Fructose: back to the future?
nutrient metabolic endocrine responses diabetes downstream cardiometabolic complications
2018/11/15
Sugars have emerged as the dominant nutrient of concern. Attention has focused squarely on the fructose moiety as the main bad actor in sugars due to its unique set of biochemical, metabolic, and endo...
Chronic fructose substitution for glucose or sucrose in food or beverages has little effect on fasting blood glucose, insulin, or triglycerides: a systematic review and meta-analysis
sugar replacement fructose glucose sucrose insulin triglycerides diabetes body weight
2018/11/15
Background: Conflicting evidence exists on the role of long-term fructose consumption on health. No systematic review has addressed the effect of isoenergetic fructose replacement of other sugars and ...
How sweet is acute exercise after pure fructose ingestion?
sweet exercise pure fructose ingestion
2018/11/27
The controversy continues as to whether the consumption of sugar-sweetened beverages and added sugars (especially fructose in the form of sucrose and high-fructose corn syrup) poses a risk of the deve...
“This is the most robust study showing there is a difference between high-fructose corn syrup and table sugar at human-relevant doses,” says biology professor Wayne Potts, senior author of a new study...
Effect of replacing sucrose with fructose on the physico-chemical sensory characteristics of kinnow candy

2014/2/27
Antimicrobial effects of various fatty acids and their esters have been extensively studied. Esters with saccharides (glucose, sucrose) have been found to have a broad spectrum of microbicidal activit...
针对国内结晶果糖生产中存在的问题，对果糖结晶工艺进行改进，并优化工艺参数。研究发现，向高果糖浆中加入表面活性剂Span 60，可使结晶果糖的变异系数降低51.5%，提高果糖晶体均匀性；在进行结晶前，用高效糖化酶降解低聚糖，可将果糖浆粘度降低26.2%。酶解最佳工艺条件为：酶解时间20h，强效糖化酶用量为600mg/kg，pH值4.0，酶解温度55℃。优化的果糖结晶工艺条件为：晶种添加量为2%，初始...
高压CO2—水混合体系水解菊粉制备果糖工艺（High Pressure CO2?—Water System for Inulin Hydrolysis to Produce Fructose）
菊粉 高压CO2—水混合体系 水解
2009/9/11
为了解决利用传统酸水解菊粉制备果糖工艺的缺点，采用高压CO2—水混合体系代替普通酸性水溶液，研究了菊粉在该体系中的水解情况，考察了CO2压力、反应温度和反应时间对菊粉水解制备果糖的影响。结果表明，菊粉的水解度随CO2压力的增大、反应时间的延长而增大，随反应温度的升高先增大而后下降。在反应压力为20?MPa、反应温度为70℃、反应时间为3h的条件下，菊粉的水解度达94.9％，说明菊粉在高压CO2—水...

The apparent distribution coefficients, Kapp, of glucose and fructose onto cation-exchange resins in calcium-ion form with different divinylbenzene (DVB) contents were observed over a wide concentrati...
Formation of Pyrazines in Aqueous Maltose/Glucose/Fructose-Glutamine Model Systems upon Heating at below 100°C
sugar glutamine non-enzymatic browning reaction
2009/6/18
Pyrazines generated from aqueous sugar-glutamine model systems heated at 90°C were investigated quantitatively. To determine trace levels of pyrazines in aqueous matrices, an efficient method using so...
Effects of Fructose-Isoflavone Diet on Plasma Isoflavonoids and Cecal Enzyme Activity in Mice

The effects of trehalose, glucose, fructose, and sucrose on the gelatinisation and retrogradation properties of corn (CS) and tapioca (TS) starches were studied with differential scanning calorimetry ...
Conversion from 1,5-Anhydro-D-Fructose into Functional Compound, Ascopyrone P by Heating
1,5-anhydro-D-fructose ascopyrone P antioxidant
2008/4/20
Radical scavenger activity of the heated, aqueous solution of 1,5-anhydro-D-fructose was higher than that of non-heated one. The reason was ascopyrone P, which had 500-fold stronger radical-scavenger ...
