Abstract

The use of polar mangrove leaves extract (Avicennia marina) as natural preservative for white tofu was investigated. A factorial completely randomized design was used. Two factors were studied, namely immersion in polar mangrove leaves extract solution (with immersion and dyeing) and storage time (1, 2 and 3 days). All experiment was carried out in triplicates. The observed parameters were physical (texture and color), chemical (water content, pH value and total acidity), microbiological (total plate count) and sensory (flavor, texture and color) characteristics. The results showed that immersionin polar mangrove leaves extract solution had signnificant effect on color (lightness, chroma and hue), water content and total plate count, whereas storage time had significant effect on texture, pH value, total acidity and total plate count. However, interaction of the factors showed no significant effetcs on all parameters. The best treatments was white tofu immersed in mangrove leaves extract and stored for 1 days with the following characteristics: texture of 350,53 gf, lightness 50,67%, chroma 33,67%, hue 60,00, water content 82,87%, pH 5,23, total acidity 0,51 % dan total plate count 5,02 log CFU/g.
