Extraction of Non-alcoholic Drinks from Dates {date palm phoenix dactyliferal} Significant Factors and Optimum Value of the Significant Factors

摘要

Extraction of non-alcoholic drinks from dates was investigated by using treated water. The effect of extraction temperature of 30,70℃, extraction time of l,4h and ratio of dates/water of 100g: 500ml, 100g: 1000ml on product concentration and the optimum value of the significant factor were studied .The increasing of extraction temperature, time and ratio of dates to water were found to be highly significant in affecting the product concentration. Optimum ratio was 100g date: 500ml water. Optimum extraction time at 30℃ was 8 hrs, at 65℃ was 3hrs and at 98℃ was 1h. The study indicated the possibility of producing non -alcoholic carbonated drinks from dates. And product produced was found to be highly acceptable by consumer.
