Embodiment 1
[0029] A production process for extracting high-purity rubusoside from Guangxi sweet tea leaves, comprising the following steps:
[0030] (1) Extraction: Take 1000kg of Guangxi sweet tea leaves, crush them and put them into an extraction tank, use tap water to extract 3 times in a slightly boiling state, add 8, 6, and 7 times the amount of tap water, and extract the first batch of materials for the third time As the first extraction solution of the second batch of materials, the extraction time is 1.5h, 1h, and 1h respectively, and the filter residue after each filtration enters the next extraction;
[0031] (2) Concentration: Concentrate the first two Guangxi sweet tea extracts to three times the weight of the dry sweet tea leaves, about 3000L;
[0032] (3) Flocculation and clarification: Cool the concentrated solution to 40~45°C, and then turn on the steam to keep the temperature within this range; add 0.3% water-soluble chitosan by weight of Guangxi sweet tea raw material, ...

Abstract
The invention discloses a production process for extracting high-purity rubusoside from Guangxi sweet tea leaves, which includes extraction, concentration, flocculation clarification, centrifugal separation, macroporous resin refining, ion exchange resin decolorization, desalting resin desalination, compound decolorization, and concentration Finally, the thick paste is spray-dried to obtain a milky white to white powder with a high-purity rubusoside product with a rubusoside content of ≥98%. The advantages of the present invention are: industrialized mass production of rubusoside ≥ 98%, high-quality sweet tea extract with milk white to white color and bitter taste after removal, solves the problem that there is no batch supply of this product in the market, and occupies high-end sweet tea. Taste market; find a feasible production process route, mass production rubusoside products. According to the chemical composition characteristics of Guangxi sweet tea leaves, the key production industrial links such as flocculation clarification, macroporous adsorption resin purification and debittering, ion exchange resin decolorization and debittering, desalting resin desalination and debittering, and compound decolorization are effectively combined.
Description
technical field [0001] The invention relates to the extraction of rubusoside, in particular to a production process for extracting high-purity rubusoside from Guangxi sweet tea leaves. Background technique [0002] Commercially available sweet tea extract (specification: 70% rubusoside, HPLC detection) is made from dried leaves of Rubus Suavissmus S and Lee, the sweet tea of the genus Rubus of Rosaceae, extracted with water→filtered→macroporous resin→ion resin→concentrated→ For products produced by drying and other processes, the purity of the active ingredient rubusoside is ≤74%, the color is light yellow, and has a bitter aftertaste, which limits the market for this product. [0003] Sweet tea mainly contains rubusoside, sweet tea polyphenols, flavonoids, ellagic acid, protein, amino acid, chlorophyll and other ingredients, which are not easy to separate and purify, making it difficult for the purity and color of the product rubusoside to meet high-quality requirements, ...
