N.A.B. process

The main features of the N.A.B. process applied industrially since 1956 are as follows ...

Note that the self-complementary and nonself-complementary processes of the same molecularity (n) give identical expressions for the van t Hoff enthalpy of the melting process, but not for the equilibrium constant. The factors in the expressions for K arise from the indistinguishability of 2A monomers in a process like A2 = 2A, while the A and B monomers in an AB = A + B process are distinguishable. 

To improve their functional and physico-chemical properties, dairy proteins have been modified by several methods (Haertle and Chobert, 1999), such as phosphorylation (Sitohy et al., 1995c), esterification (Chobert et al., 1995 Sitohy et al., 2001c), alkylation (Kitabatake et al., 1985), and reductive amidation (Mattarella et al., 1983) (see Section n.A., B.). However, most of these methods, using toxic chemicals, cannot be used in food processing. 

The enthalpy values of the AH N A HN" " process are similar for the studied complexes and are between 13 and 15kcal-mol. While the proton-donating ability of an acid decreases the rate of the reversible proton transfer diminishes and the activation energy increases. Thus a decrease of the potential well depth for the molecular complex causes an increase of the barrier for the proton transfer. One may conclude that the acidity of RAH defines mostly the depth of the potential well in the ionic complex while the barrier height depends on the hydrogen bond strength in the molecular complex, i.e. the distance between the bridge A, B atoms. 

Thus we have found two independent solutions by two different limit processes. In general any solution may be expressed in terms of M(a, b, x) and N(a, b, x), but it may be convenient to consider other ways of writing solutions. 

The last equality defines the rate v of the chemical reaction. In order to turn the relationships (3.2) into differential equations for the concentrations, the dependence of the rate v = n([A], [B],...) on the concentrations should be elucidated, which is commonly done experimentally. There are reactions for which the concentration dependence of v is particularly simple, namely the product of the reactant concentrations raised to some powers, v = k[A]a[B]b. In such cases, the sum of the exponents a + b + is called the order of the reaction. In fact, molecular collision arguments (Kreuzer, 1981) imply that if the expression (3.1) really describes the elementary molecular reaction process, then the reaction rate is... 

By plotting power dqjdt) against heat flow (q), the constants AH, k, m, n, A, B can be determined by a process of iteration. 

The adaptive estimation of the pseudo-inverse parameters a n) consists of the blocks C and E (Fig. 1) if the transformed noise ( ) has unknown properties. Bloek C performes the restoration of the posterior PDD function w a,n) from the data a (n) + (n). It includes methods and algorithms for the PDD function restoration from empirical data [8] which are based on empirical averaging. Beeause the noise is assumed to be a stationary process with zero mean value and the image parameters are constant, the PDD function w(a,n) converges, at least, to the real distribution. The posterior PDD funetion is used to built a back loop to block B and as a direct input for the estimator E. For the given estimation criteria f(a,d) an optimal estimation a (n) can be found from the expression...
