    • A method and apparatus for determining the stability of dispersions and emulsions accelerates the onset of significant particle agglomeration in a sample by stressing the sample by reducing the height of the interparticle potential energy barrier between the particles. This is achieved by adding one or more of three stress factors: changing the pH of the sample to reduce the surface charge on the particles; adding an adsorbing electrolyte so that ions of the appropriate charge are adsorbed onto the surfaces of the particles to reduce the net charge on the particles; and applying a monovalent, divalent, or trivalent salt to partially screen electrostatic repulsions between the charged particles. In a preferred embodiment, the increase in agglomeration is detected with single particle detection, such as SPOS, to generate a PSD from which a figure of merit is derived. Another embodiment detects turbidity or light scattering to generate a value X indicative of the extent of agglomeration.
    • 用于确定分散体和乳液的稳定性的方法和装置通过降低颗粒之间的颗粒间势能阻挡层的高度来加速样品的强度,加速了样品中显着的颗粒聚集的发生。 这通过添加三种应力因子中的一种或多种来实现:改变样品的pH以减少颗粒上的表面电荷; 添加吸附电解质使得适当电荷的离子被吸附到颗粒表面上以减少颗粒上的净电荷; 并施加一价,二价或三价盐以部分地屏蔽带电粒子之间的静电排斥。 在优选的实施方案中,通过单粒子检测(例如SPOS)检测聚集的增加以产生从其导出品质因数的PSD。 另一个实施方案检测浊度或光散射以产生指示聚集程度的值X.

    • Yeast-derived fiber has been demonstrated, as described herein, to effectively improve the serum lipid profile in humans, when provided as a dietary supplement, without some of the disadvantages known to accompany dietary supplementation with oat fiber or psyllium fiber. Described herein are dietary supplements comprising yeast fiber, e.g., &bgr;-glucan or glucomannan, and further comprising folic acid or a salt thereof, vitamin B6, vitamin B12, and vitamin E. The dietary supplements of the invention can further comprise fats, carbohydrates and proteins, for example, and other ingredients added to formulate a food product. Such food products can be in the form, for example, of solid or semi-solid foods, such as food bars, pudding, or spreads. By including folate and vitamin B6, the dietary supplement provides a second benefit of suppressing the level of homocysteine in the blood. A third benefit is provided by the anti-oxidant properties of vitamin E, particularly the effect of preserving low density lipoproteins from oxidation. Further embodiments of the invention are methods for improving the serum lipid profile in a human, methods for lowering risk of heart disease, and methods for improving cardiovascular health in a human, comprising administering to the human a dietary supplement of the invention.
    • 如本文所述,已经证明了酵母衍生的纤维,当作为膳食补充剂提供时,有效地改善了人类的血清脂质谱,而没有已知的与燕麦纤维或欧车前纤维的膳食补充剂相关的一些缺点。 本文描述的是包含酵母纤维例如β-葡聚糖或葡甘露聚糖并且还包含叶酸或其盐,维生素B6,维生素B12和维生素E的膳食补充剂。本发明的膳食补充剂还可以包含脂肪,碳水化合物和 蛋白质,以及其它添加成分配食品的成分。 这样的食品可以是例如固体或半固体食物,例如食物棒,布丁或散布物的形式。 通过包括叶酸和维生素B6,膳食补充剂提供了抑制血液中同型半胱氨酸水平的第二个好处。 维生素E的抗氧化性质,特别是保护低密度脂蛋白氧化的作用提供了第三个益处。 本发明的其它实施方案是用于改善人类血清脂质分布的方法,用于降低心脏病风险的方法,以及改善人类心血管健康的方法,包括向人类施用本发明的膳食补充剂。
