Problems solved by technology

[0006] However, due to the inherent anti-degradation barrier structure of the cell membrane and cell wall of microorganisms and plants and the anti-nutritional factors (hemicellulose, phytic acid, acid-soluble lignin, etc.) Therefore, there is an urgent need to develop a production process that uses microorganisms and plants as raw materials to produce high-digestibility nutrient-enhanced feed additives.

Embodiment 1

[0033] Preparation of DHA Nutritional Enhanced Feed Additive

[0034] It mainly includes: mix the non-mildew and complete linseed with 0.5% iron-free calcium chloride aqueous solution at a mass ratio of 1:6, adjust the pH value of the mixed material to 4, and pour it into a high-pressure hydrothermal reaction kettle , Cover the lid of the reaction kettle, connect the vacuum pump through the gas outlet above the liquid level, and vacuum for 5 minutes to remove oxygen. Then close the outlets of the reactor, heat to 100°C, open the outlet of the reactor to deflate for 30 seconds, and then start the hydrothermal pretreatment. The hydrothermal pretreatment conditions are: temperature 100°C, treatment time 60 minutes, stirring speed 60 rpm, initial pH value 7. After the treatment is completed, quickly deflate and cool down to 90°C, and after solid-liquid separation, wash the linseed with deionized water once. The schizontium algae powder and the pretreated flaxseed were mixed in a...

[0036] Preparation of ARA Nutritional Enhanced Feed Additive

[0037] It mainly includes: mixing evenly the mildew-free and complete evening primrose seeds with 1% iron-free calcium chloride aqueous solution at a mass ratio of 1:10, adjusting the pH value of the mixed material to 5 and pouring it into high-pressure hydrothermal reaction In the kettle, cover the lid of the reaction kettle, connect the vacuum pump through the gas outlet above the liquid level, and vacuumize for 5 minutes to remove oxygen. Then close the outlets of the reactor, heat to 100°C, open the outlet of the reactor to deflate for 30 seconds, and then start the hydrothermal pretreatment. The hydrothermal pretreatment conditions are temperature of 120°C, treatment time of 30 minutes, stirring speed of 150 rpm, and initial pH value of 7. After the treatment, quickly deflate and cool down to 90°C. After solid-liquid separation, wash the evening primrose seeds with water once. Mortierella alpina thalline and...

[0039] Preparation of γ-Linolenic Acid-Squalene-DHA Nutritional Enhancement Feed Additive

[0040] It mainly includes: mixing the mildew-free and complete perilla seeds with 0.8% iron-free calcium chloride aqueous solution at a mass ratio of 1:10, adjusting the pH value of the mixed material to 5 and pouring it into high-pressure hydrothermal reaction In the kettle, cover the lid of the reaction kettle, connect the vacuum pump through the gas outlet above the liquid level, and vacuumize for 5 minutes to remove oxygen. Then close the outlets of the reactor, heat to 100°C, open the outlet of the reactor to deflate for 30 seconds, and then start the hydrothermal pretreatment. The hydrothermal pretreatment conditions were as follows: a temperature of 150° C., a treatment time of 10 minutes, a stirring speed of 150 rpm, and an initial pH value of 7. After the treatment, the temperature is quickly released to 90°C, and after solid-liquid separation, the perilla seeds are washed onc...

Abstract

The invention relates to a nutrient strengthened feed additive as well as a preparation technology and application thereof. The preparation technology mainly comprises the following steps of (1) pretreating materials: uniformly mixing nutrient-enriched plant biomass to be treated, with a 0.1-1% ferrum-free calcium chloride aqueous solution; (2) pretreating the nutrient-enriched plant biomass through an oxygen-free calcium salt hydrothermal method so as to obtain solid hydrothermal plant biomass; (3) mixing the solid hydrothermal plant biomass with nutrient-enriched microorganism thalli to obtain a mixture, pouring the mixture in a colloid mill, and performing treatment so as to obtain colloid mill treatment fluid; (4) adding an antioxidant to the colloid mill treatment fluid; and (5) homogenizing and emulsifying the oxidation resistant-colloid mill treatment fluid with a high pressure homogenizer. The nutrient strengthened feed additive prepared by the preparation technology disclosedby the invention forcefully protects nutrient components in plant seeds, has the advantages of being high in digestibility, good in absorptivity, high in nutrient conversion rate and high in deposition rate, can notably increase the content of specific nutrients in livestock and poultry products, and can be used as a feed additive for livestock and poultry, aquaculture animals and companion animals.

Description

technical field [0001] The invention relates to a nutrient-enhanced feed additive, in particular to a feed additive for producing nutritionally-enhanced functional food, as well as its preparation process and application. Background technique [0002] Food contains a variety of nutrients, but because of different types, their distribution and content are not the same. In addition, nutrients are often lost during food production, processing and storage. Nutritionally fortified food refers to food that has added natural or artificially synthesized natural nutrients to enhance its nutritional content. Nutritionally fortified food can not only supplement the lack of nutrients in food, improve the nutritional value of food, meet the needs of different groups of people, but also simplify dietary treatment, facilitate food intake, and prevent disease and health care. [0003] Existing studies have shown that polyunsaturated fatty acid nutrients (including docosahexaenoic acid, ei...
