Effect of Lactic Acid Bacteria and Yeasts towards Chemical, Physical and Organoleptic Qualities of Mutton Salami

Abstract

Mutton has exceptional qualities such as smell, high consistency, and huge muscle fat, which makes mutton are restricted to consume. To expand mutton utilization, diversification with proper innovation is important. Salami is one of the proper mutton products that required starter such LAB that can deliver metabolites to change the texture, taste, and odor of meat. Other than LAB, yeasts additionally show up in meat processing, particularly in salami fermentation, which can build the meat taste and odor. The study aimed to identify the chemical, physical (water holding capacity, tenderness, and pH) and organoleptic (odor, color, texture, and taste) quality of mutton salami. Completely Randomized Design (CRD) was used as an experimental design with starters of Lactobacillus Plantarum as lactic acid bacteria (LAB) and yeasts, i.e. Cryptococcus humicolous and Trichosporon beigelii. The treatments were divided into 5 levels, i.e. R1 (0.5% LAB: Yeast 0.5%), R2 (1% LAB: Yeast 1 %), R3 (1.5% LAB: Yeast 1.5%), R4 (2% LAB: Yeast 2%), and R5 (2.5% LAB: Yeast 2.5%), with four replications. Analysis of variance was used to find out the treatment effect, and the Duncan Multiple Range Test was used to find out the difference between any treatments. The results show that the addition of Lactobacillus Plantarum from 0.5% to 2.5% and yeast Cryptococcus humicolous, Trichosporon beigelii from 0.5% to 2.5%, did not significantly affect chemical and physical quality, while water holding capacity and organoleptic test, i.e., color, odor, and texture showed significant effects except taste.
