Solution Overview
Problem
There is a need for high protein bakery products that are convenient, low in sugar and wheat flour, and suitable for microwave cooking, with improved texture and flavor, while minimizing cost and acrylamide formation.
Innovation Solution
A method of forming a high protein bakery product using a particulate mixture comprising flaxseed, chia seed, soluble fibre, gluten, pulse protein, whey protein, and egg, with minimal sugar and wheat flour, mixed with a liquid carrier and cooked in a microwave oven, which results in a product with high protein and fibre content and reduced acrylamide levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional bakery techniques are used to prepare high protein bakery products, then the products can achieve acceptable texture and flavour, but the preparation time is excessively long (30 minutes to 2 hours) and cannot be classified as convenience food
Solution Approach 1:
The patent applies preliminary action by pre-formulating a complete particulate mixture containing all necessary ingredients (proteins, fibres, leavening agents, flavorings) in precise proportions. This pre-prepared mix eliminates the need for consumers to perform traditional mixing, kneading, and proofing steps, reducing preparation time from 30 minutes to 2 hours down to just minutes while maintaining product quality
Solution Approach 2:
The patent changes the physical and chemical parameters of the dough formulation by using a optimized particulate mixture with specific protein sources (whey protein, soy protein, pea protein), fibres, and leavening agents that enable rapid cooking. The mixture is designed to achieve proper rise and texture in microwave ovens within 1-3 minutes, fundamentally changing the time-temperature parameters from traditional baking
2Quantity of substance
If high protein content is achieved in bakery products, then nutritional value is improved, but the products become difficult to manufacture with acceptable texture and flavour
Solution Approach 1:
The patent uses composite materials by combining multiple protein sources (whey protein, soy protein, pea protein) and fibre types in a particulate mixture. This composite approach allows achieving high protein content (30-50% of total weight) while maintaining acceptable texture and flavour, as each component contributes different functional properties that complement each other
Solution Approach 2:
The patent applies local quality by distributing different ingredients throughout the particulate mixture in specific zones or proportions. The mixture contains proteins, fibres, leavening agents, and flavorings in precise local concentrations that ensure uniform distribution during rapid microwave cooking, achieving consistent texture and flavour throughout the final product
3Duration of action of stationary object
If pre-made high protein bakery products are manufactured with extended shelf-life, then storage stability is improved, but the products require restricted moisture levels which limits textural quality
Solution Approach 1:
The patent applies preliminary action by providing a dry particulate mixture that is stable during storage, then adding liquid carrier material immediately before cooking. This approach allows the mix to be stored dry for extended periods while maintaining stability, and only introduces moisture at the point of use, enabling both long shelf-life and high moisture content in the final cooked product for superior texture
Solution Approach 2:
The patent segments the product into two phases: a dry stable particulate mixture for storage and a liquid carrier material added before cooking. This segmentation allows the dry mix to maintain stability during extended storage, while the liquid component is introduced only when needed, enabling the final product to achieve high moisture content (above 40%) for improved texture without compromising storage stability
4Ease of manufacture
If traditional baking methods are used to achieve browning and surface development, then flavour and appearance are improved, but acrylamide formation increases creating health concerns
Solution Approach 1:
The patent replaces the traditional thermal baking mechanism with microwave heating. Microwave radiation directly heats the water molecules in the dough, causing rapid internal heating and steam generation that produces rise and cooking without significant surface browning. This substitution eliminates the Maillard reaction conditions that generate acrylamide, while still achieving acceptable flavour and appearance through the particulate mixture formulation
Solution Approach 2:
The patent changes the heating parameters from conventional oven temperatures (180-200°C) to microwave heating at lower temperatures. The microwave process cooks the product rapidly in 1-3 minutes at temperatures below 100°C, preventing the thermal conditions necessary for acrylamide formation while still achieving proper cooking through internal steam generation and protein coagulation
