Abstract

Prebiotik adalah komponen makanan yang tidak dapat dicerna di dalam tubuh dan mendorong pertumbuhan atau aktivitas mikroba usus yang bermanfaat seperti bakteri asam laktat (BAL). Namun, kemampuan Lactobacillus yang diisolasi untuk memanfaatkan prebiotik masih sedikit diketahui. Penelitian ini bertujuan untuk mengetahui pengaruh berbagai jenis prebiotik sebagai sumber karbon terhadap metabolisme isolat Lactobacillus indigenous dari teh kombucha, dadih (susu fermentasi tradisional) dan bambu yang digunakan untuk wadah dadih. Kemampuan isolat Lactobacillus dalam memetabolisme berbagai prebiotik sebagai sumber karbon dilakukan dengan menumbuhkan BAL dalam media MRSB dimana kandungan glukosa diganti dengan prebiotik yaitu fruktooligosakarida (FOS), galaktooligosakarida (GOS) dan inulin, kemudian penurunan kadar glukosa diukur setelah inkubasi 24 jam. Pengukuran total glukosa dilakukan dengan metode fenol sulfat. Hasil penelitian menunjukkan keseluruhan isolat Lactobacillus mengalami peningkatan jumlah sel selama inkubasi 24 jam yaitu dari 0,52 menjadi 1,26 log. Penurunan kadar glukosa berkisar antara 3,80 ± 0,44% sampai 91,33 ± 4,83%. Penurunan kadar glukosa tertinggi terjadi pada isolat L. plantarum1 RB210 yaitu 91,33 ± 4,83% dan tidak berbeda nyata (P>0,05) dengan L. paracasei RK41 dan L. paracasei RL2 yang ditumbuhkan pada media inulin. L. plantarum1 MK2 menunjukkan penurunan pH tertinggi yaitu 1,91 ± 0,08 dan tidak berbeda nyata (P>0,05) dengan L. rhamnosus MY2 pada media yang mengandung GOS. Hasil penelitian ini menunjukkan bahwa isolat Lactobacillus Indigenus secara definitif dapat menggunakan prebiotik sebagai sumber karbon untuk metabolismenya. Hasil penelitian ini memberikan dasar pengaruh penggunaan probiotik dan prebiotik untuk aplikasi sinbiotik sehingga dapat memodulasi mikrobiota usus.

Abstract

The purpose of this study was to identify the species of Lactobacillus which has the potency as superior probiotic based on their ability to ferment sugars. The study was conducted in two steps, the first was a confirmation test of the five lactic acid bacteria (LAB) isolates of breast milk A1, A6, A8, B8, and B10b. All of the LAB isolates were Gram positive rod and negative catalase. This shows that all of the isolates were of the genus of lactic acid bacteria and readily for the second step testing. The second step was to determine the LAB isolates ability to ferment 50 sugars (carbohydrates) using API 50 CHL kit. Results from the API 50 CHL kit test showed that the 5 LAB isolates were of indigenous LAB with the identification level of 88,7% - 99,9%. The species found were three spesies of Lactobacillus plantarum-1 (Lactobacillus plantarum-1 A1, Lactobacillus plantarum-1 A8, Lactobacillus plantarum-1 B8),and 2 spesies of Lactobacillus rhamnosus (Lactobacillus rhamnosus A6, and Lactobacillus rhamnosus B10b), respectively.

Abstract

Fermented milk is milk that is fermented by lactic acid bacteria. Fermented milk containing live lactic acid bacteria is very good for the health of the digestive system. One example of a very well-known fermented milk product is dadih. Dadih is a traditional Minangkabau yogurt made from buffalo milk. Dadih is made traditionally and there is no standard manufacturing process, so the quality of dadih varies in terms of taste, aroma and texture. Traditional production of dadih without starter causes the consistency of taste, aroma and texture to be difficult to maintain. The controlled fermentation process in the manufacture of dadih uses probiotic bacteria so that it has the opportunity to be developed as a functional food. The purpose of this study was to determine the potential of Indigenous Lactobacillus isolated from bamboo as a starter culture in the development of dadih as a functional food. Lactobacillus isolates used in this study were isolates ML7, MR2, RL2, RL4, RM1 and RN9. The results showed that the use of various types of Lactobacillus isolates had a very significant effect (P>0.01) on yield, moisture content, ash content, protein content, pH, total acid, total LAB and sensory evaluation of the dadih produced. The use of Lactobacillus RN9 isolate as a starter culture produced the best dadih with yield characteristics of 78.33%, moisture content 78.94%, ash content 1.09%, protein content 6.74%, pH 4.75, total titrated acid 0.56 %, total LAB 8.70 log CFU/g and yellowish white color typical of milk, slightly sour milk aroma, savory like cheese aroma, sour milk taste and no bitter aftertaste, soft to slightly hard texture, soft and compact or not sandy.

Abstract

Nugget production requires a filler. The filler most often used in chicken nugget production is wheat flour. Wheat flour is an imported foodstuff, so domestic demand for wheat flour depends on wheat flour- producing countries. On the other hand, there are several types of local flour in Indonesia that can be used to replace wheat flour, notably Talas Beneng flour. The purpose of this study is to determine the impact of replacing wheat flour with Talas Beneng flour on the characteristics of chicken nuggets, and to create the best possible chicken nuggets. A completely randomized design was employed in this study, with the treatment of wheat flour replacement by Talas Beneng flour comprising 6 levels of treatment, namely: 100%:0%; 80%:20%; 60%:40%; 40%:60%; 20%:80%; 0%:100%. Parameters observed were crude fiber content, protein content, water content, water holding capacity, cooking loss, hardness and sensory analysis, including color, aroma, texture, taste and overall acceptability. The data obtained were tested using analysis of variance (? = 0.05) and, where a significantt effect was observed, it was followed up using Duncan's multiscale test (? = 0.05). The results showed that replacing wheat flour with Talas Beneng flour had a significant effect on water content, protein content, crude fiber content, water-holding capacity, loss on cooking, hardness, color, texture, taste and overall acceptability, but no significant effect on the taste of chicken nuggets. The best nuggets were obtained when treated with a 40% substitution of Talas-Beneng flour, with the following characteristics: crude fiber content 6.10%; protein content 28.37%; water content 49.93%; water retention 17.75%; cooking loss 10.77%; hardness 5.09 N; color is like, aroma, texture, taste and general acceptability are slightly like.
