Embodiment Construction

[0008] The bamboo shoot heads removed from the processing of bamboo shoots are removed from the shells and soil, placed in a drum-type fruit washing machine, cleaned and drained, and the bamboo shoot heads are broken into 3mm-6mm fragments with a crusher, and the bamboo shoot heads are crushed with a stainless steel press. Juicing is carried out, and the bamboo juice and bamboo shoot residue are separated after squeezing;

[0009] Put the bamboo juice squeezed from the juicer into the enzymatic hydrolysis tank, gradually increase the temperature of the enzymatic hydrolysis tank to 80°C-95°C, and when the temperature drops to 55°C-60°C, add 10mg of bamboo juice to the bamboo juice / L~500mg / L of pectinase, the enzymatic hydrolysis time is 120min~600min, and the stirrer is turned on during the enzymolysis process to stir slowly;

[0010] The bamboo juice after enzymolysis is filtered by membrane, and microfiltration is carried out at a pressure of 0.10Mpa to 2Mpa and a flow rate ...

Abstract

The invention discloses a method for extracting bamboo juice from bamboo shoot leftovers, which comprises the following steps of: removing soil from aged bamboo shoots which are cut in bamboo shoot processing, and stripping bamboo shells; cleaning, squeezing and separating out the bamboo juice and bamboo shoot dregs; and extracting clear bamboo juice through enzymolysis and a membrane separation technology. The bamboo juice extracted from the bamboo shoot leftovers has richer nutrition, sweet taste and low cost and saves fuel compared with that extracted from bamboo, forest resources can be reasonably utilized, the green homeland of people is protected, waste is reduced, environment is protected, and the method has good social and economic benefits.

Description

technical field [0001] The invention relates to the extraction of raw food juice, in particular to a method for extracting bamboo juice from bamboo shoots leftover from bamboo shoots, and belongs to the technical field of food processing. Background technique [0002] Bamboo shoots are an important food resource with high nutrition. Fresh bamboo shoots contain 90% water, 4% fiber, 3% protein, 2.5% total sugar, and about 0.5% fat. They are rich in various trace elements, and all parts of bamboo shoots contain A variety of nutrients, including potassium content as high as 4%, protein 2.6%, amino acid 0.69%, these are rare in general plant foods. [0003] Bamboo shoot processing needs to cut off the lower 1 / 3 of the aged bamboo shoot head before processing dried bamboo shoots or canned bamboo shoots. Thousands of tons of bamboo shoot leftovers contain very nutritious cellulose, protein, fat and polysaccharides, and the effective utilization rate of bamboo shoots is only 30%. ...
