Objective: This study aimed to investigate the effect of Euglena gracilis on the quality and antioxidant activity of Chiffon cake and provide a reference for the application of E. gracilis in baked goods. Methods: E. gracilis powder (0.0%, 2.0%, 4.0%, 6.0% and 8.0%) with different contents were applied to Chiffon cake. The specific volume, water content, color, texture characteristics, sensory quality score, and antioxidant capacity of the cake were studied. Results: The addition of E. gracilis powder reduced the specific volume and the brightness of the cake, but had little effect on the water content. As the content of E. gracilis powder increased, the hardness, adhesiveness and chewability of the cake increased observably, while the elasticity, resilience and cohesion did not change a lot. The addition of E. gracilis powder significantly increased the antioxidant capacity of the cake, and statistical analysis showed that the antioxidant capacity was positively related to the content of E. gracilis powder (PE. gracilis powder was the highest. Conclusion: The application of E. gracilis powder into Chiffon cake significantly improved the antioxidant capacity, nutritional value of the cake and the quality of the cake as well.

ObjectiveIn order to discover the pulsed field gel electrophoresis (PFGE) serotypes and drug resistance of Salmonella agona (S. agona) in Sichuan Province during 2008 to 2018, so as to understand the contamination status of S. agona and provide reference data for outbreak warning, traceability investigation and antibiotic use strategy.MethodsA total of 61 S. agona strains after the serological and biochemical identification were analyzed by PFGE and tested for minimal inhibitory concentration of 14 antibiotics.ResultsThe isolates of S. agona were divided into 41 PFGE types, some strains isolated from clinical cases in different years and regions had the same PFGE type, one pork isolate had the same PFGE type as some clinical isolates. The antibiotic resistance test indicated 28 of the isolates were sensitive to 14 kinds of antibiotics, the other 33 strains showed different degrees of drug resistance, nearly half of the strains were insensitive to tetracycline; and there were 16 multidrug-resistant strains. All of the isolates were sensitive to imipenem.ConclusionThe PFGE types of S. agona isolated in Sichuan from 2008 to 2018 showed diversity, and they were sporadic prevalent in Sichuan Province. The drug resistance was serious with an increasing trend.
