摘要:
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.
摘要:
A method for reducing the number lipid droplets having a diameter exceeding a preselected threshold in a nutritional emulsion has been developed. The method has the steps of passing the nutritional emulsion, under pressure, through a filter having a pore size smaller than the threshold. A filter having a mean pore size of about 1.2 .mu.m with a standard deviation of about 0.5 is sufficient to exclude lipid droplets having a diameter in excess of five .mu.m.
摘要:
A method of preparing TPN solutions, which is particularly well adaptable to computerized control, has been developed. These methods can assist the pharmacist or physician in the preparation of three-in-one TPN solutions containing lipid, dextrose and amino acids. The method includes a series of criteria for concentrations of lipid, dextrose, amino acids, and ions as well as eliminating the possibility of certain deleterious interactions.
摘要:
A new class of synthetic triglycerides, those having at least one short-chain (C.sub.2 -C.sub.5) fatty acid on a glycerol backbone, has been developed. These synthetic triglycerides (or structured lipids) are particularly useful in treating patients with intestinal problems.

Compositions useful in the treatment of dietary disorders, and as dietary additives to provide a source of fiber and of short chain fatty acids, to reduce the level of serum cholesterol and as bulking agents in humans and animals, as well as methods of use therefor are described. The compositions and methods are based on whole .beta.-glucans.
摘要:
A nutritional supplement is described comprising approximately from about 10 to about 75 grams carbohydrate; approximately from about 5 to about 50 grams protein; approximately from about 3 to about 30 grams fat; and therapeutic amount of antioxidant, for use in weight maintenance in individuals who will undergo major surgery to prevent or reduce postoperative complications.
摘要:
A nutritional supplement comprising approximately from about 5 to about 25 grams carbohydrate; approximately from about 1 to about 25 grams protein; and approximately from about 1 to about 10 grams fat, for use in treating low appetite that may result in weight loss, is described.
摘要:
A novel diabetic supplement bar which includes about 10-60% by weight simple carbohydrate, about 1-25% by weight protein, about 2-40% by weight lipid and about 1-60%, preferably about 5-35% by weight complex carbohydrate. This formulation is particularly useful for the treatment or prevention of nighttime hypoglycemia in diabetic patients who require insulin injections.
摘要:
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.
