RETRACTED: Utility of apple pomace as a substrate for various products: A review

Abstract

In large scale apple juice industry, about 75% of apple is utilized for juice and the remaining 25% is the by-product, i.e. apple pomace. In India, more than 500 apple processing industries produces 1.3 million tonnes of apple pomace per annum which involves an annual disposal expenditure of $10 million. Generally, apple pomace is thrown away which causes environmental pollution and only approximately 10,000 tonnes of apple pomace is being utilized. As pomace is a part of the fruit, it has potential for being transformed into various edible and industrial products. It is a rich source (amount per 100 g) of carbohydrate (11.8 g), pectin (16.95 g), crude fibre (2.3 g) and minerals (0.3 g) and as such is a good source of nutrients. This paper reviews the work done to utilize this precious resource which can prove useful for setting up of small scale industries.
