控制摊放高度温度预贮3-4天，能有效增加柑橘保鲜时间

Core Insights - The article discusses the importance of post-harvest preservation techniques for citrus fruits and edible fungi, emphasizing the need for improved quality control to prevent economic losses due to spoilage and degradation. Group 1: Citrus Preservation Techniques - Citrus fruits have strict environmental requirements for preservation, including sensitivity to temperature, humidity, and gas composition, which affects their storage life and quality [5] - Effective orchard management, careful harvesting, and appropriate storage conditions are essential to prevent pathogen growth and maintain fruit quality [5] - The recommended harvesting times for different citrus varieties are: early maturing types around late August, early maturing oranges in early November, mid-maturing types from mid-November to late December, and late maturing types from early January to late June [6][5] - Pre-storage treatments such as washing and using preservatives can extend the storage period, with ideal pre-storage conditions being 6°C-8°C and 75% relative humidity [6] Group 2: Preservation Technologies - Common preservation technologies for citrus include low-temperature storage, modified atmosphere storage, waxing, irradiation, and the use of antimicrobial agents [7] - New preservation methods developed include self-regulating gas preservation bags and various types of preservation packaging [7] - Citrus processing can yield over 1,000 products, with orange juice being the most significant, followed by canned fruit, candied products, and alcoholic beverages [7] Group 3: Edible Fungi Preservation - Maintaining the vitality of edible fungi is crucial for their storage life and disease resistance, achieved by reducing respiration and transpiration rates [8] - Pre-cooling, packaging, and modified atmosphere storage are effective methods for preserving fresh edible fungi [9] - The recommended storage temperature for edible fungi is between 0°C-4°C, with relative humidity levels of 80%-90% [9] Group 4: Packaging and Processing - Packaging methods such as "moisture-regulating bags + high-performance absorbent materials + insulated boxes" can maintain the quality of mushrooms during transportation [11] - Various processing techniques for edible fungi include drying, salting, and canning, which enhance their nutritional value and marketability [14]
