Abstract

The invention discloses a method for extracting the nutrient components of carrot through CO2 supercritical extraction, aiming to solve the technical problems that by adopting the existing extraction method of nutrient components of carrot, single component is extracted, the extraction efficiency is not high and a large amount of nutrient components are lost. The method comprises the following steps: (1) crushing: peeling fresh and disease-free carrot, cleaning, placing the cleaned carrot in a crusher to crush to 40-80 meshes of particles; (2) drying: drying the crushed carrot to ensure the water content to be 10-15%; (3) extracting: placing the dried carrot in a CO2 supercritical extraction material tank, adding carrying agent, performing CO2 supercritical extraction under the condition that the extracting pressure is 10-32MPa, the temperature is 20-60 DEG C and the CO2 flow rate is 20-25kg / h, and obtaining the extracting solution. The method of the invention is adopted to perform extraction to carrot, the extraction rates of beta-carotene and vitamin A are high; and the extracting solution also contains ginsenosides, fat, iron, calcium and saccharides, the bioactive constituents can be retained to the greatest extent, the extracted components are various and the purity is high.

Description

technical field [0001] The invention relates to a method for extracting nutritional components of carrots, in particular to a CO 2 A method for supercritical extraction of nutrients from carrots. Background technique [0002] Since the 1990s, with the in-depth study of a new generation of functional carotenoids, carotenoids have become new antioxidant active substances that have attracted widespread attention in the international pharmaceutical, dietary supplement, and functional food circles. The research and extraction of has also become a topic of increasing concern. [0003] Carotenoid is a general term for a class of natural pigments with functional properties. It is named carotene because it was first found in carrots. At present, more than 700 kinds of carotenoids have been discovered, more than 100 kinds related to food, and more than 20 kinds in the human body. The common ones are β-carotene, lycopene, lutein, zeaxanthin, cryptoxanthin , Astaxanthin, etc. The ca...
