Rice Quality
A Guide to Rice Properties and Analysis
by Kshirod R. Bhattacharya

Rice Quality: A Guide to Rice Properties and Analysis covers the variability in rice characteristics and their effects on rice quality. It provides an understanding of rice properties and their significance, essential for the provision of high-quality products.

Coverage includes:

  • examines the physical properties of rice, such as grain appearance and density and friction
  • investigates the ageing of rice and its cooking and eating quality
  • the product making and nutritional aspects of rice
  • specialty rices and rice breeding
  • rice quality analysis
  • rice quality test procedures
  • and much more
