Embodiment 1

[0012] (1) Add deionized water to xanthan gum to make it swell and disperse, and make a wall material solution with a concentration of 2%;

[0013] (2) adding deionized water to the vitamin K salt, heating and dissolving, cooling after mixing, and making a core material solution with a concentration of 0.3%;

[0014] (3) Mix the core material solution with the wall material solution and stir evenly to form a mixed solution. The mass ratio of vitamin K salt to xanthan gum in the mixed solution is 1:20; freeze the mixed solution at -15°C to form an intermediate body;

[0015] (4) Put the intermediate into a freeze dryer and freeze-dry to dryness; the working conditions of the freeze dryer are: the shelf heating temperature is 18°C, and the pressure in the drying box is 2Pa;

[0016] (5) Pulverize the dried intermediate with a pulverizer and pass through an 80-mesh sieve to obtain the product of vitamin K microcapsules.

Abstract

The invention relates to a preparation method of a microcapsule of vitamin K. The vitamin K has the problems of instability and easy metamorphism. In the method, the salt of the vitamin K is used as core material, and xanthan or arabic gum or guar gum or isinglass is used as wall material to prepare the microcapsule of the vitamin K. The detailed preparation method is as follows: the aqueous liquid of the wall material and the aqueous liquid of the core material are respectively prepared; then the two are fully mixed; an the obtained mixture is pre-frozen, frozen, dried, crashed and screened in turn, thus being prepared into the product of the microcapsule of the vitamin K with excellent organoleptic attributes. The product has excellent thermal stability and optical stability, can be used as a food accessory to be applied to food processing to enhance the content of the vitamin K in the food.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a preparation method of vitamin K microcapsules added to food. Background technique [0002] Vitamin K is a kind of nutrient substance necessary to maintain the normal physiological functions of the human body, but vitamin K is active in nature and unstable to light, heat, oxygen, alkaline substances and other factors. Due to the presence of atmospheric humidity, light, metal ions, and acid-base substances, vitamin K will deteriorate and its physiological activity will decrease rapidly. Therefore, the effectiveness of vitamin K will decrease quickly, and the substance after vitamin K deterioration is toxic, which is not conducive to human health. In addition, vitamin K may affect the sensory quality of food after being added to food. Using microcapsule technology and using food glue (ie wall material) to embed vitamin K (ie core material) can not only improve the conten...
