Main nut

The Black Sea coastal region of Turkey is an unfortunate area as it also received an appreciable dose of radioactive fall-out after the Chernobyl accident. After this accident almost a whole years crops (mainly nuts and tea leaves) had to be collected and destroyed. So this barrels story was only an additional incident to the misfortune in that part of the country. In both of these almost concurrent occurrences, the Black Sea coast pec le in Turkey suffered economically, ecologically, socially and perhaps paid with their health for the mistakes of others. Such incidents may happen to any nation or community anytime, perhaps even with more drastic end-results. This shows that the scientists and politicians of the wwld must work together to stop illegitimate transport of dangerous chemicals, and minimize risks of accidents which may create environmental disasters with transboundary transport possibilities.

Fats and oils may be synthesized in enantiomerically pure forms in the laboratory (30) or derived from vegetable sources (mainly from nuts, beans, and seeds), animal depot fats, fish, or marine mammals. Oils obtained from other sources differ markedly in their fatty acid distribution. Table 2 shows compositions for a wide variety of oils. One variation in composition is the chain length of the fatty acid. Butterfat, for example, has a fairly high concentration of short- and medium-chain saturated fatty acids. Oils derived from cuphea are also a rich source of capric acid which is considered to be medium in chain length (32). Palm kernel and coconut oils are known as lauric oils because of their high content of C-12 saturated fatty acid (lauric acid). Rapeseed oil, on the other hand, has a fairly high concentration of long-chain (C-20 and C-22) fatty acids. 

Fats and fatty oils). For the most part, oil is contained in the kernel or embryo of the seed, though it can also occur in the flesh of the ginkgo fmit and in the endosperm of coconut, palm, and pine nuts. Relative amounts of some fatty acids present in a few types of nuts are given in Table 5. Considerable variations in the percentages of fatty acids have also been reported in both pecan and peanut oils from a variety of sources. (Table 6). (For main physical characteristics and the composition of nut oils, see Fats and fatty oils. 

Nuts and Nut Products. Nuts are used mainly as edible products and marketed either with or without the shell, as the demand requites. The most popular nuts ia the shell are English walnut, filbert, almond, Brazil nut, peanut, pistachio, and the improved, or paper-shell, pecan the most popular salted and roasted nut kernels iaclude these as well as the cashew, macadamia, and pignofla. Each year more nuts are shelled ia ceatraHy located plants and marketed as meats. The annual per capita consumption of shelled tree nuts ia the United States rose from 0.78 kg in 1987 to 1.00 kg in 1992 (132). 

Although nuts have been a staple food in many countries for generations, their status in the United States as a chief food crop is relatively recent. The main suppher of Knglish walnuts, filberts, and almonds had been Europe. However, pecans and black walnuts are indigenous to North America, and the United States is the principal producer of pecans. Other U.S. nuts, such as beech, butternut, white walnut, American chestnut, chinquapins, hickory, picon, and northern California black walnut, are utilized mainly for local consumption. Chestnuts and chinquapins are susceptible to the chestnut blight fungus, Endothiaparasitica which has virtually destroyed the American chestnut (152). 

Coconut. In 1988, total coconut production was 36,802,000 t, of which 81% was produced in Asia, mainly in Indonesia and the Philippines (157). The coconut is essentiaUy a crop of the lowland tropics (157). On the average, five nuts are required to produce 1 kg of copra, the dried endosperm of the nut. Copra is further processed to obtain coconut oil and copra meal. To produce coconut milk, which is an emulsion of coconut oil and water, grated fresh coconut meat is mixed with hot water and pressed (157). Either poles having an attached sickle-shaped knife or monkeys (158) may be used for harvesting. 

The hydraulieally tensioned, radial-fit bolt (Figure 6-32) replaees the traditional turbine shaft eoupling bolt and is reusable. The main body of the bolt is threaded at eaeh end and has a slight taper on the eenter seetion, whieh engages with the similarly internally tapered sleeve and the two nuts. The bolt is taper-bored at eaeh end to aeeept the puller that is part of the hydraulie tensioning system. 

Zinc diffusion sherardisingY " is mainly used for protection of ferrous metals against atmospheric corrosion. It has, in some respects, properties related to other types of zinc coating such as galvanising, but owing to the small dimensional change involved, it is of particular value for the treatment of machined parts, bolts, nuts, etc. 

