Abstract

The invention provides a method for using pineapple peel and slag to prepare high activity dried yeast and ferment feed. The technique has the implementing steps of: crushing pineapple peel, extruding juice, separating pineapple peel juice and slag, adding the substances of molasses, ammonium sulfate and the like into pineapple peel juice, adding saccharomyces cerevisiae or candida utilis strain for liquid fermentation, carrying out separation on the yeast thallus after the fermentation is completed, drying under low temperature and obtaining active dried yeast which can be used as additives of food or feed. In addition, aspergillus niger, aspergillus oryzae, lactobacillus plantarum and complex enzyme are added into the separated pineapple slag for fermentation, and the fermented products are used as feed which is directly fed or dried, thus being capable of reducing feed cost. The invention not only solves the environmental pollution of processing waste, changes waste into valuables, and expands the space of the feed materials and feed additives.

Example Embodiment

[0016] Embodiment one:

[0017] Crush the pineapple peel first, then squeeze out the juice, and separate the pineapple peel juice and pineapple residue. Calculated by weight percentage, add 0.5 part of molasses and 0.1 part of ammonium sulfate to every part of pineapple peel juice, boil and sterilize, and then add 0.5 part of Saccharomyces cerevisiae or Candida spp. to carry out liquid fermentation after cooling to 28°C. The parameters controlled after inoculation are: temperature 28°C, dissolved oxygen 100%, ventilation ratio 1:1, tank pressure 0.05Mpa, rotation speed 300. After the fermentation is completed, the yeast cells are centrifuged and dried at low temperature to obtain active dry yeast, which can be used as a food or feed additive.

[0018] Simultaneously, calculate by weight percentage, add 30 parts of corn flour, 0.5 part of ammonium sulfate, 0.2 part of sodium carbonate, 0.5 part of Aspergillus niger, 0.1 part of Aspergillus oryzae, 0.1 part of Lactobacillus plantarum and 0.2 part of Parts of complex enzymes are used for solid fermentation, the fermentation temperature is controlled to be 30° C., and the fermentation time is 60 hours. After the fermentation material is sour and fragrant, the fermented product is used as feed for direct feeding to animals.

Example Embodiment

[0019] Embodiment two:

[0020] Crush the pineapple peel first (the slag does not need to be crushed), squeeze out the juice, and separate the pineapple peel juice and pineapple residue. Calculated by weight percentage, add 2 parts of molasses and 1 part of ammonium sulfate to 1 part of pineapple peel juice, boil and sterilize, and when it is cooled to 29 ° C, add 0.8 parts of Saccharomyces cerevisiae or Candida albicans for liquid fermentation , the parameters controlled after inoculation are: temperature is 30°C, dissolved oxygen is 100%, aeration ratio is 1:1 (10 liters of tank ventilation is 10 liters), tank pressure is 0.05Mpa, and rotating speed is 300. After the fermentation is completed, the yeast cells are centrifuged and dried at low temperature to obtain active dry yeast, which can contain 15 billion live cells per gram. It is a high value-added product and can be used as a food or feed additive.

[0021] Simultaneously, calculate by weight percentage, add 40 parts of corn flour, 1 part of ammonium sulfate, 0.4 part of sodium carbonate, 0.8 part of Aspergillus niger, 0.3 part of Aspergillus oryzae, 0.4 part of Lactobacillus plantarum and 1 part of The compound enzyme is used for solid fermentation, wherein the compound enzyme contains cellulase, pectinase, and phytase. The fermentation temperature is controlled at 42°C, and the fermentation time is 65 hours. After the fermentation material is sour and fragrant, the fermentation is stopped. The product is directly fed or dried as feed, which can reduce the cost of feeding.

Example Embodiment

[0022] Embodiment three:

[0023] Crush the pineapple peel first, then squeeze out the juice, and separate the pineapple peel juice and pineapple residue. Calculated by weight percentage, add 3 parts of molasses and 2 parts of ammonium sulfate to every 1 part of pineapple peel juice, boil and sterilize, and then add 1 part of Saccharomyces cerevisiae or Candida spp. to carry out liquid fermentation after cooling to 30°C. The parameters controlled after inoculation are: temperature 35°C, dissolved oxygen 100%, ventilation ratio 1:1, tank pressure 0.05Mpa, rotation speed 300. After the fermentation is completed, the yeast cells are centrifuged and dried at low temperature to obtain active dry yeast, which can be used as a food or feed additive.

[0024] Simultaneously, calculate by weight percent, add 50 parts of corn flour, 2 parts of ammonium sulfate, 0.5 part of sodium carbonate, 1 part of Aspergillus niger, 0.5 part of Aspergillus oryzae, 0.5 part of plantaractobacillus and 2 parts Parts of compound enzymes are used for solid fermentation, the fermentation temperature is controlled to be 45° C., and the fermentation time is 72 hours. After the fermentation material is sour and fragrant, the fermented product is used as feed for directly feeding animals.

[0025] The invention utilizes pineapple peel and slag to produce active dry yeast, and uses compound enzymes to degrade the pineapple peel and slag. After the pineapple peel and slag are processed, the final product includes active dry yeast and enzymatic feed at the same time. It avoids the environmental pollution of processing waste, and expands the space of feed raw materials and feed additives. The source of raw materials is extensive, the production cost is low, and the market prospect is broad.
