Summary
Iklim tropis telah menjadikan Indonesia sebagai sumber bagi ketersediaan berbagai jenis produk holtikultura terutama buah segar. Dirjen Hortikultura Kementerian Pertanian (2010) menyatakan bahwa tingkat konsumsi sayur dan buah masyarakat Indonesia saat ini masih rendah. Standar konsumsi yang direkomendasikan oleh Food and Agriculture Organization (FAO) yaitu 73 kilogram per kapita per tahun sedangkan di Indonesia saat ini tingkat konsumsi sayur dan buah hanya 40 kilogram per kapita per tahun. Badan Karantina Pertanian menyebutkan bahwa volume jeruk impor pada Januari-April 2011 sudah mencapai 50 persen dari total impor sepanjang 2010. Sampai saat ini Indonesia termasuk negara pengimpor jeruk terbesar kedua di ASEAN setelah Malaysia, dengan volume impor khususnya untuk jenis keprok atau mandarin, selama kurun waktu 2005 - 2010 mencapai 550.809 ton atau sekitar 91.802 ton per tahun dengan nilai mencapai US $ 650.128.774 (BPS, 2011). Mangga-mangga impor masuk ke Indonesia lantaran memberikan sesuatu yang sulit terpenuhi oleh mangga lokal, yakni rasa, kualitas, dan jaminan kontinuitas. Salah satu bentuk senyawa oksigen reaktif adalah radikal bebas, senyawa ini terbentuk di dalam tubuh dan dipicu oleh bermacam-macam faktor (Winarsi, 2007)
