    Notes: : Nuclear magnetic resonance (NMR) was used to investigate the spatial distribution of the non-frozen water in foods during freezing and frozen storage. For samples such as beef, orange juice, and dough, their NMR responses were characterized and studied over temperature and during storage at subzero temperatures. The content of liquid-like components, such as unfrozen water, was measured in the temperature range between 20 and -40 °C. Ice formation led to a significant decrease of the amount of liquid-like components. This also was gradually diminished during storage, due to slow crystallization. Moreover, 1- and 2-dimensional images of the proton distributions in the frozen samples were obtained by single point ramped imaging with T1 enhancement (SPRITE). The use of SPRITE to examine frozen foods allowed a spatial evaluation of liquid-like spins during freezing and storage.

    Cryoprotection of protein by highly concentrated branched oligosaccharides (2003)

    Notes: Cryoprotection of protein by highly concentrated branched oligosaccharides (HBOS) was investigated by using a model solution containing bovine serum albumin (BSA). The glass transition temperature of the BSA solution with HBOS, determined by modulated differential scanning calorimetry, was −16.1 °C, which is higher than that of sucrose at either 4 or 8% concentration by weight (−27.2 °C). Also, changes in the unfrozen water fraction and their mobilities, determined by nuclear magnetic resonance, were used as indices of protein stabilization. The results revealed that the amount of unfrozen water increased whereas the mobility was decreased by addition of HBOS. Thus we propose that the cryoprotection effect can occur by preserving the protein in a rigid structure formed by the water and the cryoprotectant HBOS.

    STUDY OF RESTRICTED DIFFUSION BY NMR IN FREEZE-DRIED STARCH GELS (1997)

    Notes: Pulsed-gradient spin-echo NMR diffraction patterns were used to determine the pore size in freeze-dried corn starch gels (7 and 12% w/w) with octane used as the probe molecule. The pore diameters are approximately 200 μm and appear isotropic for this measurement. This technique can provide an effective measure of the pore size without altering the sample structure.

    Notes: Summary The responses of two egg-plant varieties to irrigation rhythm and water supply based on daily potential evapotranspiration were performed on St-Paul silt loam. Results showed that a shorter irrigation rhythm gives the best production in terms of fruit yield (Table 1). Daily irrigation gives a leaf blade with a lower specific weight than the bi-weekly irrigation rhythm during the whole sampling period (Fig. 1). When we compared 4 quantities of water representing 40 to 100% of the potential evapotranspiration, the best results in terms of fruit yield were obtained with the irrigation giving 80% of the potential evapotranspiration (Table 2). But there is no significant difference between the specific leaf weights (Fig. 2). When we observed the varietal behaviour we found that the cultivar ‘Violette de Barbentane’ gives a production 20% higher than that of ‘Ronde de Valence’. But the water potential and transpiration resistance of leaves are not very different for the two varieties (Figs. 5 and 6).

    Effects of irrigation rhythm on growth, fruit-set, yield and quality of egg plant (Solanum melongena) in southern France (1976)

    Notes: Summary Responses of egg plant crop to 3 irrigation rhythms based on the daily potential evapotranspiration were investigated. Results showed that the shorter the rhythm (5 times per week) the better the plant growth expressed in terms of plant length (Fig. 2) and/or yield shown as fruit number (Fig. 3) or fruit fresh weight (Fig. 4). The twice per week rhythm gave the medium, whereas the 10 days one gave the least plant growth and yield. Also the frequent rhythm (5 times per week) gave an earlier crop presented as flower-setting (Table 2). The three rhythms did not show an effect on crop quality expressed as mineral content of leaf blades, petioles or fruits. But results showed that leaf blades usually have higher mineral content than the fruits especially with the micro elements. re]19750305
