There is a continual quest for a natural flocculant for juice clarification in the production of organic sugar as the use of synthetic polyelectrolytes is barred. The clarifying property of the seeds of drumstick tree (Moringa oleifera) in food and water purification processes is well known in rural areas of developing countries and has been recently exploited in full scale water treatment plants in Africa. Laboratory tests showed that a sieved solution of crushed seeds of Moringa oleifera, when applied at 0.16 per cent on limed juice produced a solution (52 per cent) clearer than one without a flocculant, but the mud produced was twice in volume. The latter could be reduced by 10 per cent by using bentonite at 0.05 per cent on juice, with the added benefit of reducing the juice turbidity by 10 per cent. The clarifying properties of the edible fruit of Cordia myxa were also investigated. Laboratory tests showed that when solution of Cordia myxa fruit was added between 0.016 and 0.04 per cent on limed juice, up to 42 per cent clearer solution could be obtained with a reudction of 9 per cent in mud volume. Pilot tests confirmed that Cordia myxa solution applied for one hour at 0.02 per cent on limed juice actually withheld the rising tendency in the clear juice turbidity during that period | |
