Abstract
Mango has a high nutritional value and is one of the most popular tropical fruits in the world (Sivakumar et al., 2011). Fresh mango fruit is also popular in Japan, marketed at a high price. Major mango production areas in Japan are located in Okinawa and Miyazaki in Kyushu. Total mango production in Japan was 3,664 tons in 2014 (MAFF, 2014), while a double amount of mango fruits (totaled 7,354 tons) were imported in 2014 (Japan fresh produce import-export and safety association, 2017). Of the imported mangoes, Mexico ranked the first in both amount (38.7%) and price (31.2%), followed by Philippines (17.7% in amount (ranked 2nd); 16.0% in price (ranked 4th)), Thailand (16.7% in amount (ranked 3rd); 19.8% in price (ranked 2nd)) and Taiwan (10.3% in amount (ranked 4th); 17.7% in price (ranked 3rd)). The Tokyo Customs reported (2015) that mango fruits were imported through the Narita airport (33.2%), the Port of Yokohama (23.8%), the Port of Tokyo (17.9%), and the Haneda Airport (16.7%), which exceeds 90% of total import in Japan. This report indicates that more than 40% of mango fruits were transported by ship in which postharvest quality loss is highly expected due to a long transportation time. However, little study has been conducted to assess the postharvest quality loss or ripening process of fresh mango fruits during a long distance distribution (Kienzle et al., 2011; 2012; Yasunaga et al., 2012; 2013a; 2013b). In our previous research, we have investigated the quality changes of fresh mango fruit before and after distribution (Yasunaga et al., 2013a), in which fruit quality at harvest were different between orchards in Thailand and Japan, mainly because of the distances to the final destination. While postharvest quality changes were reported, the results were limited to the two points in time, namely at harvest and after distribution. Because postharvest ripening is controlled by storage temperature, it is necessary to investigate the effects of temperature on the quality changes of fresh mango fruits exported for a long distance market. The objective of this study is to investigate the effects of storage conditions on the postharvest quality changes of fresh mango fruit exported from Thailand to Japan. In addition to the monitoring of distribution conditions, two laboratory experiments under three different temperature conditions (i.e., 15, 25 and 35°C) were conducted at before and after distribution to better understand postharvest ripening processes during long-distance transportation. Results are compared with respect to postharvest quality changes under different distribution conditions for a better quality control system of fresh mango fruit for export.
芒果营养价值高,是世界上最受欢迎的热带水果之一(Sivakumar et al., 2011)。新鲜的芒果在日本也很受欢迎,售价很高。日本主要的芒果产区位于冲绳和九州的宫崎。2014年日本芒果总产量为3664吨(MAFF, 2014),而2014年芒果进口量翻了一番(总计7354吨)(日本生鲜农产品进出口和安全协会,2017)。进口芒果中,墨西哥以数量(38.7%)和价格(31.2%)居首位,菲律宾以数量(17.7%)居第二位;价格(16.0%)(第4位)、泰国(16.7%)(第3位);价格(19.8%)(第2位)、台湾(10.3%)(第4位);17.7%(第3位))。据东京海关统计(2015年),芒果通过成田机场(33.2%)、横滨港(23.8%)、东京港(17.9%)、羽田机场(16.7%)进口,占日本进口总量的90%以上。该报告指出,超过40%的芒果果实是通过船舶运输的,由于运输时间长,收获后的质量损失是很有可能的。然而,很少有研究对新鲜芒果果实在长距离运输过程中的采后品质损失或成熟过程进行评估(Kienzle et al., 2011;2012;Yasunaga等人,2012;2013年;2013 b)。在我们之前的研究中,我们调查了新鲜芒果水果在分销前后的质量变化(Yasunaga et al., 2013),其中泰国和日本果园收获时的水果质量不同,主要是因为距离最终目的地的距离。虽然报告了采后质量变化,但结果仅限于两个时间点,即收获时和分配后。由于采后成熟受贮藏温度控制,因此有必要研究温度对出口长途市场的新鲜芒果果实品质变化的影响。本研究旨在探讨泰国出口日本的新鲜芒果果实采后品质变化与贮藏条件的关系。在对配送条件进行监测的基础上,在配送前后分别进行了15℃、25℃和35℃三种不同温度条件下的室内实验,以更好地了解采后长距离运输过程中的成熟过程。通过对不同流通条件下芒果采后品质变化的比较研究,为建立出口芒果鲜果质量控制体系提供依据。
