Modified Wheat Protein Isolate Binder for Low-Carb Food Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current food binders used in food systems, such as those found in bars and snacks, often increase sweetness and are carbohydrate-based, with limited options available that do not elevate sweetness levels and are not suitable for low-carbohydrate diets.
Innovation Solution
A protein-based binder system utilizing a modified wheat protein isolate, which is treated with an acid and a reducing agent to reduce viscoelastic properties, combined with humectants and sweeteners, to create a binder that effectively binds food particulates and powders without increasing sweetness and can be used in low-carbohydrate formulations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If carbohydrate-based binders are used to bind food particulates, then effective binding properties are achieved, but sweetness increases and carbohydrate content rises
Solution Approach 1:
The patent changes the chemical composition parameters of the binder from carbohydrate-based to protein-based (wheat protein isolate), fundamentally altering the substance type to eliminate the contradiction between binding effectiveness and carbohydrate content. The protein isolate is treated with acid and reducing agents to optimize its binding properties while maintaining low carbohydrate content.
Solution Approach 2:
The patent creates a protein-based binder that copies the functional properties of traditional carbohydrate-based binders (adhesion, cohesion, binding) while using a different chemical substrate (protein instead of carbohydrates), thereby achieving similar binding effectiveness without the unwanted sweetness and high carbohydrate content.
2Reliability
If wheat protein isolate is treated with acid and reducing agents to reduce viscoelastic properties, then binding effectiveness improves, but processing complexity increases
Solution Approach 1:
The wheat protein isolate is pre-treated with acid and reducing agents before use as a binder, modifying its viscoelastic properties in advance to enhance binding effectiveness. This preliminary treatment ensures the protein isolate has optimal binding characteristics when applied to food particulates, while the treatment process itself is a standard food processing operation.
