Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current cellulose composites fail to effectively suppress precipitation and aggregation of water-insoluble components in beverages, particularly at high temperatures, leading to unsatisfactory suspension stability and texture issues in beverages containing cocoa, peanuts, and flour.
Innovation Solution
A cellulose composite comprising microcrystalline cellulose and water-soluble carboxymethyl cellulose with specific properties, including a tan δ of 0.60 or lower and a storage modulus of 2 Pa or higher, is developed to enhance suspension stability by forming a network structure that prevents separation and aggregation even at elevated temperatures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cellulose composites are used to stabilize suspensions in beverages, then some suspension stabilization is achieved, but precipitation and aggregation occur at high temperatures leading to inadequate stability
Solution Approach 1:
The invention uses a composite material consisting of microcrystalline cellulose (MCC) and carboxymethyl cellulose (CMC) with specific degree of substitution ranges (0.7-1.3). This composite structure combines the suspension stabilization capability of MCC with the temperature resistance and solubility enhancement provided by CMC, creating a material that maintains stability at high temperatures where conventional single-component cellulose composites fail.
Solution Approach 2:
The invention specifies precise parameter ranges for the cellulose composite: degree of substitution of CMC (0.7-1.3), viscosity (50-500 cps), and particle size distribution. By controlling these parameters within specific ranges, the composite achieves optimal balance between suspension stabilization and high-temperature resistance, preventing the precipitation and aggregation that occur with conventional composites at elevated temperatures.
2Reliability
If cellulose composite is added to stabilize water-insoluble microparticles, then suspension stabilization is improved, but texture issues and heaviness occur in the beverage
Solution Approach 1:
The invention optimizes the viscosity parameter of the cellulose composite to a specific range (50-500 cps) and controls the degree of substitution (0.7-1.3). These parameter adjustments ensure that the composite provides adequate suspension stabilization while maintaining appropriate fluidity and light texture in the beverage, avoiding the heaviness and soggy texture associated with higher viscosity composites.
3Reliability
If higher amounts of cellulose composite are added to enhance suspension stability, then precipitation suppression improves, but viscosity increases and beverage fluidity decreases
Solution Approach 1:
The composite of MCC and CMC with degree of substitution 0.7-1.3 provides enhanced precipitation suppression efficiency per unit mass compared to conventional composites. This allows the use of lower overall amounts of cellulose composite in the beverage formulation, thereby achieving adequate precipitation suppression without excessive viscosity increase and maintaining good fluidity.
