Abstract

The Lactic Acid Bacteria with Milk Clotting Activity (MCA) were isolated from Bakasam, an Indonesian traditional fermented meat. The isolate screening was carried out using modified method of Skim Milk Agar and Milk Clotting Activity Test, and the isolate was then identified using 16S rRNA. We found 4 isolates that showed MCA of 18-20 SU/ml. Identification using 16S rRNA indicated that the isolate ALG.1.15 was 99% (FR3-F primer) and 99% (FR3-R primer) identic with Enterococcus faecium. The isolate potentially produced renin-like protease to subtitute renin from veal.

Abstract

Recently, the popularity of coffee is gaining popularity. The researcher found that the benefit of coffee was not refreshing only but also improved the quality of health. These effectsexistdue to the natural bioactive compounds found in the coffee. The bioactive compounds of coffee have activity as an antioxidant, anti-inflammation, anti-microbe, and recently as antidiabetic. The major compounds found in coffee were chlorogenic acid, trigonelline, diterpene, and Maillard reaction product (exp.melanoidin). The objective of this study was to explore the bioactive compounds of coffee and the potency antidiabetic, conducted by in-vitro, in-vivo, clinically, and epidemiology intergrately. The in-vitro analysis shown thatcoffee had activity asan inhibitor a-glucosidase, the compounds were chlorogenic acids. In the in-vivo study,coffee brewwas able to reduce blood glucose concentration of a rat model of type-2 diabetes by increasing insulin sensitivity. Caffeine and chlorogenic acids probably had an antagonist effect on glucose response. At the early stage of a clinical study, blood glucose concentration tend too increasedacutely and gradually reduces along with insulin sensitivity higher. A chlorogenic acid had a potency to decrease blood glucose concentration byseveral mechanisms such as -glucosidase inhibitory and raise insulin sensitivity. Furthermore, epidemiology studied shown that the efficacy of coffee consumption in the long-termwas able to reduce the risk of diabetes type 2. The effectiveness of coffee as antidiabetic depends on some factors such as gender and variation of coffee such asvariety, brewing technique, and frequency consumption of coffee.ABSTRAK Konsumen kopi saat ini makin meningkat, kepopulerannya ditandai dengan industri hilir kopi yang merebak di tengah-tengah masyarakat. Konsumsi kopi selain memberikan efek menyegarkan juga memiliki manfaat dalam meningkatkan taraf  kesehatan konsumennya. Komponen bioaktif pada kopi memiliki aktivitas seperti antioksidan, antiinflamasi, antimikroba dan antidiabetes. Kandungan biokatif kopi yang berperan dalam aktivitas tersebut adalah asam klorogenat, trigonelin, diterpen dan produk reaksi Maillard (cth.melanoidin). Tujuan dari tulisan ini adalah menggali senyawa bioaktif yang terdapat pada kopi dan potensinya sebagai antidiabetes secara terpadu baik secara in-vitro, in-vivo, klinis dan epidemiologi. Berdasarkan penelitian secarain–vitrobahwa komponen bioaktif kopi yang berperan dalam menghambat aktivitas a-glukosidase adalah asam klorogenat. Secara in-vivobahwa seduhan kopi yang dikonsumsi oleh tikus penderita diabetes menghasilkan kadar glukosa darah yang menurun karena peningkatan sensitivitas insulin. Efek kafein kemungkinanberlawanan dengan asam klorogenat terhadap glukosa darah. Pada awal pengujian secara klinis kadar glukosa darah akan meningkat secara akut dan kemudian menurun seiring meningkatnya efek asam klorogenat. Asam klorogenat akan berperan dalam menghambat transportasi glukosa dan meningkatkan sensitivitas insulin. Penelitian secara epidemiologi menunjukkan bahwa konsumsi kopi dalam jangka waktu yang lebih lama dapat menurunkan resiko penyakit diabetes mellitus tipe 2. Persentase penurunan penyakit diabetes melitus dipengaruhi oleh faktor gender dan variasi kopi seperti jenis, teknik menyeduh dan frekuensi konsumsi kopi.

PENGARUH MINUMAN BEROKSIGEN TERHADAP  SISTEM IMUN, KADAR MALONALDEHIDA DAN PERFORMA RESPONDEN MAHASISWA OLAHRAGAWAN[Effect of Oxygenated Water on Immune System, Malonaldehyde Content and Student-Athlete Performance]Cesar Welya Refdi, Fransiska Rungkat Zakaria* dan Puspo Edi GiriwonoDepartemen Ilmu dan Teknologi Pangan, Fakultas Teknologi Pertanian, Institut Pertanian Bogor, Bogor Diterima 23 Agustus 2013 / Disetujui 01 Juli 2014ABSTRACT   Exercise requires more oxygen input and cannot be fully obtained through breathing. The body has a homeostatic system, when more ATP is needed, the more oxygen is required by the body. Limited supply of oxygen such as those happens in athlete’s body automatically switches the respiration from aerobic into anaerobic. This situation results in building up of lactic acid which in turn lowers the energy for cellular metabolism as well asenergy for exercise. The purpose of this study was to assess the effects of short-term and long-term drinking of oxygenated water on lactic acid and energy expenditure (EE) in exercise performance; Cluster of Differentiation-4 (CD4), CD8, CD56, Interleukin-6 (IL-6) contents; and level of malonaldehyde. During short-term intervention, 12 male student volunteers drank oxygenated (50, 80 and 130 ppm) water and normal mineral water, 15 minutes before treadmill and after treadmill (10 Kmh). The lactic acid concentration was measured before and after treadmill, and 5 minutes after the reconsumption of the oxygenated water. During long-term intervention, 17 male student volunteers drank oxygenated (100 ppm) water twice a day for 21 days. The blood plasma and lymphocyte sampled before and after intervention were analyzed for the same parameters. The results showed that oxygenated water had no effect on lactic acid accumulations and EE. Similarlyt he long-term study showed that oxygenated water did not affect CD4 and CD8, had no harmful effect on IL-6 and malonaldehyde, yet it significantly increased the CD56 content.

