Aseptic Coconut Water Processing via Microfiltration and Thermal Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for sterilizing coconut water, such as high heat treatment and filtration, often destroy nutritional benefits and alter the flavor, failing to provide a stable, safe, and naturally tasting product.
Innovation Solution
Heating coconut water to 50° C. to 100° C. and filtering through two microfilters with 0.2 micron pore size to remove Clostridium botulinum spores while maintaining flavor, using a combination of macro and microfiltration processes to ensure microbial removal and minimize spoilage risk.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If high heat treatment is used for sterilization, then microbial safety is improved, but nutritional benefits and flavor are destroyed
Solution Approach 1:
The patent changes the sterilization parameters from traditional high heat prolonged treatment to a specific temperature range (50-100°C) with controlled duration (1-2 minutes), achieving microbial safety while preserving nutritional and flavor properties through optimized parameter control
Solution Approach 2:
The patent combines thermal treatment with physical filtration (microfilters with 0.2 micron pore size) to achieve sterilization, replacing pure thermal sterilization with a combined approach that better preserves product qualities while ensuring safety
2Reliability
If filtration and chilling are used for sterilization, then microbial safety is improved, but taste is negatively altered
Solution Approach 1:
The patent optimizes the filtration temperature parameter to 50-100°C (above ambient but below boiling), which prevents taste alteration associated with cold filtration while maintaining effective microbial removal through the microfiltration system
3Reliability
If prolonged high heat treatment is used, then sterilization effectiveness is improved, but flavor profile and nutrition are destroyed
Solution Approach 1:
The patent applies a rapid heating and filtration process (1-2 minutes at 50-100°C) that quickly achieves sterilization effectiveness without prolonged exposure, thereby skipping the detrimental prolonged heating phase that would destroy flavor and nutritional composition
Solution Approach 2:
The patent maintains continuous heating and filtration action throughout the brief 1-2 minute period to ensure consistent sterilization effectiveness, eliminating the need for prolonged intermittent treatment that would compromise product composition
