Abstract

Kulit buah manggis (KBM) merupakan bagian terbesar dari buah manggis (Garcinia mangostana L.) yang dikategorikan sebagai limbah. KBM mengandung berbagai senyawa antioksidan, terutama xanthone, antosianin dan fenolik. Ekstraksi antioksidan KBM banyak dilakukan dengan pelarut kimia non-foodgrade, sedangkan dengan pelarut yang foodgrade yang masuk dalam kelompok GRAS (Generally Recognized as safe) belum banyak dilakukan. Tujuan dari penelitian ini adalah untuk mengetahui kadar dan kapasitas antioksidan yang mampu diekstrak dari tepung KBM oleh pelarut air, etanol 70%, etanol 96%, aseton 72% dan aseton 90% dengan metode maserasi. Hasil penelitian menunjukkan bahwa tepung KBM yang digunakan mengandung kadar air 5,87%, abu 2,17%, lemak 6,45%, protein 3,02%, total gula 2,10% dan karbohidrat by different 82,50%. Kadar xanthone tertinggi ekstrak tepung KBM terdapat pada pelarut aseton 90% sebesar 78,52 mg/g tepung KBM. Kadar antosianin dan fenolik tertinggi terkandung pada ekstrak pelarut air masing-masing sebesar 6,22 mg/g tepung KBM dan 154,57 mg/g tepung KBM. Analisa DPPH (1,1-diphenyl-2-piercrylhydrazil) menunjukkan bahwa pelarut aseton 72% dan etanol 70% memiliki kapasitas antioksidan yang tinggi yaitu masing-masing 89,31 % dan 86,63%. Rata-rata kapasitas antioksidan pada seluruh perlakuan pelarut lebih tinggi 8,75% dari kapasitas antioksidan standar pembanding vitamin C (asam askorbat) 800 ppm. Jenis pelarut foodgrade (air dan etanol) memiliki potensi yang baik untuk digunakan dalam mengekstrak antioksidan pada tepung KBM dan pelarut yang optimum menghasilkan antioksidan adalah pelarut etanol 70%. Concentration and Antioxidant Capacities of Mangosteen Pericarp Extracts in Various Solvents with Maceration MethodMangosteen pericarp (KBM) is the largest part of the mangosteen fruit (Garcinia mangostana L.) which were categorized as waste. KBM containing various antioxidant compounds, especially xanthones, anthocyanins and phenolics compound. KBM antioxidant extraction is mostly done by non-foodgrade chemical solvents, whereas with the incoming solvent foodgrade (Generally Recognized as Safe) has been not done a lot. The aim of this study was to determine levels and antioxidant of capacity that could be extracted from the KBM powder by various solvents (water, ethanol 70%, ethanol 96%, acetone 72% and acetone 90%) with the maceration method. The results showed that the KBM powder used containing of 5.87% of moisture contents, ash 2.17%, fat 6.45%, protein 3.02%, total sugars 2.10% and carbohydrate (by different) 82.50%. Highest levels xanthone found in extracts of KBM powder was in acetone 90% solvent about 78.52 mg/g KBM powder. The highest levels of anthocyanin and phenolic contained in water solvent extracts about 6.22 mg/g KBM powder and 154.57 mg/g KBM powder, respectively. In addition, DPPH analysis showed that acetone 72% and ethanol 70% have high antioxidant capacities of the respective 89.31 % and 86.63%. Antioxidant capacities average in all solvents treatment were higher 8.75% than the Vitamin C (ascorbic acid) 800 ppm. The foodgrade solvents (water and ethanol) have a good potential for extracting antioxidant compouds, and ethanol 70% is the best solvent to produce extract of KBM flour which have good concentration and antioxidant capacity level.

Abstract

Campylobacter spp. is a bacteria foodborne zoonotic agent that can infect humans and animals, especially birds. This bacteria can cause important problems in the public health since the beginning at the farm level, the level of retail and on the table. Poultry meat is the main source of contamination because the digestive tract of poultry is the predilection of Campylobacter jejuni. During this infection C. jejuni in poultry did not show typical clinical symptoms, making detection quite difficult to diagnose this disease at the farm level. Incidence infection of Campylobacter sp. in developed countries had 5-90%. Currently poultry production and consumption are predicted to still increase due to a high demand for low price protein. This research is conducted to determine the clinical and pathologic anatomy due to an infection of C. jejuni on chicken digestive tract. A total of 105-day-old chickens are divided into 3 groups, each consisting of 35 individuals. Group A was the control group (not infected) group B (infected with C. jejuni ATCC 33291), and group C (infected with field isolate of C. jejuni/C1). Infection of the chicken is done 0.5 ml peroral suspension concentration of104cfu/ml. Anova Duncan is used to analyze parameters of body weight, increase weight gain, feed consumption, FCR values. Kurskall Walis method used to analyze the parameters non-parametric form of the score changes in the macroscopic and microscopic intestinal and liver. Infection of C. jejuni changes the pathology anatomy of intestine i.e. hyperemia, enteritis and enteritis catharalis haemorrhagic. A microscopic change of intestinal is oedema,haemorrhage and infiltration of inflammatory cell. Changes of pathology anatomy liver are colour smeary, congesti, pale, fragile and necrotic. Microscopic changes of liver are degeneration and focal hepatic necrosis. Group observation infected by C. jejuni caused chicken cannot reach maximum body weight and can be detrimental to farmers because of increase of the value of the feed conversion ratio (FCR).

