Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is no established method for transforming agricultural products grown in controlled environments with reduced carbon-14 (14C) content into consumable food and beverage products, which are essential for minimizing DNA damage and potential health risks associated with natural 14C abundance in the food chain.
Innovation Solution
A process involving the growth of agricultural products in controlled environments with filtered atmospheric gases or CO2 from sources with lower 14C abundance, followed by harvesting, washing, extraction of edible components, pre-drying, freeze drying, post-drying, and packaging to create dehydrated consumable products that reduce 14C content and minimize transportation costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If agricultural products are grown in controlled environments with filtered atmospheric gases to reduce 14C content, then health benefits from minimized DNA damage are achieved, but production complexity and cost increase
Solution Approach 1:
The process segments the production into distinct stages: growing agricultural products in controlled environments with filtered CO2, harvesting, washing, extraction, pre-drying, freeze-drying, post-drying, and packaging. This segmentation allows each stage to be optimized independently for reducing 14C content while managing complexity.
Solution Approach 2:
The patent applies preliminary action by pre-filtering atmospheric gases to remove CO2 and pre-freezing products before drying. The CO2 is removed in advance from the controlled environment, and products are pre-frozen to facilitate subsequent freeze-drying, which efficiently reduces 14C content while maintaining product quality.
2Weight of moving object
If agricultural products are processed into dehydrated consumable products, then transportation cost is reduced, but processing time and energy consumption increase
Solution Approach 1:
The patent utilizes phase transitions in the freeze-drying process where water in the agricultural products is frozen and then sublimated from solid to gas phase. This removes approximately 90% of the product weight (water content) while preserving the product structure and minimizing 14C content, making transportation significantly more efficient.
Solution Approach 2:
The patent replaces conventional thermal drying with freeze-drying, which uses phase transition physics instead of purely thermal mechanical processes. This substitution preserves heat-sensitive nutrients and 14C-reduced qualities better while achieving the same weight reduction for transportation efficiency.
3Duration of action of stationary object
If freeze drying is used for dehydration, then shelf-life is extended and product quality is maintained, but energy consumption and processing time increase
Solution Approach 1:
The freeze-drying process exploits the phase transition of water from solid to vapor without passing through the liquid phase. This creates a product with minimal moisture content and preserved structural integrity, extending shelf-life significantly while maintaining nutritional quality and 14C reduction benefits.
Solution Approach 2:
The freeze-drying process operates in periodic cycles: freezing phase, primary drying (sublimation), and secondary drying (desorption). This periodic action allows efficient removal of water while preserving product quality and extending shelf-life, making the energy investment worthwhile for the extended storage capability.

AI summary
This invention provides a process to prepare consumable food and beverage products with reduced carbon-14 (14C) content. Normal agricultural products capture carbon-dioxide (CO2) with radioactive 14C from atmospheric gases. Agricultural products grown in controlled environments such as a greenhouse with filtered atmospheric gases to remove CO2 with 14C can be harvested and processed into readily consumable products that omit the damage to human DNA that is unavoidable with our current food chain. This process provides food and beverage products with a lower than natural abundance of TAC for consumption.
