The two main assumptions underlying the derivation of Eq. (5) are (1) thermodynamic equilibrium and (2) conditions of constant temperature and pressure. These assumptions, especially assumption number 1, however, are often violated in food systems. Most foods are nonequilibrium systems. The complex nature of food systems (i.e., multicomponent and multiphase) lends itself readily to conditions of nonequilibrium. Many food systems, such as baked products, are not in equilibrium because they experience various physical, chemical, and microbiological changes over time. Other food products, such as butter (a water-in-oil emulsion) and mayonnaise (an oil-in-water emulsion), are produced as nonequilibrium systems, stabilized by the use of emulsifying agents. Some food products violate the assumption of equilibrium because they exhibit hysteresis (the final c/w value is dependent on the path taken, e.g., desorption or adsorption) or delayed crystallization (i.e., lactose crystallization in ice cream and powdered milk). In the case of hysteresis, the final c/w value should be independent of the path taken and should only be dependent on temperature, pressure, and composition (i.e.,...

The principal ingredients of the massive chocolate product are the cocoa mass, cocoa butter, ground sugar and milk powder. Typical compositions of massive chocolate products are shovm in Tab. 5.20. 

The particle size of the powders, which is affected by milk composition and the solid-fat content of the milk fat, also affects the suitability of powders for chocolate manufacture (Keogh et al., 2002). By increasing the spray nozzle size for the concentrate and increasing the air outlet temperature of the dryer, the particle size of milk powders can be increased (Keogh et al., 2004). This makes milk powders more suitable for chocolate manufacture. 

The product composition, i.e. the proportion between protein and lactose in the final product, may be controlled from the central control room. Thus the factory is able to produce protein powder with compositions varying from approx. 35% protein of total solids to approx. 85% protein of total solids. The first mentioned is a product with a composition like cheap skim-milk powder, whereas the latter is an expensive product used for baby-food and dietetic food. 

Diets. Bovine-based nonfat powdered milk was purchased from Pet-Ag (Hampshire, IL). Fat blends which constituted 47% of total dietary energy were composed of a base fat free of LC-PUFA (currently used in Enfanul, Mead-Johnson Nutri-tionals, Evansville, IN) and of LC-PUFA fats derived from DHA and AA single-cell oils (DHASCO and ARASCO). They were mixed together initially at a DHA/AA ratio of 1 2. Specific amounts of this LC-PUFA mixture were then incorporated into the base fat to obtain DHA and AA levels corresponding to 1 (Diet 1), 2 (Diet 2) and 5 (Diet 5) times the amount provided in term infant formulas in the United States. Diet 0 was the control formula it contained only the base fat and was free of LC-PUFA. Amounts of DHA/AA in Diets 1,2 and 5 were 17 mg/34 mg, 34 mg/68 mg and 85 mg/170 mg per 100 kcal, respectively. The fatty acid composition of the four formulas is presented in Figure 1. 

Barium carbonate also reacts with titania to form barium titanate [12047-27-7] BaTiO, a ferroelectric material with a very high dielectric constant (see Ferroelectrics). Barium titanate is best manufactured as a single-phase composition by a soHd-state sintering technique. The asymmetrical perovskite stmcture of the titanate develops a potential difference when compressed in specific crystallographic directions, and vice versa. This material is most widely used for its strong piezoelectric characteristics in transducers for ultrasonic technical appHcations such as the emulsification of Hquids, mixing of powders and paints, and homogenization of milk, or in sonar devices (see Piezoelectrics Ultrasonics). 

Variety of biochemical composition and physical features of milk, as well as compound forms of mineral components foreordain necessity to develop the analytical procedures, in which initial sample state suffers minimum change. Absence of dried milk reference standai ds (RSMs) is an obstacle to use nondestructive XRF for solving the given analytical task. In this communication results of nondestmctive x-ray fluorescence determination of Na, Mg, Al, Si, P, S, Cl, K, Ca, Cr, Mn, Fe, Ni, Cu, Zn, Rb, Sr, Zr in dried milk powders of limited mass (less than 2 g), obtained with using plant RSMs to calibrate, ai e discussed. 

Four reconstituted milks were prepared by blending hydrated skim milk powder (35g/L) with four different emulsions (35g/L) differing by composition of the fat-water interface. Whole reconstituted milks were coded MP (milk proteins), BCAS ( 6-casein), and BLG5 (j6-lactoglobulin 5 g/L).

International classification A23C9/12, A23C9/127, A23C9/133, A23C11/10 The innovative composition includes milk base and powdered concentrate of Jerusalem artichoke. 

The composition described includes sugar, cocoa powder, stabilizer, Jerusalem artichoke powder, and milk base. The pudding has improved taste, higher biological value, and curative and prophylactic properties. 

Figure 13.1 is a flow diagram for the traditional processes for the manufacture of WMP, SMP, and BMP. An alternate process for the manufacture of WMP that involves blending highly heated cream and low heat-treated skim milk concentrate prior to drying, was described by Hols and Van Mil (1991). The recommended standards for WMP, SMP and BMP, as well as average composition of the powders, are shown in Table 13.1.

Figure 19.13 depicts the meltdown behaviour of ice creams with different compositions. In experimental situations, 50% of the skim milk powder was replaced by whey protein in the form of either conventional whey protein or WPP (Koxholt et al. 2001). 

As a result of the close packing of the aqueous-phase droplets, the composition of the water phase is critical. Protein concentrates, caseinate, gelling agents, and special emulsihers have been recommended to simplify the emulsification and to stabilize the end product (93-98). For manufacture, the basic material for production is a mix that is chemically identical to the end product. This mix consists of mUkfat in the form of butter, butter oil, and fractionated butter oil or cream, in many cases, it also has milk solids, milk concentrates (including dissolved milk powder and caseinates), and emulsifiers (see Figure 10) (81). The fat mix (i.e., butter, butter oil, etc.) is melted and pasteurized. 

The whey powder (from bovine milk) used in this experiment was purchased from Sigma Chemical Co. (St. Louis, MO, USA). The chemical composition of whey protein is shown in Table 1. Samples were prepared by diluting the appropriate amount of whey powder with water. The concentration of the samples remained at approximately 200,000 ppm. The standard chemicals of a-lactalbumin (Type III deplete, form bovine milk, approximately 85%), p-lactoglobulin (form bovine milk, approximately 90%), and BSA were purchased from Sigma Chemical Co. Standard protein solutions were prepared in water. Standard solutions were made for each protein of 10 mg dissolved in 1 L with water. The water was filtered with HA 0.5-pm membranes (Division...
