Organic acid salt compound acidifying agent for aquatic products and preparing method of acidifying agent

Abstract

The invention is applicable to the technical field of feed additives, and provides an organic acid salt compound acidifying agent for aquatic products and a preparing method of the acidifying agent. The acidifying agent is prepared from, by weight, 30-45 parts of formic acid, 15-35 parts of acetic acid, 10-20 parts of propionic acid, 28-32 parts of lactic acid, 1-4 parts of citric acid, 3-10 partsof an acidity regulator, 0.2-1.4 parts of a mouthfeel corrigent, 10-25 parts of purified water, 0.04-6 parts of metal salt and 12-22 parts of a surfactant. The invention further provides the preparing method of the acidifying agent. In this way, underground water or domestic drinking water is adopted as a diluent for the acidifying agent, after the acidifying agent is diluted by 1,000 times, thepH value is 3.6-4.2, microorganisms in feed can be effectively removed, the intestinal health of the aquatic animals is improved, the growth performance of the aquatic animals is improved, and the aquaculture production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to an organic acid salt compound acidifier for aquatic products and a preparation method thereof. Background technique [0002] Acidifier is a feed additive with broad-spectrum and high-efficiency antibacterial activity, low toxicity, and no residue. Adding it to aquatic animal feed can increase the acidity of the feed, improve the digestive tract environment of aquatic animals, and meet the nutritional needs of aquatic animals. And can prevent diseases; the acidifiers in the prior art generally focus on improving the antibacterial properties and growth-promoting properties of the acidulant, but there are few studies on the buffering capacity of the acidulant. [0003] CN106359895A discloses a mixed feed additive liquid acidity regulator and a preparation method thereof. The acidity regulator is made of the following components in parts by weight: 30-50 parts by weight of for...

Problems solved by technology

[0004] Although the acidulant has a high buffer capacity and can effectively avoid excessive fluctuations in the acidity of the gastrointestinal tract of animals, the water used for dilution is the third-grade water specified in GB / T 6682-2008. The water obtained by distillation or ion exchange has a pH range of 5.0 to 7.5 and an oxidizable substance content of ≤0.4. However, in the actual production process, it is time-consuming and costly for farms to use tertiary water; if direct use of farms If the tap water or ground water or drinking water is diluted 1000 times, the pH value of the acidifier disclosed in CN106359895A is already greater than 4.5, the buffer capacity will be insufficient, the cost of use will increase, and the cost performance is low

[0005] In addition, because the breeding of aquatic animals is inseparable from the water system, all their life activities are completed in the water, and the water system is connected with nature, and harmful substances such as ammonia nitrogen and nitrite nitrogen are easy to accumulate in large quantities, and changing water in the breeding pond is also easy to change the external environment. The pathogenic bacteria in the water are brought into the water body, which increases the risk of aquatic animal disease outbreaks and brings economic losses to the breeding enterprises

[0006] In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve
