The COVID-19 pandemic, which initially began in Wuhan, China, quickly spread to more than 206 countries, including Indonesia. The use of vaccines is a preventive measure that is quite effective in preventing transmission of COVID-19. COVID-19 is caused by SARS CoV-2 which is the result of mutations from SARS-CoV which have higher virulence properties and spread faster. As of April 7, 2020, the number of infected people has reached more than 1,350,045 people including 76,328 people have died. Although there is no specific drug to treat COVID-19, administration of drugs such as remdesivir, fapilavir and chloroquin phosphate could cure 293,665 patients. In addition to therapeutic measures, preventive measures such as increased immunity are important steps to prevent transmission of various types of diseases. The results showed that probiotics could increase immunity through crosstalk between probiotics and intestinal mucosa. Interaction between probiotics and intestinal mucosa could increase the formation of lymphocytes (B and T cells), interleukin mainly IL-10 and IL-1β, immunoglobulins especially IgA, NK and Th-17 cells. The formation of this component will directly increase the body’s immune system against transmission of various diseases including COVID-19

Processed foods such as sausages are easily spoiled or damaged due to their relatively high water content. Various preservatives can be added to sausages to maintain quality and extend shelf life. This study aims to determine the type of preservative that is good in extending the shelf life of sausages. The levels of preservatives (P) used were (P1) control, (P2) nitrite 0.3% (b/b), and (P3) bacteriocin 0.3% (v/v) at storage period (S) of (S1) 0 days, (S2) 3 days, (S3) 6 days, and (S4) 9 days. The observed variables were moisture content, ash, fat, protein, total plate count, and hedonic sensory analysis (color, aroma, taste, texture, and overall assessment). The observation results were tested using Analysis of Variance (ANOVA), which DNMRT further tested at the 5% level. The results showed that the interaction between P and S treatments had a significant effect (P < 0.05) on the hedonic organoleptic values of color, aroma, taste, texture, and overall assessment of sausages in each treatment. The preservatives added (P) to the sausage had a significant effect (P<0.05) on the value of moisture content, ash, fat, protein, total plate number, and hedonic sensory assessment. In contrast, the S treatment had no significant effect (P>0.05) on each parameter observed. Based on the results of the study, it can be concluded that the best treatment is P3S4 with preservatives used, namely bacteriocin and storage for 9 days with a moisture content value of 58.51%, ash 2.93%, fat 5.40%, protein 14.95%, total plate number 6x104 CFU/g, and hedonic sensory analysis on color preferred (score 3.54), aroma preferred (score 3.59), taste preferred (score 3.86), texture preferred (score 3.88), and overall assessment preferred (score 3.81) by panelists.
