Peanut has different uses; you can have them as a snack or a meal. This feature of peanuts made companies make different products by using it. The introduction of peanut cultivation coincides with the spread of Mediterranean civilizations. Peanut is an important crop grown worldwide, originating in South America, and the peanut has spread throughout the Mediterranean, as well as China, Africa, India, Japan, and the United States. Most peanuts grown in the world are used to produce oil, peanut butter, candy, roasted peanuts and snack products, extensions in meat product formulations, soups, and desserts. Significant amounts of by-products are generated in the process of harvesting peanuts and extracting peanut oil, which are potential pollutants. However, only a few of these by-products are used as animal feed and treated as fertilizer. A large part of the groundnut meal, hulls, husks, and vines are considered agricultural waste. 
Currently, many researchers are focusing on the research on the production of edible oil and kernel. Thus, very little attention is paid to peanut by-products. In particular, no report was found that investigated the possibility of using peanut vines. These peanut by-products easily lead to environmental pollution. Therefore, if the nutritional compositions of peanut by-products are recovered and recycled, this can represent a significant economic and social benefit. The kernels are used to make peanut butter, roasted peanut snacks, peanut candies, and peanut oil. It is estimated that 35-45 g of peanut shell is generated per kg of a shelled peanut kernel. More than 0.74 million metric tons of peanut shells are produced annually worldwide as a byproduct of the peanut processing industry. Usually, only a small amount of peanut shell is used to extract polyphenolic compounds or to feed livestock, most of the shells are wasted in the peanut processing industry and are thrown away. It is well known that peanut shells contain powerful rich antioxidants. So, the more efficient use of peanut shells benefits the industry and the economy, and the use of peanut shells as a sustainable raw material for antioxidant compounds will provide environmental protection and improvement. While peanut shells can provide a cheap source of polyphenols for use as functional ingredients in food or food supplements and make a positive contribution to the nation's health. 
peanut products list
Peanut has different products which are used worldwide. We can name many products on the list. We just name some famous ones. Peanut oil has a pleasant, and sometimes light, nutty taste. In addition to its great taste, peanut oil is perfect for frying because it has a unique property. Therefore, you can cook several different items together and each will retain its excellent taste. Peanut oil is also one of the world's traditional frying oils because it can reach a high temperature that keeps the outside of the food crispy and the inside very moist. Peanut oil works well with all kinds of recipes and has been the frying oil of choice in many restaurants for years because it tastes great. Both refined and unrefined peanut oil are vegetable oils that are naturally trans fat-free, cholesterol free, and low in saturated fat. They are also a source of vitamin E, an antioxidant, and phytosterols, which benefit heart health and have been shown to protect against breast, colon, and prostate cancer. 
High oleic peanut oil is rich in unsaturated fats, especially monounsaturated fat, like olive oil. Because it can be heated to a higher temperature than other oils, resulting in less oil residue in food, refined peanut oil is the perfect choice for healthier frying. Peanut Flour is made from the highest quality peanuts that have been roasted and naturally processed to create a low-fat peanut flour with a strong roasted flavor. Peanut flour contains 40-50% protein, is gluten-free and vegan, and has even been shown to be good for heart health. Use of peanut flour Partially defatted peanut flour works well as a fat binder in confectionery as well as to add flavor and extend shelf life. It can also be used as an alternative to flour in gluten-free bread and pastries. Other ways to get creative with this unique ingredient include adding it to sauces and soups for texture and flavor, using it as a topping for chicken and seafood crumbles, and even mixing it into smoothies and shakes to increase flavor and protein content. 
use of peanut by-products
Nowadays there are different peanut by-products with different uses. You might not be surprised to find peanuts in birdseed—in fact, you can probably see them in the bag yourself and know to stay away. Likewise, peanut shells and hulls are also used to provide roughage with fiber in livestock feed, so people allergic to peanuts should be careful when dealing with feed used for livestock. But what about cosmetics? While you don't expect to find peanuts in your soap, shampoo, or body lotion, peanut-derived ingredients are not uncommon in those products. You can even find peanut shells in faux fireplace logs. In total, it found 23 non-food products that can be made with peanuts. Please note that not all of the following products will necessarily contain peanuts - in some cases peanuts are not currently used or have just been used in research projects. But this list should provide you with what you need to do your own analysis to protect yourself (or your peanut-allergic loved one). 
Peanuts themselves can be ingredients in: Like fat. George Washington Carver was the first to use peanuts for this purpose, although petroleum-based products are much more common these days. Bird seed. Pale. This only applies to colorless varieties of bleach, not chlorine-based bleach. Detergent. This is unusual, but it is possible to find peanuts in detergents. Explosives. Peanuts can be used to make explosive nitroglycerin. Ink. George Washington Carver also started this, but it is not found much in the modern world. Linoleum. This is another invention of George Washington Carver. Medicines. Always be sure to tell your pharmacist you are allergic to peanuts when filling your prescription, and be sure to buy over-the-counter medications. Metallic varnish. Peanuts seem to be the most common ingredient in homemade polishes. Pet food. Dogs love the taste of peanut butter and several common dog treats come in a peanut flavor. Color. This is a very unlikely (but possible) use for peanuts. Rubber. George Washington Carver experimented with this, but I could find no evidence that it was ever done commercially. 
