Description
Technical Field
The invention relates to the technical field of feeds, and particularly relates to a method for preparing a high-dietary-fiber fermented feed by using pineapple peel residues and application of the high-dietary-fiber fermented feed.
Technical Field
China is one of ten major countries of pineapples, the pineapple yield of China reaches millions of tons every year, the pineapple pomace accounts for 50-60% of the whole pineapple, but the utilization amount of the pineapple peel pomace generated after the pineapples are processed is extremely limited, the pineapple peel pomace is not used as an animal auxiliary feed or used for extracting bromelain and pectin, and is not used as a waste material but used in a high-valued manner, so that resources are wasted, and serious environmental pollution is caused. The pineapple peel residue has high nutritive value and good palatability, is popular among cattle, sheep and pigs, has higher feeding value and unique pharmaceutical function of bromelain, and is the best raw material of animal feed. However, because the pineapple dregs are easy to go bad and rot, the problems that the safety of the meat milk product is influenced by directly feeding residual ripener, pesticide and the like on the peels without treatment and the like are solved, and the use of the pineapple dregs is limited. Therefore, if the corresponding technology is adopted for reasonable processing, the maximum utilization of resource utilization can be realized, and the feeding value of the feed is improved.
The dietary fiber is a high molecular polysaccharide which is difficult to digest by digestive enzymes of human bodies, and has various generally accepted physiological functions, for example, the dietary fiber diet can solve some problems of piglet diarrhea, sow constipation and the like. At present, the development and application of food dietary fibers (beet fibers, wheat bran, corn bran, oat fibers, soybean residue fibers and the like) in China are wide, but the research and development of fruit dietary fibers are relatively few, and the fruit dietary fibers comprise pineapple peel residues. The pineapple peel residue is rich in dietary fiber, rich in sugar and vitamins and good in water retention and fermentability. If the pineapple peel residue is fermented by the microbial fermentation technology to produce high-quality dietary fiber products and the like, the nutritional value and the feeding value of the pineapple peel residue can be improved, and the effects of energy conservation and emission reduction are achieved.
At present, experts at home and abroad have carried out certain research on the development and utilization of pineapple pomace, and the silage for cattle and sheep is mainly prepared by a silage technology, and protein feed, probiotic preparation, active dry yeast or other biological feed and the like for single stomach and ruminant are prepared by a fermentation technology. The prior art has the problems of complex fermentation process, high energy consumption and processing cost, loss of beneficial nutritional ingredients in the processing process or unstable product quality and the like, and the research on preparing the pineapple dietary fiber by the fermentation technology is relatively less. In the research aspect of preparing dietary fiber from pineapple peel residues, the publication number is CN102246966A, namely the patent application of 'preparation method of pineapple dietary fiber', the dietary fiber is prepared from pineapple residues serving as raw materials by the working procedures of alkali treatment, alkali washing, pulping to remove black spots, acid regulation, filter pressing, sterilization and the like. The patent application utilizes pineapple dregs for processing, the adopted process is more basic, and a microbial fermentation technology is not adopted, so that the obtained product is more primary. Therefore, a large digging space exists for the development and utilization of the pineapple peel residues. If the high-quality dietary fiber products and the like are prepared by fermenting the pineapple peel residues by using the microbial fermentation technology, the aims of improving the product quality, reducing the product cost, protecting the environment and turning waste into wealth can be fulfilled.
Disclosure of Invention
In order to solve the problems, the invention provides a method for preparing high dietary fiber fermented feed by using pineapple peel residues and application thereof. The research aims to provide a comprehensive utilization method of pineapple peel residues through a microbial anaerobic fermentation technology, and aims to solve the limitation of industrial utilization of the pineapple peel residues in the prior art, fully convert the pineapple peel residues into usable substances, improve the feeding value of the pineapple peel residues and avoid pollution of waste pineapple peels to the environment.
The method for preparing the high dietary fiber fermented feed by using the pineapple peel residues, provided by the invention, comprises the steps of 83.75-91.74 parts of the pineapple peel residues, 7.80-15.97 parts of a microbial leavening agent and 0-0.46 part of a pH value regulator sodium carbonate, and performing anaerobic fermentation to obtain the high dietary fiber fermented feed; the microbial starter comprises the following components: 0.07-7.34 parts of lactobacillus acidophilus, 0.0004-0.05 part of saccharomyces cerevisiae, 0-7.33 parts of molasses, 0-1.69 parts of urea and 0.42-0.84 part of calcium carbonate.
The method for preparing the high dietary fiber fermented feed by using the pineapple peel residues comprises the following steps:
1) activating lactobacillus acidophilus, performing amplification culture for 19-21h to obtain lactobacillus acidophilus liquid, mixing lactobacillus acidophilus liquid and saccharomyces cerevisiae powder in proportion to obtain composite microbial liquid, and adding molasses, urea and calcium carbonate into the composite microbial liquid in proportion to be mixed uniformly to obtain a microbial starter for later use;
2) pulping the pineapple peel residue at 4-10 ℃ overnight to obtain pineapple peel residue pulp, inoculating the microbial starter into the pineapple peel residue pulp, uniformly mixing, adding sodium carbonate to adjust the pH to 5.48-6.48 to obtain the pineapple peel residue pulp to be fermented, and placing the pineapple peel residue pulp in an environment at 25-30 ℃;
3) squeezing out the water in the pineapple peel residue pulp to be fermented by using a filter press to obtain pineapple peel juice to be fermented and pineapple peel residue to be fermented, wherein the water content of the pineapple peel residue juice to be fermented is 70-75%;
4) filling the pineapple residue juice to be fermented into a fermentation barrel, sealing and fermenting, 25-40 kg-
Barrel, standing and fermenting for 2-5 days at 30-35 ℃ to obtain fermented pineapple dreg juice;
5) and (3) putting the pineapple peel residues to be fermented into a fermentation breather bag with a breather hole for fermentation, wherein the fermentation breather bag is 20-30 kg/bag, and standing and fermenting at the temperature of 30-35 ℃ for 2-5 days to obtain the fermented pineapple peel residues.
Further, the fermentation in the steps 4) and 5) is anaerobic fermentation.
