| Abstract | ||
| The plant licorice is considered important plants as nutritionally and medically and economically, as a rich in phytochemical, vitamins and minerals, and being widely available, Research indicated the presence of many nutrients such as (proteins, Carbohydrates, vitamins and minerals) as well as presence of Glycyrrhizin which responsible of sweet taste, that allowing the possibility to use it as natural intensity sweetener with few calories in Sweetening of many food. This research is aimed to study the Stability of Glycyrrhizin toward the various manufacturing conditions such as (thermal treatment, pH of foods and microwaves), so three factorial experiments was implemented to find out the Stability as following: 100C° - 121C° - Microwaves [1150W] for 30-15-5 Min., respectively, under three levels of pH for each treatment 9.5 - 7.0 - 4.5 . It was found the high stability of Glycyrrhizin under 100C° - 121C° treatments under three levels of pH, as well as a significant increase in concentration at pH 9.5 - 4.5 at a temperature of 100C°. While the microwave treatment caused a significant decrease of Glycyrrhizin. | ||
