Pengaruh Konsentrasi Gula dan Lama Penyimpanan terhadap Mutu Manisan Basah Batang Daun Pepaya

Abstract

The aim of this research was to determine the effect of concentration of sugar and storage time on the quality of petiole of papaya wet candy. This research was conducted in December 2015 until January 2016 in Food Chemical Analysis Laboratory, Agriculture Faculty, North Sumatera, Medan. This research was using factorial Completely Randomized Design with two factors, i. e: concentration of sugar (G) (40%, 50%,60% and 70%) and storage time (L) (2 days, 4 days, and 6 days). The analyzed parameters were moisture content (%), vitamin C content (mg/100 g sample), total soluble solid (oBrix), solid gain (%), water loss (%), crude fiber content (%), total microbe (LOG CFU/g), total sugar (%), and hedonik value of colour, texture, taste, and score value of taste. The results showed that concentration of sugar had highly significant effect on moisture content (%), vitamin C content (mg/100 g sample), total soluble solid (oBrix), water loss (%), solid gain(%), total microbe (LOG CFU/g), total sugar (%) and score value of taste and had no effect on crude fiber content (%), hedonik value of colour, and texture. Storage time had highly significant effect on vitamin C content (mg/100 g sample), total soluble solid (oBrix), and total sugar (%) and had no effect on moisture content (%), water loss (%), solid gain (%), crude fiber content (%), total microbe (LOG CFU/g), hedonic value of colour, texture, taste, and score value of taste. The interaction of the two factors had highly significant effect on vitamin C content (mg/100 g sample), and had significant effect on total soluble solid (oBrix), and total sugar (%). Concentration sugar of 70% and storage time in 4 days was the best treatment and acceptable.
