Disclosed is an NPN delivery system for a ruminant animal, the system comprising a complex of a zein-containing species or other proteinaceous species with a nitrogenous species. The NPN from the nitrogenous species is present in the complex in a form such that at least a portion of the NPN is not initially bioavailable to the rumen upon introduction of the system into the rumen of the ruminant animal. Preferably, the delivery system comprises a complex of urea with corn gluten. Also disclosed are methods for preparing an NPN delivery system for a ruminant animal.

Beer of low alcohol content is produced by preparing an all-malt brew using a high-temperature-tolerant cellulase. Mashing is conducted at a temperature of approximately 78.degree.-80.degree. C. After mashing, the wort is separated from the mash and fermented with yeast. After fermentation the all-malt beer is supplemented with a low dextrose equivalent (D.E.) starch hydrolyzate, filtered and treated with post-fermentive hopping and malt coloring, if desired. Finally, the drew is diluted with acidified deaerated water so as to contain not more than about 0.5% alcohol by volume.

Preparation of low alcohol beer

A process for the conversion of starch to syrups having a dextrose equivalent (D.E.) value of at least 90 and is achieved by treating liquid starch with glucoamylase for a period of not more than three hours.

Production of high D.E. syrups

Isoelectrically precipitated soy isolate is treated with a plant protease at a temperature of 70.degree. to 85.degree. C. to accomplish thinning or reduction of viscosity.

Modification of soy isolate

Starch liquefaction is accomplished using fungal amylase at a temperature of from about 75.degree. C. to 80.degree. C.

Liquefaction of starch

A malt source of enzymes is used to liquefy starch at high temperatures.

Starch liquefaction process

Torrefied, expanded barley for use as a partial replacement for malt in brewer's mashes is prepared by heating unmalted barley having a protein content of at least about 12% to a temperature sufficient to expand the barley to a degree that a given volume of barley before heating weights about 1.4 to about 1.75 times the weight of the same volume of barley after heating. Before heating, the unmalted barley preferably has a moisture content of about 12% to 20% by weight.

Torrefied barley for brewer's mashes

A non-distilled beer-type beverage is produced from a wort prepared from hydrolyzed starch that is fortified with a protein hydrolyzate, a source of ammonium ions and potassium phosphate.
