Baked Goods with High Slowly Digestible Starch
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing baked goods with high levels of slowly digestible starch (SDS) face challenges in achieving a cohesive, non-crumbly texture while maintaining high SDS content, as high moisture and baking temperatures often lead to gelatinization and reduced SDS levels.
Innovation Solution
A method involving the use of a starch component with at least 20% gelatinization, including partially hydrolyzed maize starch and sago starch, and controlling starch properties such as amylose ratio and hydrodynamic radius, to produce baked goods with a high SDS content and low crumbliness, achieved through specific baking and processing conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If high moisture and baking temperatures are used to achieve soft texture, then texture quality is improved, but slowly digestible starch content decreases due to gelatinization
Solution Approach 1:
The patent changes the parameters of starch by using partially hydrolyzed maize starch with controlled degrees of hydrolysis (10-30 DE) and specific gelatinization temperatures. This allows the starch to maintain SDS content while achieving desired texture through controlled gelatinization at specific temperature ranges
Solution Approach 2:
The patent uses composite starch systems combining partially hydrolyzed maize starch with other starches (wheat starch, sago starch, tapioca starch) to create a blended starch system that maintains both soft texture and high SDS content, leveraging the complementary properties of different starch sources
2Reliability
If high levels of slowly digestible starch are achieved, then health benefits and sustained energy release are improved, but product structure becomes crumbly and cohesive
Solution Approach 1:
The patent modifies starch parameters through controlled partial hydrolysis to create starch with enhanced water binding capacity and specific gelatinization properties, allowing high SDS content (≥14g/100g) to be achieved while maintaining structural integrity through optimized molecular weight distribution
Solution Approach 2:
The patent uses hydrocolloids (xanthan gum, guar gum, carrageenan, pectin) as intermediary substances that interact with the starch matrix to provide structural support and reduce crumbliness, allowing high SDS content to be maintained without compromising product coherence
3Shape
If gelatinization is increased to improve texture, then texture quality is improved, but slowly digestible starch content decreases
Solution Approach 1:
The patent uses starch with controlled gelatinization temperature ranges (60-80°C for partially hydrolyzed maize starch) to achieve optimal texture while preserving SDS. The hydrolyzed starch gelatinizes at lower temperatures than native starch, allowing texture improvement without complete gelatinization that would eliminate SDS
Solution Approach 2:
The patent performs preliminary partial hydrolysis of starch before baking to create starch with modified gelatinization properties. This pre-treatment ensures that during baking, the starch gelatinizes at controlled rates, maintaining both texture quality and SDS content by preventing excessive gelatinization
