Abstract

Strawberry was a fruit that was easily damaged. Therefore, a treatment was required to extend its shelf life. One of them by means of edible coating used liquid chitosan. The purpose of this study was to determine the shelf life of strawberries with liquid chitosan coating. The benefit of this research was to know the utilization of liquid chitosan applied to strawberry as edible coating, and to know the duration of storage of strawberry fruits coated with liquid chitosan. This study consists of preliminary research and main research. Preliminary research aims to determine the critical limits to be used as a reference in the main research. Based on acceptance test with microbe amounted 2,82x103, and texture equal to 12,23 mm / sec / g. The main objective of this study was to predict the storage life of strawberries by coating 3%, 2%, and 0% chitosan (control) at storage temperatures 15 C, 25°C, and 35°C for 0, 2, 4, 6, 8 ,and 10 days of storage used Arrhenius method. The main research results showed that the fruits age based on microbial quantity by coating of 3% liquid chitosan concentration at 15 ° C was 9.86 days, at 25°C was 5.38 days, and at 35°C was 3, 24 days. Saving age of strawberries with a 2% aqueous chitosan concentration at 15 ° C was 7.40 days, at 25°C was 3.98 days, and at 35°C was 2.23 days. The age of strawberries without liquid chitosan at 15°C is 4.42 days, at 25°C is 1.76 days, and at 35°C is 0.81 days. While the fruits age based on texture determination parameters with liquid chitosan coating concentration of 3% at 15°C was 9.25 days, at 25°C was 7.09 days, and at 35°C was 4.86 days. Saving age of strawberries with liquid chitosan concentration of 2% at 15°C is 6.26 days, at 25°C is 3.52 days, and at 35°C is 2.66 days. The age of strawberry fruits without liquid chitosan at 15°C was 4.98 days, at 25°C 3.45 days, and at 35°C was 2.11 days. Keywords: Liquid Chitosan, Arrhenius Method, Strawberries, Shelf life.
