大豆低聚糖胀气现象观察 总被引:4,自引:0,他引:4
本文将大豆低聚糖、改性大豆低聚糖、代聚果糖选择3种剂量高、中、低,分别进行小白鼠试验,观察3种低聚糖的胀气现象。试验结果表明:改性大豆低聚糖无胀气现象;低聚果糖在给人实际用量30倍剂量下有轻度的胀气现象;大豆低聚糖的情况与代聚果糖相似,但胀气作用较低聚果糖轻。 相似文献

Composition‐Based Prediction of Temperature‐Dependent Thermophysical Food Properties: Reevaluating Component Groups and Prediction Models 下载免费PDF全文
Prediction of temperature‐dependent thermophysical properties (thermal conductivity, density, specific heat, and thermal diffusivity) is an important component of process design for food manufacturing. Current models for prediction of thermophysical properties of foods are based on the composition, specifically, fat, carbohydrate, protein, fiber, water, and ash contents, all of which change with temperature. The objectives of this investigation were to reevaluate and improve the prediction expressions for thermophysical properties. Previously published data were analyzed over the temperature range from 10 to 150 °C. These data were analyzed to create a series of relationships between the thermophysical properties and temperature for each food component, as well as to identify the dependence of the thermophysical properties on more specific structural properties of the fats, carbohydrates, and proteins. Results from this investigation revealed that the relationships between the thermophysical properties of the major constituents of foods and temperature can be statistically described by linear expressions, in contrast to the current polynomial models. Links between variability in thermophysical properties and structural properties were observed. Relationships for several thermophysical properties based on more specific constituents have been identified. Distinctions between simple sugars (fructose, glucose, and lactose) and complex carbohydrates (starch, pectin, and cellulose) have been proposed. The relationships between the thermophysical properties and proteins revealed a potential correlation with the molecular weight of the protein. The significance of relating variability in constituent thermophysical properties with structural properties––such as molecular mass––could significantly improve composition‐based prediction models and, consequently, the effectiveness of process design. 相似文献

A brief summary of the structure of keratin fibres is followed by a review of their mechanical and allied properties. Among these properties are tensile stress–strain properties, stress relaxation, and creep, and torsional stress–strain properties and stress relaxation. The mechanism of supercontraction, properties of set fibres and disulphide-reduced fibres, and thermal transitions in keratin are also discussed. Finally, the various theoretical attempts that have been made to explain these properties are critically reviewed. 相似文献

物理作用力对κ-卡拉胶凝胶体质构特性影响的研究 总被引:1,自引:0,他引:1
研究了不同的盐类和有机试剂对κ 卡拉胶凝胶体质构特性的影响。结果表明 ,NaCl和NaSCN对凝胶特性的影响显著不同 ,随着NaCl浓度的增加 ,卡拉胶的硬度和破裂强度逐渐增加但凝胶体的其他特性即下降 ;NaSCN在低浓度时 (≤ 0 1mol/L)显著增加了凝胶体的硬度和破裂强度 ,而其他特性也下降。随着NaSCN浓度的增加 (>0 1mol/L) ,凝胶体的所有特性都下降 ;添加 0 1mol/L的KCl和KSCN极大的提高了凝胶体的质构特性。KCl和KSCN对凝胶体质构特性的影响趋势相似 ,但KCl的影响更大。氢键也是κ 卡拉胶形成凝胶的主要作用力 相似文献
