AI Technical Summary
Existing technologies are unable to effectively utilize eggshells and organic waste from fruits and vegetables, leading to environmental pollution and resource waste. At the same time, existing processes for preparing organic calcium are complex, costly, and have low calcium conversion rates, making it difficult to achieve industrial application.
By employing a mixed-ingredient and aerobic fermentation process, a compound inoculant of lactic acid bacteria and photosynthetic bacteria is used to convert calcium carbonate in eggshells into water-soluble organic calcium acid. Combined with fruit and vegetable waste as a carbon source and nutrients, efficient conversion is achieved through a simple fermentation process.
This technology enables the high-value utilization of eggshells and fruit and vegetable waste, producing enzyme-based organic acid calcium products with good water solubility and high bioavailability. These products are suitable for agriculture and animal husbandry, and have both environmental and economic benefits.
