Penambahan ikan pari asap pada pembuatan sambal dapat menjadi alternatif pengolahan ikan pari asap dan menghasilkan sambal dengan cita rasa khas. Selama penyimpanan, sambal mengalami penurunan mutu secara mikrobiologi serta menyebabkan perubahan aroma dan timbulnya asam pada sambal sehingga produk ditolak oleh konsumen. Penelitian ini bertujuan untuk mengetahui pengaruh variasi cara kualitas sensoris, kimiawi, dan mikrobiologis sambal ikan pari asap kemasan jar kaca selama penyimpanan, umur simpan sambal, serta menentukan cara pemasakan untuk memperpanjang umur simpan sambal. Pengemasan menggunakan jar kaca dan variasi cara pemasakan pada sambal ikan pari asap dilakukan untuk mencegah penurunan mutu. Variasi cara pemasakan yang dilakukan yaitu pemasakan kering (P1), pemasakan setengah kering (P2), dan pemasakan kering dengan penambahan minyak setelah pemasakan (P3). Selanjutnya, untuk memenuhi standar keamanan pangan dan sebagai jaminan mutu dilakukan pendugaan umur simpan sambal ikan pari asap menggunakan metode ASLT model Arrhenius yang memiliki waktu pengujian relatif singkat dengan ketepatan dan akurasi tinggi. Parameter yang diuji adalah sensoris aroma, total asam tertitrasi (TAT), dan total plate count (TPC). Penurunan mutu sambal diamati pada penyimpanan suhu 35˚C, 45˚C dan 55˚C selama 48 jam dengan waktu pengamatan setiap 12 jam sekali. Berdasarkan hasil peneli tian, tiga variasi cara pemasakan sambal ikan pari asap memiliki penurunan mutu yang berbeda-beda selama penyimpanan. Umur simpan sambal ikan pari asap kemasan jar kaca menurut parameter kritis TAT pada cara pemasakan kering (P1) pada suhu 30˚C adalah 165,95 jam. Pada variasi pemasakan setengah kering (P2), umur simpan sambal pada suhu 30˚C adalah 155,04 jam. Pada variasi pemasakan kering dengan penambahan minyak (P3), umur simpan sambal pada suhu 30˚C adalah 197,96 jam. Variasi pemasakan kering dengan penambahan minyak goreng setelah pemasakan merupakan cara terbaik untuk memperpanjang umur simpan sambal ikan pari asap kemasan jar kaca.

Nutmeg oleoresin microcapsule is the solid, liquid, and gas coating technology of the nutmeg fruit. The purpose of this study was to know how mace nutmeg oleoresin microcapsules could preserve the broiler chicken meat at room temperature during 4 days of observation. The experimental design used was a Completely Randomized Design (CRD) consisting of 5 treatments with mace concentration of nutmeg microcapsules oleoresin (0, 50, 100, 150, and 200) ppm. The variables observed were water content, pH value, total microbes, and organoleptic properties (color, aroma, and texture). The results showed that mace nutmeg oleoresin microcapsules did not affect (p> 0.05) water content and sensory properties of broiler chicken meat, but had a significant effect (p <0.05) on the pH value and total microbe at the same day of room temperature storage. Panel organoleptic test results on the level of preference for meat color, aroma, and texture of chicken meat were in the range score of 3 (somewhat like) to 4 (somewhat dislike). The treatments of nutmeg oleoresin did not affect (p> 0.05) on color, the aroma, and the texture of broiler chicken meat. This research shows that marinating using oleoresin microcapsules has not been effective as a preservative to broiler chicken meat at room temperature.

Yogurt is a type of beverage classified as a refreshment drink which is produced through a fermentation process that uses Lactic Acid Bacteria. Most legumes have been widely used as raw materials in the making of a milk known as vegetable milk. Legume milk contains amino acids that are almost equivalent to the amino acid content of animal milk so it can be used as a base substitute material for fermented animal milk. Processed green bean milk yogurt is a form of food diversification. Skim milk is a low- fat milk added in the production of green bean milk yogurt, and yogurt starter is an important factor in the process of yogurt making. The purpose of the study is to determine the effects of the addition of yogurt starter and skim milk on the quality of green bean milk. The research design is 2-Factor Factorial Design arranged with Completely Randomized Design (CRD). Factor I consists of 2 levels, namely 12 grams of skim milk and 15 grams of skim milk; factor II consists of 3 levels, namely 15 ml, 20 ml, and 25 ml of starters. Observation variables consist of pH, total acid, viscosity, protein content, lactic acid bacteria, organoleptic aroma test, organoleptic texture test, and organoleptic taste test. From the results of this study, the highest results obtained in the treatment consist of: a) 12 grams of skim milk and 25 ml of 8.13%,Total Acid, Organoleptic Aroma Test 4.57, Organoleptic Texture Test 4.73; b) 15 grams of skim milk and 25 ml of starter of pH 4.17, Viscosity 8.67 cP, protein content 0.94%, Lactic Acid Bacteria 2933.33 x 103 CFU / mL, Organoleptic Aroma Test 4.57, Organoleptic Texture Test 4.61, Organoleptic Taste Test 5.02.
