Sugar stevia leaf waste residue fermented feed and preparation method thereof

Abstract

The invention relates to the technical field of feeds, and provides a sugar stevia leaf waste residue fermented feed. According to the sugar stevia leaf waste residue fermented feed, based on the weight of sugar stevia leaf residues being 100%, the sugar stevia leaf waste residue fermented feed comprises 100% of the sugar stevia leaf residues, 1% of cane sugar, 0.1%-0.5% of lactic acid bacteria, 0.01-0.02% of xylanase, 0.004-0.01% of cellulase, 0.004-0.01% of mannase, 0.002-0.005% of pectinase and 36-48% of water. A preparation method of the sugar stevia leaf waste residue fermented feed comprises the steps of dissolving brown sugar in water, adding the lactic acid bacteria, performing sufficient and uniform stirring, then performing standing for 30min, after strains are activated, addingthe cellulase and the xylanase, and performing thorough and uniform mixing to obtain a mixture; and uniformly mixing the mixture with the sugar stevia leaf residues to form a fermentation substance ofwhich the water content is 35-40%, and performing fermentation for 72-96h, wherein after the fermentation substance generates sour and sweet taste, fermentation is completed. The sugar stevia leaf residues generated by production of the steviol glycoside are used as main raw materials to prepare the fermented feed, so that the value of the sugar stevia leaf waste residues can be increased, the environmental pressure can be alleviated, and besides, the fermented feed contains massive beneficial bacteria, has a good health-care effect on livestock and poultry animals, and can reduce the use ofantibiotics, the meat quality of the livestock and poultry is improved, and the breeding cost is reduced.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a stevia waste residue fermented feed and a preparation method thereof. Background technique [0002] The main component of stevia rebaudiana leaves is steviol glycoside, its sweetness is about 300 times that of sucrose, and its heat energy is only 1 / 300 of that of sucrose. Part of sucrose is widely used in food, beverage, table condiment, and pickle processing, and is known as the most promising new sugar source. As the market's demand for stevia sugar continues to grow, a large amount of stevia waste residue will also be produced. [0003] As the largest production base of steviol glycosides in my country, Ganzhou currently produces more than 70,000 tons of stevia waste residue every year. The poor treatment of so many waste residues will bring great pressure to the surrounding environment. At present, stevia waste residues are mainly used as fertilizers and returned to the fiel...

Problems solved by technology

The poor treatment of so many waste residues will bring great pressure to the surrounding environment. At present, stevia waste residues are mainly used as fertilizers and returned to the field. Some companies are also trying to use stevia waste residues for bio-power generation. It is still limited, and the nutrients and active substances in it have not been rationally utilized
