Embodiment 1

[0028] During the processing of passion fruit pulp, the raw materials of passion fruit are divided mechanically or manually, and after separating the pulp with seeds, half-divided passion fruit peels are obtained. The seeded pulp is processed into passion fruit pulp.

[0029] The passion fruit peel is placed in the extraction tank, and the four-stage countercurrent hot water extraction method is used for processing. The specific steps are: use 5 extraction tanks to form a production line, the weight ratio of the peels in each extraction tank to the production water is 1:8~1:10, extract for 3~6 minutes respectively, and the peels of each tank are in the tank. Afterwards, it is not discharged from the bottom of the tank until the fourth leaching is finished; while the production water flows between the tanks in a countercurrent manner for leaching, that is: after the passion fruit peel Ⅰ is loaded into the leaching tank 1, the water is extracted by the leaching tank 1. The extr...

Embodiment 2

[0033] After the passion fruit raw materials are purchased and accepted, the peels in half are obtained after cleaning, manual cutting in half and pulping. use figure 2Shown flow process, each 100kg of passion fruit skin is packed into extraction tank 1,2,3,4 respectively, in each extraction tank, add the hot water of 800kg100 ℃, carry out solid-liquid separation after insulation extraction 3min, wherein, The peels in the extraction tanks 4, 3, and 2 were extracted 3 times, 2 times, and 1 time respectively, and the 4 jars of peels that had been extracted 3 times, 2 times, and 1 time respectively were obtained as the initial stage of countercurrent extraction. materials. Then start countercurrent extraction, inject 1000 kg of normal temperature production water A into the extraction tank 4 to cool for 2 minutes, and the liquid obtained through solid-liquid separation is heated to 80 ° C, that is, the extraction solution B, and the extraction solution B is poured into the extr...

Embodiment 3

[0035] After the leaching solution E is coarsely filtered by a duplex filter to remove impurities, ultrafiltration is performed with a 100KD ultrafiltration membrane to obtain an ultrafiltration permeate, and the ultrafiltration permeate is subjected to secondary reverse osmosis equipment under a pressure of 3MP. Reverse osmosis treatment, concentrating until the soluble solid content in the reverse osmosis retentate is higher than 20%, and collecting the reverse osmosis permeate and the reddish-brown reverse osmosis retentate respectively. The reverse osmosis permeate is reused as production water A, thereby reducing the consumption of water resources; while the reverse osmosis retentate enters the next production section.

[0036] The pericarp in the extraction tank 4 is cooled by the production water A, and the pericarp is discharged after solid-liquid separation. Now, the leaching work of the pericarp in the extraction tank 4 is all completed, and what is discharged is the...

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...
