The popularity of the plant Stevia (Stevia rebaudiana) has risen due to increasing use and interest in its sweet constituents called steviol glycosides. In recent years, these have been approved all over the world as food additives in the category of sweetener, hence they have received more attention and their use in food formulations has increased significantly. New techniques in growing stevia have resulted in new varieties with interesting steviol glycoside profiles. Also, new techniques to analyse the content of sweeteners in different matrices and the detection of new steviol glycosides with very pleasant sensory profiles has followed. The aim of this book is to present novel uses and manufacturing developments as well as to gather together up-to-date information across the whole developing area of steviol glycosides research.

Steviol Glycosides: Production, Properties, and Applications illustrates the health effects of steviol glycosides, presenting methods to preserve their stability, bioactivity and bioavailability during handling, extraction and processing. Beginning with biosynthesis, metabolism and health uses, the book also explores agronomic practices, toxicology and pharmacology, leaf drying, conventional techniques, non-thermal technologies, green recovery, membrane clarification technologies, chemical and enzymatic modifications, stability studies and food applications. This book is an excellent resource for food scientists, technologists, engineers, chemists, nutritionists, new product developers, researchers and academics with an interest in understanding steviol glycoside applications in the development of functional foods, nutraceuticals and pharmaceuticals. Assesses the biosynthesis, metabolism and health effects of steviol glycosides Covers three critical dimensions, including properties, recovery and applications Explores recovery, analysis and processing issues, also revealing industrial applications

Rebaudioside (Reb) D and M are the recent focus of the food industry to address the undesirable aftertaste of Reb A, which is the most commonly used steviol glycoside in natural sweetener stevia. The first study evaluated the sensory characteristics of Reb A, D, and M, compared to 14% (w/v) sucrose, using a consumer panel and explored the relationship between 6-n-Propylthiouracil (PROP) taster status (i.e., non-tasters, medium tasters, supertasters) and the perceived intensity of sweet and bitter tastes of the three steviol glycosides. The results showed that Reb D and M had sensory profiles that were closer to sucrose, compared to Reb A, but were associated with negative sensation, such as artificial, and Reb M was higher in lingering sweetness than sucrose (P

The mixture of s.rebaudiana stems and leaves will be extracted to get the stevioside. Stevioside is a diterpene steviol Glycoside which is produced by conventional process. It is used to sweeten soft drink,soya sauce, yoghurt and other food. It also good for diabetic patients. This research objective is to extract the steviol glycosides from the mixture of s.rebaudiana stems and leaves using ultrasound extraction technique and find their applications. The process normally include the extraction, pre-treatment, separation, purification and refining. These processes will use ultrasound technique and followed by High performance liquid chromatography analysis (HPLC). Ultrasound extraction technique is one of the techniques to extract the mixture of s.rebaudiana stems and leaves before the sample of the the mixture of s.rebaudiana stems and leaves is analyzed by HPLC. The mixture of s.rebaudiana stems and leaves will be in dry and powder condition before it extracted by ultrasound extraction technique using ethanol as a solvent. Power level that used in the extraction is 280 W and the time range is between 10min to 50min at temperature range of 200C to 600C. After that the analysis was performed using High performance liquid chromatography (HPLC). Using 30 min, 40 0C and 80% ethanol is the most suitable time, temperature and percent of solvent used to break the analyte and matrix bond and produce the steviol Glycoside in optimum yields. From this research we know that ultrasound extraction technique is most common technique and most suitable in order to extract the steviol glycosides from the mixture of s.rebaudiana stems and leaves. The optimum yield can afforded at extraction time of 30 minutes, extraction temperature of 40 0C and the percentage of ethanol of 80%. Extraction kinetic of steviol glycosides approved the second-order kinetic yielding good R2 values of 0.992.
