Abstract

Carrot pomace has polyphenols in large amounts. Polyphenols play an important role in the prevention of degenerative diseases such as cancer and cardiovascular diseases. Carrot pomace goes to waste with all these useful compounds. Carrot pomace or its extract can be utilized in food products to combat food shortage. Extraction of molecules from biological materials by conventional techniques, such as simple maceration, is time consuming. Sonication breaks the cell membranes. It reduces considerably the extraction time and increasing the extract yield. These phenolics were extracted using conventional Maceration techniques & advance Sonication technique. The extracts were used in Functional date-oat bars. Bars were then tested for determination of total phenolics present in them. Total Polyphenol content of functional date bar having 1% extract were 3.160 mg GAE/g of extract. Antioxidant activity in terms of % inhibition of functional date bar having 1% extract is 26.70%. It is evident from the results that the extracts of carrot pomace contain significant number of polyphenols and anti-oxidant activity. The potential of reducing waste to combat the food security issues are high, as it is estimated that by 50% reduction in current food waste, the world would be saving 1314 trillion kcal per year. This represent a reduction of about 22% of the number of additional calories needed to feed the projected population by 2050.
