Review: Nutrient, Fiber, and Bioactive Content of Fruit Pomace, Major By-product of Juice Industry

Abstract

The market of the juice industry is increasing globally including in Indonesia and one of the factors that support the developing market of juice is the sufficient supply of raw material. Consequently, the increasing production of juice has resulted in a high amount of solid waste such as under-ripe fruits, rotten organic matter, peels, seeds, and majorly in the form of pomace. Pomace is usually discarded or slightly used as animal feed and becomes a serious environmental problem, and also an economic burden for the company. However, pomace can be utilized as functional and healthy ingredients in food product development due to its beneficial components namely dietary fiber and antioxidants. This review will emphasize on the nutrient, fiber and bioactive content of fruit pomace.

Influence of Particle Size and Extraction Methods on Phenolic Content and Biological Activities of Pear Pomace

“…There are several processing techniques to produce pear juice; the pear juice pressing process is the most commonly used. This juice extraction method produces 35% pomace with good nutritional quality as waste, which causes waste management, economic and environmental issues [3]. Pear pomace is highly perishable due to being 60-70% moisture and has been traditionally used as an additive to livestock feed or is wasted [4,5].…”
