And spoiling

Bioethanol production by yeasts is widely used for biodegradation of potato. However, yeasts cannot ferment starch directly, and a two-step enzymatic reaction to glucose is necessary. Different potato wastes such as industrial residues, low-grade potatoes, and spoiled potatoes can be used for acetone/ethanol production (Nimcevic et al., 1998). They used whole potato media... 

Oil shales comprise clastic, carbonate, organic, and minor sulphide fractions. Each of these fractions generates several types of environmentally harmful wastes, as evidenced by information from the world s largest industrial consumer of such shales Estonia. In general, mining wastes and spoil may yield acidic or alkaline leachates, depending on the relative proportions of sulphide and carbonate minerals present. 

There are many potential uses for recombinant DNA technology. Agricultural products, as is discussed in Chapter 15, can be made bug-resistant and spoil-resistant. The technology may also be used to treat genetic disorders, such as sickle-cell anemia, muscular dystrophy, cystic fibrosis, and lupus, and may even address the question of why our bodies deteriorate with age. 

The alert panel supervisor will also come to know about each regular panelist s ability to detect the many off-flavors that could possibly occur in citrus products. Of primary concern, other than the common sweet and sour flavor attributes, are the panelists abilities to specifically identify (a) bitterness (naringin and/or limonin induced), (b) heated, processed or pumpout off-flavor, (c) excess peel oily, (d) excess and/or poor essency flavor, and (e) the following off-flavors cardboard, tallowy, castor oil, diacetyl or buttermilk, green or immature, overmature or stale fruit, and spoiled fruit.

Concentrate is extremely perishable. Most maple operations utilize RO machines that are capable of providing only slightly more concentrate per hour than can be utilized by the evaporator. In practice, most producers will concentrate a small amount of sap, start the evaporator, and continue to run the RO during boiling so that the concentrate is not allowed to build up and spoil. 

A product with a higher melting point is necessary for consumer acceptance. In addition, triacylglycerides that are more unsaturated tend to spoil more rapidly. This spoilage is due to oxidation caused by radical reactions. (This is an example of the au-toxidation process described in Section 21.8 and the Focus On box Vitamin E and Lipid Autoxidation on page 937. The hydrogens on the allylic carbons of unsaturated fatty acid residues are more readily abstracted because the resulting radicals are stabilized by resonance, so these compounds oxidize and spoil faster.) However, there is a trade-off, because it has been demonstrated that saturated fats have more deleterious health consequences than unsaturated fats do.

We often want to prevent or retard free-radical reactions. For example, oxygen in the air oxidizes and spoils foods, solvents, and other compounds mostly by free-radical chain reactions. Chemical intermediates may decompose or polymerize by free-radical chain reactions. Even the cells in living systems are damaged by radical reactions, which can lead to aging, cancerous mutations, or cell death.

Follow this procedure 1. Put 4 tablespoonfuls of coconut or olive oil into the small pot and add 1 test tubeful of sodium hydroxide solution to it. Carefully heat the liquid over the alcohol burner, using a small flame. Stir the mixture constantly and continue heating it until it becomes a thick paste. Caution Be sure you wear goggles. Sodium hydroxide bums skin and spoils clothing. If any sodium hydroxide gets on your skin, wash it immediately with cool water. Remember, too, that the pot should never again be used for cooking.

It required considerable experience to fix the plates into their proper places and to avoid them attracting so strongly that relative movements became too difficult. In these circumstances frictional movements between the plates can have a very bad influence upon the quality of the surfaces.i However, if the distance is too large and the attraction not strong enough, the plates may lose contact before the apparatus is evacuated and this almost certainly brings dust-particles between the plates and spoils the measurement. The viscosity of the air makes the manipulation more easy by providing an air-cushion between the plates that disappears only slowly.
