on certain male rat vestal criteria ,including measuring the effectiveness of lipid profile (cholesterol levels .Triglycerides and high-density HDL fatty profile and low –density LDL ).The current study showed that there was an increase in the level of fat (Ch,TG,LDL) in the group of E122 injecting animals but it was observed that there was amoral reduction in the HDL level compared to the group of controlling animals and AgNPS animals
