Problems solved by technology

[0003] However, most of the natural form of β-carotene exists in fruits and vegetables in a bound state, resulting in low release and utilization after ingestion, and low bioavailability. Substances, highly hydrophobic β-carotene cannot be directly transferred from the interior of plant tissues to the absorption site of intestinal epithelial cells, so how to improve the bioavailability of β-carotene is an important topic in food processing engineering

Abstract

The invention relates to a beta-carotene emulsion with high bioaccessibility. The beta-carotene emulsion with high bioaccessibility is prepared by subjecting oil-phase components and aqueous-phase components to homogenizing and emulsifying, the oil-phase components comprise carotene, camellia oil and olive oil, and the aqueous-phase components comprise sucrose ester, pectin and deionized water; wherein the mass percentage of the oil-phase components in the total components is 1-7%; the mass ratio of camellia oil to olive oil in the oil-phase components is 1: 1-1: 5; and the mass ratio of sucrose ester to pectin in the aqueous-phase components is 1: 0.5-1: 1. The beta-carotene emulsion with high bioaccessibility disclosed by the embodiment of the invention has the advantages of high bioaccessibility and good stability.

Description

technical field [0001] The invention relates to the technical field of food processing, in particular to a highly bioavailable beta-carotene emulsion and a preparation method thereof. Background technique [0002] Vitamin A is a fat-soluble vitamin. Vitamin A has various physiological functions such as promoting growth and reproduction, maintaining bone, epithelial tissue, vision and normal secretion of mucosal epithelium. Vitamin A and its analogs can prevent precancerous lesions. When lacking, it manifests as growth retardation and decreased dark adaptation ability to form night blindness. Due to the dryness, desquamation, hyperkeratosis, and decreased lacrimal gland secretion of the epidermis and mucosal epithelial cells, dry eye disease occurs. In severe cases, corneal softening, perforation and blindness occur. Respiratory epithelial cells become keratinized and lose their cilia, reducing resistance to infection. Vitamin A is an extremely important fat-soluble vitamin...
