Scandinavian Workshop on Imaging Food Quality 2011 Quantification of Microstructures in Freeze-dried Carrots Using Μct

The characterization of the microstructures of freeze-dried food products determines the speed of and the properties after rehydration. The pore size distribution is an important characteristic of such textures. Spatial homogeneity and the orientation of voids and cracks inside the samples are studied.

Rehydration characteristics of freeze-dried avocado (Persea americana)

The avocado is a tropical fruit whose nutritional value is due mainly to its high lipid content. The aim of this work was to evaluate the rehydration of freeze-dried avocado (variety Collinson) powder and slices. The rehydration kinetics was determined using an experimental apparatus that monitored the volume of water absorbed by the sample with the time. Peleg and Weibull equations were used t...

Quality parameters in convective dehydrated carrots blanched by ultrasound and conventional treatment.

The effect of previous ultrasound and conventional blanching treatments on drying and quality parameters (2-furoylmethyl-amino acids -as indicators of lysine and arginine participation in the Maillard reaction-, carbohydrates, total polyphenols, protein profile, rehydration ratio, microstructure changes) of convective dehydrated carrots has been assessed. The most striking feature was the influ...

Comparative study of three drying methods: freeze, hot air- assisted freeze and infrared-assisted freeze modes

The dehydration tests were conducted at three drying methods to evaluate the drying curves and the energy uptake. Apple (Malus domestica L.) cubes were dried under different processing conditions applying freeze drying (FD), freeze drying assisted by hot air and freeze drying assisted by infrared radiation. Control samples were produced using regular freeze drying without the pre-drying. Hot ai...

Electrohydrodynamic Drying of Carrot Slices

Carrots have one of the highest levels of carotene, and they are rich in vitamins, fiber and minerals. However, since fresh carrots wilt rapidly after harvest under inappropriate storage conditions, drying has been used to improve their shelf life and retain nutritional quality. Therefore, to further investigate the potential of this method, carrot slices were dried in an EHD system in order to...
