Seed Kernel Processing for Allergen-Free Dairy Alternatives
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current dairy alternatives often contain common allergens like tree nuts, coconuts, soy, and sesame, making them unsuitable for individuals with allergies, and are often low in protein and high in carbohydrates, while there is a need for sustainable and nutritious food sources that address lactose intolerance and health concerns.
Innovation Solution
A method of processing sunflower seed kernels and other seeds, nuts, grains, and legumes at controlled temperatures and pressures to inactivate enzymes and preserve chlorogenic acid, resulting in a non-roasted seed base that can be used to create dairy-free products free from the top 14 recognized allergens.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If conventional processing techniques are used to prepare dairy alternatives, then protein content is reduced and carbohydrate content increases, but using alternative ingredients like tree nuts, coconuts, soy, and sesame introduces common allergens
Solution Approach 1:
The patent applies parameter changes by controlling cooking temperature (180-270°F), pressure (8-15 psi), water-to-feedstock ratio (1:1 to 6:1), and time (5-75 minutes) to optimize the processing of sunflower seed kernels. These parameter changes enable enzyme inactivation and chlorogenic acid preservation while maintaining high protein content and avoiding allergen introduction, thus resolving the contradiction between nutritional quality and allergen avoidance
2Ease of operation
If enzymatic treatment is applied to oats to improve digestibility, then simple sugar content increases, but this compromises the health benefits for diabetes management
Solution Approach 1:
The patent extracts and eliminates harmful factors by specifically targeting and inactivating enzymes that convert complex starches to simple sugars. Through controlled thermal processing, the patent removes the enzymatic activity that would otherwise increase simple sugar content, while still achieving digestibility improvements through other means such as starch gelatinization, thus resolving the contradiction between ease of digestion and health benefits
3Reliability
If pasteurization is used to ensure safety of plant-based milk alternatives, then beneficial enzymes and nutrients are destroyed, but without pasteurization, pathogenic microorganisms remain
Solution Approach 1:
The patent applies parameter changes by using lower temperatures (180-270°F compared to conventional pasteurization temperatures), controlled pressure (8-15 psi), and optimized time (5-75 minutes) to achieve microbial safety while preserving beneficial enzymes and nutrients. This modified thermal processing regime selectively inactivates harmful microorganisms and detrimental enzymes while maintaining the integrity of heat-sensitive nutrients, thus resolving the contradiction between microbial safety and nutrient preservation
4Reliability
If high heat treatment is applied to inactivate enzymes, then enzyme activity is reduced, but chlorogenic acid degrades and color changes occur
Solution Approach 1:
The patent applies parameter changes by precisely controlling the temperature range (180-270°F), pressure (8-15 psi), and time (5-75 minutes) to achieve enzyme inactivation while preserving chlorogenic acid. These parameter changes create a processing window that is sufficient to denature enzymes but insufficient to degrade chlorogenic acid, thus resolving the contradiction between enzyme inactivation and chlorogenic acid preservation
