Problems solved by technology

[0006] Post-spraying of liquid vitamins is an effective way to solve the loss of vitamins caused by feed processing, but there are still technical obstacles: vitamins are divided into two categories: water-soluble vitamins and fat-soluble vitamins, and their structures and properties are different, so that all vitamins can be completely dissolved in the solution It is more difficult, and the distribution uniformity of vitamins in the liquid environment is poor; in addition, the simple vitamin solution lacks protective measures; at the same time, the post-spraying of simple vitamins can only be coated on the surface of feed particles, which is easily affected by the environment, transportation and storage. loss of activity

Embodiment 1

[0025] The screening of embodiment 1 compound protective agent and its influence on compound vitamin sedimentation rate

[0026]The raw materials used in the composite protective agent are seaweed powder, sodium alginate, and carrageenan, which are uniformly mixed according to different proportions and then added to the multivitamin. Use the following method to evaluate its performance: water solubility, take 12.5g of composite protective agent, put it in 1000ml water, stir at 100 rpm for 20min to mix, and compare the uniformity of mixing and the difficulty of dissolving in parallel. Viscosity, take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water respectively, stir at 100 rpm for 20min and mix evenly, measure viscosity with NDJ digital display viscometer. Settling rate, start timing 0.5h after stirring evenly, observe the settling speed of the multivitamin solution and the settling rate after 12 hours, the good stability settles slowly and ha...

Embodiment 11

[0030] Mix seaweed powder: sodium alginate: carrageenan evenly according to the weight ratio of 40:15:45 (formulation 1), take 12.5g of compound protective agent and put it in 1000ml water, stir at 100 rpm, the dissolution is slow and the water solubility is poor , after stirring for 20 minutes, there are obvious insoluble matter, which is in the form of agglomerates; take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water, stir at 100 rpm for 20 minutes, and measure the viscosity to be 796mPa.s, the viscosity is too low, and the agglomeration will affect the spraying Atomization effect: After stirring evenly, the multivitamin solution began to settle slowly after 30 minutes, and the settlement rate after 12 hours was 15.3%.

Embodiment 12

[0032] Seaweed powder: sodium alginate: carrageenan is mixed evenly according to the weight ratio of 50:12.5:37.5 (Formulation 2). Take 12.5g of compound protective agent and put it in 1000ml water, stir at 100 rpm, the dissolution is slow, and the water solubility is good. After stirring for 20 minutes, there is a small amount of insoluble matter, which is in the form of small suspended lumps; take 25g of compound protective agent, add 200g of compound vitamins and 2000g of water, stir at 100 rpm for 20 minutes, and measure the viscosity to be 1075mPaf.s. The viscosity is low and does not affect the spray mist After stirring evenly, the multivitamin solution began to settle slowly after 40 minutes, and the settlement rate was 11.5% after 12 hours.

Abstract

The invention relates to the technical field of feed additives, in particular to a special post-sprayed vitamin premix material for aquatic feed. The pH of the vitamin premix material after being dissolved in water is nearly neutral and acidic, a stable environment is provided for various vitamins, and the damage of strong-acid and strong-alkali extreme environments on the vitamins is avoided; and a composite protective agent can enable the vitamin solution to form a stable and uniform solution, an effect for protecting the vitamins sprayed onto the surface of feed can be realized, the dissolve-loss ratio of the vitamins and the loss rate in the transportation process can be effectively reduced, and an unexpected technical effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a post-use vitamin premix for aquatic feed and an application method thereof. Background technique [0002] Vitamins are trace small molecular organic compounds necessary to maintain the normal growth, development and reproduction of animals. Their main functions are to participate in the regulation of material metabolism and energy metabolism as coenzymes, directly participate in physiological activities as physiologically active substances, and act as antioxidants in organisms. Protect the normal structure and physiological functions of cells and organ tissues, and some vitamins are used as structural components of cells and tissues. The nutritional needs of conventional vitamins are an important guarantee for the healthy growth and development of animals, while the nutritional needs of individual vitamins also play a special role in the body's immunity. Vitamin deficie...
