Physical and Chemical Analysis and Quality Control of Liuzhou Pre-Packaged River Snails Rice Noodles
In this paper,indicator titration,flame atomic absorption spectrometry and naphthalene ethylenediamine hydrochloride were used to determine the peroxide value,lead and nitrite content in prepackaged Luosifen.Through visiting Luosifen prepackaging enterprises of different brands,15 prepackaged Luosifen samples are randomly collected and tested in our laboratory and third-party testing companies.The results showed that the lowest value of peroxide value was 0.011 g/100 g,the highest value was 0.097 g/100 g,and the average value was 0.048 g/100 g.The minimum lead content is 0.014 mg·kg-1,the maximum value is 0.123 mg·kg-1,and the average value is 0.047 mg·kg-1.The lowest value of sodium nitrite content is 0.254 mg·kg-1,the highest value is 3.113 mg·kg-1,and the average value is 1.452 mg·kg-1.It indicates that the physical and chemical analysis results of prepackaged Luosifen meet the local product standard of Luosifen.Through the analysis of physical and chemical indexes of prepackaged Luosifen,this paper discusses the quality control of prepackaged Luosifen,and provides a reference basis for establishing and improving the quality safety system of prepackaged Luosifen and standardizing the safety production of enterprises.
