Abstract:
Today, there is an increasing interest in antioxidants, especially to prevent the known harmful effects of free radicals in human metabolism and their deterioration during processing and storage of fatty foods. In both cases, natural-source antioxidants are preferred over synthetic antioxidants. So, there has been a parallel increase in the use of assays to estimate antioxidant efficacy in human metabolism and food systems. Today, there are many bioanalytical methods that measure the antioxidant effect. Of these, the 1,1-diphenyl-2-picrylhydrazil (DPPH) removing assay is the most putative, pop

Abstract:
The consumption of foods that are high in antioxidant capacity is believed to contribute to good health. Moreover, the addition of highly antioxidant compounds to foods is believed to prevent food deterioration. Among the known antioxidants in food, phenols have been identified as the primary antioxidants. The 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay is a simple, inexpensive, and rapid method widely used to evaluate the antioxidant capacity. Although the results of the DPPH assay depend on conditions such as the reaction time and concentration, the experimental conditions have not been stand

Abstract:
Cellular damage can arise from the reactions of free radicals with membrane lipids, nucleic acids, proteins, enzymes, and other micro molecules. Free radical-induced cell damage seems to be a primary factor in the aging process and degenerative diseases, including but not limited to cancer, heart disease, cataracts, liver disorders, diabetes mellitus, inflammation, and renal failure. Naturally, the body produces free radicals, and antioxidants scavenge them to shield the body from harmful consequences. This dynamic equilibrium exists between the two.

Abstract:
Vegan alternatives to cheeses are in growing demand in European markets as more and more people are either lactose intolerant or switching to a plant-based diet. When the consumer chooses to buy a vegan cheese, his expectations are that the vegan product has the nutritional and organoleptic characteristics as similar as possible to those of conventional cheeses. This work aimed to obtain two variants of vegan alternative to cheese, using coconut milk as the raw material: one with the addition of white pepper and garlic powder (C1) and the second with the addition of turmeric and paprika (C2).
