Hardness methods for testing maize kernels.

摘要: Maize is a highly important crop to many countries around the world, through sale of maize domestic processors and subsequent production products also provides staple food subsistance farms in undeveloped countries. In countries, there have been long-term research efforts develop suitable hardness method that could assist industry improving efficiency processing as well possibly providing quality specification for growers, which attract premium. This paper focuses specifically on reviews number methodologies biochemical aspects contribute used internationally. Numerous foods are produced from maize, has described having an impact quality. However, basis measurement very general would apply any use country. From published literature, it appear one simpler methods measure grinding step followed by sieving step, using multiple sieve sizes. allow range within sample average particle size and/or coarse/fine ratio be calculated. Any these parameters easily reference values development near-infrared (NIR) spectroscopy calibrations. The precise NIR calibrations will provide excellent tool breeders, handlers, deliver specific cultivars case growers bulk loads thereby ensuring most efficient international processors. considers previous describing related hardness. Both starch protein affect hardness, with focusing storage proteins (zeins). content composition zein fractions Genotypes growing environment influence final and, lesser extent, composition. heritable trait hence, when desirable level finally agreed upon, breeders quickly able produce material levels required industry.
