Abstract: A method is disclosed for preparing and using buffered aqueous solutions of carboxylic acids and metal salts of carboxylic acids. Such solutions are useful as mold inhibitors in bread, cakes, and animal feeds. Buffered aqueous solutions of about 40 to 80 percent of compounds of carboxylic acids and carboxylic acid metal salts, such as sodium diacetate, sodium dipropionate, sodium dibutyrate or sodium dibenzoate have been found to have a reduced corrosive nature to metals and alloys used to contain, transport, and apply these solutions, thereby permitting the use of these metals and alloys in existing and new facilities.
Abstract: Microbiologically stable foods which are oil-in-water emulsions usually kept at freezer temperature, but which can be maintained at room temperature and refrigerator temperature for an extended period of time, are prepared by controlling their sugar/fat content.These foods are of intermediate-moisture content and have sufficient solutes, generally sugars, to provide a bacteriostatic effect. The sugars used are predominantly of low molecular weight to additionally provide for a significant freezing point depression. A substantial amount of fructose, dextrose or a combination thereof is preferred for its resistance to crystallization which would cause apparent hardness at low temperatures. Finally, the product can more readily be maintained soft at freezer and room temperature if its fat content is at least in part unsaturated.

Abstract: The object of the invention is to provide an improved proteinaceous food product and a process for preparing it.The current commercial production of proteinaceous food products often employs the use of reducing sugars under conditions which result in the loss of protein quality due to the Maillard reaction. The present invention improves upon these food products and provides a process for stabilizing the protein quality of them.According to the invention, an effective amount of a non-essential free amino acid is incorporated into the food composition to save the protein quality from degradation. A preferred group of products are intermediate moisture products, particularly pet foods, which contain reducing sugars such as corn syrup and high fructose corn syrup to serve as water binders. The preferred non-essential amino acid additive according to the present invention is glycine and its soluble salts.
Abstract: Horticultural crops may be stored in an acidic aqueous liquor at a temperature not exceeding about room temperature wherein the pH of the liquor is sufficiently low and the storage conditions are adequately starved of molecular oxygen to retard spoilage of the stored product. Following termination of the storage, the stored product is preferably at least partially neutralized at a temperature of between about 40.degree. and 60.degree. F. with a neutralizing agent to raise the pH of the stored product. When green horticultural crops are thus stored and thereafter boiled, a strong green coloration is produced and green pigments can be separated by solvent extraction.

Abstract: Loss of texture in vegetable and fruit material caused by heating such material in connection with the preservation thereof can be minimized by contacting the fresh vegetable and fruit material with certain organic compounds for a short period of time and then removing the organic compound by rinsing the material with water or a water-based medium prior to heating the vegetable and fruit material.
Abstract: Valuable products are obtained from Theobroma fruits by preferably removing the peels from said fruits, opening the fruits, separating the seeds from the preferably peeled parenchymatous part of the fruits, and immediately thereafter fermenting the seeds and processing said parenchymatous part. Preferably the fruits are pretreated, for instance, with an alkaline solution and, after peeling, are neutralized, or they are pretreated with a preserving agent. The parenchymatous part of the fruits is expressed to yield the fruit flesh juice containing a hydrocolloid which has proved to be a valuable emulsifying, thickening, stabilizing, suspending agent and protective colloid. The expressed Theobroma fruit flesh is converted into a nutritious animal feed, especially for small animals. Thus the Theobroma fruits are substantially completely utilized.
Abstract: A system for pressure infiltration of liquid through the skin of fresh produce. The produce is subjected to vacuum pressure, and then coated with the liquid without submersion while continuing to subject the produce to the vacuum pressure. The application of liquid is continued as the vacuum pressure is progressively released to return the pressure surrounding the produce to atmospheric conditions, thereby causing the liquid to be forced through the produce skin surfaces due to the increase in exterior pressure about it. The coating apparatus is a combination of yieldable support rollers and an overhead spray. The rollers are partially immersed in a liquid bath from which liquid is recirculated to the spray nozzles.

Abstract: The invention relates to the long term stabilization of proteinaceous food products both for human and for animal consumption, having a moisture content exceeding 50% and preserved against microbiological spoilage by a pH value of 4.5 or below. The long term stabilization of such products is enhanced by the presence of viable homofermentative acid producing organisms, notably lactic bacteria, together with available fermentable carbohydrate. In the preferred process the pH value of a proteinaceous product is reduced to a value in the range 5.0 to 4.0 and fermentation of the bacteria is then brought about, whereby the pH value of the product attains a final value not exceeding 4.5, if necessary with a lowering of pH value by the action of the bacteria. In preferred embodiments of the process a food grade acid is added to reduce the pH of the product to the range 4.5 to 4.0 and the final pH value of the product lies in the range 4.3 to 3.8.
