Pollen wall breaking process

Abstract

The invention discloses a pollen wall-breaking process. The process comprises the following steps: 1, taking a set amount of pollen, and mixing with water; 2, freezing the pollen liquid mixed in the step 1; 3, performing microwave treatment on the frozen pollen pulp obtained in the step 2; 4, adding a compound enzyme into the pollen pulp subjected to microwave treatment in the step 3 for enzymolysis, and then carrying out sufficient enzymolysis according to set time; and 5, concentrating and drying the pollen subjected to sufficient enzymolysis. The invention has the following advantages: (1) the equipment investment cost is low, the popularization and application are easy, and the equipment only needs a refrigerator, a freezer, microwave equipment and a water bath kettle; (2) the wall breaking temperature is low, and the loss of nutritional ingredients is reduced; and (3) due to microwave treatment, a sterilization effect is achieved, and the risk of food damage is reduced in the subsequent processing of pollen food and (4) the processing amount of the pollen can be adjusted as required and (5) the pollen wall-breaking process is relatively simple and easy to operate.

Description

technical field [0001] The invention relates to the field of pollen deep processing, in particular to a pollen wall breaking process. Background technique [0002] Pollen is rich in amino acids, proteins, sugars, trace elements and biologically active substances, such as enzymes, flavonoids, nucleic acids, organic acids, etc. It is highly nutritious and natural. It is favored by consumers. Pollen is a precious natural food, but there is a very hard outer wall on the surface of pollen, which is composed of sporopollenin, cellulose, etc. It is resistant to acid, alkali, pressure, temperature, and is very stable to digestive enzymes, so The bioavailability of pollen is very low. In order to improve the utilization value of pollen, it is first necessary to break the pollen wall. [0003] The pollen wall-breaking method that adopts in the prior art is usually the following several: one, the mechanical wall-breaking based on the action of mechanical force, such as the superfine...

AI Technical Summary

Problems solved by technology

[0003] The pollen wall-breaking method that adopts in the prior art is usually the following several: one, the mechanical wall-breaking based on the action of mechanical force, such as the superfine crushing wall-breaking method, adopts jet milling and planetary milling to pulverize the pollen; The wall method requires expensive equipment, and the amount of pollen input is relatively fixed and cannot be adjusted flexibly;

[0004] 2. Ultrasonic wall-breaking method: the pollen liquid is placed in an ultrasonic generator for ultrasonic treatment; although the wall-breaking method has mild conditions, the degree of wall-breaking is low;

[0005] 3. Enzyme method: Add cellulase to the pollen liquid and hydrolyze it at 40-50°C for about 12 hours; since cellulase and pectinase are usually used to degrade plant cell walls, they have little effect on the pollen wall, and more enzymes are required . Enzymatic degradation often uses a higher temperature and takes longer than 10 hours, which often leads to the proliferation of microorganisms in the pollen and causes the quality of the pollen to decline;

[0007] 5. Temperature difference wall breaking method: use liquid nitrogen with a temperature of about minus 195°C as a cold source to freeze corn pollen, and thaw: use boiling water at about 96°C to thaw the frozen corn pollen quickly in a short time, reaching The purpose of breaking the wall; the whole process equipment investment is high, which is not conducive to promotion
