Abstract

The objective of this project was to increase shelf life and partial CLARIFICATION of DATE FRUIT extract. Major factors affecting the physiochemical characteristics of DATE FRUIT extract, pH, extraction and CLARIFICATION method, were taken into consideration as variables and different treatments of date extract were made accordingly. The effect of each variable was monitored by measuring light transmission at 420 and 520 nm as color and clarity indices respectively as well as measuring soluble solids. The experimental trials were analyzed for pH and FORMIC ACID content. Total microbial, yeast and mold counts were also performed on the raw and clarified materials. The results indicated that the acids alone had no significant effect on color and clarity nor on had pectolytic enzymes. It was found that there were significant interaction effects between type of acid and enzyme in order to improve color and clarity. It was observed that employed process was effective in reducing total count of the product particularly due to application of acids.
