Low-Temperature Perilla Oil Processing to Suppress Coagulation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Perilla oil is prone to rancidity and generates coagulated suspended materials during low-temperature cold storage, leading to an unpleasant eating experience and the formation of harmful carcinogens like trans-fatty acids and benzopyrene, which limits its shelf life and consumer acceptance.
Innovation Solution
A method involving drying perilla seeds with hot air, expressing oil at low temperatures, and filtering to minimize moisture content and prevent the formation of carcinogenic substances, ensuring the oil is treated below 25°C to prevent coagulation and maintain quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of stationary object
If perilla oil is stored at low temperature to extend shelf life and prevent rancidity, then storage period is improved, but coagulated suspended materials are generated causing unpleasant eating experience
Solution Approach 1:
The patent applies preliminary action by conducting low-temperature treatment (0-25°C) and filtration before storage to remove substances that would coagulate during cold storage. This pre-treatment prevents the formation of suspended materials while maintaining the oil's stability during extended storage periods.
Solution Approach 2:
The patent changes temperature parameters by treating the oil at low temperatures (0-25°C) before storage and controlling storage conditions. This parameter change prevents coagulation while extending shelf life, resolving the contradiction between storage duration and quality maintenance.
2Object-generated harmful factors
If perilla oil is roasted at high temperature to enhance flavor, then taste quality is improved, but carcinogenic substances like benzopyrene and trans-fatty acids are generated
Solution Approach 1:
The patent changes the temperature parameter from high-temperature roasting to low-temperature expression (0-60°C). This parameter change eliminates carcinogenic substance formation while still producing perilla oil with acceptable flavor through alternative processing methods.
Solution Approach 2:
The patent replaces thermal processing (roasting) with mechanical processing (cold pressing/expression). This substitution removes the source of carcinogenic substances while maintaining oil production and flavor development through mechanical means rather than thermal means.
3Manufacturing precision
If perilla oil is filtered multiple times to remove suspended materials, then oil clarity is improved, but production time and complexity increase
Solution Approach 1:
The patent applies preliminary low-temperature treatment before filtration to prevent coagulation during the filtration process. This preliminary action simplifies the overall filtration process by ensuring materials remain dispersed, reducing the need for multiple complex filtration steps.
Solution Approach 2:
The patent uses low-temperature treatment as an intermediary step that facilitates easier filtration. By maintaining low temperature throughout the process, the oil's components remain in a state that allows for simpler, more efficient filtration with fewer stages.
