Embodiment 1
[0080] This embodiment provides a method for preparing a sweet composition of Rubus cotyledon from Rubus cotyledon, specifically comprising the following steps:
[0081] 1) Pre-treatment: Take the organic Rubus rubus more than two years old and pick dry leaves in October: 20kg (rubusoside content 5.2%), control the moisture content in the dry leaves to about 15%, crush them, adjust the wind speed for cyclone separation, and collect The mesophyll fragments are sent to the extraction process.
[0082] 2) Extraction: Pour the mesophyll fragments into a high-pressure jet extraction kettle, the extraction solvent is purified water, the extraction temperature is 40°C, the fluid pressure is 50MPa, the ratio of solid to liquid is 1:15, and the extraction time is 30min. Machine centrifugation, ceramic membrane filtration to obtain the extract.
[0083] 3) Dephenolic hydroxyl components: 40L of XAD761 macroporous adsorption resin with a phenolic skeleton structure on the extract, at a ...
Embodiment 2
[0087] This embodiment provides a method for preparing a sweet composition from the cotyledon of Rubus sweet leaf, which specifically includes the following steps:
[0088] 1) Pre-treatment: Take the organic sweet leaf rubus of more than two years old and pick dry leaves in October: 2000kg (rubusoside content 4.34%), control the moisture content in the dry leaves to about 15%, crush them, adjust the wind speed of the inlet to carry out cyclone separation, and collect The mesophyll fragments are sent to the extraction process.
[0089] 2) Extraction: send the mesophyll fragments into two sets of continuous countercurrent extraction units connected in series, successively pass through the continuous countercurrent extraction unit A, juice extractor A, extract continuous countercurrent extraction unit B, juice extractor B, and contact the mesophyll fragments with pure water The extraction time is 40 minutes, and the pure water used in the extraction process is 8000L. The extract...
Embodiment 3
[0094] This embodiment provides a method for preparing a sweet composition from the cotyledon of Rubus sweet leaf, which specifically includes the following steps:
[0095] 1) Pre-treatment: Pick dry leaves of Rubus chinensis above biennials in November: 2000kg (rubusoside content 4.95%), control the moisture content in the dry leaves to about 12%, crush them, adjust the wind speed for cyclone separation, and collect mesophyll fragments , sent to the extraction process.
[0096] 2) Extraction: Send the mesophyll fragments into the continuous countercurrent extraction unit, the extraction time of the mesophyll fragments in contact with pure water is 90 minutes, and the pure water used in the extraction process is 12000L. The extraction temperature is 60°C, the juice is squeezed with a juicer, and the extract is obtained by filtering with a ceramic membrane.
[0097] 3) Dephenolic hydroxyl component: 2000L polyacrylic acid type macroporous adsorption resin LX-17 with skeleton s...
