Technological factors

For fermentation, the pretreated vegetables are then placed in suitable fermeu-tation vessels. Due to the respective product, the plant size and the applied technology, these vessels may range from 100-1 drums to tanks or silos with up to 100-ton capacity. Filling must be done very carefully. In order to achieve favourable 

Under these conditions, a spontaneous fermentation process usually begins immediately. The best products will be achieved at fermentation tanperatures between 15 and 20 °C. The fermentation time depends primarily on the temperature, the type of 

The final fermented product (pH 4.1) may either be distributed fresh, packaged or unpackaged, or pasteurized in pouches, cans or jars. In the latter case, the fermented vegetables are first blanched and then filled into the container, poured and after closing subjected to a gentle pasteurization. For victuals that easily soften, the original fermentation liquid should be replaced by a brine containing certain amount of sodium chloride and lactic acid in order to top the containers. 

If the fermented fruit and vegetables are to be distributed unpasteurized, it is essential that all fermentable carbohydrates have been metabolized. Otherwise, a secondary fermentation may occur caused by yeasts and resulting in gaseous spoilage, brine turbidity and probably an alcoholic fermentation. In the case of cucumbers, secondary fermentation may cause bloater formation (Daeschel Fleming, 1984). 

In the case of pasteurized products, fermentation may be interrupted as soon as the pH value reaches 4.1. For that reason the goods are blanched, canned, topped with fermentation liquid or salt and sometimes herbs, spices and/or vine containing brine, and pasteurized. In order to achieve less heat treated and therefore better-quality products, as weU as to save energy, the traditional pasteurization methods of trial and error should be replaced by evaluated and defined pasteurization processes using P-value calculation. However, the application is stiU difficult, due to the lack of information especially about the heat inactivation kinetics of quality-relevant enzymes like pecti-nolytic enzymes or lipoxygenases (Buckenhueskes, Gierschner Hammes, 1988).

The betalains serve as another example. They are very sensitive to different technological factors. They can only be maintained in foods with short shelf lives, produced with minimum heat treatment, and packaged in a dry state under reduced levels of light, oxygen, and humidity. Betalains have several applications in gelatin desserts, confectionery, dry mixes, poultry, dairy, and meat products. ...

There are also some technological factors that influence the quality of the polymer. The design of the reactors, the flow of the molten polymer and the way of heating the systems are decisive for quality and performance [28], Valves, tube turns, in- and out-take flanges, mixing elements and welding seams are often...

Identify and promote the implementation of effective non-technological approaches to pollution prevention. This research area includes socioeconomic and institutional factors that motivate behavior and foster changes in behavior as they relate to incentives for adopting pollution prevention techniques. Research is needed to understand the roles of non-technological factors in implementing pollution prevention approaches and their impact on the effectiveness of pollution prevention programs. 

Some flawless analytical methods do exist but more are needed. Quantitative extraction of all the phenolic compounds from skins and seeds is not possible however we have developed a standard, reproducible procedure. Using a solvent with physicochemical properties similar to wine, one performs three cold extractions followed by two warm ones. This gives an estimate of the total phenols and an idea of their solubilities—an important technological factor. Our work, done in 1969-1972 involved the two principal red varieties of Bordeaux (Merlot and Cabemet-Sauvignon) from two vineyards. One ( ) is a Grand Cru of the Medoc region characterized by fast maturation, and the other (SC) matures more slowly (46, 47). 

However, granulometric composition is also dependent on several technological factors, more specifically, the properties of source material and binder liquid, their ratio and particle size of material on the plate. 

However the search for solutions is time-consuming even with modem computers, and results have only limited value, because they do not provide an understanding of the influence of the main geometrical and technological factors on the qualitative pattern of the process. Therefore, models of the flow in channels of relatively simple shape have became very popular.269"271...

The morphology from a specific impulse point of view is given in a later section. Extensive analyses are required before a proper selection can be made for a given mission. In the following section the fundamental and technological factors which prevail in the choice of specific propellants will be reviewed so that an effective screening of all possible compounds can be made. Although much of the fundamental discussions will pertain to solid propellants, the emphasis will be upon liquid systems.

To achieve a catalytic layer on base materials is the core process for DSA-electrode fabrication. To ensure the layer stability, it is important to try to make the layer better adhesion with the base surface. We have tried several methods in the electrode preparation, including pretreatment, pyrolysis technologies, and electrodeposition. Till now, our research revealed that the electrode service life and the behaviors have been influenced by the electrode preparation methods and technological factors.