Abstract

Information about heat resistance (D and z values) of target bacteria is needed for the thermal process design on drink from Green Grass Jelly (Premna oblongifolia Merr.) and Roselle (Hibiscus sabdariffa L.), so it can guarantee quality and safety of the product. The objectives of this research were to isolate Staphylococcus aureus from commercial green grass jelly and to determine the D and z values of Staphylococcus aureus (from commercial product and standard clinical isolate ATCC 25923) on heating menstruum of green grass jelly and roselle. Isolation of S. aureus was done by inoculation in selective medium, D and z values of Staphylococcus aureus were assessed by heating at constant temperatures of 57, 53, 49, and 45°C during the time interval 2.5, 5, 10, and 15 minutes. The results showed that one isolate (Isolate A) gave positive response of Staphylococcus aureus in isolation tests and had similar percentage with the reference culture of 41.8% using the API Staph Kit. Heat resistance of Staphylococcus aureus (represented as D value) isolated from green grass jelly at constant heating temperature of D45, D49, D53 and D57 were 32.3, 17.9, 4.6, and 1.5 minutes. On the other hand, D value of isolates ATCC 25923 (standard clinical isolate) at constant heating temperature of D45, D49, D53 and D57 were 18.5, 6.8, 2.9, and 1.4 minutes. The z value of isolates A and ATCC 25923 were 8.8°C and 10.8°C. Smaller z value of isolate A showed that pasteurization process can be accelerated and optimized with increasing the temperature slightly but has the same lethality effect.

Abstract

Lactic acid bacteria (LAB) are one of Indonesia's biodiversity which can be beneficial for food and health purposes. Some of LAB are potential probiotics with specific functional properties, such as antidiabetes. This study evaluated the effect of ethanol extracts of twelve indigenous LAB in inhibiting α-glucosidase enzyme and their antioxidant activities. Assay for the α-glucosidase inhibition was performed on LAB ethanol extract using spectrophotometric method at λ=410 nm, while the antioxidant activity was measured using 1,1-diphenyl-2-picrylhydrazyl (DPPH) method at λ=517 nm. The results showed that α-glucosidase inhibition was significantly different between the isolates (P<0.01). Lactobacillus fermentum S21209 had the highest α-glucosidase inhibition activity, which was significantly different from Lactobacillus plantarum MB427, Lactobacillus plantarum Pi28a, Lactobacillus delbrueckii W24802 and Lactobacillus plantarum 2 W22409. Evaluation of the antioxidant activity also showed significant difference between the isolates (P<0.01). Lactobacillus plantarum BSL had the highest antioxidant activity (92.81±1.36%), which was not significantly different from vitamin C as a control. This preliminary study reported that twelve indigenous LAB could be used as potential antidiabetic probiotics, although the responsible compounds are not known.

Abstract

Food allergy is a hypersensitive response to food, generally protein, triggered by body immune system. These responses can be mild, however in very rare cases may cause severe reactions and life threatening known as called anaphylaxis. Food allergy has been one of the main factors for product recall. It can happen due to many reasons, such as product package labeling fault, raw material labeling fault and cross contamination. Validation of the effectiveness of cleaning and sanitation process become a critical point to minimize cross contamination. This study aimed to determine the optimum chemical concentration and contact time to eliminate egg residue in biscuit production cleaning process, obtain valid and verified cleaning procedures, and produce cleaning procedures that can be implemented in a production line. The result showed that physical cleaning/pre-cleaning for 30 minute and using 1% (v/v) concentration of caustic based polybrite chemical cleaning for 3-minute contact time can effectively eliminate the egg residue on stainless steel and polyurethane surface equipment. Food contact surface material and product characteristics (wet dough, dry biscuit) affected the number of egg residue on the equipment. Packing area with food contact surface equipment made from stainless steel is not considered critical area for allergen sanitation. It is shown that prior to sanitation process, analysis of egg allergen residue has already given negative result. Validation process can prove the effectiveness of allergen sanitation process to prevent potential egg allergen cross contamination in biscuit production.

Abstract

In Indonesia, determination of glycemic index (GI) was performed according to approved protocols prescribed by FAO (1998) and BPOM (2011); but, remarkable differences among these methods exist, primarily regarding the points of recommendation. This present work aimed to evaluate the technical steps of the protocol for determining GI between two protocols recommended by BPOM (2011) and FAO (1998). Ten healthy subjects (age 21-36 years old and body mass index (BMI) 18.5-24.9 kg/m2) were recruited for the study. The blood glucose was measured with repeated glucose trials, while the number of sampling points for the blood glucose test was also investigated. The range of GI for rice, wheat cookies, NS-cookies, HMT-cookies were 68 – 77; 55 – 60; 35 – 43; 35 – 41, respectively, using the combination of three different aspects between FAO and BPOM protocol. Noticeably, the difference in glucose trials did not cause significant variations to GI (n=10, p>0.05). Regarding statistical performance between methods, the Coefficient of Variance (CV) resulted from BPOM protocol (10 subjects, 5 sampling points) ranged 37 to 49%, being slightly higher compared to CV obtained from FAO protocol (7 subjects with triplicate glucose trials, 7 sampling points), i.e., 33% and 35%. The conclusive remark was noticed, that the most satisfying protocol for determination of GI was achieved using no less than two reference food trials, seven subjects, and seven blood sampling points.
