Trading quality and breadmaking performance of wheat treated with natural zeolite and diatomaceous earthDOI: 10.2298/apt1142001b Keywords: inert dust , wheat , flour , bread Abstract: The aim of study was to investigate the influence of naturally occurring zeolite and diatomaceous earth, as inert dusts approved for insect pest control in certified organic crop production, on trading and breadmaking quality of treated wheat. The treatments significantly reduced the trading quality of wheat which was reflected through lowering of test weight. This effect was more marked in the case of low-vitreous wheat rather than in high-vitreous one. Investigation of rheological properties of flours made from the treated wheat demonstrated that treatments with natural zeolite and diatomaceous earth at all applied doses significantly increased the water absorption, which consequently increased the bread yield. However, these changes in the flour properties were not high enough to modify the quality attributes of bread as was shown by instrumentally measuring crumb hardness and springiness as well as sensory evaluation.
