Papaya seeds (Carica papaya L. var. Formosa) in different ripening stages: unexplored agro-industrial residues as potential sources of proteins, fibers and oil as well as high antioxidant capacity

Abstract

Considering the information presented above, the use of papaya seeds to obtain new products is a promising alternative, because it could add value to a by-product, provide new ingredients to the food industry, and diminish the disposal of agro-industrial wastes. Many studies have already evaluated different ways of extracting oil from papaya seeds (

High-Value Compounds in Papaya By-Products (Carica papaya L. var. Formosa and Aliança): Potential Sustainable Use and Exploitation

“…Also, papaya seeds contain lower amounts of linoleic acid, allowing a reduction in oxidation potential, and consequently, a longer shelf life to several products, which is an advantage for potential industrial applications in food, pharmaceutical, and cosmetic industries. Mesquita et al [2], Yao and Xu [37], and Santana et al [38] reported similar results for papaya oil seeds obtained from several papaya varieties. According to these researchers, papaya seeds may contain 30-40% of oil, making them as economically useful by-product.…”

“…Polyphenols have gained popularity in recent decades, owing mostly to their potential benefits to human health, resulting from their significant bioactivities (antioxidant, anti-inflammatory, antimicrobial, antidiabetic, among others) [2,11,40]. These bioactive molecules can be collected from by-products using several technologies and used to generate a variety of valorized products, such as functional foods or dietary supplements.…”

“…Papaya (Carica papaya L.) is a major subtropical and tropical horticulture crop. This fruit is recognized by its nutritional, health and medical characteristics [2,3]. Global papaya production is expected to increase 2.1%/year, reaching 16.6 million tons within five years [4].…”

Valorisation of goldenberry calyx: ultrasound-assisted extraction of phenolic compounds

“…Agricultural and food residues are the main organic waste produced worldwide, which could generate between 6 and 10% of greenhouse gas emissions (Teigiserova et al, 2020). In this context, the circular economy emerges as a strategy that seeks to mitigate the environmental impact generated by agro-industrial waste, giving it a new application in productive chains (León-Roque et al, 2023;Mesquita et al, 2023), for example, the extraction of bioactive compounds (Tirado et al, 2019).…”
