Abstract A method of providing a low carcinogen content smoke aerosol for use in the smoking of food products. The removal of carcinogens from natural hardwood smoke is effected by cycloning conventionally generated smoke to remove a substantial portion of the particulate phase thereof and/or by regenerating a condensed natural hardwood smoke in the presence of heat. Products may be smoked in the conventional manner or by application of a condensed liquid smoke to a product by dipping, spraying or mixing the condensed liquid smoke into the product as an ingredient thereof. The process also provides the advantages of increasing the cleanliness of a smoke generating operation, reducing the fire hazard thereof and providing a smoking process that can be closely controlled thereby enhancing reproducibility.
The method of claim wherein step (b) is accomplished by feeding the smoke from step (a) through a cyclone of a sufficiently small size to separate out colloidal size particles at a temperature in the range of about 180*- 300* F.
Claim 2
Independent Claim
60 words
A method of making a reduced carcinogen content smoke aerosol for use in the smoking of foods comprising the step of vaporizing a liquid smoke composition at an elevated temperature in the range of about 220* to 850* F. to generate a smoke aerosol having a carcinogen content reduced from that of the liquid smoke composition prior to its vaporization.
Claim 3
Dependent Claim
34 words
A method of preparing a reduced carcinogen content smoked foodstuff utilizing the method of claim 3 to generate a smoke aerosol, and thereafter subjecting a foodstuff to the smoke aerosol to smoke the same.
Claim 4
Independent Claim
76 words
A method of making a reduced carcinogen content smoked foodstuff comprising the steps of: a. subjecting a desired wood to heat to generate smoke; b. passing the smoke through a cyclone of sufficiently small size at a temperature in the range of about 180*- 300* F. to remove a substantial portion of the particulate phase of the smoke containing the majority of the carcinogens found therein; and c. thereafter subjecting a foodstuff to the remaining smoke.
Claim 5
Dependent Claim
50 words
The method of claim 5 wherein the step of subjecting a foodstuff to the smoke is preceded by the steps of condensing the reduced carcinogen content smoke to a liquid, and dispersing the liquid smoke; and the foodstuff is subjected to the smoke by contact with the dispersed liquid smoke.
