Abstract

The invention discloses a method for producing dietary fiber nutrient powder by using citrus peeling waste residue and the citrus dietary fiber nutrient powder prepared by the method. The method comprises the following steps of: mincing the citrus peeling waste residue, and regulating the water content to be 15 to 20 percent; treating for 30 to 60 minutes at the temperature of between 15 and 35 DEG C by adopting ultrasonic wave; regulating the pH value to be neutral by using NaOH and HAc; inoculating spore suspension of trichoderma koningii to the minced citrus peeling residue with regulated pH value, culturing at the temperature of between 26 and 30 DEG C, and fermenting for 2 to 3 days; performing extrusion, wherein the rotating speed of a screw of an extruder is controlled to be 90-130r / min, and the extrusion temperature is controlled to be 120-150 DEG C; and cooling and crushing the extruded granules, sieving with a sieve of 60 meshes, and thus obtaining the citrus dietary fiber nutrient powder. The invention has the advantages of simple steps, high resource recycling rate, good economic benefits, environment friendliness and capability of obtaining a product with high nutritional value.

Description

technical field [0001] The invention relates to the technical field of comprehensive recycling of citrus, in particular to a process method for comprehensive recycling of citrus capsules. Background technique [0002] Citrus fruits are one of the most produced fruits in the world. my country is the largest producer of citrus in the world, with the planting area and output ranking first in the world. Canned citrus is the leading product of citrus processing in my country, accounting for about 70% of the international market, and it is also the most competitive product of my country's citrus industry in the international market. The process of canned citrus includes the process of decapsulation. The traditional method is to use acid-base decapsulation, and the modern method is to use enzymatic decapsulation. However, no matter whether it is acid-base or enzyme preparation, capsule waste residue will be generated. The waste residue mainly includes the by-products of processin...
