5-Hydroxy-2-Methylfurfural from Sugar Beet Thick Juice: Kinetic and Modeling Studies

Evaluation of the fermentation of high gravity thick sugar beet juice worts for efficient bioethanol production

BACKGROUND Sugar beet and intermediates of sugar beet processing are considered to be very attractive feedstock for ethanol production due to their content of fermentable sugars. In particular, the processing of the intermediates into ethanol is considerably facilitated because it does not require pretreatment or enzymatic treatment in contrast to production from starch raw materials. Moreover,...

Efficient Dehydration of Fructose to 5-Hydroxy- methylfurfural Catalyzed by Heteropolyacid Salts

5-Hydroxymethylfurfural (5-HMF), which is derived from numerous industrial biomass resources, has attracted attention in recent years due to its potential as a building block. In this paper, a range of heteropolyacid salts had been investigated for the dehydration of fructose to 5-HMF. CePW12O40 demonstrated the best catalytic activity. Effects of fructose concentration, reaction temperature an...

Effect of Storage Temperature and Light on the Freeze-Dried Amino Acids from Sugar Beet and Sugar Cane Molasses

Molasses is a significant by-product of sugar beet or sugar cane refining industry. In this work, the effects of storage temperature and packaging on the contents of free amino acids (AAs) in sugar beet and sugar cane molasses after freeze drying were inquired. The effect of different variables such as, temperature (4 and 25˚C) and light (Metallized polypropylene container and Normal polypropyl...

The Effects of Chemical Purification on the Color of Thin and Thick Juices in Sugar Beet Factories

Background and Objectives: Recognizing the impurities of sugar beet and also comparing different methods of juice purification have shown that the chemical purification based on lime and carbon dioxide is really efficient and economic in the sugar industry. Factories have to control and improve purification stages to achieve clear juice with high chemical purity, low color, minimum hardness, su...
