Problems solved by technology

In order to make better use of the remaining nutritional value of peanut dregs, there are foreign manufacturers of edible fiber. Due to the complicated process, high cost, and unobvious functionality, it has a slight odor when used in sausage and meat products, and the surface is not smooth. Affects food, so it is not widely used and cannot be popularized and utilized on a large scale

Embodiment 1

[0007] Embodiment 1: Take peanut residue with a moisture content of 75% and add it to a tempering tank, add process water at 90°C at the same time, mix and stir to make a peanut residue slurry with a moisture content of 90%, and then add food-grade hydrochloric acid with a concentration of 30%. Adjust the pH value to 5.0, keep the temperature at 80°C for one hour, add 30% sodium hydroxide, adjust the pH value to 8.0, add hydrogen peroxide, the dosage is 15L / t dry matter, keep the uniform state for one hour, put it into the high level tank for storage , into the filter press process. Put the peanut slurry into the filter press, the working pressure is 0.5MPa, the working temperature is 50°C, the thickness of the filter cake after the pressing is 30mm, and the water content is 55%. The press-filtered filter cake is sent to the flash dryer, the inlet air temperature in the internal steam dryer is 160°C, the exhaust air temperature after flash drying is 65°C, and the moisture cont...

Embodiment 2

[0008] Example 2: Get peanut residue with a moisture content of 85% and add it to a tempering tank, and simultaneously add process water with a temperature of 95°C to adjust to a peanut residue slurry with a moisture content of 95%, and then add food-grade hydrochloric acid with a concentration of 30%. The pH value is 5.5, keep the temperature at 85°C for 1 hour, add 30% sodium hydroxide, adjust the pH value to 9.0, add hydrogen peroxide, the dosage is 25L / t dry matter, keep it for one hour, put it into the high tank for storage, and then add pressure Filter, working pressure 0.8MPa, working temperature 55°C. The thickness of the filter cake after press filtration is 35mm, and the water content is 60%. The filter cake is sent to the flash dryer, the inlet air temperature is 165°C, the exhaust air temperature after flash drying is 70°C, and the moisture content of the filter cake after drying is 25%. Add the filter cake to the pulverizer for coarse grinding, grind it into unif...

Abstract

The invention relates to a preparation method of dietary fibers from peanuts, which comprises the following steps: wet peanut residues are taken as raw materials and proper amount of process water and accessories are added to prepare peanut residue pulps through hardening and tempering process; under certain conditions of temperature, time and environment, the peanut residue pulps respectively pass through various procedures to undergo chemical reaction and processing; the peanut residue pulps pass through a filter pressing procedure and are prepared into filter cakes with thickness of 20-40mm; the filter cakes are subjected to flash drying process and the dried filter cakes have moisture content of 15-20%; the filter cakes are broken up and are coarsely ground by flour mills to uniform powder; the powder is sterilized by microwave sterilizers and then is conveyed to a super micron mill for micronization to prepare the dietary fibers from peanuts; the dietary fibers have protein content more than or equal to 35%, moisture content less than or equal to 12%, ash content less than or equal to 6%, total content of dietary fibers more than or equal to 60%, water-holding capacity more than or equal to 20%, swelling coefficient more than or equal to 13ml / g and fineness of 100-380 meshes. The dietary fibers from peanuts can fully extract the nutritions in the peanut residues and have good quality, wide application, high added-value of products, high production efficiency, low production cost and good economic benefits.

Description

technical field [0001] The invention relates to food processing technology, in particular to deep processing technology of peanut by-products. Background technique [0002] Peanut, as a traditional oil crop, has a long history of planting and utilization in my country, and my country's peanut production ranks among the top in the world. Because peanuts have many uses, delicious taste and rich nutrition, peanuts and their products have become a popular food widely welcomed by the people for a long time. Peanut products are increasing day by day, and all kinds of peanut products will produce peanut dregs as a by-product after processing. Due to factors such as taste, flavor, and nutritional value that have dropped significantly, people can no longer eat it, and it is mostly used as feed or fertilizer. In order to make better use of the remaining nutritional value of peanut dregs, there are foreign manufacturers of edible fiber. Due to the complicated process, high cost, and ...
