ATP bioluminescence rapid detection of total viable count in soy sauce.

The adenosine triphosphate (ATP) bioluminescence rapid determination method may be useful for enumerating the total viable count (TVC) in soy sauce, as it has been previously used in food and beverages for sanitation with good precision. However, many factors interfere with the correlation between total aerobic plate counts and ATP bioluminescence. This study investigated these interfering factors, including ingredients of soy sauce and bacteria at different physiological stages.

Determination of catechin in lotus rhizomes by high-performance liquid chromatography.

A novel method was developed to analyze lotus rhizome polyphenolic catechin using high-performance liquid chromatography (HPLC). The retain time of catechin was 14.72 min under the optimized condition.

[Progress of molecular imprinting technique on the determination of pesticides residues].

People have paid a more attention to the pesticides residues, so the rapid detection method is required. In this paper the application of molecular imprinting technique on the detection of pesticides residues was reviewed, including recognition principles, preparation, current applications, problems and its future.
