Abstract
A chewing gum base comprises rubber derived from Russian Dandelion (TKS). Methods of extracting and purifying the rubber are provided. Gum base compositions and methods of compensating for variable ratios of elastomer:resin in the rubber are disclosed.
Claims17
A chewing gum base comprising
- 1 to 30 wt. % TKS rubber,
- an additional a resin that is present in an amount of up to about 40% by weight, the resin comprising terpene resin;
- 0 to 20 wt. % synthetic elastomer,
- 0 to 20 wt. % natural elastomer other than TKS rubber,
- about 0 to about 35 wt. % filler,
- about 0 to about 35 wt. % softener,
- 0 to 5 wt. % emulsifier, and
- 0 to 40 wt. % hydrophilic modifier;
- wherein the TKS rubber comprises 70-95% polyisoprene elastomer and a balance of resin, and
- wherein the ratio of the polyisoprene elastomer to total resin in the composition gum base is from 1:1 to 1:5.
7 more elements
A method of producing compositionally consistent chewing gum bases comprising the steps of
- a. creating a master formula for a gum base having a desired texture and containing at least TKS rubber and a terpene resin using a first TKS rubber batch having a known ratio of polyisoprene elastomer:resin;
- b. analyzing a second batch of TKS Rubber to determine its polyisoprene elastomer:resin ratio;
- c. adjusting the levels of TKS rubber and terpene resin in the master formula to compensate for the difference in polyisoprene elastomer:resin ratios of the second batch of TKS rubber compared to the first batch of TKS rubber such that the final polyisoprene elastomer level and resin level in the gum base match those of the master formula;
- and
- d. preparing at least one batch of gum base using the adjusted formula.
2 more elements
A method of producing compositionally consistent chewing gum bases comprising the steps of
- a. selecting a standardized ratio of polyisoprene elastomer:resin falling within the natural range of about 70 to 95% polyisoprene elastomer and a balance of resin;
- b. blending two or more batches of TKS rubber having known ratios of polyisoprene elastomer:resin to create a first standardized batch of TKS rubber having the selected standardized ratio of polyisoprene elastomer:resin;
- c. formulating at least one gum base using the first standardized batch of TKS rubber;
- d. preparing at least a second standardized batch of TKS rubber having the same polyisoprene elastomer:resin ratio as the first standardized batch of TKS rubber;
- and
- e. preparing at least one batch of the at least one formulated gum base using the at least second standardized batch of TKS rubber.
3 more elements
