Embodiment 1

[0023] (1) Add deionized water to the pollen and mix evenly so that the moisture content of the pollen is 10% by weight; and freeze at minus 20° C. for 24 hours to obtain ice-crystallized pollen.

[0024] (2) Put 2 kg of ice-crystallized pollen into 18 liters of pollen extract at a temperature of 95°C, and the temperature of the pollen extract with ice-crystallized pollen dropped to about 75°C; the pollen extract contains 10 volumes % of ethanol, 0.24% by weight of alkali metal dihydrogen phosphate (sodium dihydrogen phosphate), 0.03% by weight of alkali metal monohydrogen phosphate (disodium hydrogen phosphate), 0.05% by weight of alkali metal hydroxide (hydroxide sodium) and 0.02% by volume of Tween (Tween-80) in water.

[0025] Introduce the pollen extract (volume of about 20 liters) into a centrifugal homogenizer (purchased from IKA model T-18 high-speed shear emulsifier) ​​for centrifugal homogenization; shear rate It is 12000rpm, and the time is 5 minutes.

Abstract

The invention provides a pollen processing method which comprises the following steps: (1) adjusting pollen moisture content to 8 to 12 weight%, freezing to-10 DEG C and maintaining for 20-52 hours to ice crystallized pollen; (2) pouring the ice crystallized pollen into a pollen extraction liquid at the temperature above 90 DEG C to rise the ice crystallized pollen temperature to more than 65 DEG C in 5 seconds, and in turn centrifugally homogenizing and homogenizing under high pressure to get wall-broken pollen pulp; and (3) centrifuging the wall-broken pollen pulp to obtain supernatant and pollen mud; wherein the pollen extraction liquid is an aqueous solution containing 8 to 12 vol% of ethanol, the pollen extraction liquid also contains 0.2 to 0.3 weight% of alkali metal dihydric phosphate, 0.02 to 0.04 weight% of alkali metal phosphate hydride, 0.04 to 0.06 weight% of alkali metal hydroxide and 0.01-0.03 vol.% of Twain. The pollen processing method is high in pollen wall broking rate and nutrient composition extraction efficiency.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for processing pollen. Background technique [0002] Pollen is rich in nutrients and contains all the nutrients for plant growth. It is called a natural nutritional and healthy food. Generally, the protein content of pollen is 7% to 35%, the fat content is 5% to 10%, and the carbohydrate content is 40% to 50%. Minerals 2% to 3%, lignin 10% to 15%, unknown substances 10% to 15%. Among them, the essential amino acid content in rapeseed pollen accounts for about 40% of the total amino acid, and the content of lysine and leucine both reach more than 8%. The average content of lipids in pollen is 9.2%, of which unsaturated fatty acids account for 60% to 91%, which is much higher than that in other animal and vegetable oils. In addition, the phytosterols in pollen mainly include ergosterol, stigmasterol, sitosterol, Campesterol, the highest sterol content in rapeseed pollen. ...
