High-Fat Flour Replacement via Emulsion Extrusion
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Customers seek low-carbohydrate flour alternatives to wheat flour, but existing alternatives like almond flour are expensive, have supply issues, and raise environmental concerns.
Innovation Solution
A high-fat flour replacement is developed, comprising edible fats, an emulsifier, protein, and soluble fiber, processed to retain a high fat content while being dry in form, with a macronutrient profile similar to almond flour, using a combination of canola oil, sodium caseinate, soy protein, and soluble corn fiber, and produced through an emulsion formation and extrusion process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If almond flour is used as a flour alternative, then low carbohydrate content is achieved, but production cost increases and supply reliability decreases
Solution Approach 1:
The patent replaces expensive almond flour with a cost-effective blend of common ingredients including vegetable oils, eggs, proteins, and starches. This substitution uses inexpensive, readily available materials to achieve the desired low-carbohydrate flour alternative, directly addressing the high production cost issue while maintaining the low carbohydrate content.
Solution Approach 2:
The invention creates a composite flour replacement by combining multiple ingredients (vegetable oils, eggs, proteins, starches, and other components) in specific proportions. This composite approach achieves the macronutrient profile of almond flour while using cheaper, more sustainable ingredients, thereby reducing production cost and improving supply reliability.
2Quantity of substance
If high fat content is incorporated in the flour replacement, then macronutrient profile similar to almond flour is achieved, but the product becomes oily and difficult to handle
Solution Approach 1:
The patent uses eggs as an intermediary binding agent that emulsifies and stabilizes the high fat content from vegetable oils. The eggs prevent the fat from separating and creating an oily texture, allowing the flour replacement to maintain high fat content (30-60%) while remaining handleable and suitable for baking applications.
Solution Approach 2:
The invention carefully controls the physical state parameters of the fat component by selecting vegetable oils with appropriate melting points and combining them with solidifying agents. This parameter control ensures the fat remains in a manageable state during storage and handling while providing the desired high fat content and macronutrient profile.
3Ease of manufacture
If sustainable and cost-effective ingredients are used, then production cost decreases and sustainability improves, but product performance may deteriorate
Solution Approach 1:
The patent optimizes the macronutrient ratios of the ingredient blend to match almond flour's performance characteristics. By carefully adjusting the proportions of proteins, fats, carbohydrates, and fibers, the invention achieves comparable baking performance, texture, and nutritional profile using sustainable, cost-effective ingredients, thereby maintaining product reliability while reducing cost.
Solution Approach 2:
The composite formulation combines multiple functional ingredients that complement each other's properties. The synergistic interaction between proteins, fats, starches, and binding agents in the blend replicates the performance of almond flour, ensuring that product quality and reliability are maintained despite using alternative, more sustainable ingredients.

Function Achieved in This Case
The high-fat flour replacement is cost-effective, sustainable, and maintains a low carbohydrate content, suitable for various food products, preventing oiling out during manufacturing and providing a granular nature analogous to almond flour.
Implementation Method 1
forming an emulsion including a fat, water and an emulsifier
Implementation Method 2
the emulsion and the blend of dry ingredients are combined in an extruder
Implementation Method 3
the extruded material is then dried (e.g., to a moisture content below about 10%, or below about 5%, or to about 3.5%)

AI summary
A high-fat flour replacement includes a fat, an emulsifier, a protein, a starch and a soluble fiber. In preferred embodiments, the high-fat flour replacement is a finely ground particulate “flour”. The high-fat flour replacement can have a macronutrient profile analogous to that of almond flour. A process for producing a high-fat flour replacement includes a step of forming an emulsion including a fat, water and an emulsifier and a step of combining the emulsion with a blend of dry ingredients to form a composition (e.g., using an extruder). The blend of dry ingredients includes a protein, a starch and a soluble fiber. In preferred embodiments, the composition is processed in an extruder to form an extruded material (e.g., in the form of pellets). The fat in the emulsion becomes trapped in the composition during extrusion. In preferred embodiments, the extruded material is then dried and milled/ground to form flour-sized particulates.
