How Are Chilean Cherries Kept Fresh During Transport to China?From November to February each year, Chile’s cherry harvest season peaks, with large volumes of fresh cherries exported to China via sea or air freight. To ensure the fruit arrives plump, juicy, and fresh, a multi-layered cold-chain system is employed throughout the logistics process.Immediately after harvesting—within hours—the cherries are rushed to pre-cooling facilities where they’re chilled to 0–2°C using either hydrocooling or forced-air cooling. This rapid cooling slows respiration and inhibits microbial growth. The cherries then undergo rigorous sorting, cleaning, and grading before being packed in food-grade films or modified atmosphere packaging (MAP), which adjusts internal oxygen and carbon dioxide levels to delay ripening.During transit, the cherries are loaded into temperature-controlled refrigerated containers that maintain a steady 0°C environment, monitored in real time for temperature and humidity. Sea freight typically takes 20–30 days, while air freight delivers the fruit in just 1–2 days—at a higher cost but with superior freshness and appearance.Moreover, China and Chile have established fast-track customs clearance and quarantine procedures, minimizing port dwell time and preserving quality. Thanks to this integrated farm-to-table cold chain, Chinese consumers can enjoy fresh, premium cherries from the Southern Hemisphere even in the middle of winter.
智利车厘子运到中国是如何保鲜的？每年11月至次年2月是智利车厘子的产季，大量新鲜车厘子通过海运或空运出口至中国。为确保果实抵达时依然鲜嫩多汁，整个物流链采用了多重保鲜技术。首先，在采摘后几小时内，车厘子会被迅速送入预冷车间，通过冷水或强制风冷将果温降至0–2℃，有效抑制呼吸作用和微生物生长。随后，果实经过严格分拣、清洗和分级，并采用食品级保鲜膜或气调包装（MAP），调节包装内氧气与二氧化碳比例，延缓成熟过程。在运输环节，车厘子被装入恒温冷藏集装箱，全程维持0℃左右的低温环境，并配备实时温湿度监控系统。海运通常耗时20–30天，而空运仅需1–2天，虽然成本更高，但能最大程度保留口感和外观。此外，中智两国已建立快速通关和检验检疫绿色通道，缩短口岸停留时间，减少品质损耗。正是这套从田间到餐桌的全程冷链体系，让中国消费者即使在冬季也能品尝到来自南半球的新鲜车厘子。
