Abstract

1,000,057. Tobacco substitutes. P. C. R. TORIGIAN. Sept. 26, 1963, No. 37944/63. Heading A2C. A method of treating cured leaves of leafy vegetables and plants other than tobacco (e.g. lettuce, corn, potato, peanut or spinach) to produce a non-toxic product resembling and usable like tobacco and having combustion products of reduced tar and resin content, comprises promoting the natural enzymatic reactions in the leaves under controlled temperature, pH and humidity conditions to develop a pleasing flavour, destroying the enzymes and then subjecting the leaves to further enzymatic hydrolysis by adding them to an enzymebearing solution of a proteolytic enzyme and continuing the enzymatic hydrolysis until the leaves acquire the appearance of smoking tobacco. The enzyme-bearing solution is maintained at pH value of 4-5 and at a temperature of 25‹ to 45‹C. for a period not exceeding about 12 hours. Prior to treatment with the enzyme-bearing solution, the leaves are treated in an enclosure at a temperature of 25‹ to 40‹C. in an atmosphere having a relative humidity of 60-90%, the atmosphere being replaced not more than every 20 minutes until the leaves acquire the physical characteristics of cured tobacco leaves. The relative humidity is then preferably lowered to below 60% while the temperature is raised to 90‹-120‹C., the sulphur dioxide having been removed from the atmosphere. After treatment with the enzyme-bearing solution the leaves are washed and dried to a moisture content of 10-15%. The enzymebearing solution preferably contains the enzyme, which may be papain, in the amount of 1% based on the weight of the leaves. Either sulphur dioxide or ammonia may be used to control the pH value during and enzymatic hydrolysis. The enzymatically hydrolysed leaves may be subjected to a second enzymatic hydrolysis with an amylolytic enzyme or lipolytic enzyme. Two quantitative examples are given.
