Problems solved by technology

Some products on the market, such as stevioside A3-60, stevioside A 3 -80, although the stevioside A component is 60% or 80%, resulting in an increase in the sweetness multiple from 200 times to 300 times or 350 times that of stevioside, but in fact the result of the oral test still has a rather bitter taste

Embodiment Construction

[0051] (Such as figure 1 Figure 5 As shown) a kind of steviol glycoside powder without bitter taste and its production method of the present invention adopts physical methods, and uses β-CD to contain the part of the bitter taste factor in steviol glycosides, that is, the aglycon part, thereby eliminating the bitter taste in steviol glycosides , and to achieve the above-mentioned part of the steviol glycoside containing the bitter and astringent taste factor, that is, the aglycone part, with β-CD, first, it is necessary to determine the part (glycon) and molecular structure and molecular weight of the stevioside bitter and astringent taste source, and secondly, it is necessary to estimate the glucoside The size and performance of the molecular structure of the steviol glycoside, and then equip the aglycon part and quantity of the inclusion complex β-CD inclusion steviol glycoside of the corresponding size, no matter when it is solid or in aqueous solution, so that it does not...

Abstract

The invention provides a method for producing stevioside, which adopts a physical method, and realizes the inventive purpose of eliminating bitter flavour in the stevioside by enveloping bitter flavour factor parts, namely aglycone parts, in the stevioside by using beta-CD. The process comprises steps of: (1) adding calcium carbonate in a folium sterviae dry leaf, mixing with water, and extracting extract liquid at a room temperature; (2) adsorbing a stevioside water solution by using an adsorption resin, meanwhile adding ethanol for elution, then obtaining another stevioside water solution; (3) desalting and decolouring the stevioside water solution of step (2) through a cation exchange resin, and obtaining another stevioside water solution; (4) decompress concentrating the stevioside water of the step (3), putting the beta-CD in an inclusion tank during the decompress concentration, obtaining a stevioside powder preparation after a spray, crystallization and drying process. The invention has advantages of simple process, low cost and good effect of removal of the bitter flavour in the stevioside.

Description

technical field [0001] The invention relates to a sweetener and its production and processing method, in particular to the technical field of plant extraction, health care products and food additives, and to provide a natural plant extract with strong sweetness and its production and processing method , the method achieves the purpose of improving the bitterness and astringency of natural plant glycosides and enhancing its sweet taste and mouthfeel. Background technique [0002] As we all know, steviol glycosides are the third largest natural sugar source after cane sugar and beet sugar, and also the first largest low-calorie natural sugar source, with only 1 / 300 of the calories of sucrose, making it an ideal low-calorie natural sugar source. Steviol glycosides are extracted and processed from the leaves of Stevia rebaudiana containing steviol glycosides. Stevia is easy to grow and rich in sources. It is a promising economic crop. [0003] Stevia cultivation originated in ...
