Abstract: The mixed lymphocyte reaction in tissue culture is used to detect the tumor induced autoimmune reaction which has been found to be characteristic of lymphoid malignancies. Lymphocytes from blood, spleen, and lymph nodes are employed in combinations of two. A mixed lymphocyte reaction from any one of the three possible combinations is indicative of the presence of a lymphoid malignancy.

Abstract: The present invention encompasses a bulking agent suitable for incorporating into formulated foods. The bulking agent of the present invention is prepared by condensation of glucose and sorbitol in the presence of an acid-ion exchange resin. The bulking agent of the present invention provides the functions and bulk of about the same weight of sucrose when incorporated into formulated foods. The bulking agent of the present invention is most advantageously used in conjunction with high intensity sweeteners.

Abstract: A method of removing bitter flavor and pea flavor from a pea flour for addition to food systems comprising the steps of contacting the flour with steam for a time duration sufficient to debitter the pea flavor and cause the steam to take up volatiles and then leading off the steam and volatiles before a substantial cooked pea flavor develops.

Abstract: The enhancement of foodstuffs is effected by the addition of a small but effective flavor - modifying amount of a compound having the general formula ##STR1## wherein R.sub.1 is hydrogen, an alkyl group or a phenyl group, R.sub.2 is hydrogen, an alkyl group or an acyl group and n is 0, 1 or 2.

Abstract: Saccharification of 10-20% solid content dextrin solutions for 15-75 hours at amyloglucosidase enzyme dosage levels of 0.3-1.0 AG u/g of solids results in glucose syrups with purity levels exceeding 98%.Glucose purity levels in excess of 98.5% can be achieved if the dextrin solution is formed by enzymatic liquefaction of starch, and saccharification is carried out for 15-25 hours with 0.4-0.8 AG u/g.

Abstract: The present invention relates to improvements in the sandwich technique for the determination of a component of an antigen-antibody reaction in a liquid sample to be tested, utilizing as reagents (a) one component of said reaction bound to the surface of a water-insoluble, water-insuspensible, solid carrier, and (b) a component having the same immunological properties covalently linked to an enzyme. The liquid sample is contacted and incubated with the reagent(s) to form a reaction mixture, the enzyme activity of either the liquid or solid phase of which is a measure of the presence and quantity of the component to be determined. The method is especially useful for diagnostic testing for hepatitis or rubella antibodies.

Abstract: The invention provides fat blends e.g. suitable for preparing margarines containing high porportions of palm-based fats, partly in co-randomised form, the fat blends having a ratio of PUP:PPU triglycerides of less than 2.8, the Sa.sub.3 content being greater than P.sub.2 U-8.

Abstract: The flavor intensity of acetaldehyde and dimethyl sulfide is potentiated by combining the same with a small but effective amount of alginate.

Abstract: A cartridge for a bacteria screening device for detecting and recording the existence of bacteria and other microorganisms in a gaseous medium, such as a hospital operating room atmosphere, arranged to continuously or intermittently expose active culture media to a flow of the gaseous medium to impinge the bacteria and other microorganisms thereon and to thereafter incubate the exposed portions of the culture medium for detection and recording purposes. In the bacteria screening device, different active culture media, responsive to different bacteria, are on opposite surfaces of a strip mounted on supply and take up reels in an enclosed cartridge having apertures forming opposed limited exposure areas for the two sides of the strip. Interleaved with the strip carrying the culture media is a separating strip to prevent contact of exposed surfaces of culture media. The cartridge, designed to contain sufficient culture media for the monitored period of time, e.g.

Abstract: A stabilized proteinaceous particle containing either egg or cottage cheese is formed by combining therewith a binder and an amylaceous component. The resultant particle is incorporated in a moist food and is stable under retort canning conditions used to sterilize a moist food.

Abstract: In processes for measuring glycerides in a fluid, which processes require initial conversion thereof to glycerol, this conversion is achieved according to an improved and simplified saponifying reaction in which a reaction temperature between 35.degree. and 40.degree. C. is used.

Abstract: Forage crops such as perennial grasses, alfalfa, corn and sorghum in the wet or moist state are chopped into small pieces, a quantity of a composition consisting essentially of sodium diacetate and dehydrated whey is added, and the resultant mixture is placed in a storage container such as a silo and allowed to ferment to produce silage which is useful as an animal feed, especially for ruminant animals such as beef and dairy cattle.

Abstract: A swab is packaged in a tube having an open end and containing a culture-sustaining liquid at the bottom of a tube, and a plug including a one-way isolating valve located above the liquid and a barrier member forming an air-tight chamber between the plug and the barrier member. After removal of the swab from the tube and swabbing of a body canal or the like with the absorbent tip of the swab, the swab may be placed back in the tube with the absorbent tip adjacent the plug and within the substantially air-tight chamber. The plug may then be forced downwardly through the liquid by pressing on the end of the swab or another rigid member telescoped within the tube so as to force the liquid up through the valve into contact with the absorbent tip. A closure or cap which may be used to press on the end of the stick or the rigid member then forms a seal at the open end of the tube.

Abstract: The susceptibility of bacteria, particularly those derived from body fluids, to antimicrobial agents is determined in terms of an ATP index measured by culturing a bacterium in a growth medium, assaying the amount of ATP in a sample of the cultured bacterium by measuring the amount of luminescent light emitted when the bacterial ATP is reacted with a luciferase-luciferin mixture, subjecting the sample of the cultured bacterium to an antibiotic agent and assaying the amount of bacterial adenosine triphosphate after treatment with the antibiotic by measuring the luminescent light resulting from the reaction, whereby the ATP index is determined from the values obtained from the assay procedures.
