Pengaruh pencelupan dalam ekstrak jahe, kondisi atmosfir dan lama penyimpanan terhadap mutu polong ercis muda.

BAHASA: Penelitian ini bertujuan mendapatkan cara dan kondisi penyimpanan dingin polong ercis muda agar berdaya simpan lama dan bermutu ekspor. Statistik yang digunakan dalam penelitian ini adalah Rancangan Acak Kelompok yang terdiri atas 8 perlakuan yang masing-masing diulang 3 kali. Perlakuan yang dicoba adalah polong ercis tanpa dicuci, dicuci dengan air, dicelup dalam ekstrak jahe dan dicuci air diikuti pencelupan dalam ekstrak jahe, dikombinasikan dengan penyimpanan pada komposisi udara biasa dan 2 persen O2 + 5 persen CO2. Hasil penelitian memperlihatkan bahwa polong ercis muda yang tanpa dicuci air dan ditempatkan dalam wadah berisi udara biasa, ternyata tahan simpan selama 28 hari pada suhu 5,5 derajat C. Setelah dikeluarkan dari ruang penyimpan suhu rendah, polong ercis muda masih segar dan hanya mengalami 2,8 persen susut bobot, dengan mutu baik dan belum mengalami kebusukan. Hasil analisis kimia menunjukkan bahwa polong ercis muda mengandung 9,7 persen PTT, 5,5 mg/100 g total asam, 31,8 mg/100 g vitamin C dan 78 persen kadar air. Penyimpanan lanjutan pada kondisi kamar menunjukkan bahwa polong muda hanya tahan simpan selama tiga hari. Hasil penelitian ini dapat diaplikasi dalam pengumpulan polong ercis muda atau penyimpanan untuk mengurangi kerugian pada saat harga jual rendah.

English. The objective was to study the effect of ginger extract dipping and atmosphere conditions on the quality of young sweet pea pod during storage. The study was conducted at ASEAN Berastagi Packing House Laboratory from August 1993 to March 1994, by applying a Randomized Block Design with 8 treatments and three replicates. The young sweet pea was unwashed, washed with tap water, dipped in an extract ginger solution and washed with tap water followed by dipping in an extract ginger solution, combined with placing in a container contained ordinary atmosphere and 2 percent O2 + 5 percent CO2. The results showed that the unwashed young sweet pea placed in a sealed container filled with ordinary air, maintained the pod quality for 28 days at 5.5 degree C. After removal from the storage chamber, the pod was still in fresh condition with 2.8 percent loss weight and of good pod quality and did not encounter any deterioration and contained 9.7 percent TSS, 5.5 mg/100 g of total acidity, 31.8 mg/100 g vitamin C and 78.8 percent moisture. Continued storage at ambient conditions after removal from cold storage, indicated that the quality of the pod was maintained for 3 days. The storage stability of young sweet pea pod for 28 days at such storage conditions, indicated that in order to collect the required amount or to minimize loss during low selling price, the pea pod can be stored as long as 28 days period. But after storage, the pea pod should be immediatelly sold due to its short quality stability after placed at ambient conditions.
