Method for improving yield of nata de coco

Abstract

The invention relates to a method for improving the yield of nata de coco. The method comprises the following steps of: mixing naturally fermented coconut water and water, adding sucrose to regulate the Brix sugar degree, regulating the pH value to 3.6-4.0 to form a fermentation solution, and adding (NH4)2SO4, KH2PO4, MgSO4, Vc, UDP-Glucose and Na2SO3 into the fermentation solution; and inoculating 5 percent of gluconacetobacter xylinus culture mother solution to the fermentation solution, standing, culturing for 4 to 6 days, and thus harvesting the nata de coco. The method is simple in process and convenient to operate; by adding the Vc, the UDP-Glucose and the Na2SO3 into the fermentation solution, the antioxidant activity in the fermentation solution can be improved, the oxidative stress of bacterial cells is reduced, the cellulose synthesizing capability of the bacterial cells is effectively improved, and many problems of insufficient raw material supply, low yield of the nata de coco, poor recycling effect of the fermentation solution and the like in production practice are effectively solved; and the method has important economic benefits and social benefits for sustainable development of the nata de coco industry.

Description

technical field [0001] The present invention relates to a kind of coconut fine fruit production method, specifically relate to a kind of by adding appropriate amount of V C Compositions such as the method for improving coconut fine fruit output. Background technique [0002] Coconut fiber fruit (Nata de coco) is an edible fiber gel thick film grown on the surface of the culture medium through bacterial fermentation with coconut water or coconut juice as raw material. Its main component is a unique gelatinous property of bacterial cellulose. Compared with plant cellulose, bacterial cellulose has the characteristics of high water holding capacity, high tensile strength, and high biological adaptability, and has been widely used as a new type of biomaterial in food, medicine, papermaking, acoustic materials and other fields. Because coconut fibrous fruit is rich in cellulose, has high water holding capacity, good elasticity, smooth taste and good chewiness, it has health func...
