Claims28
A process of manufacturing a biodegradable playdough comprising at least 75 wt % of biodegradable components based on the total weight of the playdough, the process comprising:
- (a) particulating bread waste to an average particle size of at most 200 μm, thereby obtaining particulated bread waste;
- (b) mixing the particulated bread waste with at least one rheology modifier, at least one retrogradation prevention agent and water to obtain a mixture, wherein said mixture comprises at least 30 wt % bread waste and maintaining the mixture at a temperature of at least about 40° C. for a predefined period of time;
- and
- (c) cooling the mixture to a room temperature to obtain said biodegradable playdough.
A biodegradable playdough composition, comprising:
- i) at least about 30 wt % bread waste wherein the bread waste is in particulate form, having an average particle size of no more than about 200 μm,
- ii) at most about 50 wt % water, and
- iii) a combination of functional additive comprising at least one rheology modifier and at least one retrogradation preventing agent, the biodegradable playdough composition comprising at least about 75 wt % of biodegradable components based on the total weight of the composition, the biodegradable playdough composition having a complex viscosity of between about 1×104 and about 1×106 Pa·s (as measured by parallel plates rheometer, at 25° C., at 0.1 Hz).
A kit comprising one or more portioned quantities of a playdough composition and at least one organoleptic additive, the playdough composition comprising:
- i) at least about 30 wt % bread waste wherein the bread waste is in particulate form, having an average particle size of no more than about 200 μm,
- ii) at most about 50 wt % water, and
- iii) a combination of functional additive comprising at least one rheology modifier and at least one retrogradation preventing agent, the biodegradable playdough composition comprising at least about 75 wt % of biodegradable components based on the total weight of the composition, the biodegradable playdough composition having a complex viscosity of between about 1×104 and about 1×106 Pa·s (as measured by parallel plates rheometer, at 25° C., at 0.1 Hz).
