Embodiment 1

[0049] Select 200g of fresh carrots, wash them with clean water, drain and pulverize them, then dry them in an oven at 40°C for 2 hours, then pulverize the dried carrots with a pulverizer and pass through an 8-mesh sieve.

[0050]Put the quantitative dry raw materials into a 1000 mL flask, add 400 mL of vegetable oil-edible alcohol mixed extract with a volume ratio of 3:7 for extraction, the extraction reagent is food grade, and an ultrasonic extraction device is used, and the extraction temperature is 45 °C. The ultrasonic extraction frequency is 2500MHz, the extraction time is 90min, and then the extract is filtered to remove solid matter. Concentrate the filtrate with a rotary evaporator, recover the solvent, and then dry it in a vacuum freeze dryer to obtain a β-carotene extract.

Abstract

The invention discloses beta-carotene micro-capsule powder and a preparation method thereof. The beta-carotene micro-capsule powder comprises the following components in weight percentage: 3%-6% of beta-carotene, 3%-5% of vitamin C palmitic acid esters, 30%-45% of food-grade gelatin, 15%-30% of starch, 3%-5% of vitamin C sodium, 2%-5% of soybean lecithin and 20%-30% of cane sugar. The preparationmethod comprises the following steps of: extracting the beta-carotene, preparing and mixing an organic-phase solution and a water-phase solution, then carrying out ultrasonic high-speed shearing, high-pressure homogenized emulsification and spraying drying, and the like to finally obtain the beta-carotene micro-capsule powder reaching the nano grade in particle size. The obtained beta-carotene micro-capsule powder has short dissolving time and stability without delamination; in addition, because the food-grade material is fully used as a production reagent and an auxiliary material in a preparation process, the beta-carotene micro-capsule powder accords with the safety standard of food, has the characteristic of simplicity in preparation method and low product cost, and is easy for continuous and automatic production.

Description

technical field [0001] The invention relates to a beta-carotene microcapsule powder and a preparation method thereof. Background technique [0002] β-carotene is one of the carotenoids. It is an orange-yellow fat-soluble compound. It is a stable natural pigment ubiquitous in nature. Many natural foods are rich in β-carotene. Among them, carrots are more abundant. Generally, carrots are biennial herbaceous plants of the genus Carrot in the Umbelliferae family, and are eaten as vegetables with fleshy roots. Carrots are rich in β-carotene. β-carotene is an antioxidant. Carotene can be converted into vitamin A, which helps to enhance the body’s immunity and detoxification. It is an indispensable nutrient for maintaining human health. It has significant functions in anti-cancer, prevention of cardiovascular disease, cataract and anti-oxidation. It plays an important role in the process of preventing epithelial cell canceration. It is helpful for cell reproduction and growth. It ...
