A Review on the Potential Bioactive Components in Fruits and Vegetable Wastes as Value-Added Products in the Food Industry

Abstract

The food production industry is a significant contributor to the generation of millions of tonnes of waste every day. With the increasing public concern about waste production, utilizing the waste generated from popular fruits and vegetables, which are rich in high-added-value compounds, has become a focal point. By efficiently utilizing food waste, such as waste from the fruit and vegetable industries, we can adopt a sustainable consumption and production pattern that aligns with the Sustainable Development Goals (SDGs). This paper provides an overview of the high-added-value compounds derived from fruit and vegetable waste and their sources. The inclusion of bioactive compounds with antioxidant, antimicrobial, and antibrowning properties can enhance the quality of materials due to the high phenolic content present in them. Waste materials such as peels, seeds, kernels, and pomace are also actively employed as adsorbents, natural colorants, indicators, and enzymes in the food industry. Therefore, this article compiles all consumer-applicable uses of fruit and vegetable waste into a single document.

Exploration of novel eco-friendly techniques to utilize bioactive compounds from household food waste: special reference to food applications

“…Extracted components from food waste (FW) containing sugars, proteins, fibers, pectin, lipids, polysaccharides, taste compounds, and phytochemicals are employed as food additives, nutraceuticals, pharmaceuticals, and cosmetics. This increases food availability, extends shelf life, and minimizes landfill waste (Aqilah et al, 2023). Polymers made from renewable organic sources, known as "bio-based polymers", diminish reliance on fossil fuels and are produced from agroindustrial waste through combined fermentation and enzymatic processes.…”

Therapeutic Potential of Polyphenols and Other Micronutrients of Marine Origin

“…While ellagic acid is most commonly found in fruits and vegetables, such as strawberries, raspberries and pomegranates, it has also been identified in some species of fish. For example, research has shown that ellagic acid can be found in the muscle tissue of salmon and trout ( Oncorhynchus mykiss ) [ 116 ]. It is important to note, however, that the amount of ellagic acid present in fish is typically much lower than that found in fruits and vegetables.…”

Valorization of Potato Peel Waste as Natural Additive for Use in Meat Products

“…The presence of nutrients and bioactive compounds in peel waste makes it a potential ingredient to be incorporated during meat products formulation [24]. Table 1 shows the results of the chemical proximate composition of potato peel waste powder and meat product treated with this waste.…”
