Abstract: This invention relates to a process for concentrating aqueous solutions having temperature-sensitive components. More particularly, this invention relates to an improved process for concentrating aqueous solutions having temperature-sensitive components which comprises the steps of:(a) subjecting the aqueous solution to an ultrafiltration procedure to provide a permeate solution and a residual solution; and(b) subjecting the permeate solution from step (a) to freezing and removing ice crystals formed thereby.

Abstract: This invention is concerned with a low bulk density lyophilized pharmaceutical parenteral dosage unit of Sodium Piperacillin and method of making same.

Abstract: A process for the manufacture of alcoholic beverages of low alcohol content is disclosed, wherein a standard alcoholic beverage is chilled to form crystals, which are then consolidated into a substantially solid mass. The mass is then recovered, thawed, and optionally blended with either the unfrozen portion of the starting beverage or with a further quantity of the standard beverage itself to produce a low alcohol counterpart which retains substantially all of the flavor and taste of the standard beverage.

Abstract: A process for preparing a natural citrus fruit juice concentrate prepared from natural citrus fruit ingredients is disclosed. The fruit juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds. This fruit juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice.The fruit juice concentrate is prepared by separating natural citrus fruit juice into a particulate solids portion (such as pectin or pulp) and a serum portion. The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water. The concentration step can be accomplished by freeze concentration or by sublimation concentration. When sublimation concentration is used, the particulate solids do not have to be separated from the serum. Substantially 100% of the non-volatile solids are retained. Moreover, the product is substantially free of oxidative degradation products.

Abstract: The outer waxy, cutin-containing layer is removed from papaya by freeze-drying the fruit to separate the layer from the underlying fruit and then mechanically removing the so-separated layer.

Abstract: A natural orange juice concentrate prepared from natural orange compounds is disclosed. The orange juice concentrate has at least 35% solids including pulp, non-volatile compounds, pectin and volatile compounds. This orange juice concentrate has at least 65% of the aroma and flavor volatile compounds of the natural juice. The aroma and flavor volatile compounds comprise a low boiling fraction and a higher boiling fraction in a ratio of at least 4:1. The ethyl butyrate level is at least 0.1% of the total volatile compounds, the proportion of ethyl butyrate to limonene being in the range of 0.0015:1 to about 0.6:1.The orange juice concentrate is prepared by separating natural orange juice into a pulp portion and a serum portion. The serum portion which comprises 7% to 20% solids and from 80% to 93% water is concentrated by removing essentially pure water. The concentration step can be accomplished by freeze concentration or by sublimation concentration.

Abstract: A process of reducing the amount of cholesterol in egg-yolk which comprises reducing the pH of fresh wet egg-yolk to destabilize the emulsion, treating the destabilized emulsion with an edible oil to form a fine dispersion and centrifuging the dispersion to separate the egg-yolk phase from the oil-phase.

Abstract: A concentrated natural vinegar with an excellent natural flavor is prepared by treating a product obtained by freeze concentration of natural vinegar with a greater amount of alcohol obtained by natural fermentation than is already present in the natural vinegar due to its preparation. When contacting the mixture of freeze concentrated natural vinegar and alcohol with an acidic ion exchanger, acetic acid esters are prepared which correspond to acetic acid esters extracted from natural products.

Abstract: A thermally processable imaging element and method are disclosed, wherein dimensional changes after thermal processing for about 5 seconds at a temperature of about 125.degree. C., do not exceed .+-.0.03%. The imaging element features an amine-generating and an amine-responsive composition. The method features preheating the element prior to exposure to dimensionally stabilize it.

Abstract: Dry chip-like discs of provisions or fine foods and a process for producing such discs. Raw food materials containing builder materials and soluble ingredients are converted into an essentially homogeneous pulp, and are brought into a composition which, as regards taste, is ready to be consumed. This pulp, having a consistency from flowable to pasty, is shaped into discs having a thickness of from 1 to 10 mm and is carefully dried, thereby substantially maintaining the builder structure and the thickness of the layer of the disc. The discs so produced are suitable for immediate consumption without previous mixing with liquids, and are converted back into a pulp by saliva in the mouth, the presence of the discs in the mouth stimulating the production of saliva.

Abstract: A process for the concentration of aqueous solutions which in addition to non-volatile components contain alcohol and small amounts of volatile aroma components. First the alcohol and the volatile aroma components are for the greater part separated from the solution by distillation, and condensed; subsequently the remaining aqueous solution is concentrated by freeze concentration; and finally the concentrate thus produced is mixed with said condensate.

Abstract: The preparation comprises the steps of freezing the water of an infusion into ice flakes or crystals, draining the resulting sherbet, injecting it under low pressure into a centrifuge, centrifuge draining it and forcing it out of the 'fuge under increased pressure. During each step, the liquid is collected. Finally, the liquid is thermally concentrated into a powder.
