Abstract

PEMANFAATAN BAKTERI PROBIOTIK INDIGENUS DALAM PEMBUATAN KEJU LUNAK[Utilization of Indigenous Probiotic Bacteria in the Production of Soft Cheese]Fifi Afiati1)*, Yopi1) dan Rarah R.A. Maheswari2)1) Pusat Penelitian Bioteknologi LIPI, Jl. Raya Bogor Km 46, Cibinong, Bogor2) Departemen Ilmu dan Teknologi Peternakan, Fakultas Peternakan, Institut Pertanian Bogor, Bogor Diterima 12 April 2013 / Disetujui 15 Februari 2014ABSTRACT Probiotic soft cheese containing lactic acid bacteria is one of functional food products. Three lactic acid bacteria namely Lactococcus lactis DSB 42 (LL-DSB42), Lactobacillus acidophilus RRM-01 (LA-RRM01) and Bifidobacterium longum RRM-01 (BL-RRM01) were used in the production of probiotic soft cheeses. Single culture (BL, LA, and LL) and mixed culture (BL-LA, BL-LL, LA-LL and BL-LA-LL) were used to produce diversified functional products. The preparation of probiotic soft cheese consists of pasteurization, addition of lactic acid bacterial culture (5%, v/v), addition of rennet, cutting the curd, scalding, draining and packaging. Soft cheese characteristics were analyzed physically (yield), chemically (pH, water content, crude protein, crude fat and ash) and microbiologically (lactic acid bacteria). The results showed that addition of lactic acid bacteria cultures significantly decreased the pH value (pH 5.10 to 5.79). The yield of probiotic soft cheese produced was in the range of 17.86-22.51% with water content of more than 55%. The fat and carbohydrate content of both cheeses of single and mixed cultures were significantly different (p<0.05) (fat content 5.1-7.4% for single culture and 4.0-9.3% for mix culture; carbohydrate content 11.6-17.7% for single culture and 4.6-12-2% for mix culture). The combination of all three starter cultures did not result in inhibition to each other, thus these combination were able to achieve the maximum number of 9.0 log10CFU g-1 on a single culture soft cheese and 9.8 log10CFU g-1 in mixed cultures soft cheese. In conclusion, soft cheeses with single culture (BL, LA, and LL) and mixed culture (BL-LA, BL-LL, LA-LL and BL-LA-LL) had excellent potential properties to be developed as probiotic foods.

Abstract

Sediaan bawang tunggal hitam terdiri atas bawang tunggal hitam utuh, ekstrak dan mikroenkapsulat. Senyawa antioksidan dalam sediaan bawang tunggal hitam akan mengalami kerusakan selama penyimpanan. Penelitian ini bertujuan menentukan kinetika degradasi kapasitas antioksidan dan total fenolik pada sediaan bawang tunggal hitam dan memperkirakan umum simpannya dengan metode accelerated shelf-life testing (ASLT). Hasil penelitian menunjukan kapasitas antioksidan dan total fenolik sediaan bawang tunggal hitam mengalami penurunan selama penyimpanan. Total fenolik dijadikan parameter penentuan umur simpan sediaan bawang tunggal hitam. Bawang tunggal hitam utuh mengalami kerusakan lebih cepat dibandingkan sediaan lainnya. Umur simpan sediaan bawang tunggal hitam pada suhu 25°C adalah: bawang tunggal hitam utuh 199 hari, ekstrak bawang tunggal hitam 259 hari, dan mikroenkapsulat 255 hari.ABSTRACTSolo black garlic products consisted of whole solo black garlic, extract, and microencapsulated. Antioxidant compounds in the black garlic products will be damaged during storage. The study was aimed to determine the kinetics degradation of antioxidant capacity and total phenolic of black garlic products and to estimate their shelf life using accelerated shelf life testing (ASLT) method. The result showed that antioxidants and total phenolic of products decreased during storage. Total phenolic was used to predict the shelf life of products. The whole black garlic deterioration is faster than other products. The shelf life of whole black garlic, black garlic extract and microencapsulated black garlic extract at 25°C were 199 days, 259 days, and 255 days respectively.
