Plant-Based Dough Water Activity Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a lack of viable, all-natural, plant-based, and shelf-stable dough options that can be stored at non-refrigerated conditions without risk of contamination or spoilage, particularly for individuals with dietary restrictions, and existing doughs often contain ingredients prone to expiration that can lead to food-borne illnesses.
Innovation Solution
A method of preparing a dough using flaxseed meal, purified water, a flour blend, and a shortening-sugar compound, with specific weight ratios and mixing processes, to create a shelf-stable, plant-based dough with a water activity of less than or equal to 0.83, allowing it to be stored at ambient temperatures for extended periods without refrigeration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional dough ingredients (eggs, dairy, gluten) are used, then taste and texture quality are improved, but shelf stability and safety for individuals with dietary restrictions deteriorate
Solution Approach 1:
The patent changes the chemical and physical parameters of the dough by using alternative ingredients (flaxseed meal instead of eggs, coconut oil instead of dairy butter, gluten-free flour blends) and controlling water activity (aw ≤ 0.83) and pH (7.0-8.5) to achieve shelf stability without traditional allergenic ingredients
Solution Approach 2:
The patent creates a composite dough formulation combining multiple plant-based ingredients (flaxseed meal, coconut oil, gluten-free flours, starches, and gums) that work together to provide both dietary restriction compliance and extended shelf stability at ambient temperatures
2Object-affected harmful factors
If refrigeration is used to prevent spoilage, then food safety is improved, but storage space and shipping costs increase
Solution Approach 1:
The patent modifies the physical-chemical parameters of the dough system by controlling water activity (reducing to ≤ 0.83) and pH levels (7.0-8.5), which fundamentally changes the environment to be hostile to microbial growth, thereby eliminating the need for refrigeration and reducing energy costs
Solution Approach 2:
The dough formulation is designed to be self-preserving through its ingredient composition and controlled water activity, allowing it to maintain safety and quality at ambient temperatures without requiring external refrigeration infrastructure
3Reliability
If all-natural ingredients are used, then health benefits and consumer preference are improved, but shelf life and resistance to spoilage deteriorate
Solution Approach 1:
The patent applies parameter changes by precisely controlling water activity (aw ≤ 0.83) and pH (7.0-8.5) of the all-natural ingredient system, creating conditions that prevent microbial growth while preserving the natural health benefits of plant-based ingredients
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 resulting dough is safe from contamination and spoilage, suitable for consumption by individuals with dietary restrictions, and can be stored for at least 30 days without refrigeration, reducing shipping and storage costs while maintaining quality.
Implementation Method 1
allowing the flaxseed meal to reconstitute with the purified water to form a diluted flaxseed
Implementation Method 2
a water activity of less than or equal to 0.83, allowing it to be stored at ambient temperatures for extended periods without refrigeration

AI summary
The present disclosure is directed to compositions and methods of preparing a shelf-stable, plant-based, gluten-free dough (e.g., cookie dough) that can be stored in non-refrigerated conditions for a prolonged period without the need for time and/or temperature controls. Shelf stability is achieved based on the disclosure of compounds that have desired low moisture content and such that the dough, and methods of making the dough, regulate the water activity and pH to levels at which microbial growth is minimized or is otherwise prevented. The dough can use all-natural, organic, plant-based, and/or vegan ingredients to be devoid of preservatives and to be part of a healthy, balanced diet. Other aspects of the present disclosure, including various combinations of ingredients used and their relative proportions and ratios, and methods for combining the ingredients, are also provided.
