Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gluten-free bakery and patisserie products lack the organoleptic and rheological properties of their gluten-containing counterparts, failing to meet consumer requirements for taste, texture, and satisfaction.
Innovation Solution
A method involving the mixing of gluten-free flours, starches, fibers, and enzymes, followed by ultra-fine wet grinding and aeration to create a colloidal dough, which is then extruded, cut, and cooked in a microwave oven, with optional final baking in a convection oven, to achieve the desired properties without using gluten substitutes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional baking methods are used for gluten-free products, then the production process is simpler, but the organoleptic and rheological properties are insufficient
Solution Approach 1:
The patent transforms the dough into a colloidal state by controlling particle size (10-100 nanometers) and water content (60-110% of solid mixture weight), then uses microwave radiation (2.45-9.15 GHz) at specific temperatures (80-95°C) to achieve proper cooking and texture without conventional baking methods
Solution Approach 2:
The patent replaces conventional thermal baking with microwave radiation heating, using electromagnetic energy (2.45-9.15 GHz frequency range) to cook and dry the colloidal dough pieces, achieving the desired organoleptic properties through non-conventional energy transfer
2Manufacturing precision
If additives are used to replace gluten, then the rheological properties improve, but the product complexity and cost increase
Solution Approach 1:
The patent extracts and eliminates gluten and its substitutes from the formulation entirely, achieving gluten-free products with proper rheological properties through physical colloidal processing and microwave cooking rather than chemical additives
Solution Approach 2:
The patent creates a composite colloidal system combining gluten-free flours, starches, fibers, and enzymes in specific proportions, processed into a colloidal dispersion with controlled particle size (10-100 nm) to achieve gluten-like rheological properties without using gluten substitutes
3Manufacturing precision
If ultra-fine wet grinding and colloidal processing are used, then the texture and organoleptic properties improve, but the manufacturing time and energy consumption increase
Solution Approach 1:
The patent employs continuous ultra-fine wet grinding to create a colloidal dispersion, followed by continuous microwave cooking and drying in one integrated process, minimizing idle time and maintaining productive action throughout the manufacturing cycle
Solution Approach 2:
The patent uses microwave radiation (electromagnetic energy) instead of conventional thermal processing, enabling faster and more efficient cooking and drying of the colloidal dough, reducing the time required to achieve proper texture and moisture content (40-60%)
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 method produces gluten-free products with a pleasant texture, airy center, crispy crust, and appropriate moisture content, mimicking the qualities of gluten-containing baked goods, thereby addressing the limitations of existing gluten-free products.
Implementation Method 1
performing baking for the initial cooking and drying of the pieces of extruded colloidal dough in a microwave oven of between 2.45 GHz and 9.15 GHz for between 2 and 25 minutes until the moisture content of the pieces of extruded colloidal dough is between 40% and 60% and the temperature of the mentioned pieces is between 80°C and 95°C
Implementation Method 2
aerating the colloidal dispersion, obtaining a colloidal dough
Implementation Method 3
performing ultra-fine wet grinding of the pre-dough, obtaining a colloidal dispersion, in which the size of the solid particles is comprised between 10 and 100 nanometers
Implementation Method 4
performing baking for the final cooking of the pieces of semi-finished bakery and patisserie products in a radiation oven heated by convection and conduction
Implementation Method 5
performing baking for the final cooking of the pieces of semi-finished bakery and patisserie products in a radiation oven heated by convection and conduction for a time between 2 and 25 minutes, obtaining pieces of finished bakery and patisserie products with a moisture content between 0% and 40%

AI summary
The invention relates to a method for producing gluten-free bakery and patisserie products and to the gluten-free bakery and patisserie products obtained, the method facilitating natural baking by means of the addition of between 60 and 110% of water to the mixture of ingredients, owing to the high water requirements of fibres that act as substitutes for the gluten in traditional baking, and the production of an oxygenated colloidal dough from this hydrated dough, to facilitate, when applicable, the subsequent leavening thereof, during and after the production of the colloidal dough. The leavened or unleavened gluten-free bakery and patisserie products obtained have organoleptic and rheological proprieties similar to those of products with gluten.
