Problems solved by technology

[0004] The traditional extraction and refining process of Mogroside mainly uses inorganic adsorbents and inorganic decolorizers, such as activated carbon, magnesium oxide series, magnesium silicate series, etc. The operation process is complicated and cannot be industrialized
Because saponins are extremely large and difficult to separate from pigments, most of the current processes generally use water or a certain amount of water-containing ethanol heating extraction, resin adsorption separation and refining technology, but the combination of this technology is mainly for Luo Han Guo gourd Extraction and refining of alkane triterpene glycosides, other beneficial ingredients and flavor substances are basically lost, and the utilization rate of resources is relatively low

Embodiment 1

[0040] Raw material: dried Luo Han Guo 2kg. Main equipment: high-speed agitator, pneumatic press, inorganic membrane filter, ultrafilter, reverse osmosis concentrator, stirring extractor, thin film evaporation concentrator, spray dryer.

[0041] Preparation process:

[0042] 1. Mangosteen is crushed into 100 mesh fine powder;

[0043] 2. Take 6 kg of purified water at room temperature and mix well with Luo Han Guo powder, and stir at high speed for 30 minutes;

[0044] 3. Release the extract and squeeze it through the press to collect the squeeze liquid;

[0045] 4. Continue to extract the squeezed slag for 3 times according to step 2 and step 3, and obtain about 24kg of extract;

[0046] 5. Combine the extracts, filter through a 0.8 μm inorganic membrane filter and a 10,000 Dalton ultrafilter successively, collect about 20 kg of the filtrate, concentrate to a relative density of 1.15 with a reverse osmosis concentrator, and quantitatively encapsulate to obtain product I. ...

Abstract

This invention relates to a method for preparing Momordica grosvenori extracts at a low temperature, especially a method for preparing food raw material extract rich in vitamin C and sweetener extract rich in mogroside by combination of multi-stage fine filtration and polyol extraction at 40 deg.C or below. The method has such advantages as high resource utility, short production cycle, and retained Momordica grosvenori taste in the extracts.

Description

technical field [0001] The invention relates to an extraction and preparation process of Luo Han Guo extract, especially a combination of multi-stage precision filtration and polyol extraction technology for extraction at a temperature of 40°C or below, and simultaneously prepare nutritional components rich in vitamin C. The preparation process of main food raw material extract and mogroside-based sweetener extract. Background technique [0002] Luo Han Guo fruit contains a variety of cucurbitane triterpene glycosides, collectively known as mogrosides; this type of compound is the main active substance in Luo Han Guo fruit, accounting for about 4% of the dry fruit weight. Most of these compounds are sweet ingredients or slightly sweet substances, which can be used as sweeteners for food and dishes, and are ideal sugar substitutes for diabetics. In addition to strong sweet ingredients such as cucurbitane triterpene glycosides, it also contains low-sweet ingredients such as D...