The thermo-gravimetric (TG) and differential thermo-gravimetric (DTG) curves of the gingko nut shell are shown in Fig. 2 where the moisture losses take place up to 200°C followed by the pyrolysis reaction. Then, the major weight loss due to the main degradation occurs at around 360°C. This zone is referred to as the active pyrolysis zone where the evolution of volatile compounds occurs during decomposition of the primary hemi-cellulose and cellulose [5]. 

Cardanol, a main component obtained by thermal treatment of cashew nut shell liquid (CNSL), is a phenol derivative having mainly the meta substituent of a C15 unsaturated hydrocarbon chain with one to three double bonds as the major. Since CNSL is nearly one-third of the total nut weight, a great amount of CNSL is obtained as byproducts from mechanical processes for the edible use of the cashew kernel. Only a small part of cardanol obtained in the production of cashew kernel is used in industrial fields, though it has various potential industrial utilizations such as resins, friction-lining materials, and surface coatings. Therefore, development of new applications for cardanol is very attractive. 

There are two main varieties of carbon (i) crystalline (e.g., graphite and diamond), and (ii) amorphous. The amorphous variety consists of carbon blacks and charcoals. Carbon blacks are nonporous fine particles of carbon produced by the combustion of gaseous or liquid carbonaceous material (e.g., natural gas, acetylene, oils, resins, tar, etc.) in a limited supply of air. Charcoals are produced by the carbonization of solid carbonaceous material such as coal, wood, nut shells, sugar, synthetic resins, etc. at about 600 °C in the absence of air. The products thus formed have a low porosity, but when activated by air, chlorine, or steam, a highly porous material is produced this porous product is called activated charcoal. Chemically speaking carbon blacks and charcoals are similar, the difference being only in physical aspects. Carbon blacks find use in the rubber industry and in ink manufacture. An important use of charcoals is as adsorbents. 

Many dyes that have no chemical affinity to fibrous substrates can be attached to such substrates by intermediary (go-between) substances known as mordants. These are either inorganic or organic substances that react chemically with the fibers as well as with the dyes and thus link the dyes to the fibers. Mordants are traditionally classified into two main classes, acid and metallic mordants. The acid mordants are organic substances that contain tannins (see Textbox 64) as for example, gall nuts and sumac. The metallic mordants are inorganic substances, mostly mineral oxides and salts that include metal atoms in their composition. Table 94 lists mordants of both these types, which have been used since antiquity. 

Proanthocyanidins (PAs), also known as condensed tannins, are oligomeric and polymeric flavan-3-ols. Procyanidins are the main PAs in foods however, prodelphinidins and propelargonidins have also been identified (Gu and others 2004). The main food sources of total PAs are cinnamon, 8084 mg/100 g FW, and sorghum, 3937 mg/100 g FW. Other important sources of PAs are beans, red wine, nuts, and chocolate, their content ranging between 180 and 300 mg/100 g FW. In fruits, berries and plums are the major sources, with 213.6 and 199.9 mg/100 g FW, respectively. Apples and grapes are intermediate sources of PAs (60 to 90 mg/100 g FW), and the content of PAs in other fruits is less than 40 mg/100 g FW. In the majority of vegetables PAs are not detected, but they can be found in small concentrations in Indian squash (14.8 mg/ 100 g FW) (Gu and others, 2004 US Department of Agriculture, 2004). 

Silver is a normal trace constituent of many organisms (Smith and Carson 1977). In terrestrial plants, silver concentrations are usually less than 1.0 mg/kg ash weight (equivalent to less than 0.1 mg/kg DW) and are higher in trees, shrubs, and other plants near regions of silver mining. Seeds, nuts, and fruits usually contain higher silver concentrations than other plant parts (USEPA 1980). Silver accumulations in marine algae (max. 14.1 mg/kg DW) are due mainly to adsorption rather than uptake bioconcentration factors of 13,000 to 66,000 are not uncommon (USPHS 1990 Ratte 1999). 

Paan (betel quid) with tobacco is commonly used. There are four main ingredients in paan betel leaf, areca nut, slaked lime, and catechu tobacco is usually also a component, especially for regular paan users. Sweeteners and flavorings can be added and are often regional. Paan masala is a commercial preparation that is dehydrated and so nonperishable. 

The main sources of these compounds are vegetable oils, unprocessed cereal grains, and nuts. The vitamin formulations that may be added to foods are o-a-tocopherol, OL-a-tocopherol, o-a-tocopheryl acetate, oL-a-tocopheryl acetate, and o-a-tocopheryl acid succinate [403],...
