preparation example Construction

[0027] The embodiment of the present invention provides a preparation method of lycopene-rich yeast extract, comprising the following steps:

[0028] (1) Strain activation: transfer the Rhodotorula viscosus strain from the storage slope to the activation medium under aseptic conditions;

[0029] (2) Preparation of seed solution: inoculate the activated Rhodotorula viscosus strain from the activated medium into the seed medium for expanded cultivation to obtain the seed solution;

[0030] (3) Liquid fermentation: Inoculate the prepared seed solution into the fermentation medium for liquid fermentation;

[0031] (4) Obtaining of yeast extract: after the fermentation, the fermentation liquid is collected, centrifuged, washed with water, and then processed by enzymatic digestion and microwave crushing.

[0032] In some of these embodiments, the activation medium formula described in the step (1) is: glucose 10-30 g / L, peptone 5-15 g / L, yeast extract powder 5-15 g / L, agar 10 -30 ...

Abstract

The invention discloses a preparation method of a lycopene-rich yeast extract. The method is characterized by comprising the following steps of (1) bacterial strain activation; (2) seed liquid preparation; (3) liquid state fermentation; (4) yeast extract obtaining. The lycopene-rich yeast extract is prepared through the specific technological processes such as bacterial strain activation, seed liquid preparation, liquid fermentation and enzymic digestion synergistic microwave crushing methods; rich yeast nutrition active substances such as small molecule peptide, free amino acid, vitamin, nucleic acid and nucleotide are contained; the nutrition performance of yeast degradation substances and the antioxidation performance of lycopene are realized; good cosmetic development values are realized.

Description

technical field [0001] The invention relates to the field of cosmetics, in particular to the preparation of a lycopene-rich yeast extract and its application in cosmetics. Background technique [0002] Lycopene, also known as ψ-carotene, is a natural pigment with the molecular formula C 40 h 56 , belonging to acyclic open-chain unsaturated carotenoids, its molecular structure contains up to 11 conjugated double bonds, the structural formula is as attached figure 1 shown. [0003] It is a low-polarity polyunsaturated aliphatic hydrocarbon, easily soluble in polar oils such as vegetable oil, caprylic acid / capric triglyceride, and insoluble in polyols such as butylene glycol, glycerin, and 1,3-propanediol. Insoluble in water. Lycopene is easily oxidized and isomerized. Therefore, in the process of extraction, processing and storage, the influence of external factors such as temperature, pH, reducing agent, metal ions and ultraviolet rays must be considered. The ability of ...
