Comparative Studies on the Production of Glucose and High Fructose Syrup from Tuber Starches
نویسندگان
چکیده
Glucose and high fructose syrup (HFS) are made extensively from corn starch and the high cost of production demands the lookout for alternative starches as raw material. The present study was to compare the potential of tuber starches such as arrowroot, cassava, Curcuma, Dioscorea, sweet potato and Xanthosoma with corn starch for HFS production. The process consisted of liquefaction followed by saccharification and isomerization using three enzymes such as Liquezyme, Dextrozyme and Sweetzyme respectively. High performance liquid chromatographic (HPLC) profile showed that the starch conversion to glucose for the starches was equivalent or superior to that for corn starch. Sugar profile of the saccharified slurry had a composition of 98.28 to 98.84% glucose, maltose (1.03 to 1.69%) and maltotriose (0.03 to 0.10%) for arrowroot, Curcuma and cassava, while a lower range of glucose (94.76-97.28%) and higher range of maltose and maltotriose (2.0-4.3% and 0.49-0.75% respectively) for the other starches. Percentage conversion to fructose as well as fructose yield (g/100g starch) was the highest for arrowroot and Curcuma starches. Tuber starches offer promise as substitute for corn starch in the production of glucose and high fructose syrup.

Optimization of HFDS Production from Date Syrup (RESEARCH NOTE)
Fructose is utilized as a common sweetener in many food industries. Today, a large amount of HFCS (high fructose corn syrup, an equilibrium mixture of glucose and fructose) is produced by glucose isomerase, immobilized enzymes from corn starch. There are a lot of date palms in Iran. Date is a favorable source of carbohydrates, and a suitable source for HFDS (high fructose date syrup) production...
متن کاملCentral and Metabolic Effects of High Fructose Consumption: Evidence from Animal and Human Studies
Fructose consumption has increased dramatically in the last 40 years, and its role in the pathogenesis of the metabolic syndrome has been implicated by many studies. It is most often encountered in the diet as sucrose (glucose and fructose) or high-fructose corn syrup (55% fructose). At high levels, dietary exposure to fructose triggers a series of metabolic changes originating in the liver, le...

High fructose corn syrup (HFCS) is commonly found in soft drinks and juice beverages, as well as in many pre-packaged foods such as breakfast cereals, baked goods and dairy desserts. Historically, sucrose (table sugar) was primarily added to processed foods and beverages as the sweetening agent. In recent years, the use of HFCS has significantly increased in popularity due to its sweetness, abi...

Hydroxy Methyl Furfural (HMF) is a compound that is formed as a result of heat treatment and long storage of sugar products such as invert sugar and according to codex standards its limit in foods is 40 ppm. Fructose syrup 55% is a transparent liquid with a sweet taste and has no off-flavor and has similar sweetness and functional properties to sucrose. Various studies show that due to the prod...
