1.	Discuss the various operations involved in turmeric processing. Or How turmeric powder is prepared from raw tarmeric?
Answer» For processing, all the turmeric, rhizomes are washed properly to remove soil sticking to it etc. For this purpose P.A.U. has developed a machine which can wash and polish turmeric. This machine can wash and polish simultaneously nearly 2.5 – 3.0 quintal turmeric per hour. After this step (i.e. washing etc.) turmeric is boiled so that fingers become soft and their colour becomes uniform. If boiling is done in open container it takes an hour but if boiled in pressure cooker it takes 20 minutes. After boiling, turmeric fingers are dried in sun so that moisture content is less than 10%. It takes nearly 15 days if strong sunlight is available. Now top layer of turmeric is removed by polishing. Then it is grounded in the grinder (hammer mill). This way 100 kg fresh turmeric gives 15-20 kg. powdered turmeric.
