Pre-cooked Pulse Flour as Sugar Replacement in Chocolate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Formulating sugar-reduced chocolate compositions that maintain texture and taste is challenging due to the negative impact of bulking agents on organoleptic and rheological properties, and the presence of anti-nutritional factors in pulse flours limits their utility in chocolate making.
Innovation Solution
Pre-cooked pulse flour, subjected to extrusion cooking and micronization, is used as a bulking agent to replace sugar and enhance protein content in chocolate compositions, reducing anti-nutritional factors and providing a unique flavor profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If sugar is replaced with bulking agents, then sugar content is reduced, but organoleptic and rheological properties deteriorate
Solution Approach 1:
The patent applies parameter changes by pre-cooking pulse flour at specific temperatures (90-120°C for 5-30 minutes) to modify its physical and chemical properties. This heat treatment reduces anti-nutritional factors while preserving bulking capabilities, allowing the flour to improve chocolate texture without the negative effects of conventional bulking agents.
Solution Approach 2:
The patent converts the harmful anti-nutritional factors in pulse flour (lectins, polyphenols, trypsin inhibitors, phytic acid) into beneficial components through pre-cooking. The heat treatment inactivates these anti-nutritional factors while maintaining the flour's bulking properties, transforming a potentially harmful ingredient into a beneficial sugar replacement.
2Quantity of substance
If pulse flour is used as bulking agent, then sugar content is reduced and protein content is enhanced, but anti-nutritional factors are introduced
Solution Approach 1:
The patent applies preliminary action by pre-cooking the pulse flour before incorporating it into chocolate. This preliminary heat treatment (90-120°C for 5-30 minutes) inactivates anti-nutritional factors such as lectins, polyphenols, trypsin inhibitors, and phytic acid, ensuring that the flour can be used safely as a sugar replacement without introducing harmful substances.
3Quantity of substance
If whole pulse flour is used, then bulking and protein enrichment are achieved, but particle size and texture are compromised
Solution Approach 1:
The patent applies segmentation by reducing the particle size of pulse flour through milling or extrusion processes. This breaks down the whole pulse flour into finer particles, improving its compatibility with chocolate ingredients and enhancing texture while maintaining the bulking and protein-enrichment benefits.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The use of pre-cooked pulse flour results in chocolate compositions with reduced sugar content, improved texture, and a pleasant taste, while minimizing the negative effects of anti-nutritional factors, making them suitable for various applications including vegan and protein-enriched options.
Implementation Method 1
the pulse flour has been subjected to extrusion cooking
Implementation Method 2
Pulse flour which has been pre-cooked can be used as an effective ingredient in chocolate making
Implementation Method 3
the pulse flour has been subjected to a particle size reduction technique, such as milling and/or micronization
Data Source
AI summary
The invention relates to the use of pulse flours as bulking agents in chocolate compositions. For example, a chocolate composition may include a pre-cooked pulse flour, a pulse flour that has been subjected to extrusion cooking, and/or a pulse flour that has been subjected to particle size reduction (e.g., milling and/or micronization).
