Due to some inherent defects in soil cultivation, such as: the need to use pesticides to prevent and kill pests and diseases, there is a risk of pesticide residues; the cultivation environment, soil, water sources, fertilizers, etc. used for cultivation have the risk of being polluted by heavy metals and harmful The risk of microbial contamination; during the cultivation process, high concentrations of mineral salts must be irrigated into the soil, which eventually leads to salinization of the soil and damages the ecological balance; It is necessary to add a large amount of preservatives to prevent its deterioration, which greatly limits its application in high-end cosmetics

Abstract
The invention relates to a method for preparing preservative-free mesembryanthemum crystallinum extract from lyophilized mesembryanthemum crystallinum powder. The method comprises steps as follows: H1, raw material selection; H2, equipment cleaning; H3, freeze drying; H4, superfine grinding; H5, irradiation sterilization H6, ultrasonic extraction; H7, centrifugal impurity removal; H8, micro-pore filtration sterilization. The method is characterized in that: the technology is simple, hydroponic mesembryanthemum crystallinum planted in a plant factory is selected as a raw material, so that highquality of the extract is guaranteed, effective active ingredients of the mesembryanthemum crystallinum are completely reserved with a low-temperature cryodesiccation based powder preparation technology and an ultrasonic enhanced extraction technology, the prepared mesembryanthemum crystallinum extract contains no preservatives, and furthermore, the mesembryanthemum crystallinum extract is rich innutritional ingredients such as mineral substances, amino acids, inositol, beta-carotene, vitamins and the like, has whitening, freckle-removing, moisturizing, anti-allergic repairing and anti-agingeffects and the like, and can be used for preparing high-end cosmetics with moisturizing, soothing, whitening, freckle-removing, anti-allergic repairing, compacting and anti-aging functions and the like, and considerable economic benefit is produced.
Description
technical field [0001] The invention relates to the technical field of cosmetic production, in particular to a method for preparing a preservative-free extract of Bingye Rizhonghua by using Bingye Rizhonghua freeze-dried powder. Background technique [0002] Ice vegetable, also known as ice leaf Rizhonghua, is an annual herb of the Apricot family and the genus Rizhonghua. It is native to arid regions such as the Namib Desert in South Africa. It is characterized by a large number of large vesicular cells growing on the leaves and stems, which are filled with liquid and reflect light under the sun, just like ice crystals, hence the name. Ice leaf sunflower is a kind of halophyte with high nutritional value, which is often eaten raw by people or used to make cosmetics from its extract. [0003] At present, there are the following problems in the publicly reported extracts of Bingye Rizhonghua: (1) The raw materials used in the publicly reported Bingye Rizhonghua extracts all c...
