Abstract

Kecap merupakan produk cair yang diperoleh dari hasil fermentasi dan atau cara kimia dengan atau penambahan bahan makanan lain dan bahan tambahan yang diizinkan. Potensi ampas tahu di Indonesia cukup tinggi. Menurut data BPS pada tahun 2013 jumlah ampas tahu adalah sebanyak 731.501 ton/tahun. Pemanfaatan ampas tahu menjadi kecap dilakukan karena ketersediaannya yang cukup terjamin dan ampas tahu masih mengandung protein sekitar 5 %. Tujuan dari penelitian ini adalah mengetahui pengaruh lama fermentasi (4,5,6 dan 7 minggu) kecap ampas tahu terhadap kualitas fisik, kimia dan organoleptik.Hasil penelitian menunjukkan bahwa lama waktu fermentasi berpengaruh terhadap kualitas fisik, kimia dan organoleptik. Kecap manis perlakuan terbaik memiliki kadar protein 6.83% (termasuk dalam mutu I), total gula 41.64%, total mikroba 1.5x101 cfu/ml, pH 5, Total padatan terlarut 48.80% serta viskositas 70.49 dP.   Kata kunci: Ampas Tahu, Kecap, Waktu Fermentasi

Abstract

Sosis merupakan produk olahan daging yang memiliki nilai gizi yang tinggi. Untuk itu diperlukan bahan baku dengan harga yang terjangkau dengan kandungan protein yang tinggi. Sehingga pada penelitian ini menggunakan ikan lele sebagai bahan baku sosis. Ikan lele (Clarias gariopinus) merupakan salah satu komoditas perikanan yang memiliki kandungan protein sebesar 63.86%, mudah dicerna dan mempunyai kandungan asam amino esensial yang lengkap dan seimbang. Untuk meningkatkan kandungan gizi pada sosis, proses pengolahannya dilakukan dengan cara fermentasi. Proses fermentasi ini ditambahkan bakteri Lactobacillus plantarum yang merupakan bakteri homofermentatif dan tahan dalam kondisi asam. Perlakuan terbaik diperoleh pada lama pengasapan 60 menit dan lama fermentasi 2 hari dengan karakteristik kadar pH 5.27, total asam 7.730%, total BAL 1.19 x 109 cfu/ml, protein 17.49%, lemak 10.39%, kadar air 57.24%, kadar abu 2.37%, organoleptik rasa 2.57 (suka), aroma 2.60 (suka), warna 2.57 (suka) dan tekstur 2.57 (suka).   Kata Kunci: Fermentasi, Ikan Lele, Lactobacillus plantarum, Sosis

Abstract

Iradiasi merupakan teknologi non termal yang dapat mereduksi bakteri pembusuk dan pathogen pada bahan pangan seperti Eschericia coli, Salmonella, Staphylococcus aureus, Coliform dan Camphylobacter  jejuni pada daging ayam. Efektifitas iradiasi gamma dalam mereduksi bakteri dipengaruhi beberapa factor yaitu jenis bakteri, dosis iradiasi serta kondisi sebelum dan setelah iradiasi. Selain efektifitasnya dalam membunuh bakteri pathogen dan pembusuk teknologi iradiasi gamma dapat menjaga nutrisi, tekstur dan warna yang biasa ditimbulkan oleh pengawetan pangan konvensional (menggunakan panas).   Kata kunci: Bakteri Patogen, Daging Ayam, Iradiasi, Pasar Modern, Pasar Tradisional

Abstract

Button mushroom (Agaricus bisporus) is an edible mushroom that has nutritional value and bioactive compounds like β -glukan, unsaturated fatty acids, tocopherol, ergosterol, lectins, polyphenol vitamin D, and selenium  that are beneficial for health. The limiting factor of this commodity is its short shelf life, which is 3-4 days after harvest. This research aims to determine the optimum concentration of anti-browning agents (citric acid and EDTA) in the pretreatment process of fresh button mushrooms to obtain the best physical properties (water content, browning index/BI, texture, and weight reduction).  The research design uses  Response Surface Methodology with Central Composite Design through Design Expert 12 software with a combination of treatment factors are the concentration of citric acid (%) and EDTA (ppm). The results showed that the optimum concentration of citric acid and EDTA was 0.5 % and 100 ppm with the results are 93.63 % for water content, 28.89 % for BI, 23.061 N for texture, and 4.34 % for weight change.  This condition is classified as still suitable for consumption.

Abstract

Water kefir is a fermented drink made by adding water kefir grains to a water solution containing dried fruit or sugar. This research aims to determine the effect of sucrose, starter, and interactions on the chemical characteristics (antioxidant activity, total acid, medium pH) and organoleptics of fig leaf tea water kefir and to determine the interaction of antioxidant activity with total acid and medium pH. The experiment used variations in starter concentration (5% and 8%) and sucrose concentration (3%, 6%, 9% and 12%). Water kefir was analyzed through chemical analysis (antioxidants, total acid, medium pH, and sugar content) and organoleptic tests (flavor, aroma, color, and overall preference). The results showed that variations in the addition of sucrose, starter, and interactions influenced the metabolic results (primary and secondary metabolites) of microorganisms in water kefir grains and statically had a significant effect on changes in chemical and organoleptic properties (flavor, aroma, and overall preference). The best chemical characteristic parameters were obtained in the B2S3 treatment (8% starter + 9% sucrose) with antioxidant activity of 51.27%, total acid of 0.70%, and medium pH of 3.53. Meanwhile, the best organoleptic parameters were obtained in the B2S4 treatment (8% starter + 12% sucrose) with a taste value of 5.56 (liked), an aroma value of 4.80 (slightly liked), a color value of 4.97 (slightly liked), and the overall liking level was 5.45 (liked), and the antioxidant activity of fig leaf tea water kefir had a strong relationship with total acid and medium pH. Furthermore, the addition of sucrose and different starters during the water kefir fermentation process affects the chemical and organoleptic properties of fig leaf tea water kefir. It is hoped that the results of this research will make fig leaf tea water kefir an alternative probiotic drink for sufferers of lactose intolerance and allergies to milk-based drinks.
