LIQUID GLUCOSE FROM RICE
[CODE NO.4243]
Glucose is a commercially import ant product widely used by the food and pharmaceutical industries. In general, glucose is used in the food industry as a partial or complete substitute for sucrose. Glucose is the common name for the syrup which is used in large quantities in fruit canning, confectioneries, jams, jellies, preserves, ice cream, bakery products, pharmaceuticals, beverages and alcoholic fermentation. The functional purpose of glucose in the confectionery industry is to prevent crystallization of the sucrose while in the bakery products industry it is to supply fermentable carbohydrates. In the icecream and fruitpreserves, it used to increase the solidswithout causing an undue increase in the total sweetness. In pharmaceutical industry, glucose is used as a precursor to make vitamin C in the Reichstein process, to make citric acid, gluconic acid, polylactic acid and sorbitol. Currently, glucose is utilized as an intermediate raw material for bioethanol production.
Commonly, glucose is prepared commercially via the enzymatic hydrolysis of starchinstead of acid hydrolysis. Many crops can be used as the source of the initial starch. Maize, rice, wheat, potato, cassava, arrowroot and sago are all used in various parts of the world. Nevertheless, using the starch needs to compete with their primary use as food crops. Due to the abundant of nonfood energy crops like cellulosic material, they are use to reduce the utilization of starch as raw material for production of glucose. Cellulosic materials including agricultural, agroindustrial and forestry lignocellulosic residues have potential as cheap and renewable feedstocks for large scale production of fuels and chemicals. Currently, bioprocessing of lignocellulosics is focused on enzymatic hydrolysis of the cellulose fraction to glucose, followed by fermentation to fuelgrade ethanol. However, enzymatic hydrolysis of cellulosic materials to produce fermentable sugars has also enormous potential in meeting global food and energy demand via biological route.
In lignocellulosic materials cellulose is physically associated with hemicellulose and physically and chemically associated with lignin. The presence of these two fractions is reported to make the access of cellulase enzymes to cellulose difficult, thus reducing the efficiency of the hydrolysis. There are several kinds of pretreatment able to disrupt the lignocellulosic structure for increasing the efficiency of the hydrolysis which have been investigated but are not within the scope of this study. However, the effect of temperature and pH are also significant in cellulose hydrolysis which will be stud ying in this study. The temperature and pH influence the efficiency of cellulase to degrade the cellulose for producing glucose.
In order to produce glucose, cellulose is essential to break it down first.By using acid hydrolysis, conversion of cellulose to glucose only produces low glucose concentration because acid is no selectivity. Furthermore, by using acid causes the cost production of glucose is highdue to demand of neutralization after hydrolysis which can contribute to corrosion problem if there is no neutralization process. Other that, the need of high temperature during acid hydrolysis process also contribute s to the cost of production because high energy is consumed. Waste from acid hydrolysis also gives the bad effect to the environment which is using high concentration of acid can cause harmful to the environment. Therefore, the investigation attempted to determine the glucose production by using enzymatic hydrolysis process inorder to replace acid hydrolysis process.
Nevertheless by using enzymatic hydrolysis need highly specific and very sensitive. Their environmental condition such temperature and pH influence the activity of the enzymes in the system. Hence, the effect of temperature and pH is investigated to determine the maximum conditions of enzymatic hydrolysis process in glucose production.
Glucose is a simple monosaccharide sugar also known as grape sugar, blood sugar or corn sugar which is a very important carbohydrate in biology. The living cell uses it as a source of energy and metabolic intermediate. Glucose is one of the main products of photosynthesis and starts cellular respiration in both prokaryotes and eukaryotes. Glucose (C6H12O6) contains six carbon atoms, one of which is part of an aldehyde group (Figure). Therefore, glucose is an aldohexose. Glucose is commonly available in the form of a white powder or as a solid crystal, called dextrose. It can also be dissolved in water as an aqueous solution, glucose syrups.
Its solubility level is very high.
Glucose can be forms disaccharide when two of monosaccharide are linked together such sucrose, the combination of glucose with fructose. Sucrose is the most common sweetener in the modern, industrialized world, although it has been displaced in industrial food production by some other sweeteners such as glucose syrups or combinations of functional ingredients and high intensity sweeteners.
In lactose, another important disaccharide, glucose is joined to galactose (Figure ). It used as the predominant sugar in milk. For maltose, a product of starch digestion is glucose glucose disaccharide. Glucose also can be forms polysaccharides when the units (either mono or disaccharides) are repeated and joined together by glycosidic bonds like cellulose. Cellulose is yet a third polymer of the monosaccharide glucose.