peanut meal uses
Peanut meal is a by-product obtained after the extraction of oil from peanut (also called groundnut) seeds. Peanut meal has different uses and is the sixth most common oil meal ingredient produced worldwide after soybean meal, beet meal, sunflower meal, cottonseed meal, and palm kernel meal (USDA, 2016). Peanut meal is generally considered an excellent feed ingredient because of its high protein content, low fiber, high oil content, and a relative absence of anti-nutritional factors. It is often the standard source of high-protein foods in regions where soybean meal is too expensive or unavailable. However, aflatoxin contamination remains a serious problem, especially for peanut meals produced from seeds grown in small-scale systems. Peanut meal is produced only by mechanical extraction or mechanical followed by solvent extraction. It is also sold in the form of pellets. Expeller meal consists of light gray to brown pieces (flakes) of variable size with a smooth, slightly curved surface. The solvent-extracted meal consists of light gray to brown flakes of various sizes. Peanut meal pellets range from 1.5 to 40 mm in diameter and are light to dark gray. Peanuts come from South America. It was cultivated in Peru as early as 1500 BC, and probably earlier. The Incas used it for its seeds, which were eaten on toast, and its oil. After the arrival of Europeans in America, the peanut spread all over the world. In 1800, an oil mill was established in Spain, and West Africa became the primary source of peanut exports in the 19th century. Groundnut is now an important crop that is widely distributed throughout tropical, subtropical, and warm temperate areas in Asia, Africa, Oceania, North and South America, and Europe. In 2014, peanut cultivation covered 25.7 million ha worldwide, including 13.1 million ha in Africa (51%), 11.2 million ha in Asia (44%), and 1.3 million ha in America. 
industrial uses of groundnut
Groundnut a self-pollinated legume is an important crop grown worldwide on 24 million hectares for edible oil extraction and mostly for food use and sometimes industrial uses. The kernels are rich in oil (48-50%) and protein (25-28%) and are a source of various vitamins, minerals, antioxidants, biologically active polyphenols, flavonoids, and isoflavones. Improved high-yielding peanut varieties were developed and released for cultivation worldwide. The improved cultivars belong to different duration of maturity and possess disease resistance, drought tolerance, increased oil content, and improved quality properties for food use. Conventional breeding procedures along with phenotyping tools have been used extensively in groundnut improvement programs. Mutations were used to induce variability and extensive hybridization was attempted to exploit wild species variability. The enormous potential of wild species, the reservoir of new alleles, remains underutilized. The development of peanut linkage maps in the last decade has been followed by the identification of markers and quantitative trait loci for target traits. 
Consequently, the last decade has witnessed the deployment of molecular breeding approaches to complement ongoing groundnut improvement programs in the USA, China, India, and Japan. Other potential advantages of molecular breeding are the feasibility of targeting multiple traits for improvement and providing tools to exploit new alleles from wild species. The first peanut variety developed by marker-assisted backcrossing is a root-knot nematode-resistant variety, in the United States. Adoption of molecular breeding approaches in groundnut improvement programs by NARS partners in India and many African countries have been slow or has to be initiated in part due to inadequate infrastructure, high genotyping costs, and human capacity. The availability of draft genome sequence for diploid (AA and BB) and tetraploid, AABB genomic species of Arachis in the coming years is expected to bring low-cost genotyping to the peanut community enabling the use of modern genetics and breeding approach will facilitate, such as genome association studies for trait mapping and genomic selection for crop improvement. 
peanut meal for sale
Peanut meal is the product that remains after extracting the oil from peanuts. In some foreign countries, it is called a peanut meal. The expeller-treated peanut meal contains about 5% fat. The fats in peanut flour are unsaturated and can easily develop granulation. It is best to use solvent-extracted peanut flour, which contains about 2.1% fat. If peanut meal is used for horses, it should be fed fresh and only stored for short periods in a cool, well-ventilated area. Because of the possibility of scaling and the low level of lysine and methionine, peanut meals should not be fed to valuable foals or young fast-growing horses. It is best used with about a quarter to a third of the protein supplement added to the concentrate diet for older horses. Peanut meal is a very tasty protein supplement. Peanut meal contains complex carbohydrates, and the extracted peanut polysaccharides have a high starch content, which greatly reduces the purity of the polysaccharides and limits their physiological activity. Therefore, starch removal of polysaccharides from peanut flour is an important step in the purification of peanut polysaccharides. It is better to use the thermostable α-amylase and diastatic enzyme of polysaccharide peanut meal to remove starch. Nutmeal is a high protein solid residue obtained from oil production. The amount of flour produced each year is quantified at approximately 3.3 million tons. 
In addition to proteins, the meal also contains carbohydrates, which enrich the nutritional value of this by-product and make it a valid alternative to meat. Minor components found in the meal are polyphenols and minerals. As already mentioned, peanut flour is a waste product of the oil industry: after extracting the oil, a cake is obtained which is generally divided into a dry and fresh, hot and cold meal. Peanut protein represents an interesting and valuable alternative to animal protein, especially in developing countries where meat is unavailable and expensive. The Protein Corrected Digestibility Score (PDCAAS) defines peanut protein as nutritionally equivalent to meat and eggs. Such proteins also show good technological properties and are promising enhancers in food formulations. Besides protein, polysaccharides are other important meal components, although they seem to reduce the digestibility of protein.
