AN ACCU-CHEK PERFORMA DIABETIC biosensor was examined for use as a quantification method for glucose and sucrose within a sugarcane juice medium. The motivation for this study was the need for a fast, inexpensive and reliable primary method for sucrose determination. This proof of concept study obtained promising results, encouraging further development of this project. Calibration curves were ...

Bioethanol has been introduced in large scale in Brazil, the US and some European countries and is projected to be one of the dominating renewable biofuels in the transportation sector within the coming 20 years. At present bioethanol is produced almost solely from either sugar – or starch-based raw materials (e.g, cane sugar, corn, wheat etc) often called first generation (1G) bioethanol. Howe...

Abstract Background Sugarcane is an essential crop for sugar and ethanol production. Immediate processing of sugarcane necessary after harvested because rapid sucrose losses deterioration stalks. This study was conducted to fill the knowledge gap regarding exploration fungal communities in deteriorating sugarcane. Experiments were performed on simulating production at 30 °C 40 0, 12, 60 h harve...

Accepted: 21/03/2014 Abstract Enzymes are an integral component of modern fruit juice manufacturing processes. Their main functions are to: increase extraction of juice from raw material, increase processing efficiency (pressing, solid settling or removal), and generate a final product that is clear and visually attractive. Juice extraction can be done by using various mechanical processes, whi...

Ultra-high pressure homogenisation (UHPH) is a recently developed technology and is still under study to evaluate its effect on different aspects of its application to food products. The aim of this research work was to evaluate the effect of UHPH treatments on quality characteristics of apple juice such as antioxidant capacity, polyphenol composition, vitamin C and provitamin A contents, in co...

Through a joint SASEX/CIRAD, project the effect of Eldana saccharina Walker (Lepidoptera: Pyralidae) damage on stalk yield components was studied in fields at the SASEX farms at Gingindlovu and Empangeni. The formal experiment design consisted of randomised plots to compare natural infestation, artificial infestation and chemical treatments. Damaged stalks from infested plots had lower sucrose,...

Dextran is one of the by-products of sour-storage rot of sugar cane (Egan, 1971). The presence of dextran in cane juice entering the mill has many deleterious effects on raw sugar processing and quality (Foster, 1969a,b; Henderson, 1971; Foster and Wright, 1969; Leonard and Richards, 1969). Hence, the removal of the polysaccharide from juice may alleviate these effects. Physico-chemical methods...

In 1941 Wulzen and Bahrs (1) reported a characteristic muscular stiffness at the wrist among guinea pigs on a skim milk diet, which progressed in intensity over a period of months. Autopsies of deficient animals revealed extensive calcification throughout the muscles and internal organs. Raw cream fed by mouth was found to alleviate the wrist stiffness within a few days, although disappearance ...
