Optical System Design and Analysis of 405 nm Light Source for Food Preservation

In today's world, where food security and safety are key issues, perishable food preservation is a big challenge. Food preservation techniques have advanced significantly throughout time, with traditional methods like canning, drying, and salting giving way to more modern methods like refrigeration and freezing. However, as the global population grows and the demand for fresh, safe, and nutritious food grows, so does the demand for novel, sustainable, and effective food preservation technology. According to the research, food prices have risen by 24.1% in the previous year, and food supply has begun to decrease. Another big issue is food waste. The globe creates 931 million tonnes of food waste each year. Light technologies of various wavelengths are being researched to discover solutions to these problems, as are attempts to ensure that foods can be preserved for longer periods of time.
