preparation example Construction

[0031] The present invention also relates to a method for preparing the above-mentioned microcapsule fat powder enriched in omega-3 meat, egg and milk, the steps of which are as follows:

[0032] Step 10. Mix starch and water to form a starch slurry, stir and heat to 30-35°C, add sodium hydroxide solution to adjust pH=8.5-9, continue stirring to activate; gradually add octenyl succinic anhydride diluted with ethanol, 1 The addition was completed in ~2 hours, and during the gradual addition process, the pH value of the reaction system was controlled to maintain at 8.2~8.8. After the addition of octenyl succinic anhydride was completed, continue to stir the reaction until the pH was stable at 8.5, and finally added dilute hydrochloric acid to neutralize To pH=6.5, heat up to 90°C to turn into starch paste;

[0033] Step 20. Put oil containing Ω3 into the oil phase tank, heat to 70-80°C, and add compound emulsifier and sodium stearoyl lactylate under stirring, keep warm at 70-80°...

Embodiment 1

[0037] Embodiment 1, the preparation that is rich in omega 3 microcapsule fat powder

[0038] Step 10: Add 20kg of cornstarch and 30kg of drinking water to form a starch slurry, stir and heat to 30-35°C, add sodium hydroxide solution (4%) to adjust the pH to 8.5-9, stir for half an hour, and gradually add octenyl amber Anhydride 0.6kg (diluted with 2.4kg of absolute ethanol or 95% ethanol), added in 1 to 2 hours, during the gradual addition, add sodium hydroxide solution (4%) to keep the pH of the reaction system = 8.2 to 8.8 as the pH decreases ; After adding octenyl succinic anhydride, continue to stir the reaction until the pH is stable at 8.5, and finally add dilute hydrochloric acid (3%) to neutralize to pH = 6.5, and heat up to 90 ° C to become starch paste.

[0039] Step 20: Put 500kg of oil containing Ω3 into the oil phase tank, heat to 70-80°C, add 13kg of compound emulsifier and 5.5kg of sodium stearoyl lactylate under stirring, keep warm at 70-80°C and stir until diss...

Embodiment 2

[0042] Example 2, feeding the fat powder rich in Ω3 microcapsules of the present invention, egg yolk DHA correspondingly increased

[0043] Test group:

[0044] A: Control group (BD: Fujian Hualong Group Longyan company laying hen feed)

[0045] B: Experimental group Ⅰ (BD+0.5% lipogenin)

[0046] C: Experimental group Ⅱ (BD+1% lipogenin)

[0047] Each group of 5 70-week-old Hy-line laying hens was fed continuously for 2 weeks. The results are shown in Table 1 below:

[0048] Table 1

[0049]

[0050] The results showed that: (1) Adding 1% fat powder rich in Ω3 microcapsules to the diet increased the egg weight by 8.8%.

[0051] (2) Adding 0.5% and 1.0% fat powder rich in omega3 microcapsules to the diet increased egg yolk DHA (or C22:6n3) to 32.2% and 59.3%, respectively.

Abstract

The invention provides microcapsule fatty powder capable of increasing content of omega3-enriched meat egg milk and a preparation method of the microcapsule fatty powder. The microcapsule fatty powder capable of increasing the content of the omega3-enriched meat egg milk comprises a water soluble wall material and an omega3-containing fat core material embedded in the wall material, wherein the water soluble wall material is at least one of dextrin, water soluble syrup, whey powder and chitosan, and then is mixed with starch paste, and thus the microcapsule fatty powder is obtained; the omega3-containing fat core material is at least one of linseed oil, deep sea fish oil and algal oil and is prepared by mixing a compound emulsifier with sodium stearoyl lactate. The microcapsule fatty powder capable of increasing the content of the omega3-enriched meat egg milk can be combined at small intestines and pancrelipase easily, the digestion absorption utilization rate of fat containing omega3 is greatly increased, and the fatty powder capable of increasing the content of the omega3-enriched meat egg milk is resistant to oxidation and easy to store and can not be oxidized or become acid, and thus the content of omega3 is guaranteed.

Description

【Technical field】 [0001] The invention relates to a microcapsule fat powder for enhancing the enrichment of omega 3 meat, egg and milk and a preparation method thereof. 【Background technique】 [0002] Polyunsaturated fatty acid (PUFA) refers to a straight-chain fatty acid containing two or more double bonds and a carbon chain length of 18 to 22 carbon atoms. It is the main body and core of research and development of functional fatty acids. Omega-3 polyunsaturated fatty acids include alpha-linolenic acid, EPA, and DHA. Among them, α-linolenic acid is the precursor of EPA and DHA, and its effectiveness in reducing triglycerides, cholesterol, and β-lipoproteins is over 60%. EPA is called "vascular scavenger", it has the effect of dredging and cleaning the heart blood vessels, thus preventing various cardiovascular diseases. DHA, docosahexaenoic acid, commonly known as "brain gold", is a polyunsaturated fatty acid that is very important to the human body, and is an important ...
