Embodiment 1

[0052] A vacuum reactor with a nominal capacity of 600 lbs equipped with a still pot was used. The tank was lined with glass and jacketed and was heated with steam and cooled with tap water. There is a mechanically driven paddle for stirring in the tank. Use an 8-inch diameter, 4.5-foot fractionation column packed with stainless steel Heliapack  , with 4-6 theoretical plates and adjustable reflux device during all equilibrium periods.

[0053] A 400-pound blend of distilled peppermint oil was used in the following procedure. The oil contained 1.3% water, 75 ppm dimethyl sulfide, and 6% menthofuran.

[0054] At time zero, the peppermint oil is loaded into a tank, which is 8mm absolute pressure, oil temperature 29°C, evaporation temperature 20°C, reflux 100%, and full steam and continuous heating. When liquid appeared in the reflux sight glass, turn on the collection at 100% and continue collecting the fraction until 40-60 lbs of low boiling point components were collected....

Embodiment 2

[0057] The same equipment as in Example 1 can be used in this example. In this example, both methyl sulfide and menthol furan were removed by distillation under reduced pressure. Charge 400 lbs of mixed distilled peppermint oil into a reactor pot. The peppermint oil contains about 1.7% water, 200 ppm dimethyl sulfide and 5% menthofuran.

[0058] At time zero, the peppermint oil is loaded into a tank with a pressure of 8 mm absolute, an oil temperature of 29° C., an evaporation temperature of 20° C., 100% reflux and continuous heating with complete steam. When liquid appeared in the reflux sight hole, turn on to collect at 100%, and collect the first 2% of about 6-8 lbs of distillate. This first distillate contains the vast majority of dimethyl sulfide and can be discarded. The oil temperature is about 70°C, the evaporation temperature is 20°C, and the vacuum is about 10mm. Continue the vacuum distillation process.

[0059] The temperature of the peppermint oil was gradual...

Abstract

The present invention provides a method for refining peppermint oil containing compositions. Additionally, the present invention provides a method for making chewing gum having a peppermint flavor. To this end, a method for refining a peppermint oil and menthofuran containing composition that includes sulfur compounds to remove at least a portion of the sulfur compounds and menthofuran is provided. The method comprises the step of subjecting the compososition to a distillation process that removes at least a portion of the sulfur compounds and menthofuran from the composition.

Description

Background of the invention [0001] The present invention relates to mint flavors in general, and more particularly to methods for refining mint flavors and their use in chewing gum. [0002] It is known in the chewing gum industry to add mint flavors to chewing gum. For example, it is known to add peppermint oil to chewing gum. In addition to adding the desired mouthfeel to the chewing gum, these mint flavors have a refreshing effect on the palate. [0003] However, gums with multiple mint flavors have a tendency to go sour later in chewing. This is partly due to the loss of most, if not all, of the sweetness effect, which makes most minty flavors noticeably sour. [0004] A method of reducing sourness is disclosed in US Patent No. 5,372,824 entitled "MINT FLAVORED CHEWINGGUM HAVING REDUCDED BITTERNESS AND METHODS FORMAKING SAME". In this patent, a method is provided for the preparation of chewing gum with a reduced sour mint flavor. In part, this patent discloses a chewi...
