Book Description :

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.

Book Description :

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 methanol 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% methanol 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 methanol of 80%. Extraction kinetic of steviol glycosides approved the second-order kinetic yielding good R2 values of 0.997 and k values of 0.0301.

Book Description :

Stevia rebaudiana (stevia) is gaining agricultural importance due to its natural production of non-caloric steviol glycosides, which can be extracted and incorporated into natural, zero-calorie sweeteners. Of the several steviol glycosides produced by stevia, those produced in the largest concentrations, such as rebaudioside A, are often criticized by consumers as having a bitter aftertaste. Other glycosides, such as rebaudioside D, are reported to have a superior flavor profile, but are produced in much smaller concentrations. The environmental and genetic control of steviol glycoside synthesis is poorly understood. The objectives of this research were: 1) to determine how daily light integral (DLI) influences glycoside concentrations and relative proportions, particularly for rebaudioside D and 2) to elucidate the genetic control of rebaudioside D synthesis from rebaudioside A. DLI influenced both glycoside concentration and relative proportion in a glycoside-specific manner. Using traditional breeding, populations were created via controlled crosses where parents varied in the percentage of rebaudioside D calculated from the total of rebaudiosides A and D. The production of rebaudioside D appears to be regulated by a single dominant gene controlling the presence/absence of the precursor compound, rebaudioside A. Some of the individual populations in this study exhibited correlations unique to each population regarding traits of interest, demonstrating the variability in stevia. Future breeding efforts could harness this variability in addition to knowledge of precursor glycoside content as a resource to improve future stevia lines.

Book Description :

The publication aims to familiarize students of public policy with the precautionary principle, which plays a vital role in the European Union’s approach toward regulating risks. The precautionary principle contends that policy makers should refrain from actions having a suspected risk of causing harm to the public and/or the environment. However, the precautionary principle only provides guidance to policy makers but does not prescribe specific policy responses. Therefore, there should be variation in the way the principle is applied. Furthermore, precautionary measures are, in principle, of a provisional nature, suggesting that they are likely to be subject to changes over time. This book is thus interested in shedding light on how the precautionary principle is put into practice and to what extent precautionary measures become modified. Empirically, it focuses on how the EU has regulated the use of growth hormones in meat production, the cultivation of genetically modified corn and the use of Stevia-based sweeteners in foods and beverages. The main theoretical argument advanced by this study is that the way in which the original regulatory standards were formulated affects whether and how they are changed. By placing particular emphasis on the relevance of scientific evidence for the (re-)definition of precautionary measures, the book is expected to appeal to both academics and practitioners.

Book Description :

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