Abstract

Sufu is a traditional Chinese fermented soybean curd (tofu) resembling a soft creamy cheese-type product. It is made by fungal solid-state fermentation of tofu followed by aging in saturated brine solution. The aims of the research were to obtain the best indigenous mold strain for sufu fermentation and to produce the low salt sufu by applying Lactobacillus plantarum kik during aging. Four indigenous mold strains were used i.e Rhizopus oligosporus, R. oryzae, Mucor hiemalis and Actinomucor elegans. To produce the low salt sufu, the salt concentrations applied were varied in the range of 6% - 12% and by combination of 3% (v/v) L. plantarum kik. The results showed that the fermentation time of pizi was influenced by the mold species. Further sensory evaluation (Balance Incomplete Block Rating Design) on the hedonic rating of sufu revealed that aging in 9% brine and application of 3% (v/v) L. plantarum kik produced the most preferred sufu by the panelists. Combination of L. plantarum kik and pasteurization of sufu could maintain the quality for three weeks. Keywords: pizi, sufu, fungal, Lactobacillus plantarum kik

Abstract

Individually implementation of management system standard of quality (ISO 9001), food safety (FSSC 22000), and halal assurance (HAS 23000) require a lot of resources in a food company. This study aimed to develop perangkat of internal audit (IA) by integrating the three standards into an Integrated Management System (IMS) based on the management system requirements framework, PAS 99:2012. The study was started by integrating all the major requirements of standards follows the Deming's PDCA cycle approach consisting of 7 clauses. The perangkat of IA was developed based on the IMS and implemented in PT IBP. Evaluation the effectiveness of the perangkat of IMS IA is done by analyzing the gap of IA results with external audit results. For integration of the standards, the most standard used as a case of IMS was the standard of FSSC 22000. The result of IA using the developed perangkat of IA was in agreement with the result of external audit. This suggest that the integration of the audit system has adequately covered all requirements based on the 3 standards. In addition, there is an opportunity to improve the ability of internal auditors in assessing the conformity of the implementation of planning.

Abstract

Good practices in food chain are very important to ensure product quality and safety. Good practices start from raw material usage, manufacturing, warehousing, distribution, retailing, until product consumption by consumers. Milk powder is a high value commodity but it is a high risk product. Good warehousing and distribution system must be in place to ensure product quality and safety. Quality and food safety system evaluation model consists of 4 steps: plan, do, check, and action. A model on quantitative evaluation system for good warehouse practice (GWP) and good distribution practice (GDP) consist of five points (internal, external area, transportation, quality management, and inventory management). These five points were detailed to 30 sub points. Criteria and requirements have been included for each sub point, and defined by 5 scales (0, 1, 2, 3, and 4). Furthermore, the evaluation system has been implemented at 3 distributors (A, B, and C) in 30 cities. The result showed that distri- butors A, B and C complied to the criteria with the score of 77.32+4.05%, 84.17+5.80%, and 73.30+ 6.64%, respectively. The distributors were categorized as very good (13.30%), good (60.0%) and fair (13.30%).

