Problems solved by technology

[0004] First, the existing water-soluble lutein ester additives are not ideally water-soluble
And in order to improve its water solubility, a large amount of additives are often added, which in turn leads to the problem of low lutein ester content
The water-soluble lutein ester additive is used as an additive after all. When the lutein ester content in the water-soluble lutein ester additive is too low, in order to make the lutein ester content in food or medicine meet the standard, it is necessary to increase the water solubility. The addition of lutein ester additives leads to an imbalance in the formulation of food or medicine, especially for tablet medicines with limited gram weight and liquid drinks that require viscosity and clarity
[0005] Second, after the existing water-soluble lutein ester additives are dissolved, the liquid clarity is not high, and it is unstable, and it is prone to discoloration or precipitation after long-term storage
Lutein esters are often added to beverages. Transparent packaging is a common packaging for beverages. However, the existing water-soluble lutein ester additives have low clarity and instability. Sales have brought adverse effects, limiting the application of water-soluble lutein ester additives in the field of beverages

Abstract

The invention discloses lutein ester water-soluble granules and a preparation method thereof, and belongs to the field of food additives. The granules comprise the following raw materials in parts byweight: 1 part of lutein ester, 2-10 parts of an emulsifier, 0.01-1 part of an antioxidant and 1-20 parts of a carrier. The preparation method comprises the following steps: 1) respectively crushing,sieving or filtering the lutein ester, the emulsifier, the antioxidant and the carrier; 2) mixing the lutein ester, the emulsifier, the antioxidant and the carrier in parts by weight, and heating theraw materials to 55-80 DEG C to obtain a mixture; and 3) adding the mixture into a hot melt extruder, performing extruding at 100-150 DEG C for 2-5 minutes, performing cooling, crushing particles, andperforming screening to obtain the lutein ester water-soluble granules. According to the lutein ester water-soluble granules and the preparation method thereof, the obtained lutein ester water-soluble granules are good in water solubility, high in lutein ester content and high in transparency after being dissolved.

Description

technical field [0001] A water-soluble lutein ester granule and a preparation method thereof belong to the field of food additives. Background technique [0002] Lutein ester, chemical name lutein dipalmitate (CAS registration number: 547-17-1), is a kind of oxygen-containing carotenoid ester, which widely exists in vegetables, flowers, fruits and some algal organisms . The lutein in lutein ester can absorb a large amount of blue light close to ultraviolet light, so it can filter the blue light that damages photoreceptors and retinal pigment epithelium. Timely supplementation of lutein can prevent vision loss and blindness caused by age-related macular degeneration (AMD) . In addition, lutein also has physiological functions such as anti-oxidation, anti-cancer, anti-mutagenesis, and delaying arteriosclerosis. It is a functional pigment with natural nutrition and health. Chinese Ministry of Health's Announcement No. 8 in 2007 approved lutein ester as a nutritional enhancer...
