Quality improvement of Indonesia traditional snack " Gandos" through the substitution of grated coconut on sensory, chemical characteristics, and TPC value

Abstract

Gandos or pancong is a traditional snack, a type of semi-wet cake that is easily damaged and have a short shelf life. The quality of gandos is easily decreased because this snack is made from grated coconut which easily meets lipid oxidation. Quality improvement of gandos is needed to increase the selling value. The purpose of this study is to improve the quality of gandos by evaluating the sensory, chemical, and microbiological characteristics. The experimental design used was a one-factor Completely Randomized Design with three different treatments of coconut, namely F1 (coconut flour), F2 (pasteurized grated coconut), and F3 (boiled grated coconut). The tests carried out were sensory characteristics (appearance, aroma, flavor, texture, & overall), chemical characteristic (free fatty acid, moisture content, and ash content), and microbiological characteristic (total plate count). The hedonic test result showed that gandos with pasteurized grated coconut have the highest acceptance. This gandos has 36.601% of moisture content, 2.473% of ash content, 0.537% of FFA, and 4,4 x 103 CFU of TPC value. Gandos with pasteurized grated coconut has lower moisture content compared to the control. Based on the TPC test, gandos were not safe to consume in the 24th hour.
