Abstract

Fresh cheese is a dairy product produced from the coagulation process of milk using the rennin enzyme which does not require a ripening process. Extracellular proteolytic enzymes for cheese production can be produced from pineapple (Ananas comosus L. Merr) and microbes, such as Lactic Acid Bacteria (LAB) and yeast. This study aims to obtain Lactic Acid Bacteria (LAB) and yeast which have the potential for extracellular protease and Milk Clotting Activity (MCA) from fresh cheese and pinapple extract. The results showed that the total LAB from fresh cheese using pineapple was 5.6 x 10 5 CFU/g, from pineapple extract was 4.6 x10 5 CFU/ml, and from pasteurized milk was 1.9 x 10 4 CFU/ml. The total yeast from fresh cheese using pineapple was 5.1 x 10 4 CFU/g, from pineapple extract was 4.2 x 10 4 CFU/m and pasteurized milk was 4.0 x 10 3 CFU/ml. In this study found 8 LAB isolates from pineapple extract and fresh cheese had proteolytic activity with a proteolytic index value between 0.17 to 2.14 and had MCA abilities of 24 to 233 SU/ml. 5 yeast isolates from pineapple extract and fresh cheese that had proteolytic activity with a proteolytic index value between 1.14 to 2.14 and had MCA abilities of 1.7 to 2.1 SU/ml. LN-3 and YN-4 were the best isolates because they had a low proteolytic value with a high MCA value. BAL isolates from fresh cheese using pineapple belong to the genus Leuconostoc and Lactobacillus. Yeast isolates from fresh cheese using pineapple and Yeast from pineapple extract is belong to the genus Pichia. This study indicates that LAB and Yeast isolated from fresh cheese and pineapple extract cheese have extracellular proteolytic potential and Milk Clotting Activity (MCA).

Abstract

Buffalo meat is tough because buffalo are usually slaughtered when they are old. Apart from that, the high water and protein content in buffalo meat causes the meat to be easily damaged, which can reduce the quality. To prevent or inhibit a decline in quality, preservation is necessary to produce diversified products. This research aims to determine the effect of using the papain enzyme with different percentages on the water content, cooking loss and organoleptic values of buffalo meat jerky. This research was carried out from November 24 to December 24 2023 at the Meat Processing Science and Technology Laboratory, Animal Husbandry Study Program, Faculty of Agriculture, and at the Food and Agricultural Products Analysis Laboratory, Agricultural Products Technology Study Program, Syiah Kuala University, Darussalam, Banda Aceh. This research used a Completely Randomized Design (CRD) consisting of 4 treatments and 4 replications, with the addition of the papain enzyme, namely (0%, 5%, 10% and 15%). The parameters observed were water content, cooking loss, and organoleptics. (taste, aroma, color, texture and tenderness). The final research results showed that the use of the papain enzyme had a significant effect (P<0.05) on the water content of buffalo meat jerky and tended to increase from P0 to P3. The results of statistical analysis using the papain enzyme had no significant effect (P>0.05) on the cooking loss value The Kruskal Wallis test results also showed that the use of the papain enzyme at different percentages had a significant effect (P<0.05) on taste, but the use of the papain enzyme at different percentages had no effect (P>0.05) on color, aroma, texture. , and tenderness.. The use of 10% papain enzyme (P2) produced meat with the best organoleptic value, water content, and cooking loss.

Abstract

Goat milk have disadvantage of short shelf life and prengus smell. The short shelf life can be handled by pasteurization and the smell of prengus can be reduced by adding ingredients that contain antioxidants, one of which is purple sweet potato leaves. The aim of this study was to examine the organoleptic quality of pasteurized goat milk with the addition of purple sweet potato leaf extract. The experimental design used was a completely randomized design with four different concentrations of purple sweet potato leaf extract (0%, 2%, 4%, and 6%) with five replications. Variables observed were color, smell, langu (unpleasant) taste, prengus taste, texture, and preferences. Data were analyzed using analysis of variance (ANOVA) at the 5% level. Significantly different data were further tested using Duncan's Multiple Range Test (DMRT). Results showed that the addition of purple sweet potato leaf extract at a concentration of 2-6% had an effect (P<0.05) on color, smell, langu (unpleasant) taste, texture, and preferences but had no effect on the prengus taste. The most purplish color is obtained at a concentration of 6%. The least prengus smell is obtained at a concentration of 4%. The lowest langu (unpleasant) taste, the most characteristic texture of milk, and the highest preference is obtained at a concentration of 0%.
