Native Whole Starch Fat Replacer With Controlled Retrogradation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing starch-based fat replacers, both native and modified, fail to adequately mimic the organoleptic properties of animal fats, are insoluble in cold water, and suffer from retrogradation issues that affect food product quality, shelf-life, and consumer acceptance, while modified starches are not preferred by consumers seeking natural ingredients.
Innovation Solution
A native-whole-starch-based fat replacer is developed using a colloidal-emulsion of native whole starch, plant-based fat, and water, with minimal processing, to achieve fat-like forming, solidifying, and low heat melting properties through a controlled retrogradation process, without gelling or thickening agents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If native starches are used as fat replacers, then the product is naturally occurring and minimally processed, but the starch remains insoluble in cold water and swells at different temperatures causing consistency issues
Solution Approach 1:
The patent applies parameter changes by controlling the retrogradation process through specific temperature and time parameters. The starch is cooked at elevated temperatures then cooled to controlled temperatures (refrigeration or freezing) for specific durations to achieve desired retrogradation levels, transforming the starch properties from inconsistent to stable and predictable
Solution Approach 2:
The patent applies preliminary action by pre-cooking the native starch before the retrogradation process. This preliminary cooking step gelatinizes the starch, making it more uniform and preparing it for controlled retrogradation, which subsequently improves consistency and reduces swelling variability
2Reliability
If native starch undergoes retrogradation to improve functional properties, then quality and shelf-life are enhanced, but staling of food products occurs causing reduced consumer acceptance
Solution Approach 1:
The patent applies partial action by controlling the retrogradation process to achieve only the desired level of firmness and texture improvement without allowing excessive retrogradation that would cause staling. The starch is retrograded under controlled conditions and then combined with other ingredients that mask or prevent further retrogradation-related staling
Solution Approach 2:
The patent converts the harmful effect of retrogradation (staling) into a beneficial effect by controlling the process to achieve desirable firmness and texture in the fat replacer itself. The retrograded starch provides structural integrity to the fat replacer while the timing and conditions are managed to prevent staling in the final food product
3Adaptability or versatility
If modified starches are used to improve functional properties, then the starch can be tailored for specific applications, but the product contains additives that conscientious consumers avoid
Solution Approach 1:
The patent applies the extraction principle by removing the need for chemical modifiers and additives entirely. Instead of using modified starches with added chemicals, the patent extracts and utilizes only the native starch component, relying on controlled physical processing (cooking and retrogradation) to achieve the desired functional properties without any additives
Solution Approach 2:
The patent achieves adaptability and versatility through parameter changes in the processing conditions rather than chemical modification. By varying temperature, time, and moisture content during cooking and retrogradation, the native starch can be tailored for different applications while remaining free of additives
