Brazilian fruit processing, wastes as a source of lipase and other biotechnological products: a review

Abstract

The global food loss and waste is the most urgent research area in food science to attend the current demand for more sustainable and profitable processes. Along the productive chain about 1/3 of the food is lost or wasted, this number reaches 1/2 for fruit and vegetable production in developing countries. Brazil has been investing in researches aiming to turn its wastes into byproducts, as biomolecules of high value such as lipases. These enzymes are found in a high diversity of plant sources and their researches are covered by promising market growth expectations due to the current demand for biofuels and bio-transformed food. Thus, the aim of the present study is to discuss the potential of wastes generated by the Brazilian fruit processing to become a source of lipases, by the analysis of the most recent studies on fruit lipases, as well as the inclusion of this process in the biorefinery concept. According to this concept, different products can be obtained from the same raw material. Considering the confirmation of the presence of lipases on fruit wastes, the annual fruit production and the percentage of residues, the assessed data showed that wastes from the processing of orange, mango, papaya and palm are promising for lipase obtainment.

Brazilian Agro-industrial Wastes as Potential Textile and Other Raw Materials: a Sustainable Approach

“…Other fruits, not shown in the diagram, stand out, such as apple, khaki, avocado, and pomegranate for the removal of dyes (Bazzo et al 2016 ; Bonetto et al 2021 ; Silveira et al 2014a , b ); the seeds of açai in the adsorption and obtaining of fibers and application in composites (de Oliveira et al 2019a , b ; Wataya et al 2016 , 2015 ; Zavarize 2021 ); cashew and acerola for bionanocomposites (Duarte et al 2015 ; Vieira Amorim et al 2021 ); cocoa husks for cellulose nanofiber (Souza et al 2019 ); and papaya and mango for the generation of enzymes for the textile industry (Okino-Delgado et al 2018 ). The cereal group also presents incidence of moreover materials, such as oat husks for the generation of nanofibrillated cellulose (Debiagi et al 2021 ).…”

Evaluation of the lipidic composition and antioxidant activity of the seed oil from grapes ‘Isabel’ and ‘Rose Niagara’

“…However, E vitamin is prone to decomposition, which ends up reducing the overall antioxidant activity of the oil. The early stages of winemaking may also play an important role in the degradation of the antioxidant compounds in the grape seed and pomace (BANEZ et al, 2020;OKINO-DELGADO et al, 2018).…”

Simple and Efficient Process for Valorization of Orange Peel Waste for Isolation and Purification of Industrially Important Lipase

“…There are several agro-industrial as well as fruit and vegetable waste feedstocks such as orange peels, banana peels, mango peels, grapes peels and seeds, coconut peels, papaya peels and seeds, castor and palms bagasse reported for the presence of lipase naturally. 17 Thus, the exploration of these feedstocks as a direct source for lipase isolation can be a good value addition as well as potential replacement to other complex methods for lipase production. Reference 18 reported for the first time the potential of orange juice processing waste (peel, frit, and core) for production of lipase and isolated lipase with enzyme activity of 68.5 U/g from orange peel.…”
