Abstract: A method of making a fully hop flavored beverage employs a hop flavoring agent comprising an extract of hop solids, the hop solids being the residue of a first extraction of hops to remove the alpha acids. Preferably, liquid carbon dioxide is used for the first extraction of the hops and a polar solvent, such as ethanol or water, is used to extract the hop solids. Beverages made by the method and novel compositions for use in the method are also disclosed.

Abstract: A sugar syrup is prepared by saccharifying a liquefied starch hydrolyzate at a pH of about 4 to about 5.5 and a temperature above 55.degree. C. with a heat stable, aciduric, pullulanase obtained from rice and an .alpha.-1,4 carbohydrase. The pullulanase employed is substantially free of maltase and transglucosidase activity. In one embodiment, a dextrose syrup is prepared by saccharifying a thinned starch hydrolyzate with glucoamylase and the rice pullulanase. Maltose syrup is prepared using the rice pullulanase and a maltogenic enzyme.

Abstract: Low calorie beer is prepared by introducing into the brewing process a debranching enzyme (pullulanase) obtained from rice, a traditional brewing material. The debranching enzyme reduces the real extract of the beer by cleaving alpha 1,6 linkages of unfermentable limit dextrins to form alpha 1,4 dextrins which can be converted by alpha 1,4 carbohydrases to sugars that can be fermented by brewer's yeast. The enzyme may be introduced into the brewing process by adding rice or the enzyme extracted from rice to the mash or to the wort before or during fermentation. The debranching enzyme may be obtained from polished dry milled rice by extraction with an aqueous buffer solution. When malted rice is used as the enzyme source a particularly useful mixture of the debranching enzyme and alpha 1,4 carbohydrases is obtained.

Abstract: A debranching enzyme (pullulanese) useful in the preparation of a low calorie beer may be obtained from rice by extraction of the rice with an aqueous buffer system having a pH of about 6. A preferred buffer system is 0.1 M potassium phosphate-0.2 M-sodium chloride. Extraction is preferably carried out at a temperature of about 50.degree. C. for about 3 hours. When malted rice is used as the enzyme source a particularly useful mixture of the debranching enzyme and alpha 1,4 carbohydrases is obtained.

Abstract: A product for human consumption containing protein and having a high dietary fiber content and a low phytic acid content is produced by drying brewer's spent grain, milling the dried brewer's spent grain to obtain a ground product having particle sizes ranging from about 600 microns down to about 50 microns and isolating the ground particles having a particle size of at least about 120 microns which constitute the product and contain about 18% to 22% protein and about 65% to 75% dietary fiber.
