摘要： The invention provides a method for reducing the protein content of tobacco material which includes either: (1) extracting the tobacco material with an anionic surfactant; (2) treating the tobacco material with a proteolytic enzyme followed by extraction with a surfactant; (3) applying a surfactant solution to the tobacco material, separating the solution from the tobacco material, removing the surfactant and polypeptides from the tobacco material, optionally with the use of an insoluble adsorbent, and combining the tobacco material with the remaining solution; or (4) first extracting the tobacco material with an aqueous solvent and then with a surfactant. The invention further provides a tobacco material of reduced protein content produced by extraction with an anionic surfactant.

摘要： This invention provides a method for reducing the protein content of tobacco material which includes extracting the tobacco material with a solution containing a surfactant. The tobacco material may be first extracted with an aqueous solvent to produce an aqueous extract before being treated with the solution containing a surfactant. This invention also provides a method for removing polypeptides from an aqueous extract of tobacco material which includes treating the extract with an insoluble adsorbent selected from the group comprising hydroxyapatite and a fuller's earth mineral such as bentonite. Treatment of the aqueous extract with bentonite will produce an extract having a reduced pigment and polypeptide content.
摘要翻译：本发明提供一种降低烟草材料的蛋白质含量的方法，其包括用含有表面活性剂的溶液萃取烟草材料。在用含有表面活性剂的溶液处理之前，可以首先用水性溶剂萃取烟草材料以产生水提取物。本发明还提供了一种从烟草材料的水提取物中除去多肽的方法，其包括用选自羟基磷灰石和富勒氏土矿物如膨润土的不溶性吸附剂处理提取物。用膨润土处理含水提取物将产生具有降低的颜料和多肽含量的提取物。
