Aplikasi Minyak Nabati sebagai Coating pada Irisan Wortel (Daucus carrota) Beku dan Perubahan Mutu Selama Penyimpanan.

Abstract

Carrot is highly perishable commodity due to respiration. This process can decompose the macro molecule into carbon dioxide, water, and other micro molecule into this decomposing lead to softening of tissue. This damage could be reduced by fast freezing and then stored under frozen. The research was aimed to know the effect of freezing time and the kind of oil used as coating on color, texture, weight loss and total dissolved solids of the slice carrot during storage. The introduction studies carried out experiments on "trial and error" process of freezing and freezing conditions best obtained by using the freezer (-18oC). The result of this study shows oil that oil gave significant effect on the quality of carrot. The best oil for coating was corn oil that gave weight up to 0.11%, total dissolved solid in the range 4 to 6 brix, color of 67 till 70 Hue, violence 1.30 and 3.10 mm/s, and it was favored by consumers even after 54 day storage.
