O presente trabalho teve como objetivo analisar e caracterizar o mosto e o suco de uva das variedades BRS-Cora e Isabel Precoce nas condições do Submédio do Vale do S„o Francisco na segunda safra de 2009 que, depois de colhidas e transportadas para a Embrapa Semi-árido, permaneceram a 10∫ por 24 horas, para a retirada do calor de campo. |

Caking is associated with the consolidation of dry powder and granules, leading to losses of function and/or quality. It has been object of studies in the pharmaceutical, food and fertiliser areas since 1920's because of its significant impact on product quality and value. Caking has been described as a three-step event consisting of sorption-dissolution-recrystallisation phases and constitutes a critical factor in fertilisers losses during storage while also hampering fertiliser application. Current methods for the evaluation of water sorption dynamics are expensive, time-consuming and/or inaccurate. This manuscript describes an unprecedented application of low-field 1H NMR relaxometry for the kinetic study of humidity uptake, in real-time, by urea mixed with different concentrations of an anti-caking agent (zeolite). The proposed method allows to follow the water uptake in different domains of the mixed fertiliser/zeolite samples. To our knowledge, this dynamic has not been observed and quantified so far in real-time. Furthermore, we presented the use of 2D-ILT for kinetic studies, being the first dimension the usual transverse relaxation and the second dimension the kinetic one. With this approach, the NMR relaxation times T2 correlated to time constants associated with the uptake kinetics of the water. This method could be extended to several kinetic studies and experiments with temperature variation. Depending on the kinetics of the studied process, the kernel of the Laplace transform must be suitably adapted.
