Problems solved by technology

The problem associated with this is that a rather high percentage of the enzyme used is lost during chewing as it migrates into the saliva and further into the stomach of the consumer

Embodiment 1

[0281] Preparation of polyester elastomers by step-growth polymerization

[0282] Elastomer samples were produced using a 500 mL resin kettle equipped with an overhead stirrer, nitrogen inlet, thermometer, and distillation head for methanol removal. Charge 83.50 g (0.43 moles) of dimethyl terephthalate, 99.29 g (0.57 moles) of dimethyl adipate, 106.60 g (1.005 moles) of bis(ethylene glycol) and 0.6 g of calcium acetate monohydrate in the cauldron. The mixture was heated slowly under nitrogen with stirring until all components were molten (120-140°C). Heating and stirring were continued to continuously distill methanol. The temperature was slowly raised to 150-200°C until methanol evolution ceased. Turn off the heat and allow the contents to cool to about 100°C. The reactor lid was removed and the molten polymer was carefully poured into a receiving vessel.

[0283] The product was characterized by Mn = 40,000 g / mol, Mw = 190,000 g / mol, Tg = -30°C.

Embodiment 2

[0285] Preparation of polyester resins by ring-opening polymerization

[0286] Resin samples were produced using a jacketed 10 L cylindrical glass test reactor equipped with a glass stirring shaft and Teflon stirring blades and bottom outlet. Heating of the reactor contents was achieved by circulation of silicone oil through the external jacket thermostated at 130°C. ε-caprolactone (358.87g, 3.145mol) and 1,2-propanediol (79.87g, 1.050mol) with stannous octoate (1.79g, 4.42×10 -3 mol) were charged into the reactor together and reacted at 130° C. for about 30 minutes. Molten D,L-lactide (4.877 kg, 33.84 mol) was then added and the reaction continued for about 2 hours. After the reaction was complete, the bottom outlet was opened to allow the molten polymer to discharge into a Teflon-lined paint tank.

[0287] The product is characterized as M n = 6,000 g / mol, Mw = 7,000 g / mol, Tg = 25-30°C.

Embodiment 3

[0289] Preparation of polyester resins by ring-opening polymerization

[0290] Resin samples were prepared by polymerization similar to Example 2 at a molar ratio of 50% D,L-lactide to 50% glycolide.

[0291] The product is characterized as M n = 6,000 g / mol, Mw = 7,000 g / mol, Tg = 36°C.

Abstract

A chewing gum comprising at least one biodegradable polymer, sweetener in an amount from about 0.5% to about 95% of said chewing gum, one or more flavoring agents, filler in an amount from about 0 to 50% by weight of said chewing gum, further chewing gum ingredients and at least one enzyme, wherein said at least one enzyme is comprised in a hydrophobic enzyme formulation. According to the invention, it has been established that an enzymatically activated degradation may by obtained when applying a hydrophobic enzyme formulation even though the hydrophobic enzyme formulation, e.g. when applying a dispersion of substantially hydrophilic enzymes in a hydrophobic medium such as oil, might be suspected to have a negative influence on the functionality of the enzymes at the active sites of the applied enzyme.

Description

technical field [0001] The present invention relates to a chewing gum according to claim 1 . Background technique [0002] It is generally recognized that chewing gum discarded in indoor or outdoor environments can cause considerable nuisance and inconvenience as it sticks strongly to surfaces such as streets and sidewalks and to the people present or moving in the environment shoes and clothes. What substantially causes such trouble and inconvenience is that existing chewing gum products are based on the use of elastomeric and resinous polymers of natural or synthetic origin which are substantially non-degradable in the environment. [0003] As a result, municipalities and others responsible for cleaning indoor and outdoor environments must expend considerable effort to remove discarded chewing gum, but these efforts are not only costly, but also ineffective. [0004] Attempts have been made to reduce the nuisance associated with the widespread use of chewing gum, for exa...
