In the study, which was published in the Journal of Food Processing and Preservation, the researchers sought to find a way to make use of food processing residues as natural colorants for food and beverages that are rich in bioactive compounds. They evaluated the stability and retention of anthocyanins from grape byproducts as a source of food colorant in kefir and carbonated water during storage.
Based on the results, anthocyanins from grape skins added to kefir and carbonated beverages provided color to these drinks. In addition, they exhibited better thermal stability and had longer shelf-life when stored in the dark compared to when they were exposed to light. Moreover, grape skin anthocyanins also provide health benefits because of their antioxidant properties. Earlier studies have shown that anthocyanins can protect the heart from diseases, prevent obesity, and ward off cancer.
From these findings, the researchers concluded that anthocyanins from grape skins can be used as a healthy and natural colorant in food and drinks, which can be used as an alternative for synthetic food colorants. The findings of the study are important because artificial food colorants used by many food manufacturers are harmful to health. In addition, these findings present a new way to reduce food wastes by the food industry that harm the environment and cause economic losses.
Artificial food dyes may make food and beverages appealing, but they actually are harmful to your health. Here are some reasons why you should stop consuming foods with artificial food dyes:
To completely avoid these toxic ingredients, always check the labels carefully when buying food. Avoid products that say "color added," or those that contain Red 40, Yellow 5, and Yellow 6. Most foods that contain artificial food colorants include frosting, sprinkles, soda, and candies. Juice and pre-packed meals can also be dyed. White products, such as white cake frosting, can also be dyed to look even whiter. Food dyes can also be found in personal care products, such as toothpaste and mouthwash.