Abstract

Saluran pencernaan (terutama usus) ikan perairan estuaria merupakan salah satu ceruk lingkungan potensial Actinobacteria yang belum tereksplorasi. Penelitian ini bertujuan untuk mengisolasi dan mengidentifikasi karakteristik morfologi Actinobacteria asal ikan bandeng (Chanos chanos) dan belanak (Mugil cephalus) serta mengevaluasi aktivitas antimikroba yang dihasilkannya. Penelitian ini diawali dengan mengambil usus ikan, kemudian digesta usus secara perlahan dipisahkan untuk dieksplorasi keberadaan Actinobacteria dengan menggunakan media isolasi selektif. Isolat yang diperoleh dikarakterisasi berdasarkan ciri makroskopik dan mikroskopik, serta dilakukan penapisan antibakteri awal menggunakan metode double-layer diffusion. Isolat dengan zona penghambatan terbaik dipilih untuk dilakukan produksi dan ekstraksi senyawa antibakteri, serta uji aktivitas antibakteri dengan metode difusi cakram terhadap bakteri uji Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa dan Escherichia coli. Sebanyak 44 isolat Actinobacteria telah diisolasi dari digesta usus ikan bandeng (Chanos chanos) dan belanak (Mugil cephalus) menggunakan media strach casein dan actinomycete isolation agar. Sebagian besar isolat yang diperoleh menunjukkan karakteristik morfologi genus Streptomyces sp., seperti koloni memiliki tekstur menyerupai serbuk, bertepung dan kasar, memiliki aerial miselium berwarna putih dan substrat miselium berwarna krim susu, serta memiliki bentuk rantai spora rectus-flexibilis. Proses penapisan antibakteri isolat Actinobacteria menunjukkan 22 isolat memiliki indeks penghambatan terhadap sedikitnya satu bakteri uji, dengan aktivitas terbaik ditunjukkan oleh isolat A-SCA-11. Uji antibakteri terhadap ekstrak kasar isolat A-SCA-11 menunjukkan aktivitas antibakteri berspektrum luas yang mampu menghambat seluruh bakteri uji dengan zona hambat tertinggi pada P. aeruginosa.  AbstractThe gut of estuary fish is one of the potential novel niches of Actinobacteria that has not yet been explored. This study aimed to isolate and identify the morphological characteristics of Actinobacteria from milkfish (Chanos chanos) and blue-spot mullet fish (Mugil cephalus) and to evaluate the antibacterial activity produced. This research was started by taking the fish gut, and then the digesta were slowly separated to explore the presence of Actinobacteria using selective isolation media. The isolates obtained were characterized by macroscopic and microscopic characteristics, and antibacterial preliminary screening of isolates was performed using a double-layer diffusion method. The isolates with the best inhibition zone were selected for production and extraction of antibacterial compounds, and antibacterial activity tests using the disk-diffusion method against the test bacteria Staphylococcus aureus, Bacillus cereus, Pseudomonas aeruginosa, and Escherichia coli. A total of 44 isolates of Actinobacteria have been isolated from the gut of fish using starch casein and actinomycete isolation agar. Most isolates showed morphological characteristics of the genus Streptomyces sp., such as colonies with a tough or powdery texture, antibacterial have white aerial mycelium and milk-cream substrate mycelium, and rectus-flexibilis spore chain. The antibacterial preliminary screening of Actinobacteria isolates showed 22 isolates had inhibitory index against at least one test bacterium, with the best activity indicated by A-SCA-11. Antibacterial test of A-SCA-11 crude extract showed broad-spectrum antibacterial activity that was able to inhibit all test bacteria with the highest inhibitory zone on P. aeruginosa.

Abstract

Susyi adalah pangan siap konsumsi asal Jepang, merupakan kombinasi nasi yang diberi asam dan ikan mentah. Umumnya susyi terdiri dari beberapa jenis, namun terdapat dua jenis susyi yang sangat dikenal yaitu nigiri (nasi dengan ikan mentah di atasnya) dan maki (nasi dengan ikan mentah di dalamnya). Ikan dalam susyi tidak mengalami pemanasan sehingga rentan terhadap kontaminasi patogen, di antaranya Staphylococcus aureus dan Bacillus cereus. Kedua bakteri ini telah dilaporkan sebagai penyebab Kejadian Luar Biasa (KLB) di Indonesia, namun keberadaannya di dalam susyi belum pernah dilaporkan. Penelitian bertujuan untuk menentukan prevalensi dan tingkat kontaminasi S. aureus dan B. cereus pada susyi di tingkat ritel di wilayah Jabodetabek (Jakarta, Bogor, Depok, Tangerang, dan Bekasi). Sebanyak 120 sampel terdiri dari nigiri (n=57) dan maki (n=63) diperoleh dari ritel di Jabodetabek. Identifikasi dilakukan dengan metode Polymerase Chain Reaction (PCR), dengan target gen nuc (S. aureus) dan gyrB (B. cereus). Jumlah bakteri menggunakan metode lempeng sebar (spread plate) untuk S. aureus dan Angka Paling Mungkin (APM) untuk B. cereus. Prevalensi S. aureus (7,5%) di dalam susyi lebih besar dibandingkan B. cereus (5%). Tingkat kontaminasi S. aureus (8,9x102-1,5x105 koloni/g) juga lebih tinggi dibandingkan B. cereus (9,2-93 APM/g). S. aureus lebih sering ditemukan dalam maki (9,5%), sementara B. cereus lebih banyak ditemukan pada nigiri (7,1%). Susyi dengan ikan salmon memiliki prevalensi S. aureus (9,3%) dan B. cereus (5,3%) lebih tinggi dibandingkan dengan tuna. Kontaminasi S. aureus kemungkinan karena kurang terpenuhinya higiene personal, sementara B. cereus dapat berasal dari penanganan nasi yang kurang baik dan sanitasi lingkungan yang kurang memadai. Keberadaan S. aureus di dalam susyi lebih berpotensi menyebabkan risiko keracunan pangan dibandingkan B. cereus. Program higiene personal dalam produksi susyi harus ditingkatkan untuk memberi jaminan keamanan.
