High fructose corn syrup (HFCS) is a liquid alternative sweetener to sucrose that is made from corn, the “king of crops” using chemicals (caustic soda, hydrochloric acid) and enzymes ( -amylase and glucoamylase) to hydrolyze corn starch to corn syrup containing mostly glucose and a third enzyme (glucose isomerase) to isomerize glucose in corn syrup to fructose to yield HFCS products classified ...

Toxicity assessment of high fructose corn syrup-55: a repeated dose oral toxicity study in uterus and ovaries female rats

Our laboratory has investigated 2 hypotheses regarding the effects of fructose consumption: 1) the endocrine effects of fructose consumption favor a positive energy balance, and 2) fructose consumption promotes the development of an atherogenic lipid profile. In previous short- and long-term studies, we showed that consumption of fructose-sweetened beverages with 3 meals results in lower 24-h p...

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...

The pasting and gel textural properties of corn starch in syrup at different concentrations were investigated by Rapid Visco Analyzer (RVA) and Texture profile analysis (TPA) tests. The results showed that the pasting temperatures of corn starch greatly increased, especially at higher sugar concentration. Increasing concentration of syrup caused an increase in peak, trough and final viscosity o...

Fructose is a sugar present in sucrose, high-fructose corn syrup, honey, and fruits. Fructose intake has increased markedly in the last two centuries, primarily due to increased intake of added sugars. Increasing evidence suggests that the excessive intake of fructose may induce fatty liver, insulin resistance, dyslipidemia, hypertension, and kidney disease. These studies suggest that excessive...

Some commercial sweet sorghum syrups can be fraudulently or accidently adulterated with inexpensive sugar syrups, particularly high fructose corn syrup (HFCS) or corn syrup, and sold at a relatively low market price or even mis-branded. This undermines the economic stability of the current small-scale producers of food-grade sweet sorghum syrup as well as the developing large-scale bioproduct i...

Honey adulteration with sugar syrups is a widespread problem. Several types of syrups have been used in honey adulteration, and there is no available method that can simultaneously detect all of these adulterants. In this study, we generated a small-scale database containing the specific chromatographic and mass spectrometry information on sugar syrup markers and developed a simple, rapid, and ...

Carbonated and noncarbonated, sweetened blueberry flavored milks were evaluated by a trained panel. The effect of carbonation and sweetener type (sucrose, high fructose corn syrup, aspartame, and pear concentrate) on flavor properties was measured. Carbonation enhanced the sensory rating of overall flavor intensity, sweetness, and blueberry flavor. Sweetener type had a significant effect on the...

Arboreal environments pose many functional challenges for animal locomotion including fitting within narrow spaces, balancing on cylindrical surfaces, moving on inclines, and moving around branches that obstruct a straight path. Many species of snakes are arboreal and their elongate, flexible bodies appear well-suited to meet many of these demands, but the effects of arboreal habitat structure ...
