Pengaruh Coating Kitosan dan Minyak Atsiri Kemangi terhadap Angka Kapang dan Penerimaan Produk Katsuobushi

Abstract

This study evaluates the effect of chitosan coatings by adding basil essential oil at different concentrations on the quality of katsuobushi during 14 days of storage at room temperature. This study aimed to determine the effect of adding basil essential oil to chitosan coatings in maintaining katsuobushi's physical, chemical, and microbiological quality during room temperature storage. The treatments included control (without coating), 1% chitosan (P1), 1% chitosan and 1% essential oil (P2), 1% chitosan and 1.5% essential oil (P3), and 1% chitosan with 2% essential oil (P4). The results of ANOVA analysis of mold number, total plate count (TPC), protein content, fat content, and sensory acceptance of katsuobushi with chitosan coating and basil essential oil were significantly lower (p<0.05) than the control treatment and chitosan coating treatment only after 14 days of room temperature storage. The 1% chitosan and 1% basil essential oil coating treatment showed the best quality characteristics of katsuobushi, with a mold number of 29 CFU/g, TPC of 3.87 log CFU/g, moisture content of 13.1%, 55.13% crude protein, 1.81% crude fat, and mean acceptance of appearance, aroma, texture, and taste were respectively 3.43; 3.43; 3.57; and 3.4. This study's findings indicate that adding basil essential oil to chitosan coatings can increase the effectiveness of chitosan in inhibiting microbial growth and maintaining the quality of katsuobushi during room temperature storage.
