Appearance and color in tempe are change during the fermentation, and would be the important factor in the consumer’s purchase decision. The purpose of this study was to determine the influence of four packaging types (plastic, banana leaf, teak leaf, and waru leaves) to the appearances and color indexes during tempe fermentation. The digital image analysis was used to compared the tempe surface appearance and color between the samples up to 120 h fermentation. The results showed that the use of different types of packaging affected the tempe appearance and color. Tempe packed with teak leaf more quickly decreased the value of L*, increase the value of b*, and increased the occurrence of black spots on the surface. The plastic gave the most stable color changes throughout tempe fermentation, followed by waru leaf, banana leaf, and teak leaf.
