KEMUNDURAN KESEGARAN SELAMA PERKEMBANGAN CHILLING INJURY PADA PENYIMPANAN DINGIN BUAH TOMAT

Kesegaran merupakan istilah yang digunakan untuk mendefinisikan kondisi produk segar seperti buah dan sayur mendekati kondisi setelah panen. Parameter yang paling sering digunakan untuk menilai kesegaran di tingkat distributor, pasar atau supermarket adalah warna, aroma, mengkilat, dan kekerasan. Akan tetapi variable lainnya seperti kebocoran ion yang disebabkan oleh kerusakan dingin belum menjadi perhatian saat ini. Adapun tujuan dari penelitian ini adalah untuk mengidentifikasi kemunduran kesegaran buah tomat berdasarkan perkembangan kerusakan dingin selama penyimpanan dingin. Dari penelitian yang telah dilakukan didapatkan hasil bahwa berdasarkan produksi CO2 dan perubahan warna, buah tomat yang disimpan pada suhu 2ºC tidak mengindikasikan terjadinya kemunduran kesegaran karena produksi CO2 yang rendah yaitu 0,2 di awal penyimpanan dan dapat dipertahankan menjadi rendah sekitar 0,5 mmol kg/jam hingga hari ke 27 penyimpanan. perubahan warna menunjukkan warna tidak berubah menjadi warna merah pekat di hari ke Sembilan. Berdasarkan kebocoran ion, kerusakan dingin telah terjadi yang ditandakan dengan persentase kobocoran ion yang tinggi pada hari ke-27.
