A high quality soy protein concentrate (SPC) was produced by a process of enzyme treatment combined with ultrafiltration. Soy flour, the starting material, was enzymatically treated with commercial pectinases and diafiltered with a porous stainless steel ultrafiltration system. The resulting product had reduced levels of physic acid and nucleic acids due to contaminant phytase and nuclease activity in the pectinase enzymes. The functionality of the SPC was improved due to increased solubility compared to conventional soy isolates produced by acid precipitation. High performance liquid chromatography gel filtration profiles indicated that the proteins in the SPC remained intact. The SPC also had reduced flavor when compared to the original soy flour according to gas chromatography flavor profiles and sensory evaluation.

Soy proteins and methods for their production

A hollow shaft hunting arrow carries a small volume of liquified carbon dioxide which is released by flash expansion upon penetration into the thorax of a game animal. The thorax is pressurized with carbon dioxide gas at sub-zero temperature to cause collapse of the lungs and fibrillation of the heart, so that the animal can be harvested on the spot, thus avoiding escape and uncertain recovery. The liquified carbon dioxide is carried in an internal reservoir and is released by flash expansion upon opening actuation of a valve closure member. The arrowhead includes a freely movable center core which is attached to an actuator shaft that is engagable with a release valve. The release valve is actuated by either piercing a metallic membrane, fracturing a glass or ceramic lens or unseating the ball closure of a ball valve assembly. A small amount of fluorescent dye is introduced into the liquified carbon dioxide which provides a marker in the blood trail left by a wounded animal which will fluoresce or glow when exposed to ultraviolet light.

A method for debittering and reducing the allergenic reactivity of protein hydrolysates is disclosed, which method includes the providing of an aqueous solution of a protein hydrolysate, feeding the solution into a bed of siloxane, and collecting a first portion of the solution exiting from the bed. The first portion contains either a non-bitter or bitter fraction. A second portion of the solution exiting from the bed can be collected which contains the opposite tasting fraction of the hydrolysate. Preferably the siloxane is selected from the group comprising octa-siloxane and octadecyl-siloxane. Preferably the hydrolysate has a molecular weight of less than 10,000, and is derived from the group of hydrolysates comprising casein, whey and soy. Additionally, the bed preferably is of a depth of between 2 to 4 times the bed diameter. A more hypoallergenic protein hydrolysate product produced in accordance with the method of the invention is also disclosed.

The present invention is directed to a process for extracting pigments, namely carotenoids, from plant material. The process includes the step of combining shredded plant material with an enzyme. The enzyme breaks down the plants cellular walls releasing the carotenoids contained within the plant cells. The enzyme added to the plant material can be pectinase, cellulase, hemicellulase, or mixtures thereof.

A process and apparatus for reducing the volume and mass of solid waste (A) by initially subjecting the solid waste to a digestive enzymatic solution (20) agitated by fluid jets (28) under conditions which convert substrate (12) into a liquid waste which is discharged through a conventional sewage system (30). Non-biodegradable plastic shells (10) may be collected in a strainer basket (24) to be removed for further solid waste treatment such as shredding and the like.

A process is disclosed for chemically converting a substrate into its reaction products and immediately thereafter physically separating the reaction products in a continuous operation. The process is carried out with a bioreactor having an ultrafiltration membrane containing an immobilized chemical agent which is preferably an enzyme. The bioreactor is prepared by securing an ultrafiltration membrane to an inside wall of a porous tubular support and chemically bonding an enzyme to an inner surface of the membrane. The enzyme is preferably bonded to the membrane by chelation and the membrane may be a polymeric membrane or a metal oxide membrane. To convert a substrate, a substrate-containing feed stream is preferably flowed tangentially along the inner surface of the membrane containing the immobilized enzyme. Sufficiently small reaction products filter through pores of the membrane and larger reaction products are retained by the membrane. In a preferred embodiment, contacting of fresh fruit juice with pectinase immobilized on the membrane results in pectinase treatment or the juice and immediate extraction and clarification of the juice. In another embodiment, the enzyme immobilized is glucoamylase and corn dextrins are converted to reducing sugars.

Disclosed are ultrafiltration processes for the enrichment and concentration of selected proteins from protein conaining fluids. Illustratively, IgG is concentrated from whey by means of multiple ultrafiltration 'passes', using a metallic oxide ultrafiltration membrane, which are characterized by differing pH's.

An improved process for obtaining juice from fruit. The fruit is processed to provide a pumpable fluid puree of fruit and juice which is pumped at pressures in a range of from about 100 to about 1000 pounds per square inch in a single pass through a rigid porous tubular housing having a diameter of from about 5/8 inch to about six inches and having a food grade ultrafiltration membrane deposited on inside surfaces of same. Initial permeability (P) of the membrane to water is from about 1 to about 15 according to the formula ##EQU1## where permeate flux is gallons of water passing through a square foot of membrane area per day and pressure is measured in pounds per square inch. Exit pressure from the housing is maintained in a range of from about 50 to about 100 pounds per square inch. Clear, commercially sterile juice with the taste and aroma of fresh fruit can be obtained at juice yields of at least about 78%.
