    • Process for cross-linking proteins involves contacting the proteins with at least one ketose containing specific carbon atoms (0.5 to 20, preferably 1 - 10, especially 1 - 5 wt.%); maintaining the contact between the proteins and the ketose for a period of time greater than a few minutes (preferably 10 - 60 minutes, especially 30 minutes), at 20 - 105 (preferably 35 - 105)[deg]C; and recovering the cross-linked proteins thus obtained. Process for cross-linking proteins involves contacting the proteins with at least one 3-5C ketose (0.5 to 20, preferably 1 - 10, especially 1 - 5 wt.%); maintaining the contact between the proteins and the ketose for a period of time greater than a few minutes (preferably 10 - 60 minutes, especially 30 minutes), at 20 - 105 (preferably 35 - 105)[deg]C; and recovering the cross-linked proteins thus obtained. The protein is selected from group comprising proteins from animal tissues, from milk or from blood (such as casein, gelatin or collagen); proteins from cereals (such as maize, wheat or rice proteins); proteins from high-protein plants (such as pea, alfalfa, lupin, barley, millet or sorghum proteins); proteins from oleaginous plants (such as soybean proteins e.g. soybean cakes, rapeseed or flax proteins, rapeseed cakes, sunflower, groundnut or cotton proteins); and proteins from tubers (such as potato or manioc). Independent claims are included for the following: (1) preparation of animal feed (e.g. feed for ruminants or for pets, or feed used in aquaculture) involving replacement of either proteins treated with mineral tannins (preferably proteins tanned with zinc salts), or proteins treated with aldehyde tannins (preferably proteins tanned with formaldehyde, with glyoxal or with glutaraldehyde, especially proteins tanned with formol) with the cross-linked proteins; (2) preparation of film-forming compositions for coverings, coatings or adhesives involving replacement of proteins tanned with either synthetic tannins (preferably proteins tanned with epichlorohydrin resins, polyamide-amine-epichlorohydrin resins, polyethyleneimine resins or isocyanate resins), or with aldehyde tannins (preferably proteins tanned with formaldehyde, with glyoxal or with glutaraldehyde, especially proteins tanned with formoare) with the cross-linked proteins; and (3) preparation of biodegradable or renewable protein materials (e.g. plastic films, leathers, textile fibers, gelatin capsules, capsules, or protein feed compositions) involving replacement of either proteins tanned with mineral tannins (preferably proteins tanned with chrome), or proteins tanned with aldehyde tannins (preferably proteins tanned with formaldehyde, with glyoxal or with glutaraldehyde, especially proteins tanned with formol) with the cross-linked proteins.
    • 交联蛋白质的方法包括使蛋白质与至少一种含有特定碳原子的酮糖(0.5至20,优选1-10,特别是1-5重量%)接触; 在20-105(优选35-105℃)下保持蛋白质和酮糖之间的接触时间大于几分钟(优选10-60分钟,特别是30分钟); 并回收由此获得的交联蛋白质。 交联蛋白质的方法包括使蛋白质与至少一种3-5C酮糖(0.5至20,优选1-10,特别是1-5重量%)接触; 在20-105(优选35-105℃)下保持蛋白质和酮糖之间的接触时间大于几分钟(优选10-60分钟,特别是30分钟); 并回收由此获得的交联蛋白质。 蛋白质选自包含来自动物组织的蛋白质,来自牛奶或血液的蛋白质(例如酪蛋白,明胶或胶原蛋白); 来自谷物(如玉米,小麦或水稻蛋白)的蛋白质; 来自高蛋白植物(如豌豆,苜蓿,羽扇豆,大麦,小米或高粱蛋白质)的蛋白质; 来自含油植物的蛋白质(例如大豆蛋白质,例如大豆蛋糕,油菜籽或亚麻蛋白质,油菜籽蛋糕,向日葵,花生或棉花蛋白质); 和块茎(如马铃薯或manioc)的蛋白质。 独立权利要求包括以下内容:(1)制备动物饲料(例如反刍动物或宠物的饲料,或用于水产养殖的饲料),包括用矿物质单宁(优选用锌盐鞣制的蛋白质)或蛋白质 用交联蛋白质用醛单宁(优选用甲醛鞣制的蛋白质,用乙二醛或与戊二醛,特别是用甲醛鞣制的蛋白质)进行处理; (2)制备用于覆盖物,涂料或粘合剂的成膜组合物,其包括用合成单宁(优选用表氯醇树脂鞣制的蛋白质,聚酰胺 - 胺 - 表氯醇树脂,聚乙烯亚胺树脂或异氰酸酯树脂)鞣制的蛋白质或用醛单宁 (优选用甲醛鞣制的蛋白质,具有乙二醛或与戊二醛,特别是通过形式鞣制的蛋白质)与交联蛋白质; 和(3)制备可替代的可生物降解或可再生的蛋白质材料(例如塑料薄膜,皮革,纺织纤维,明胶胶囊,胶囊或蛋白质进料组合物),包括用矿物质单宁(优选用铬鞣制的蛋白质)或蛋白质 用交联蛋白质与鞣酸单宁(优选用甲醛鞣制的蛋白质,用乙二醛或与戊二醛,特别是用甲醛鞣制的蛋白质)进行鞣制。
