Plant-Based Milk Emulsification System for Flavor Preservation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The commercial production of plant-based milk, such as nut milk, faces challenges due to high heat processing that degrades flavor and texture, and the need for refrigeration, as well as difficulties in producing pure, preservative-free beverages that are perishable and prone to separation, leading to inconsistent quality and short shelf life.
Innovation Solution
A system and method for emulsifying plant-based paste with water on demand, using a mixing chamber configured to form a stable emulsion, which includes a pumping system, a cooling system, and a control system to dispense the emulsified mixture, allowing for fresh production and distribution without refrigeration, thereby addressing separation issues and improving product quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If commercial high heat processing is used to produce plant-based milk, then production efficiency is improved, but flavor, color, and smell are degraded
Solution Approach 1:
The patent changes the temperature parameter from high heat (135°C) to low temperature processing, fundamentally altering the processing conditions to preserve sensory qualities while maintaining production efficiency through continuous low-temperature operation
Solution Approach 2:
The patent replaces thermal processing with mechanical homogenization and emulsification systems, using mechanical energy instead of thermal energy to achieve proper mixing and stability without heat-induced degradation of flavor and aroma compounds
2Ease of manufacture
If water-based plant-based milk is produced for commercial distribution, then ease of manufacture is improved, but refrigeration is required increasing complexity
Solution Approach 1:
The patent introduces fat-soluble vitamins and emulsifiers as intermediary substances that enable the product to remain stable and shelf-stable without refrigeration, acting as mediators between the water-based formulation and storage stability requirements
Solution Approach 2:
The patent changes the storage temperature parameter from refrigerated (cold chain) to ambient temperature storage, fundamentally altering the distribution and storage conditions to eliminate refrigeration requirements while maintaining product stability through formulation modifications
3Duration of action of stationary object
If preservatives are added to extend shelf life, then duration of action is improved, but product purity is reduced
Solution Approach 1:
The patent converts the naturally perishable nature of pure plant-based ingredients into a benefit by using the natural composition itself (including natural oils and plant compounds) as the preservation mechanism, eliminating the need for synthetic preservatives while extending shelf life through proper formulation and processing
Solution Approach 2:
The patent changes the chemical composition parameters by removing synthetic preservatives and relying on the natural composition of plant-based ingredients combined with low-temperature processing to achieve both purity and extended shelf life
4Ease of manufacture
If nut paste is stored at room temperature, then ease of storage is improved, but separation occurs reducing quality
Solution Approach 1:
The patent introduces emulsifiers and stabilizers as intermediary substances that prevent separation of fat and water phases in nut paste during storage, maintaining homogeneous composition without requiring refrigeration
Solution Approach 2:
The patent performs preliminary emulsification and stabilization processing before storage, creating a pre-stabilized product that resists separation during ambient temperature storage, eliminating the need for post-processing intervention
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 system enables the production of high-quality, fresh plant-based milk on demand, reducing waste and transportation costs by eliminating the need for refrigeration and preserving the natural flavor and texture, while ensuring consistent product quality and extended shelf life.
Implementation Method 1
a process of emulsifying these components, i.e., forming a stable emulsion of two or more components (e.g., paste and water) even when these components are immiscible
Implementation Method 2
a cooling system configured to cool water within the water storage to a first prescribed temperature and to cool contents of the mixing chamber to a second prescribed temperature

AI summary
A system for dispensing a plant-based milk includes a mixing chamber for emulsifying a plant-based paste and water, a plant-based paste storage connected to the mixing chamber via a first conduit, a water storage connected to the mixing chamber via a second conduit, and a cooling system. The system includes a pumping system for moving a prescribed amount of the plant-based paste into the mixing chamber upon receiving an input from a user via a user interface, a flow system for flowing water from the water storage to the mixing chamber, and a control system. The control system receives the input from the user, activates the pumping system and activates the flow system. Further, the control system activates the mixing chamber for emulsifying the plant-based paste and the water, and dispenses the emulsified plant-based mixture of the paste and the water.
