Cell wall breaking method of tagetes fresh flower

Abstract

The invention relates to a cell wall breaking method of tagetes fresh flower. The cell wall breaking method comprises the following steps of preparing a compound enzyme preparation, and breaking the cell wall of the fresh flower. The cell wall breaking method is characterized in that 1 to 3 parts of fungal xylanase and 5 to 2 parts of endoglucanase by weight are mixed to form the compound enzyme preparation; the compound enzyme preparation is applied to break the cell wall of the tagetes fresh flower; the usage amount of the compound enzyme preparation is equal to 0.005 to 0.03% of the usage amount of the fresh flower; the fresh flower is composted and fermented for 3 to 5 days at the environment temperature of 10 to 40 DEG C, so as to reach the cell wall breaking effect of the fresh flower. The cell wall breaking method has the advantages that the cell wall of the fresh flower can be quickly broken by the added enzyme preparation, and can be completely broken in 3 to 5 days, so that the cell wall breaking time is equal to 1/6 to 1/4 of original cell wall breaking time in the prior art; the extracting rate of lutein reaches 97.2%, and is at least increased by 7%; the cell wall breaking time is shortened, the production amount of wastewater is reduced, the production cycle of the product is shortened, and the cost is reduced.

Description

technical field [0001] The invention relates to a cell wall breaking method of marigold flowers. Background technique [0002] Marigold planting, processing, and extraction The processing process of marigold flowers purchased by marigold lutein production enterprises is: fresh flower purchase----green storage fermentation (cell wall breaking)----drying and granulation--- - Lutein extraction. Among them, the green storage fermentation process takes more than 20 days. The principle is to use the biological enzymes produced by lactic acid bacteria during the growth process to dissolve the cell walls of flowers, which is conducive to more complete extraction of lutein. The extraction rate of lutein from flowers without fermentation and wall breaking is about 90%. The problems with this method are: [0003] 1. The fermentation time is more than 20 days, and the fresh flowers cannot be roasted and granulated in time; 2. A large amount of lactic acid wastewater is discharged afte...
