OBSTACLES TO THE SUCCESSFUL INTRODUCTION OF RICE ENRICHMENT BY PREMIX METHOD

The Obstacles to the successful  introduction  of rice enrichment  by premix method includes the following:
  1. The cost of  the imported premix
  2. The  difficulty of ensuring that the premix is added to rice in correct proportion in the mill.
  3. The slightly greater  cost of  enriched rice  as compared with that of  ordinary rice,  which affects its sales to lower income groups.
  4. Loss of added  vitamins, which  may occur when enriched  rice is cooked in excess water that  is  subsequently  discarded according to  current practice in  some  rice eating countries. 
  5. Issues related to standards  and analysis,  part  insularly  of  imported  rice.
  6. Lack of  knowledge about  the lose  of  added  nutrients during storage FAO (1854).
Under-milling has been employed to retain  B vitamins in milled rice, but the shelf-life of under-milled  rice is shorter than that of milled rice and the product  is less white (FAO  1954). Some  consumers re-milled the under –milled rice to remove  the rancid outer layer  and to make the rice white, with an accompanying lost of B vitamins. Mille rice  has  also been used for enrichment programmes for  vitamin A as  well as B vitamins  in Thailand and Philippines FAO (1954).
