Embodiment 1

[0029] a. Preparation of oil phase liquid: Weigh 25kg of DHA and place it in a hot and cold cylinder, keep warm at 45-50°C for 35r / min and stir; then weigh 1.2kg of propylene glycol fatty acid ester and 0.15kg of lecithin according to the formula, and continue to keep warm and stir to prepare oil phase liquid.

[0030] b. Preparation of water phase liquid: Weigh 12kg of soluble rice bran dietary fiber, 40kg of maltodextrin, 802.1kg of Tween and 2kg of compound stabilizer, add 600kg of pure water and put it in another cold and hot cylinder, keep it warm at 50-65℃ for 35r / min stirring to prepare an aqueous phase liquid.

[0031] c. Stirring emulsification: pump the oil phase liquid into the water phase liquid, and add water to adjust the total solid content of the mixed liquid to about 30%, the HLB value is 13.2, keep stirring at 50-60°C for 20 minutes.

[0032] d. High-pressure homogenization: The above-mentioned emulsion is homogenized twice by a valve-type high-pressure hom...

Abstract

The invention discloses a DHA powder grease product rich in dietary fiber. The DHA powder grease product is prepared by following steps: taking soluble rice bran dietary fiber and maltodextrin as wall materials; designing and optimizing a formula; subjecting DHA to double-phase emulsion process, high pressure homogenization, freeze-drying, and the like so as to microencapsulate DHA. The DHA powder grease product is widely used in milk powder, milk tea, solid beverage and other health food so as to increase the nutritional value of the products, improve the organizational structure, exterior quality and palatability of food, prolong shelf life of the products and improve the safety of powder grease products.

Description

technical field [0001] The invention relates to a DHA powder oil with soluble dietary fiber as the wall material and a production method thereof, belonging to the field of food additives. Background technique [0002] Microcapsule technology is a method of embedding solid or liquid with film-forming materials, so as to protect the core material from adverse environmental factors such as temperature, pH, etc., to improve the stability and shelf life of the encapsulated substance, and to expand the encapsulation. A controlled-release technology for pharmaceutical applications. The microcapsule technology is used to coat the unsaturated fatty acid, so as to improve the stability of the oil, so that its nutritional value and flavor can be preserved to the greatest extent, and has broad application prospects. [0003] The selection and ratio of microcapsule wall materials are the key to the successful preparation of microcapsule products. Different wall materials largely determ...
