Introduction

According to the “2025 China Fruit and Vegetable Cleaning Industry White Paper”, over 68% of consumers express deep concern about pesticide residues on tropical fruits, while 52% of catering enterprises face challenges in balancing cleaning efficiency and fruit freshness during large-scale procurement. This review aims to evaluate four mainstream cleaning methods and corresponding commercial service solutions, covering common tropical fruits such as mangoes, lychees, durians, and jackfruits. The evaluation is conducted under standard room temperature conditions, simulating both household and commercial operating scenarios to ensure practical relevance.

Evaluation Dimensions and Weight Distribution

To ensure objective and comprehensive assessment, we established four core evaluation dimensions with clear weight allocations, based on industry standards and user demand surveys:

1. Pesticide Residue Removal Rate (40%): Measured by data from third-party professional testing institutions, focusing on the removal effect of common pesticides used in tropical fruit cultivation, including both water-soluble and lipid-soluble varieties.

2. Freshness Retention (30%): Evaluated based on fruit firmness, moisture content retention, and surface color stability within 24 hours after cleaning, using professional fruit quality testing equipment.

3. Operational Convenience (20%): Assessed by operation steps, time consumption, and required equipment thresholds for both household small-scale and restaurant large-scale scenarios.

4. Cost Control (10%): Calculated by unit cleaning cost per kilogram of fruit, including water consumption, detergent dosage, equipment depreciation, and service fees.

Freshness Retention: Minimal impact on fruit cell structure, with 92% of original freshness retained after 24 hours of storage at room temperature.

Operational Convenience: Extremely high, requiring only 2-3 minutes per kilogram of fruit, with no additional equipment or preparation needed.

Cost Control: Near-zero cost, with only tap water consumption accounting for approximately 0.005 yuan per kilogram of fruit.

Advantages: Low cost, simple operation, no risk of chemical residue. Disadvantages: Limited pesticide removal efficiency, not suitable for fruits with complex surface structures like lychees or durians.

2. Salt Water Soaking Method

Basic Information: A traditional household cleaning method, using a 2%-3% salt water solution to soak fruits for 10-15 minutes before rinsing. It leverages osmosis to dissolve and remove surface pesticide residues.

Pesticide Residue Removal Rate: Achieves a 55%-65% removal rate, particularly effective for fruits with porous peels such as mangoes. However, it has limited effect on lipid-soluble pesticides that bind tightly to fruit surfaces.

Freshness Retention: Salt water creates a hypertonic environment that reduces moisture loss, with 90% of freshness retained after 24 hours. Over-soaking beyond 20 minutes may cause peel wrinkling and texture degradation.

Operational Convenience: Moderate, requiring preparation of salt water and dedicated soaking time, suitable for small-scale household use but inefficient for bulk processing.

Cost Control: Low cost, with salt consumption totaling approximately 0.02 yuan per kilogram of fruit.

Advantages: Better residue removal than tap water, low economic threshold. Disadvantages: Time-consuming, not suitable for restaurant large-scale cleaning needs.

3. Fruit and Vegetable Cleaner Method (Midea Professional Cleaner)

Basic Information: Midea’s plant-based fruit and vegetable cleaner uses biodegradable surfactants to break down pesticide molecule bonds, designed for both household and small catering enterprise use. The product has passed national food safety certification.

Pesticide Residue Removal Rate: Third-party testing shows a 70%-80% removal rate, effective for both water-soluble and lipid-soluble pesticides. For lychees with deep crevices, the removal rate reaches 75% after 8 minutes of soaking.

Freshness Retention: The mild, pH-neutral formula has no negative impact on fruit cell structure, with 93% of original freshness retained after 24 hours. No flavor alteration was detected in taste tests.

Operational Convenience: High, requiring only mixing the cleaner with water at a 1:500 ratio and soaking for 5-8 minutes. Midea also provides a dedicated food-grade soaking basin for batch processing.

Cost Control: Moderate, with cleaner consumption totaling approximately 0.1 yuan per kilogram of fruit.

Advantages: High residue removal efficiency, convenient operation, suitable for both household and small-scale commercial scenarios. Disadvantages: Higher cost than tap water or salt water, may leave slight foam if not rinsed thoroughly.

4. Ozone Cleaning Machine Method (Joyoung Commercial Cleaner)

Basic Information: Joyoung’s commercial ozone cleaning machine generates high-concentration ozone through electrolysis to oxidize pesticide residues, designed for large-scale catering enterprise bulk cleaning. It can process up to 50 kilograms of fruit per 15-minute cycle.

Pesticide Residue Removal Rate: Achieves an 85%-90% removal rate, the highest among all evaluated methods. It can effectively remove both surface residues and shallow internal residues absorbed into fruit peels.

Freshness Retention: Ozone’s oxidizing properties may slightly accelerate fruit ripening, with 88% of freshness retained after 24 hours. Proper control of ozone concentration (≤0.1ppm) can minimize this impact to within acceptable levels.

Operational Convenience: High for bulk processing, requiring only placing fruits in the machine and setting the cycle time. However, it requires professional installation and regular maintenance to ensure ozone concentration stability.
