| dc.description | Pasta tomat kental merupakan salah satu bentuk olahan konsentrat buah tomat dengan total padatan terlarut tinggi sehingga bersifat kurang voluminous dan memudahkan transportasi serta distribusinya. Untuk menjamin bahwa pasta tomat belum mengalami kerusakan sampai di tangan konsumen, maka diperlukan informasi tentang masa simpan. Salah satu cara untuk menduga umur simpan secara cepat adalah dengan metode Accelerated Storage Studies (ASS) melalui pendekatan metode Arhenius. Ada empat produk pasta tomat yang diduga umur simpannya yaitu K (kontrol: pasta tomat tanpa bahan tambahan), P (pasta tomat ditambah pengawet), PP (pasta tomat ditambah pengawet dan pewarna), PPG (pasta tomat ditambah pengawet, pewarna dan gula). Pasta tomat disimpan dalam tiga suhu yakni suhu 40°C, suhu kamar (28°C) dan ruangan berpendingin udara (20°C). Penelitian diulang sebanyak tiga kali. Analisis dilakukan terhadap parameter mutu kritis yaitu tingkat kecerahan warna dan penerimaan. Analisis dilakukan setiap dua minggu selama delapan minggu penyimpanan. Pasta tomat dengan parameter kritis tingkat kecerahan warna, kontrol mempunyai dugaan umur simpan yang paling lama yaitu pada penyimpanan suhu 7°C, 15°C, 2YC dan 30°C masing-masing mempunyai dugaan umur simpan sebesar 97,93 : 91,90; 85,29 dan 82,32 hari. Sementara berdasarkan parameter kritis penerimaan konsumen, PPG (pasta tomat dengan penambahan pengawet, pewarna dan gula) mempunyai dugaan umur simpan paling lama, pada penyimpanan suhu 7°C, 15°C, 25°C dan 30°C masing-masing mempunyai dugaan umur simpan sebesar 87,72 ; 54,41; 31,05 dan 23,78 hari. Shelf Life Prediction Of Heavy Tomato Paste In Plastic Bottle Using Accelerated Storage MethodHeavy tomato paste is a concentrated product having high total soluble solid (TSS) so that it is less voluminous easy for transportation and distribution. Information on product shelf life is required to ensure that product is recei ved by consumers in excellent condition. An accelerated storage studies (ASS) with Arrhenius model was developed to predict the product shelf life. Four different types of product were employed in this study, i.e. tomato paste without preservatives and colourants (K), tomato paste with preservatives (P), tomato paste with preservatives and colourants (PP), and tomato paste with preservatives, colourant and sugar (PPG). The products were kept at 40"C, 28°C and 20°C, and the experiments were done in triplicates. Parameters observed were colour lightness and consumers acceptance. The product were analysed every two weeks for eight weeks of storage. In term of colour ligtness, K had the longest predicted shelf life at 7°C, 15°C, 25°C and 30°C with the shelf lives 97.93 : 91.90; 85.29 and 82.32 days, respectively. PPG had the longest predicted shelf life in terms of consumers acceptance at 7°C, 15'C, 25°C, 30'C with the shelf lives 87.72 ; 54.41, 31.05 and 23.78 days, respecttively. These results were confirmed with results of normal storage experiments. | en-US |
