“…Alternatively, waste orange peel can also be converted into fertilizer by co‐composting with organic fraction of municipal solid waste, which helps to reduce soil erosion. Siles, Vargas, Gutiérrez, Chica, and Martín () observed that co‐composting of waste orange peel combined with organic fraction of municipal solid waste resulted in 37% reduction in odor generated compared to single organic fraction of municipal solid waste.…”

Citrus fruits are major processed fruits in the world that results in generation of large quantities of by‐products, which are rich sources of soluble sugars, cellulose, hemicellulose, pectin, and essential oils. However, very large amount of residues is end up at agriculture field or dumping pit as waste. The present review highlights the technologies and processes for utilization of the citrus by‐products viz., feed for extraction of essential oils, charcoal and bio‐oil production, hydrogen syngas etc. Citrus pulp a very effective agent for removal of metals and chemicals in and effluent generated by industries by adsorption technique. Polymer Electrolyte Membrane Fuel Cell developed by synthesis of activated carbon from citrus pulp is considered to be next generation potential power. In order to make rational use of this valuable resource and protect the environment, the present study aims at comprehensive utilization of this value added by‐products. Practical Applications In the present scenario of fast developing world, the generation of waste is increasing day by day in large quantities which influences the heath of ecosystem and ultimately the human health. Adaptation of advanced technologies and processes is not only a technique of waste management but also generate an alternative to environment polluting substances through development of craft paper, biodiesel, activated carbon along with development of value added food products such as extruded, pectin extraction, essential oils, etc. Increased scope of product development increases the overall returns to manufacturer, employment generation and sustainable socio‐economic development and maintains environmental stability.

“…These bioactive compounds comprise approximately 0.1-0.5% of citrus peel dry weight. The major carotenoids available in citrus are α-and β-carotene, lutein, zeaxanthin and β-cryptoxanthin, which are known to be responsible for a wide range of functional properties, mainly offering protection against the reactive oxygen species damaging actions at the cellular level [64,[82][83][84]]. …”

Food industry produces worldwide millions of tons of plant-derived wastes which can be exploited as sources of high-value components: proteins, fibres, polysaccharides, flavour compounds or different phytochemicals. These bioactive compounds can be valorised as functional ingredients in food, pharmaceutical, health care, cosmetic and other products. Using the recovered bioactive molecules as functional ingredients represents a sustainable alternative of food wastes exploitation as inexpensive source of valuable compounds, while developing innovative food and non-food products with health-promoting benefits and at the same time contributing to an efficient waste reduction management. This chapter gives an overview of the main classes of bioactive compounds recovered from food wastes and their potential applications as functional chemicals, without being exhaustive.

“…Grape pomace is made up of stalks (~2%), seeds (~47%), skin, and pulp (~51%) [12,13]. Citrus and grape by-products are largely treated as waste and generally disposed of in landfills [14]. The high moisture and organic contents of these fruit by-products upon putrefaction, poses a significant risk to the environment through production of greenhouse gasses and contamination of water bodies [14].…”

Food Preservative Capabilities of Grape (Vitis vinifera) and Clementine Mandarin (Citrus reticulata) By-products Extracts in South Africa

The drive towards sustainable food systems coupled with increased consumer sophistication have prompted innovation in waste valorization. Grape and citrus processing by-products, abundant in the Mediterranean and tropical regions, respectively, are expanding and are sustainable sources of bioactive phytochemicals that can be used as natural preservatives for foods. Phytochemical composition, antioxidant, and antimicrobial properties of extracts from grape pomace (GPE), seeds (GSE), and clementine mandarin peel and pulp (MPE) grown in South Africa were analyzed. Total phenols and carotenoids were highest in GPE followed by GSE and MPE (p ≤ 0.05). Flavonoids and anthocyanins were higher (p ≤ 0.05) in GPE and GSE compared to MPE. The GSE had the highest proanthocyanidins content followed by GPE and MPE (p ≤ 0.05). Ascorbic acid was only detected in MPE, which also had the highest titratable acidity and lowest pH values (p ≤ 0.05). The GSE had the highest antioxidant potency composite index followed by GPE and MPE (p ≤ 0.05). The order of antimicrobial activity of the extracts was MPE > GSE > GPE (p ≤ 0.05). Current findings show that GSE is a potential antioxidant while MPE holds promise as an antimicrobial for the food industry.
