The invention discloses a modifier for quick-frozen wonton wrappers. The modifier comprises sodium alginate, citric acid, vitamin C, calcium stearyl lactylate, sodium tripolyphosphate, sodium pyrophosphate, table salt, dietary alkali, semen cassiae gum and mannitol. The modifier for the quick-frozen wonton wrappers, disclosed by the invention, effectively solves the problems that quick-frozen wontons are easy to crack, the appearance, the color and the mouth feel of the quick-frozen wontons become bad, and the quick-frozen wontons are not resistant to cook with water, and besides, the made wonton wrappers are good in mouth feel and rich in nutrition. The modifier for the quick-frozen wonton wrappers, disclosed by the invention, is good in solubility, good in mixing property, high in safety, simple and convenient to use, and rich in nutrition; besides, the problems that the wonton wrappers are easy to crack due to thin wrappers and the color of the wonton wrappers is dark in the process of processing, cooking, freezing and melting the wonton wrappers can be solved.

The invention relates to a detection method of mannitol in cordyceps fungus powder (Cs-4). The method comprises the steps of 1, preparation of a test substance solution, wherein an appropriate amountof cordyceps fungus powder (Cs-4) is taken, weighed precisely and added into an ethanol solution, the mixture is weighed, heated for reflux, cooled and weighed again, lost weight is supplemented by the ethanol solution, filtering is performed, an appropriate amount of subsequent filtrate is taken and placed in an evaporation dish, the subsequent filtrate is subject to decompression drying to be almost dry, residues are dissolved into a volumetric flask through a mobile phase and pass through a 0.45-micron micropore filtering membrane, and subsequent filtrate is taken to serve as the test substance solution; and 2, preparation of a reference substance solution, wherein an appropriate quantity of D-mannitol reference substances is taken, weighed precisely and dissolved by adding the mobile phase, and the reference substance solution is obtained; and 3, determination, wherein the reference substance solution and the test substance solution are sucked respectively and precisely and injected into a liquid chromatograph, a chromatogram is obtained through determination, and the content of D-mannitol (C<6>H<14>O<6>) is calculated according to the chromatogram.

The invention belongs to the technical field of compound preparation. The invention relates to a preparation method of phosphatidylglycerol monosodium salt, in particular to a preparation method of phosphatidylglycerol monosodium salt containing two different side chains. The preparation method comprises the following steps: taking D-mannitol as an initial raw material, heating D-mannitol in acetone to generate 1,1,5,6-isopropylidene-D-mannitol; carrying out sodium periodate oxidation and sodium borohydride reduction to obtain iso-propylidene glycerol; carrying out condensation reaction with fatty acid containing an R1 element, then removing acetal protective groups in the presence of acid; selectively protecting primary hydroxyl by using a silane protective agent, reacting secondary hydroxyl with another fatty acid containing a R2 element, removing silane protection, reacting the de-protected product with phosphorus oxychloride and iso-propylidene glycerol, removing acetal protectivegroups by using an acid, and finally carrying out a sodium salt treatment to obtain a final product. The synthesis of phosphatidyl monosodium salt containing two different side chains can be realized,and the production process is simple, environment-friendly and easy to operate.
