Full-utilization comprehensive processing process for improving value of passion fruit peels

Abstract

The invention discloses a full-utilization comprehensive processing process for improving the value of passion fruit peels. The process comprises the following steps: performing heat treatment on the passion fruit peels by a multistage backflow hot water extraction method to obtain last-stage extraction liquid and heat-treated passion fruit peels; performing rough filtration, ultrafiltration and reverse osmosis treatment on the last-stage extraction liquid to obtain reverse osmosis permeation liquid and reverse osmosis trapped liquid; adding maltodextrin into the reverse osmosis trapped liquid, and performing spray-drying to obtain passion fruit peel extract; separating the heat-treated passion fruit peels to obtain cuticle peels and sponge layer peels; crushing the sponge layer peels, and mixing the crushed sponge layer peels with passion fruit pulp and honey to obtain honey and passion fruit tea; drying and grinding the cuticle peels to obtain dehydrated cuticle peel powder, and processing the dehydrated cuticle peel powder into a livestock and poultry feed. The process has the advantages that the sponge layer peels have complete shape, color and mouth feel, the active ingredient content of the passion fruit peel extract is relatively high, the passion fruit peels are processed into various products, the complete passion fruits are fully utilized, and no fruit solid waste residues are discharged.

Description

technical field [0001] The invention relates to a method for emission reduction and comprehensive utilization of agricultural product processing waste, in particular to a comprehensive utilization and comprehensive processing technology for increasing the value of passion fruit peel. Background technique [0002] Passion fruit, also known as passion fruit, is a subtropical special fruit. Its pulp has high acidity, strong flavor and rich nutrition. It is an excellent raw material for subtropical fruit juice processing. However, most of the passionflower processing enterprises discard the peel after processing the pulp. The pericarp as processing waste accounts for about 50% of the whole fruit of passion fruit. Its disposal not only increases the cost of the enterprise, but also reduces the benefit, and also wastes a lot of agricultural resources and pollutes the environment. The utilization of the pericarp is very necessary And meaningful. [0003] Existing more relevant pa...
