Please select the most similar patent number from A, B, C and D. Which number is?
A natural plant product compound sweetener, prepared from momordica grosvenori dietary fiber, mogroside V, fructo-oligosaccharide, erythritol, palatinitol and malic acid by solution in water, filtration, vacuum concentration and spray drying.
A: A method for preparing compound sweetener particles of xylose and sucrose, wherein the compound sweetener particles comprise sucrose and xylose at a mass ratio of 40-60 : 40-60, and the proportion of particles with a particle size of 10-30 mesh in the compound sweetener particles is ≥ 70%. The method comprises the following steps: respectively crushing sucrose crystals and xylose crystals into powder, and uniformly mixing the obtained sucrose powder and the obtained xylose powder to obtain a mixed sugar powder, wherein the proportion of particles with a particle size below 100 mesh in the sucrose powder and in the xylose powder is 70% or more; dissolving sucrose crystals or mixed crystals of sucrose crystals and xylose crystals so as to prepare a sugar solution with a mass concentration of 40-60% and a viscosity of 3.5-40 mPa•s; and spraying the sugar solution, which acts as an adhesive, in an atomized form into the mixed sugar powder in a boiling state by means of a peristaltic pump for granulation, so as to obtain compound sweetener particles. By means of the method, xylose and sucrose are uniformly mixed, and the mixing ratio of xylose to sucrose is increased.
B: A sweetener comprising total Momordica grosvenori glycoside and preparation method thereof, said sweetener comprises total Momordica grosvenori glycoside, which comprises mogroside V. The sweetener is obtained by extracting Momordica grosvenori with pectinase, macroporous resin adsorption, and neutral alumina column decolorization. The composition is pale yellow or white, and is free of herbal and bitter taste of the Momordica grosvenori itself.
C: A solid  siraitia grosvenorii  theanine compound condiment, comprising a  siraitia grosvenorii  extract, theanine, a yeast extract, hydrolyzed animal protein, mushroom powder, a white kidney bean extract, and L-alanine.The preparation method comprises: thoroughly mixing the raw materials, putting the mixture into a granulator, and spraying water to form granules, and performing vacuum drying to obtain the condiment.
D: The present invention provides a method for producing a Siraitia grosvenorii extract using immobilized enzyme technology, comprising the following steps: hot water extraction, ceramic membrane filtration, desalination, decoloration, immobilized enzyme enzymolysis, and concentration. If necessary, a part of the enzymatic hydrolysate obtained in step (4) can be filtered by using a nanofiltration membrane, a Siraitia grosvenorii concentrated juice without mogrosides is obtained from the permeate of the nanofiltration membrane, and dry powder of a Siraitia grosvenorii extract is obtained from components retained by the nanofiltration membrane. The method of the present invention can simultaneously produce multiple kinds of liquid and solid Siraitia grosvenorii extract products, thereby satisfying various requirements of the market, and the yield of mogroside V is high. The content of mogroside V in the Siraitia grosvenorii concentrated juice reaches 3 to 8 wt%, and the mass content of mogroside V of the dry powder of the Siraitia grosvenorii extract is 40 to 60 wt%.
