Abstract
The cashew (Anacardium occidentale) is a tree native to Brazil and later introduced in Asia and Africa.
Vietnam leads its production with 4.89 million t; Latin America contributes 8% of world production.
Colombias production in 2019 was 128,121 t with a yield of 3.6%, the fruit of the tree is composed of the nut, which is highly commercialized and exported, and a peduncle or also called apple, or false fruit (pseudo fruit). The ratio between the pseudo fruit and the nut is 9:1, meaning 1 t of cashew nuts corresponds to 10 to 15 t of lost pseudo fruit, which has a negative environmental impact.
The objective of this study was to evaluate the content of total phenols and the antioxidant capacity of the pseudo fruit and by-products such as natural fruit juice beverages and juice with Aloe vera crystals, dip-type spreadable products (flavors: natural, pineapple, red fruits, paprika, and garlic) and flour obtained from pseudo fruit processing during juice extraction, to add value to pseudo fruit.
After preparing the extracts (deionized water and 96% ethanol of the other products), FRAP, ABTS, DPPH, led to calculating the antioxidant capacity and calculating the scavenging of free radicals for the last two and the content of total phenols.
A higher % of DPPH free radical scavenging was identified in fruit, followed by beverages and juice with aloe vera (70, 56, and 63%, respectively). The content of total phenols is higher in fruit, drinks, and flour and lower in spreadable products.
The pseudo fruit of the cashew could be a highly usable product, contributing positively to the environmental impact and generating new product alternatives.
