Light processing

The role of cerium in these lighting phosphors is not as the emitting atom but rather as the sensitizer. The initial step in the lighting process is the efficient absorption of the 254 nm emission Ce ", with broad absorption bands in the uv, is very suitable. This absorbed energy is then transferred to the sublattice within the crystalline phosphor eventually the activator ion is fed and emission results. Cerium, as a sensitizer ion, is compatible in crystal lattices with other lanthanide ions, such as Eu and Tb, the usual activator atoms. 

Since polychloroprene crystallizes under stress, fine particle size carbon black is not ordinarily needed or used to enhance tensile strength. More frequently, mineral fillers, for example clay, can be added to reduce cost. A light process oil, free of polycycHc aromatics, can be used to improve the flexibihty or hand of films. On the other hand, an ester plasticizer can be used to improve low temperature properties (161).

Physicochemical Changes and Treatments for Lightly Processed Fruits and Vegetables... 

Because of the great variations in fruit and vegetable commodities and the ways in which they are prepared for consumption, it is almost impossible to make an all-inclusive, precise definition of lightly-processed, or... 

The degree of stabilization required in a lightly processed food also depends upon the market to which it is being sent. Generally, there is more product control in institutional and remanufacturing markets than in restaurants. Retail grocery and produce markets provide the least control over product handling abuse. 

Regardless of the kind of process-distribution system that is used, the same quality factors must be maintained in the lightly-processed products, namely flavor, texture, and appearance. Microbiological quality and nutritional quality are also important, but they will not be dealt with in this communication. 

It is not uncommon to find that a treatment which enhances the stability of one quality factor causes another factor to become unacceptable. A chemical additive, such as calcium chloride, may improve the textural quality of a fruit product, but it can also produce unacceptable flavors. Blanching, to inactivate enzymes that cause darkening, destroys the fresh-like textural quality that is desired in lightly processed fruits and vegetables.
