Chemical Composition Of Raw And Cooked Walnut
Chapter one
ABSTRACT
The nutritional potential of walnut was assessed by analysing the proximate composition of conophonut, functional characteristics, and bulk density of walnut flour.
The results suggested that the proximate composition should be The mineral content of walnut flour revealed calcium (6.93 + 6.78), iron (2.87 + 2.80), and magnesium (3.74 + 3.52), and the functional characteristics suggested Bulk density (0.65 + 0.82); swelling index (2.14 + 3.50). Water-absorbing capacity (1.89 + 2.61) Solubility (1.52 +2.78)

1.0 Introduction
Nut crops like as walnuts (juglas Nigra) and pecans (carya illinoenosis) show potential in certain areas of Virginia. Growing and handling are specialised, and while marketing is hands-on, demand can be high.
For fresh high quality nuts used both for eating out of hand and for cooking purposes (Carlson Jones 1940), there are many distinct edible net species found and picked in the wild, including as hickory.
Chestnut (Juglan Cineralal) is another once abundant native nut, but due to chestnut Blight Diseases, it is now an uncommon found in the forests.
English walnut, also known as Carpathian Peisan Walnut (Juglans regia), almond (Prunus amygda cus), and nadnut (Corylus avellana) are important sources of activated and nut production, although they are limited to select adapted zones. California is the top producer of English walnuts and almonds, and Oregon producers produce 95% of all hazelnuts (more in 1977).
In the east, hazelnuts are also known as filberts, and numerous wild kinds have slumbly growing patterns. Eastern filbert nut production is unpredictable and heavily impacted by weather conditions in the winter.
Typically, blossoms (catkins) bloom in late winter to yearly spring, and while frost hardy, they can be harmed by harsh cold weather (Hamel, Dictoskey 1975).
Commercial southern pecan (also known as paper shell type) is the most important nut crop for the Eastern US, followed by wild-gathered native black walnuts. The pecan industry is centred in the south and south easts
with Creogia a leading state, and in the Southern plans, many acres are raised in Texas and Oklahoma, and even as far west as New Mexico (Harloro, Harrar, Harden white 1996).
Variety development for southern pecans has been extensive, and they are renowned for their large size and very thin shells; however, as a starting point, good site selection is imperative for success; one must have an understanding of the frost (Moerman 1998).
Native black walnuts can be found across the state, and there are several improved black walnut cultivars available through restricted breeding efforts and wild selection.
Overall, these strategies have focused on timber qualities (fester growth). The dual use capability of black walnut cultivars for lumber and high-quality net crop is an essential feature.
There are several outstanding black walnut varieties known for their nut qualities, including sparrow’s Emma Rupert “Hay” and Lawik corp; the latter is often used as a Purdue University has developed a lene of black walnut known for its faster growth for timber purposes as well as predictable nut bearing habits (Carlson Jones 1940).
The Northern pecan is a native of the Olio, Wabash, and upper Mississippi inver basins, and in recent years a number of remarkable selections have been developed from around the world, this Northern pecan is noted for its high-quality nut meats.
Houch has more oil content and better flavour than the southern kinds, although they have been much smaller units in comparison (Countryman et al 1985).
While Native (Southern) pecans are not as common in Nigeria as they are in the Midwest, they can be found in many parts of the states, including the middle and southern Premont regions.
Northern pecans are known for their cold hardiness, later flowering to avoid frost, and shorter nut maturation periods when compared to the southern pecan (Chenoweth 1995 black walnut). The Northern pecan selection has fair to good nut size (at best 50-60% of the southern pecan).
Furthermore, the grafting window is narrow, and the propagator must have the scion (top) wood of the selected variety ready when the sap begins to flow. Recently, some keger nurseries have expanded their propagation of northern pecan and black walnut, and select identified kinds are now available as poilted and pre-grafter attempts. (Fowles 1965). The goal of the experiment was to assess the chemical composition of walnut (C).
