Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing compositions struggle with high whey protein concentrations due to gel formation and processing difficulties, leading to equipment fouling, and require solutions that allow higher concentrations while maintaining good processability and texture.
Innovation Solution
An aqueous composition comprising at least 8.0% whey protein and 2.0% Gum Arabic, with a pH of 5.0 to 9.0 and a weight ratio of Gum Arabic to whey protein between 0.25 and 1.00, which includes a heat-treatment process using Direct Steam Injection to prevent gel formation and maintain viscosity and texture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If whey protein concentration is increased to improve nutritional value, then protein content is improved, but gel formation occurs causing processing difficulties and equipment fouling
Solution Approach 1:
Gum Arabic acts as an intermediary substance that prevents direct gelation between whey protein molecules during heat treatment. The gum arabic forms a protective matrix around the whey protein, interfering with the gel network formation while allowing the high protein concentration to be maintained without processing issues
Solution Approach 2:
The invention changes the chemical composition parameters by introducing Gum Arabic at specific ratios (0.5-2.0% by weight) to modify the thermal behavior of whey protein. This parameter change prevents the phase transition that would otherwise lead to gelation, enabling high protein concentrations to be processed without fouling
2Quantity of substance
If whey protein concentration is increased to improve nutritional value, then protein content is improved, but equipment fouling increases
Solution Approach 1:
Gum Arabic serves as a protective intermediary that prevents whey protein from adhering to equipment surfaces during heat treatment. The gum arabic forms a non-sticking barrier layer that reduces fouling, allowing high protein concentrations to be processed through heating equipment without the harmful fouling effects
Solution Approach 2:
The invention converts the potential harm of high protein concentration (which would normally cause severe fouling) into a benefit by using Gum Arabic to control the thermal behavior. The gum arabic modifies the heat treatment process so that the high protein content can be effectively pasteurized without generating the harmful fouling that would otherwise occur
3Reliability
If heat treatment is applied to pasteurize high protein compositions, then microbial safety is improved, but gel formation occurs causing viscosity changes
Solution Approach 1:
Gum Arabic acts as a stabilizing intermediary during heat treatment that prevents the viscosity changes associated with gelation. While allowing the heat treatment to effectively pasteurize the product for microbial safety, the gum arabic maintains the compositional stability by preventing the protein network formation that would otherwise alter viscosity
Solution Approach 2:
The invention changes the thermal processing parameters by introducing Gum Arabic, which modifies the heat treatment behavior to achieve pasteurization without gelation. This parameter change allows the composition to withstand heat treatment for microbial safety while maintaining viscosity stability through the gum arabic's protective effect
