The invention provides an improved method of a fruit, vegetable and beef type quick-frozen dumpling. The improved method comprises the following steps: adding sorbic acid and clear water respectively accounting for 0.4% of the total weight of stuffing into the stuffing, and uniformly mixing; feeding the uniformly mixed stuffing into a centrifugal machine, and carrying out centrifugal treatment; wrapping the stuffing with dumpling wrappers to form dumplings, then spraying carboxymethyl chitosan solution onto the surfaces of the dumplings, then taking out the dumplings, feeding the dumplings into a dryer, drying until white and dry spots are formed on the surfaces of the dumplings, and taking out the dumplings; covering the dried dumplings with hot vinasse, and then putting the dumplings into hypochlorous acid aqueous solution to be wetted; immediately putting the wetted dumplings into a cold storage at the temperature of -40 DEG C to be frozen, then packaging, and then carrying out low temperature freezing. The improved method provided by the invention has the advantages that the dumpling wrappers cannot be bubbled after being treated, the stuffing can well fit the dumpling wrappers, and the quick-frozen dumplings cannot produce pathogenic bacteria after being stored for a long time, especially the dumplings wrappers of the quick-frozen dumplings cannot be broken when being cooked.

The invention discloses a high performance liquid chromatographic analysis method of benzoic acid and sorbic acid in toothpaste and belongs to the technical field of analysis. High performance liquidchromatography is adopted to respectively detect a blank sample, a sample solution and a standard curve solution, and the blank sample, a standard curve, a sample, a sample and a standard curve are sequentially detected (notes: the number of feeding the sample between the two standard curves should not exceed 15, and a quality control sample or a standard curve needs to be added therebetween if the number exceeds 15). The method can quantitatively analyze content of benzoic acid and sorbic acid in a toothpaste sample quickly and accurately and can be used by market regulatory authorities for monitoring quality of commercially available toothpaste products. The method has the advantages of accurate detection result and reliability.
