Problems solved by technology

[0005] The existing preparation methods of acidifiers are mainly simple physical mixing and granulation. This preparation method is often costly, difficult to preserve, highly corrosive, and adding high doses will reduce the palatability of feed or lead to loss of vitamins.
In the existing patent literature, the process of preparing acidulant by microbial fermentation is generally complex, generally including multi-step fermentation or multiple fermentations, long fermentation time and high cost

Embodiment 1

[0040] 1. Fruit and vegetable waste treatment: Fruit and vegetable waste is taken from farmers’ markets and orchards. The main raw materials are seasonal fruits and vegetables. The raw materials used in this example are partially rotten and unsuitable for sale from the orchard. After sorting and removing a large area of ​​rot and cutting out a small part of rotten parts, cut them into small pieces with a thickness of about 0.5 cm, weigh them and place them in a fermentation container.

[0041] 2. Juicing: add 8% sucrose by mass, let stand for 8 hours to produce juice.

[0042] 3. Preparation of starter: the fermentation bacteria are commercially available saccharomyces, bacteria powder of Acetobacter and lactic acid bacteria, and the lactic acid bacteria in this embodiment are Lactobacillus plantarum. The starter is inoculated twice. First, mix the yeast and Lactobacillus plantarum before inoculating, and stir slightly; then, splash and inoculate the Acetobacter on the surface...

Embodiment 2

[0049] 1. Fruit and vegetable waste treatment: The raw materials used in this example are partially rotten fruits from the farmer’s market and vegetables that have been placed for more than 2 days, including apples, pears, oranges, grapes, dragon fruits, Chinese cabbage, Chinese cabbage, For lettuce, lettuce, etc., after sorting and removing some rotten parts, the fruit is cut into small pieces with a thickness of about 0.5 cm, and the vegetables are cut into small pieces with a length of about 0.5 cm. After weighing, place them in a fermentation container.

[0050] 2. Juicing: add 12% sucrose by mass, let stand for 16 hours to produce juice.

[0051] 3. Preparation of starter: the fermentation bacteria are commercially available yeast, bacteria powder of Acetobacter and lactic acid bacteria, and the lactic acid bacteria used in this example is Lactobacillus fermentum. The starter is inoculated twice. First, mix the yeast and Lactobacillus acidophilus before inoculating, and s...

Embodiment 3

[0058] 1. Fruit and vegetable waste treatment: Fruit and vegetable waste is taken from farmers’ markets and orchards. The main raw materials are seasonal fruits and vegetables. The raw materials used in this example are lychees that are partially rotten from the orchard and unsuitable for sale after being placed for more than 3 days After sorting and removing large areas of rotten lychees, squeeze the lychees to break the shells, weigh them and place them in a fermentation container.

[0059] 2. Juicing: add 10% sucrose by mass, let stand for 10 hours to produce juice.

[0060] 3. Preparation of starter: the fermentation bacteria are commercially available yeast, bacteria powder of Acetobacter and lactic acid bacteria, and the lactic acid bacteria used in this example is Lactobacillus fermentum. The starter is inoculated twice. First, mix the yeast and Lactobacillus casei before inoculating, and stir gently; then, splash and inoculate the Acetobacter on the surface of the ferm...

Abstract

The invention provides an acidifying agent as well as a compound bacterium one-step fermentation preparation method and application thereof. According to the compound bacterium one-step fermentation preparation method, fruit and vegetable wastes are used as fermentation raw materials and are subjected to one-step-method surface layer air-blowing fermentation through compound bacteria of saccharomycetes, lactic acid bacterium and acetobacter aceti to prepare the acidifying agent. According to the method provided by the invention, nutrient components in the fermentation raw material can be efficiently utilized, types and content of organic acids in a fermentation solution are effectively improved, the fermentation time is shortened, the pH (Potential of Hydrogen) value is reduced, a fermentation technology is simple and the cost is low. The acidifying agent prepared by the method has the advantages that the types of the organic acid are more and the content is moderate, the pH value is lower and the content of alcohol is relatively low; the acidifying agent can be directly used as a feed additive or is subjected to dreg removal and concentration to be used as the feed additive, and is mixed with feed to feed animals; the acidifying agent has good palatability and a high digestion rate; the feed intake and the daily weight gain of the animals are easy to improve and the diarrhea rate is reduced; the acidifying agent has a good application prospect.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to an acidifier, a preparation method and application of one-step fermentation of the compound bacteria. Background technique [0002] Acidifiers can effectively improve the digestive tract adaptability and intestinal health of animals. As a substitute for antibiotics, they have been widely used in poultry feed, piglet feed and other feeds, and become a natural health-care feed additive with high efficiency, no pollution and no residue. . [0003] The mechanism of action of feed acidifier mainly includes reducing the pH value of the feed, reducing the pH value in the stomach, increasing the activity of digestive enzymes; slowing down the speed of gastric emptying, promoting digestion; improving the microbial flora of the gastrointestinal tract, and exerting antibacterial and bactericidal effects ; Promote the absorption of minerals and vitamins; directly participate in ene...
