RESUMO

The aim of this study was to investigate the effectiveness of Levilactobacillus brevis on the fermentation kinetics and flavor quality of radish paocai. Compared with spontaneous fermentation (SF), the radish paocai of inoculated fermentation (IF) using Levilactobacillus brevis PL6-1 as a starter could rapidly utilize sugar to produce acid, thus accelerating the fermentation process. The texture including hardness, chewiness, and springiness of the IF were all higher than that of the SF, and the IF paocai showed higher L value in color. L. brevis PL6-1 as a starter could increase the final levels of metabolites of mannitol (5.43 mg/g), lactic acid (543.44 mg/100 g) and acetic acid (87.79 mg/100 g). Fifteen volatile organic compounds (VOCs) were identified as key aroma-active compounds in radish paocai and 8 differential VOCs were considered as the potential markers. L. brevis PL6-1 could improve the levels of 1,8-cineole, 1-hexanol, hexanoic acid, 2-methoxy-4-vinylphenol, and eugenol, giving the radish paocai floral, sweet, and sour aroma, and reduce the unpleasant odor of garlic, onion, and pungent, contributed by erucin, diallyl disulfide, and allyl trisulfide. Sensory evaluation results showed that the appearance, taste, texture, and overall acceptability of IF paocai were all better than the SF group. Therefore, L. brevis PL6-1 could be a potential starter to improve the flavor and sensory quality for radish paocai fermentation.

RESUMO

Objective: Based on a retrospective cohort study, the study aims to investigate the effects of adipose plasma transfusion compared with normal plasma transfusion on adverse transfusion reactions, important functional indicators, and clinical safety in patients with parenteral nutrition (PN). Methods: One hundred and twenty inpatients who needed PN and plasma transfusion in Xianning Central Hospital from September 1, 2021, to March 31, 2022, were enrolled as the actual application verification cases. All the patients in the group noticed the informed consent form, and the normal plasma transfusion was set as the control group (n = 40), and the fat plasma transfusion was set as the study group. Mild adipose plasma transfusion was adopted in study group ① and moderate adipose plasma transfusion was used in study group ②, 40 cases in each group. The blood routine tests, blood lipids, blood coagulation, liver function tests, and the incidence of adverse reactions of blood transfusion were compared. Results: The comparison results of platelet count, red blood cell count, hemoglobin, and hematocrit among the three groups are as follows: study group ②> study group ①> control group (P < 0.05).The levels of blood lipids in the three groups, triglyceride, total cholesterol, high density lipoprotein, and low density lipoprotein were compared in group ②>group ①>control group (P < 0.05).The liver function tests indexes of the three groups were compared: ALT, AST, LDH: study ②study ①>control group. Regarding the incidence of adverse transfusion reactions, the incidence of adverse transfusion reactions in the study group was lower than in the control group (P < 0.05). Conclusion: Compared with normal plasma transfusion, the inpatients who need PN and plasma transfusion can effectively use the scrapped mild and moderate fatty plasma and reduce the plasma scrap rate. In the meantime, it has little effect on the function of the important indexes of the patients, and the incidence of adverse reactions of blood transfusion is low and the safety is high. Infusion of adipose plasma can also improve the effective individual and rational utilization of blood products. Trial registration: This trial is registered with chiCTR220005918.
