Proteolytic effect of starter culture during ripening of smoked horse sausage
Lu Shiling,Han Xianna,Yang yanbin,Li Baokun,Xu Chengjian,Wang Qingling 한국식품과학회 2017 Food Science and Biotechnology Vol.26 No.5
In this study, we assessed the effect of bacterial and endogenous enzymes on the proteolysis of smoked horse sausage. Commercial starter culture (Staphylococcus xylosus + Lactobacillus sakei) was used in smoked horse sausage. Cathepsin B + L and cathepsin B activities, microbiological growth, pH, and water activity (aw) were measured. Based on PCR-DGGE fingerprint analyses, the starter culture inhibited endogenous bacterial growth. During ripening, the residual activity of cathepsin B + L and cathepsin B was higher in batch C (control) than in batch S (containing starter cultures). The starter and endogenous enzymes promote the degradation of sarcoplasmic and myofibrillar proteins; however, the degradation of these proteins was higher in batch S than in batch C. Therefore, bacterial enzymes played a major role in the degradation of proteins during the ripening of smoked horse sausage.

Background: Radix et Rhizoma Ginseng (thereafter called ginseng) has been used as a medicinal herb forthousands of years to maintain people’s physical vitality and is also a noneorgan-specific cancer preventiveand therapeutic traditional medicine in several epidemiologic and preclinical studies. Owing tofew toxic side effects and strong enhancement on body immunity, ginseng has admirable applicationpotential and value in cancer chemoprevention. The study aims at investigating the chemopreventiveeffects of ginseng on cutaneous carcinoma and the underlying mechanisms. Methods: The mouse skin cancer model was induced by 7,12-dimethylbenz[a]anthracene/12-O-tetradecanoylphorbol-13-acetate. Ultraperformance liquid chromatography/mass spectrometry was used foridentifying various ginsenosides, the main active ingredients of ginseng. Comprehensive approaches(including network pharmacology, bioinformatics, and experimental verification) were used to explorethe potential targets of ginseng. Results: Ginseng treatment inhibited cutaneous carcinoma in terms of initiation and promotion. Thecontent of Rb1, Rb2, Rc, and Rd ginsenosides was the highest in both mouse blood and skin tissues. Ginseng and its active components well maintained the redox homeostasis and modulated the immuneresponse in the model. Specifically, ginseng treatment inhibited the initiation of skin cancer byenhancing T-cellemediated immune response through upregulating HSP27 expression and inhibited thepromotion of skin cancer by maintaining cellular redox homeostasis through promoting nuclear translocationof Nrf2. Conclusion: According to the study results, ginseng can be potentially used for cutaneous carcinoma as achemopreventive agent by enhancing cell-mediated immunity and maintaining redox homeostasis withmultiple components, targets, and links.
