Problems solved by technology

[0043] The technical problem to be solved by the present invention is that it is often difficult to eliminate the bitterness and astringency of the sweetener composition based on rubusoside, and has a relatively heavy after-sweet taste, which limits its application range as a natural high-sweetness sweetener; The invention provides a compound sweetener for improving the bitterness and lasting sweetness of rubusoside, which solves the problems of odor, thick taste and sweetness saturation, so that the bitterness and astringency of the obtained rubusoside compound sweetener disappear, and the sweetness The duration of the taste is less than 10 seconds; the present invention uses the mucus and concentrated juice from okra and rubusoside to compound in a specific ratio, without using complicated formulas, and is cheap and easy to obtain, with great commercial advantages

Embodiment 1

[0109] This embodiment includes the following steps:

[0110] (1) Preparation of okra mucus:

[0111] ①Extraction: Take 100kg of young okra fruit, break it into long thin pieces with a width of about 5mm with a medicine cutter, and put it into 1m 3 In a stirring tank, use water as a solvent, and extract with stirring at a room temperature of 17°C. Extract 2 times, add 600L of water for the first time, extract for 2.0h; add 500L of water for the second time, extract for 1.5h. After each extraction and filtration, the residue of the first extraction is then extracted for the second time. Combine the first and second extracts to obtain 1100L of water extract; the extraction residue after the second extraction is collected in a separate device.

[0112] ② Clarification: First pass the water extract through a disc centrifuge, and then through a complete set of ceramic membrane equipment with a pore size of 500nm. After feeding the feed liquid, add 300L of purified water to wash...

Embodiment 2

[0128] (1) Preparation of okra mucus:

[0129] ①Extraction: Take 100kg of young okra fruit, break it into long thin pieces with a width of about 7mm with a medicine cutter, and put it into 1m 3 In a stirring tank, use water as a solvent, and extract with stirring at a room temperature of 26°C. Extract 2 times, add 600L of water for the first time, extract for 2.0h; add 500L of water for the second time, extract for 1.5h. After each extraction and filtration, the residue of the first extraction is then extracted for the second time. Combine the first and second extracts to obtain 1100L of water extract; the extraction residue after the second extraction is collected in a separate device.

[0130] ② Clarification: first pass the water extract through a disc centrifuge, and then through a complete set of ceramic membrane equipment with a pore size of 300nm. After feeding the feed liquid, add 300L of purified water to wash the upstream liquid of the ceramic membrane, and combin...

Embodiment 3

[0146] (1) Preparation of okra mucus:

[0147] ①Extraction: Take 100kg of young okra fruit, break it into long thin pieces with a width of about 4mm with a medicine cutter, and put it into 1m 3 In a stirring tank, use water as a solvent, and extract with stirring at a room temperature of 8°C. Extract 2 times, add 600L of water for the first time, extract for 2.0h; add 500L of water for the second time, extract for 1.5h. After each extraction and filtration, the residue of the first extraction is then extracted for the second time. Combine the first and second extracts to obtain 1100L of water extract; the extraction residue after the second extraction is collected in a separate device.

[0148]② Clarification: First pass the water extract through a disc centrifuge, and then through a complete set of ceramic membrane equipment with a pore size of 500nm. After feeding the feed liquid, add 300L of purified water to wash the upstream liquid of the ceramic membrane, and combine ...

Abstract

The invention relates to a compound sweetener for improving the taste of rubusoside. The raw materials used in the preparation method include: okra young fruit mucus, okra concentrated juice, rubusoside extract and erythritol, provided that rubusoside The mass of rubusoside in the extract is 0.5-2% of the total mass of okra young fruit mucus and okra concentrated juice. The method of the invention increases the thick mouthfeel through the okra young fruit mucus, and increases the sweetness saturation of the okra concentrated juice after roasting and decolorization; the sweetness time is less than 10 seconds, and the bitterness of rubusoside is suppressed. The mouthfeel and sweetness duration of the compound sweetener provided by the invention is close to that of sucrose, and is a low-calorie, pure natural sweetener which can replace sucrose.

Description

technical field [0001] The invention relates to the field of compound sweeteners, in particular to a compound sweetener for improving the taste of rubusoside and a preparation method thereof. Background technique [0002] Rubus is prepared from the leaves of Rubus, a plant of the genus Rubus in the family Rosaceae, including sweet tea, Guangxi sweet tea, Shunhuangshan sweet tea, etc., through a series of separation and extraction steps. [0003] The rubusoside mainly includes: (1) R70-80 rubusoside, the process steps mainly include crushing, extraction, filtration, chromatography, decolorization, concentration, drying, etc., wherein the content of rubusoside is 70-80%, and it is a yellow-green powder; (2) R80-90 rubusoside, the process steps mainly include crushing, extraction, filtration, chromatography, membrane separation, decolorization, concentration, drying, etc., wherein the content of rubusoside is 80-90%, and it is a milky white powder; (3) R90-99 rubusoside, its p...
