“…The statistical results denote that longer blanching time generates lower water content. The pretreatment of the blanching process in a citric acid solution can accelerate water transfer (Ananingsih et al, 2017). The water content of food products is influenced by the cooking process because the water content will decrease during the cooking process.…”

Black saffron (Curcuma aeruginosa Roxb.) belongs to the family of Zingiberaceae is one of rhizomes widely used as raw material in Indonesian Traditional Medicines. Black saffron (BS) contains some bioactive compounds responsible for certain biological activities including antioxidant. Blanching has been reported to increase the antioxidant activity of BS. This study aims to formulate BS containing high antioxidant activity. This research was performed by varying blanching medium (citric acid and aquadest) and blanching time (0; 2.5; 5; 7.5 and 10 min). The fabrication stage of BS powder included peeling, cleaning, blanching, slicing drying, grinding, and sieving. After that, the treated BS was analyzed for the antioxidant activity, total phenolic, total flavonoid, tannin, crude fiber, and water contents. BS powder subjected to blanching process showed better antioxidant activity than that without blanching process. Blanching using citric acid media 0.05% for 5 min showed the best antioxidant activities, as indicated by high contents of total phenolic, total flavonoid, and tannins. Powdered BS is potential to be used as materials to be applied as fortifying agents in food products.

“…While the size of 100 and 200 mesh would gave good ridge characteristics. The higher the sieve size, the lower the colour contrast level [18]. It might be due to the smaller particle size, the surface area of the material will increase [19,20].…”

This study was aimed to develop an environmental-friendly fingerprint visualization using turmeric herb. The turmeric powder size was in the range of 60-200 mesh. The dusting method was done by applying turmeric powder to glass surface, aluminum foil, transparent plastic, plastic cups and compact disk (CD) surfaces that have sebum content from fingerprint samples. This study was also compared with the small particle reagent (SPR) of ninhydrin. The SPR method was done by spraying ninhydrin solution on A4 white paper and doorslag paper. The results of this study indicated that form of fingerprint obtained has the following pattern: radial loop (16.6 %), ulnar loop (63.3 %), tented arch (1.6 %), twinted loop (1.6 %) and plain whorl (16.6 %). The results showed that the turmeric powder dusting method gave a low contrast with yellow colour while ninhydrin SPR provides high contrast with Ruhemann’s purple.

“…Tahapan pengolahan rimpang jahe segar menjadi simplisia jahe dilakukan melalui beberapa tahapan yaitu proses sortasi, pencucian, pencacahan atau pemotongan, pengeringan, sortasi akhir, pengemasan dan penyimpanan [11]. Selain itu, pemanenan yang tidak tepat dapat menyebabkan rimpang jahe mudah mengalami kerusakan fisiologis sehingga dapat menurunkan mutu, oleh karena itu perlu dilakukan penanganan lebih lanjut, salah satunya adalah proses pengeringan [12]. Salah satu tujuan pengeringan tidak hanya untuk meningkatkan nilai jual tetapi juga untuk mengatasi terjadinya pembusukan dan kelebihan pasokan pada saat musim panen [13].…”

<p>Pengeringan merupakan alternatif yang cocok untuk pengelolaan pasca panen, terutama di negara seperti Indonesia yang fasilitas distribusi dan penanganan pasca panennya kurang baik. Produk pertanian berupa tanaman herbal memerlukan penanganan pasca panen khusus, agar produk dapat disimpan dalam waktu yang lama tanpa mengurangi aroma. Salah satu produk pertanian tanaman herbal adalah jahe. Dalam proses pengolahan pasca panen, untuk mendapatkan jahe kering, dibutuhkan teknik pengeringan dengan temperatur yang rendah agar tekstur dari produk akhir yang dihasilkan tidak banyak berubah. Tujuan dari penelitian ini adalah mengaplikasikan sistem dehumidifikasi pada mesin pengering jahe untuk mendapatkan temperatur pengeringan jahe yang sesuai namun efisien. Metode yang digunakan di dalam penelitian ini adalah metode eksperimental, dimana temperatur pengeringan dikontrol pada suhu 40°C dengan waktu pengeringan selama 7 jam. Hasilnya, jahe segar yang dikeringkan dengan pengering sistem dehumidifikasi menghasilkan penurunan berat rata-rata 80,66% dengan kandungan kadar air rata-rata sebesar 9,2%.</p>
