Food materials (ingredients or whole systems) can be composed of matter in one, two, or all three physical states solid (crystalline or amorphous or a combination of both), liquid, and gas. The crystalline state is an equilibrium solid state, whereas the amorphous glassy state is nonequilibrium solid state. The main transitions that occur between the physical states of materials of importance to foods are summarized by Roos and Karel (1991) and Roos (2002). The most important parameters affecting the physical state of foods, as well as their physicochemical properties and transition temperatures, are temperature, time, and water content (Slade and Levine, 1988 Roos, 1995). Pressure is not included in this list, as food materials usually exist under constant pressure conditions. [Pg.65]

The agreed subject of the discourse is the number of the elements, principles, or material ingredients of bodies. By focusing on the material ingredients Boyle may have been moving the reader toward his own me-... [Pg.44]

It is obvious that solvents should have a high stability and no reactivity towards the substances to be extracted since it is a precondition that the solvent can be used in many extraction cycles and since the genuine raw material ingredients should be recovered in unadulterated form. [Pg.49]

Chopped carbon flbers derived from either pitch or polyacrylonitrile are also used to provide reinforcement in friction materials but their lubricating tendency lowers the friction level. Although prices have come down in recent years, these reinforcements are quite expensive as a friction material ingredient. [Pg.1078]

Thus, we have three important concepts in the nineteenth-century scheme initiated by Lavoisier considerably earlier. The abstract element is a property bearer and owes its heritage to the Aristotelian element scheme. In addition to being a property bearer, the abstract element is an indestructible material ingredient of substances, and as we saw in the preceding discussion, there is a fundamental distinction between abstract element and simple substance. Abstract elements are unobservable, whereas simple substances such as sodium, chlorine, and oxygen are observed. It should be noted that in contemporary chemistry we only seem to retain the latter notion in that the term element now means what to a nineteenth-century chemist would have been called a simple substance ... [Pg.58]

This is because A has lost some of its weight in the time it takes for this reaction to proceed and for weighing to be made. The loss of significance of atomic weight as the material ingredient of an abstract element raises the question of how chemical properties are carried so that different isotopes may show the same chemical reaction. Of course, the answer lay, in making atomic number the new material ingredient. [Pg.65]

It is possible to trace out the raw materials/ingredients actually used, process conditions, or operational steps carried out (or mistakes made can be analysed easily) if all batch numbers are recorded properly. Necessary corrections can then be made for the next batch. [Pg.313]

Effect of Other Compounding Ingredients on Vulcanization. Other ingredients besides the elastomer and the cure system itself influence cure and scorch behavior. Usually the effect of a material on compound vulcanization is dependent upon the pH of the material. Ingredients which are basic in nature tend to accelerate the rate of both scorch and cure, whereas acidic materials exhibit the opposite effect. Reviews of the effect of antidegradants, fillers, process oils, and plasticizers are available (6,14,32,33). [Pg.7326]

In the test, the raw material is high content with Ag and As, supplied by a Yun nan metallurgical plant. The material ingredient is shown in Table HI, and the X-ray diffraction pattern is shown in Figure 2. According to Figure 2. As, Sb and Cu existing in the form of chemical compound, not in the form of elementary substance. At the same lime, they don t combine with other elements. Chemicals constitutes of raw material is shown in Table III. [Pg.258]
