Description
Sari buah nanas merupakan sari buah yang digemari oleh masyarakat. Namun umur simpan sari buah nanas cukup singkat. Oleh karena itu dibutuhkan teknologi untuk memperpanjang umur simpan sari buah nanas. Penambahan sari cempedak pada sari buah nanas dapat memperbaiki umur simpan dan mutu sari buah nanas. Penelitian ini bertujuan untuk mempelajari pengaruh penambahan sari cempedak terhadap umur simpan dan kelayakan sari buah nanas. Bahan yang digunakan dalam penelitian ini yaitu buah nanas dan cempedak. Sari buah nanas dan nanas-cempedak disimpan pada suhu 15, 30 dan 450C selama 2 bulan. Pengamatan yang dilakukan terdiri atas vitamin C, total asam, total padatan terlarut, komponen flavor, rasa, aroma, warna dan kelayakan. Pendugaan umur simpan sari buah menggunakan metode Accelarated Shelf Life Test (ASLT). Hasil penelitian menunjukkan bahwa kandungan vitamin C, asam sorbat dan asetaldehida sari buah nanas cempedak lebih tinggi dibandingkan sari buah nanas. Umur simpan sari buah nanas-cempedak 41 hari lebih lama dibandingkan sari buah nanas. Sari buah nanas dan nanas-cempedak masih layak untuk dikonsumsi hingga 2 bulan.Kata kunci :Sari buah nanas, sari buah nanas-cempedak, umur simpan, nutrisiEnglish Version AbstractPineapple juice is a fruit juice that is favored by the people. The shelf life of pineapple juice is quite short. Therefore, it needs the technology to extend the shelf life of pineapple juice. The addition of cempedak juice at pineapple juice has expected to extend the shelf life and improve quality of pineapple juice. This research aimed to study the effect of the addition cempedak juice for shelf life of pineapple juice. The materials used in this research was the fruit of pineapple and Cempedak. Pineapple juice and pineapple- Cempedak were stored at the temperature of 15, 30 and 45 0C for 2 months. Observations were carried out on of vitamin C, total acid, total soluble solids, flavor compounds, taste, flavor, color and edibility. The estimation of shelf life for the juice used a method Accelarated Shelf Life Test (ASLT). The results showed that the content of vitamin C, sorbic acid and acetaldehyde pineapple-cempedak juice higher than pineapple juice. Shelf life of pineapple-cempedak juice was 41 days longer than pineapple juice. Pineapple juice and pineapple-cempedak juice was still fovorable for the consumption until 2 months.Keywords :pineapple juice, pineapple-cempedak mixed juice, shelf life, nutrition
