Isothermal crystallization behaviour of natural and recombined creams and their bulk milk fats was examined at 5 °C using differential scanning calorimetry to analyze crystallization kinetics, X-ray diffraction to elucidate the crystallization mecha
Building upon the scope of its predecessor, Dairy Science and Technology, Second Edition offers the latest information on the efficient transformation of milk into high-quality products. It focuses on the principles of physical, chemical, enzymatic,

Compression and wire-cutting experiments on dispersions of fully hydrogenated palm oil in sunflower oil with varying fraction solid fat were carried out to establish which parameters are important for the large deformation behavior of fat crystal net

Dispersions of hydrogenated palm oil (HP) in sunflower oil were crystallized in a scraped-surface heat exchanger (SSHE), where local strain rates are high. The HP crystallized completely or partially under shear, possibly followed by crystallization

The effects of pH and various additives on the precipitation and (re)solubility at pH 7 of potato proteins from industrial potato fruit juice (PFJ) were studied. The use of various strong and weak acids did not result in differences in protein precip

The influence of casein micelle composition on the extent of chymosin association is described. The association of chymosin with artificial micelles, made with combinations of α s -or β -casein with κ -casein, in a compositional range of α s or

The structure and stability of the casein micelle are fairly well known under conditions as in milk. However, much less is known and understood for conditions as are prevalent in ice cream. In this study it was observed that structure and behaviour o

The association of hen eggs’ lysozyme with caseins was studied by using three casein substrates: (I) solutions of the various caseins, (II) artificially made casein micelles of various compositions and (III) caseins adsorbed onto soya-oil emulsion

The effects of gelation temperature (20, 30 or 40 °C), assay temperature, concentration of glucono-δ-lactone (GDL) added, and NaCl concentration on the rheological properties of acid casein gels were studied at small and large deformations. Gels pr

The flavour of cheese develops partly due to retained milk-clotting enzymes in curd during cheese ripening. In this paper, the influence of the casein micelle composition, and the pH of the micelle solution on the amount of chymosin adsorbed onto cas
