Increasing the shelf life of fresh-cut fruits and vegetables

Introduction

The convenience of pre-cut fresh vegetables and fruits is reshaping both home cooking and commercial kitchens. With more consumers opting for pre-cut produce to save time, the need for quality and freshness has become paramount. However, with rising demand comes the challenge: how can we extend the shelf life of pre-cut produce while ensuring safety and quality?

This question becomes even more critical for commercial operations that rely heavily on these products. Without proper handling and preservation, pre-cut fresh fruits and vegetables such as tomatoes, onions, and cucumbers are prone to contamination and spoilage.

Problem

Pre-cut fresh produce is especially vulnerable to contamination. Factors like handling, contact with surfaces, and packaging can expose fruits and vegetables to microbes, leading to quick spoilage. The high moisture content and nutrients present on the surface of cut produce create an ideal environment for bacterial growth, even under refrigeration. This leads to faster spoilage, wastage, and potential foodborne illnesses.

For businesses in the food industry, finding ways to implement solutions that prolong the shelf life of fruits and vegetables while maintaining food safety is crucial. The goal is to reduce food spoilage and wastage while ensuring the highest quality standards.

Solution

At MicroGO, we provide a comprehensive solution aimed at ensuring the shelf life extension for fruits & vegetables, making them safer for consumers and better for the environment. Our approach focuses on the critical factors involved in extending shelf life, from disinfection to temperature control. Below are the key elements that contribute to the successful preservation of pre-cut produce.

Key Factors for Shelf Life Extension

1. Choice of Biocide:

The effectiveness of the biocide used is crucial for eliminating pathogens, particularly those with antibiotic resistance mechanisms. To extend shelf life, the biocide must employ multiple killing mechanisms to manage microbial loads without leaving harmful residues. A food-grade biocide ensures safety for both humans and the environment.

2. Concentration

Proper concentration of the biocide is essential. Insufficient concentration might not achieve the desired antimicrobial effect, while excessive levels may leave harmful residues. Striking the right balance is key for achieving longer shelf life without compromising the quality of the produce.

3. Time

The duration of exposure to the biocide determines how effectively it disinfects the cut produce. Precise exposure times are critical for achieving shelf life extension without damaging the organic nature of fruits and vegetables. Incorrect exposure may allow microbes to survive and later rejuvenate, undermining the process.

4. Temperature

The temperature during treatment also plays a significant role in the effectiveness of the biocide. Post-treatment storage at refrigeration temperatures (0-4°C) helps maintain freshness and slows down microbial growth, further prolonging the shelf life of fruits and vegetables.

Note: The image shows the treated fruit and vegetables in 4° C storage for 5 days. The TPC, Y&M, and Enterobacteria are within acceptable limits after 5 days of storage.

Conclusion

By optimising biocide concentration, exposure time, and temperature, we can significantly reduce food spoilage and ensure a longer shelf life for pre-cut fresh produce. This not only ensures food safety and quality but also meets the growing demand for fresh, pre-cut fruits and vegetables while contributing to sustainability efforts in reducing food waste.
