Stevia Extract

[Characteristics]

Stevia sugar features high sweetness and low calorie and its sweetness is 200 350  times of that  of cane sugar but its calorie is only 1/300 of that of cane sugar.

The component of stevia extract that gives it its sweetness is a mixture of various steviol glycosides. The components of sweetness in stevia leaves are stevioside, rebaudioside A, C, D, E and dulcoside A. Rebaudioside C, D, E and dulcoside A are small in quantity. The principal components are stevioside and rebaudioside A.

The quality of stevioside and rebaudiosideA is better than those of other components, which are commercially extracted and used in various applications.

The steviol glycosides present in stevia extract are referred to as “steviosides” or ¡°stevia extract¡±. Among these “steviosides”, the most common is Stevioside followed by RebaudiosideA. The Stevioside has a slight and pleasant herbal taste and the Rebaudioside-A has no herbal taste.

Although Rebaudioside C and dulcoside A are small in quantity in stevia extract, they are the major components giving bitter aftertaste.

[Function]

A large number of pharmaceutical tests have proved that stevia sugar has no side effects, carcinogens, and is safe for eating.

Compared with cane sugar, it can save 70% of the cost. With pure white color, pleasing taste and no peculiar smell, Stevia sugar is a new sugar source with broad perspective for development. Stevia rebaudianum sugar is the natural low hotsweet agent mostly similar to the flavor of cane sugar, approved to be used by State Ministry of Health and Ministry of Light Industry.

It is the third natural succedaneum of cane sugar and beet sugar with development and health care value, extracted from the leaves of the herbal vegetable of the composite family-stevia rebaudianum.

This short definition of stevia presentes its attributes and benefits. Safe for children (the product and the video); safe for adults.

Certainly not global warming though, perhaps, bovine flatulence.

Sprayable Antibacterial Film: A Nanosilver Composite
TEAM: Nathan Cloeter, Luis Correa, Benjamin Lee, Matt Reilly, Mercedes Valero

ABSTRACT: Recent studies suggest that cell phones are one of the surfaces with the most bacteria we encounter in our day, where it was shown that 1 in 6 cellphones are contaminated with fecal matter (Song). Silver nanoparticles have been shown to be highly efficient antibacterial nanoparticles, largely due to the oxidation and release of silver ions (Ferrer, Guo). Composite materials with antibacterial polymers and silver nanoparticles expand the applications of silver nanoparticles for antibacterial purposes, especially because they can be used as coatings for a variety of applications. These composites are beneficial because the nanoparticles can prevent bacterial growth while the polymer can prevent bacterial adhesion. This design takes advantage of the inherent antibacterial properties of chitosan, a polysaccharide extracted from shrimp shells, and the silver nanoparticles to produce a chitosan based polymeric coating with enhanced antibacterial properties. In the design, the properties of the sprayable solution, the nanoparticle formation kinetics and the film properties were studied. We also report on the results from the preliminary prototyping and antibacterial testing of films designed to be applied to the Aluminum back of the iPhone 5.
