Abstract
Moringa oleifera memiliki banyak manfaat untuk produk pangan, kosmetik dan medis. Pengolahan daun M. oleifera terdiri dari tahap pencucian dengan air bersih dan larutan garam. Tujuan dari penelitian ini adalah untuk mengetahui pengaruh metode pencucian terhadap higienitas dan kualitas daun M. oleifera industri. Dalam penelitian ini, empat jenis metode pencucian daun M. oleifera diterapkan untuk mendapatkan perbandingan antara beberapa jenis sumber air yaitu air sumur, PDAM, air isi ulang dan air kemasan (AMDK). Selanjutnya, dua jenis sumber garam juga diterapkan yaitu garam dapur dan garam krosok. Parameter higienitas M. oleifera adalah jumlah lempeng total (TPC), MPN coliform, keberadaan Salmonella sp., dan jumlah koloni Staphylococcus aureus. Sementara itu, kapasitas antioksidan dan tingkat flavonoid juga ditentukan sebagai tingkat kualitas daun M. oleifera. Hasil penelitian menunjukkan bahwa metode pencucian yang paling efektif adalah menggunakan kombinasi AMDK dan garam dapur dengan jumlah total mikroba (TPC), nilai MPN, S. aureus masing-masing sebesar 0,9 × 104 CFU / gram, 0,55 / gram, 0,2 × 102 CFU / gram dengan semua hasil positif dalam uji Salmonella sp. Kualitas M. oleifera terbaik dicapai dengan mencuci daun dengan air isi ulang dan garam krosok dengan jumlah tingkat kapasitas flavonoid dan antioksidan masing-masing 8,57 mgQE / gram dan 69%.

Moringa oleifera has many function such as food, cosmetic and medical product. M. oleifera leaves processing consists of washing step by clean water and salt solution. The purpose of the study was to determine the effect of washing method to hygienic and quality of industrial M. oleifera leaves. In this study, four types of M. oleifera leaves washing method were applied to obtain comparation between several types of water sources namely well water, government water treatment, refilled water and bottled water. Further, two types of salt sources were as well applied namely commercial salt and raw salt. The parameter of M. oleifera hygienic were total plate count, MPN coliform, Salmonella sp. present, and Staphylococcus aureus cell number. Meanwhile, the antioxidant capacity and flavonoid level were as well determine as quality level of M. oleifera leaves. The results showed that the most effective washing method were using a combination bottled water and commercial salt with total plate count, MPN, S. aureus value as 0.9 × 104 CFU/ gram, 0.55/ gram, 0.2 × 102 respectively with all positive results in Salmonella sp. test. The best M. oleifera quality was achieved by washing the leaves with refilled water and raw salt with number of level of flavonoid and antioxidant capacity percentage were 8.57 mgQE/ gram and 69% respectively.
