Lada putih bubuk mempunyai sifat sangat higroskopis, sehingga mudah mengalami kerusakan, baik fisik, kimia ataupun mikrobiologis. Tujuan dari penelitian adalah menentukan mutu lada putih bubuk, baik secara fisik, kimia dan mikrobiologi dari pasar tradisional dan modern di wilayah Bogor dan Jakarta serta mendapatkan informasi awal/indikasi adanya pencampuran bahan lain pada lada putih bubuk. Metodologi penelitian terdiri atas beberapa tahapan, yaitu metode pengambilan sampel dilakukan secara acak sederhana (simple random sampling), dari pasar tradisional yang dijual secara curah, dan pasar modern yang dikemas dalam botol plastik, masing-masing 3 lokasi dan 3 ulangan. Untuk masing-masing sampel yang diambil dari pasar tradisional dan modern adalah 300 g. Pengujian fisiko-kimia sesuai dengan metode yang dikeluarkan oleh IPC (International Pepper Community), yaitu kadar air, abu, abu tak larut asam, minyak atsiri, piperin dan logam timbal (Pb). Untuk uji mikrobiologis terdiri dari TPC (Total Plate Count), kapang, jamur, Salmonella dan Escheria coli. Selain itu, dilakukanan analisis SEM (Scanning Electrone Microscope) untuk melihat profil morfologi permukaan. Hasil penelitian menunjukkan bahwa untuk kadar air, abu, minyak atsiri masih memenuhi kriteria SNI 01 3717 1995, kecuali kadar abu yang tidak larut asam dan kadar piperin. Cemaran mikrobiologi (TPC, kapang dan jamur) memenuhi kriteria, kecuali E. coli dan jamur pada sampel dari pasar tradisional Bogor. Salmonella memenuhi kriteria SNI untuk semua sampel, yaitu negatif. Cemaran logam berat (Pb) masih memenuhi ketentuan kriteria SNI. Deteksi pencampuran lada putih bubuk dengan bahan lain menggunakan metode kombinasi sifat fisiko-kimia dan SEM baru bisa mendeteksi adanya indikasi pencampuran, dan belum bisa menentukan jenis bahan percampurnya. Evaluation Of Quality of White Pepper Powder on Trade in Traditional and Modern Markets in Bogor and Jakarta.White pepper powder has very hygroscopic properties, so it is easily damaged, physically, chemically, or microbiologically. The purpose of this study was to determine the quality of white pepper powder, physically, chemically, and microbiologically from the traditional and modern markets of Bogor and Jakarta and to obtain information of mixing white pepper powder using other ingredients. The research methodology consists of several stages, namely sampling from traditional markets that are sold in bulk, and modern markets, which are packaged in plastic bottles; the sample has taken from 3 locations and 3 replications. For each sample taken from traditional and modern markets was 300 g. The physico-chemical tested according to the methods issued by the IPC, especially for moisture, ash content, acid insoluble ash, essential oil, piperine and timbal (Pb). The microbiological was tested, including TPC, mold, fungus, Salmonella and Escheria coli. In addition, an SEM analysis was performed to see the surface morphology profile. The results showed that moisture, ash content, ash insoluble in acid, volatile oil still meets the criteria of Indonesian National Standard, except for ash insoluble in acid and piperine content. Microbiological contamination fulfilled SNI criteria except E. coli and mold in samples from PT Bogor. Salmonella was fulfilled SNI criteria for all samples, which are given negative. Heavy metal (Pb) still fulfils the requirement in SNI criteria. Detection of mixing white pepper powder with other ingredients using a combination of physico-chemical properties and SEM can detect the indication of mixing and has not been able to determine the type of mixing material.

Design and effectiveness of pulsed electric fields towards seed disinfection

BACKGROUND Seeds harbor different microorganisms on their surfaces that degrade seed quality, thus causing an economic loss. Even though different approaches are available for the disinfection of seed surfaces, there is a need to develop environmentally friendly and sustainable technologies. A bench‐scale pulsed electric field (PEF) unit was designed to inactivate microflora of eight seeds after which the resultant vigor of the treated seeds was determined. RESULTS Significant reductions were obtained in endogenous natural and inoculated pathogenic (Alternaria brassica and Xanthomonas campestris pv. campestris, Drechslera graminea and Fusarium graminearum) microflora of seeds. The survival ratios of total aerobic mesophilic bacteria and of total mold and yeast decreased significantly for winter wheat and barley, parsley, onion, lettuce, tomato, and garden rocket with the PEF treatments of 240 and 960 J. A significant increase in germination ratio was observed for winter wheat and barley, lettuce, and tomato with 960 J. Germination energy increased for parsley with 240 J and for winter wheat and barley, lettuce, tomato, and garden rocket with 960 J. A better root development and seedling were found for winter barley. CONCLUSION PEFs are a viable option to both disinfect seed surfaces and improve seed vigor. © 2019 Society of Chemical Industry

“…As especiarias estão sujeitas à contaminação microbiana, principalmente quando são expostas às precárias condições, nas práticas agrícolas, secagem, armazenamento e transporte (GARBOWSKA; BERTHOLD-PLUTA; STASIAKROSANSKA, 2015). Por este motivo, estes produtos podem ser veículo de bactérias patogênicas quando adicionadas principalmente a alimentos que não passaram por cocção, ocasionando riscos à saúde do consumidor (NEI;ENOMOTO;NAKAMURA, 2015).…”
