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: A low-molecular weight peptide composition mainly based on dipeptides and tripeptides is produced by dispersing protein raw material from any suitable source in water at a concentration of 5 to 20 w/v %, adjusting the pH of the dispersion to 1 to 4 with an acid, adding at least two acid proteases to the dispersion, and permitting enzymatic proteolysis to take place for a desired period of time at a suitable temperature while supressing the formation of free amino acids. Also provided is a nutrient agent comprising the thus produced low-molecular weight peptide composition mainly based on dipeptides and tripeptides wherein the contents of free amino acids and those peptides having a molecular weight of at least 700 are individually 20% by weight or less. The nutrient agent is useful in medical treatment.

Abstract: A biologically pure culture of a bacterium of the genus Aquaspirillum, designated MS-1, has been found to contain chains (so-called magnetosomes) of single domain magnetite particles. The magnetite particles are roughly cubic and are about 500 .ANG. on a side. Each of the chains contains approximately 20 magnetite particles. These magnetite particles can be recovered from the bacterium and usefully employed in magnetic recording devices and the like. The biologically pure culture of the magnetic bacterium may be grown in a low oxygen environment and on a nutrient medium containing ferric quinate.

Abstract: Hollow fiber reactors for growing microbial cells. Isotropic hollow fibers are supported in a housing inoculated with cells. Nutrient medium passing through the lumen undergoes a pressure drop resulting in radial convective flow: the nutrient medium flows outwardly from the lumen into the surrounding area adjacent the entry port and fluid surrounding the hollow fiber flows into the lumen adjacent the exit port. With the efficient distribution of nutrients and removal of product, high cell densities are achieved providing for high product yields per unit reactor volume.

Abstract: This invention relates to a process for preparing a dehydrated, readily reconstitutable (i.e. "instant") baby cereal porridge product from a reduced-viscosity, gelatinized, cereal flour-water mixture. The reduction in viscosity of the gelatinized cereal flour-water mixture is achieved by a method in which a cereal flour-water slurry having flour solids content in the range 14% to 30% inclusive, is gelatinized and then subjected to a mechanical shearing action. In preferred embodiments one of the cereal flour ingredients in the slurry is oat flour.

Abstract: A powder-form foaming creamer suitable for use in beverages is prepared by spray-drying a mixture containing a non-dairy fat, a non-dairy carbohydrate and a proteinaceous foam stabilizer. In the spray-drying step, the mixture is atomized by forcing it through a narrow orifice under a high pressure. The dried powder withstands severe handling and retains the ability to produce a foam in the final beverage.

Abstract: A process for treating cereal grains and particularly oats, to separate the endosperm from the remainder of the kernel without dry milling. The grains are soaked in an aqueous medium having a pH of 3.0-7.0 at a temperature in the range 40.degree.-70.degree. C. for sufficient time to absorb at least an equal weight of the liquid medium. The conditions are such that the endosperm portion of the grain liquefies, as opposed to softens. The grain may be crushed in a variety of ways to split the husk and release the liquid endosperm contents which are then dispersed in water. The endosperm solids can be recovered from dispersion, following a screening step to separate the husks by drying to yield a substantially white, lower fiber whole endosperm flour product. Alternatively, the dispersion may be sedimented and/or centrifuged to produce a wet solids fraction and a soluble fraction, each of which can be subsequently recovered in dry form.
