A kind of fish paste fermented soybean meal and its production method and application

Abstract

The invention discloses a fish cream fermented soybean pulp and a production method and an application thereof. The method provided by the invention comprises the following steps of (1) preparing soybean pulp, concentrated fish soluble which is subjected to field preservation treatment and contains 50-75wt% of moisture, and pineapple juice which is subjected to field preservation treatment; (2) mixing the raw materials according to the ratio that 200-500kg of concentrated fish cream is used for each ton of soybean pulp, and 100-200kg of pineapple juice is used for each ton of soybean pulp and adding yeast seeds in the mixture; and (3) performing solid fermentation. The product prepared by the method provided by the invention is particularly suitable for the special nutrition demands of young farmed animals, the product is good in palatability, high in digestibility, and the product further has the natural lactation promotion function, thus, the product can improve the milk quality of suckling animals.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a fish paste fermented soybean meal and a production method thereof. Background technique [0002] Fishmeal and pineapple processing plants produce a large amount of waste by-products - fish pulp and pineapple juice, which directly discharges and causes serious environmental pollution, affecting and restricting the sustainable development of the fishmeal and pineapple processing industry. In-depth development of the potential value of these by-products is of great significance to the economic and environmental benefits of the fishmeal and pineapple processing industries. [0003] Fish soluble slurry is a by-product of fishmeal processing. Its main components are water-soluble protein in fish meat and many animal-derived growth-promoting factors. It has very high nutritional value, but it is easy to oxidize, rancid and difficult to preserve. The production practic...

Problems solved by technology

For example, some people use commercial fish paste protein to add to soybean meal. The fish paste protein is a spray-dried product or paste. The cost of spray-drying itself is extremely high, and there is no heat-sensitive biological active substance after spray-drying; The process is cumbersome and requires high fermentation conditions; corresponding to the requirements of different starters for fermentation conditions, this technology uses full sterilization and closed system fermentation (raw materials must be sterilized, fermentation equipment and fermentation process must be carried out in a sterile environment, otherwise easily polluted), the process is complicated and the cost is high

Another example is that someone uses non-concentrated fish paste (water content is generally greater than 92wt%), the active ingredient content is very low, not only difficult to preserve, but also a large amount of addition (in order to ensure that a certain amount of active ingredient is added, the amount of fish paste used per ton of soybean meal is 800-900 kg, resulting in a large water content in the fermentation system, which is extremely unfavorable for fermentation); and due to the high water content of non-concentrated fish paste, pineapple juice can only be added in a small amount (0-60 kg), which basically has no effect; Moreover, the moisture in the fermentation system is high (greater than 50%), and the drying cost is high; the production of compound pure strains is cumbersome and requires high fermentation conditions

[0006] Therefore, due to the above reasons, it cannot be widely used in the field of feed at present.
