  Disclosed is a photo- and/or thermo-curable copolymer having polymerizable unsaturated groups in side chains, which is obtainable by reacting a copolymer (P) with an epoxy-containing polymerizable unsaturated compound (C), the copolymer (P) containing monomer units derived from a carboxyl-containing polymerizable unsaturated compound (A) and monomer units derived from at least one epoxy-containing polymerizable unsaturated compound (B) represented by following Formula (1) or (2), in which the epoxy group of the epoxy-containing polymerizable unsaturated compound (C) has been added to part of the carboxyl groups of the copolymer (P). In the formulae, Ras each represent hydrogen or hydroxyl-substituted or -unsubstituted alkyl having 1 to 4 carbon atoms; and Rbs each represent single bond or alkylene having 1 to 18 carbon atoms which may contain heteroatom(s). The curable copolymer is highly stably synthesized and stored, has satisfactory curing properties, and permits both epoxy crosslinking and radical crosslinking.

  Disclosed is a process for the co-manufacture of ingredients having food and beverage applications, using potatoes as starting material. The process comprises six steps. The first step is a cutting and dipping of washed raw potatoes in an anti-oxidant solution. The second step is an extraction of undiluted juice free of starch and fibers from a purée made from the anti-oxidant-dipped raw potatoes. The third step is a concentration and enzymatic treatment of the juice. The fourth step is a heating of the juice to specific temperatures to cause precipitation of proteins and separation of precipitated protein therefrom. The fifth step is a thermal browning of the clear juice. The sixth step is an adjustment of the final pH of the juices of the fourth and fifth steps and a blending of these juices in ratios appropriate for intended use. These six steps yield products which may be used as the main flavor principle in malt-free beer, as a coffee substitute and as a flavor enhancer in savory mixes. They also yield dietary fibers, a concentrated edible protein and non-gelatinized granular starch, thereby increasing revenues derived from potato processing while minimizing liquid waste stream.

  本发明公开了一种以马铃薯为起始原料，共同制造具有食品和饮料用途的配料的工艺。该工艺包括六个步骤。第一步是将洗净的生马铃薯切碎并浸泡在抗氧化剂溶液中。第二步是从浸过抗氧化剂的生马铃薯泥中提取不含淀粉和纤维的未稀释果汁。第三步是对果汁进行浓缩和酶处理。第四步是将果汁加热到特定温度，使蛋白质沉淀并从中分离出沉淀的蛋白质。第五步是对透明果汁进行热褐变处理。第六步是调整第四步和第五步果汁的最终 pH 值，并将这些果汁按预定用途的适当比例混合。这六个步骤产生的产品可用作无麦芽啤酒的主要风味原料、咖啡替代品和咸味混合食品的增味剂。它们还能产生膳食纤维、浓缩食用蛋白质和非胶化颗粒淀粉，从而增加马铃薯加工的收入，同时最大限度地减少液体废物流。
