Book Description
Cotton is the basic resource for thousands of consumer and industrial products manufactured in the world. Cotton seed meal (CSM) is a byproduct of the oil industry, and a source of high protein content, fiber and phosphorus. Cottonseed contains about 22.5% protein; this represents about 9.4 million tons of protein human consumption. Cottonseed meal is used for feeding cattle because of its high oil and protein content. After oil extraction cotton seed meal can have up to 55% protein; however, the presence of free gossypol may be responsible for poisoning in animals such as respiratory pain, anorexia, weakness, and death. Gossypol is found in the cotton plant and it is concentrated on cottonseed. There is currently a variety of Glandless Cotton Seed that contains a low amount of gossypol and can be processed into different food products for human consumption. The ability of glandless cottonseed meal to be processed into different foods is largely determined by the proteins that show the complexity and different interactions with each other. The objective of this research was to characterize the protein based on molecular weight, solubility, thermal stability and amino acid content. The deferent protein fractions in glandless cotton seed meal (GCSM) were extracted with a different solvent. The molecular weight of the different fraction was determined with SDS-PAGE. The GCSM protein had an isoelectric point of 5.1. No proteins were extracted with alcohol or acid solution. Most of the protein were extracted with 0.1 N salt solution and 0.1 N KOH solution. The glutenin fraction showed bands between 44 and 66 kDa and a denaturation temperature (Td) between 52.1 -- 71.7°C. The albumins had a molecular weight of 20 -- 29 kDa and a td between 50 -- 73.4°C. The globulins showed bands between 14 -- 20 kDa and a Td value of 53.6 -- 74.8°C. With this research, we can say that glandless cottonseed meal protein is as important as the most known proteins. Since glandless cottonseed meal contains similar values in fiber, minerals, amino acid and protein compared to soybean meal protein, whey protein, peanut meal protein and linseed protein we can use it as substitute or complement in the human diet.

Book Description
Current growth in global aquaculture is paralleled by an equally significant increase in companies involved in aquafeed manufacture. Latest information has identified over 1,200 such companies, not including those organizations in production of a variety of other materials, i. e. , vitamins, minerals, and therapeutics, all used in varying degrees in proper feed formulation. Aquaculture industries raising particular economically valued species, i. e. , penaeid shrimps and salmonids, are making major demands on feed ingredients, while relatively new industries, such as til apia farming, portent a significant acceleration in demand for properly formulated aquafeeds by the end of the present decade and into the next century. As requirements for aquafeeds increases, shortages are anticipated in various ingredients, especially widely used proteinaceous resources such as fish meal. A variety of other proteinaceous commodities are being considered as partial or complete replacement for fish meal, especially use of plant protein sources such as soybean meal. In the past five years, vegetable protein meal production has increased 10% while fish meal production has dropped over 50%, since 1989, largely attributed to overfishing and serious decline in wild stock. Throughout fisheries processing industries, traditional concepts as "waste" have given way to more prudent approaches, emphasizing total by-product recovery. Feed costs are a major consideration in aquaculture where in some groups, i. e. , salmonids, high protein-containing feeds using quality fish meal, can account for as much as 40 to 60% of production costs.

Book Description
The world supply of protein is derived from either plant or animal sources. Plants provide 65% of total amount in global protein production and animal products contribute 35% of per capita availability of food protein. In the food industry, proteins from seeds possess desirable functional properties and provide essential amino acids in food systems. The seeds most frequently used are soybean, pea, sunflower and some cereals, due to their nutritional value and their functional properties, such as emulsification, solubility, foaming properties, and water and oil absorption capacities. New protein sources from seeds have been reported as potential ingredients in certain food applications and promise new alternatives in the food industry. Cottonseed meal is by-product after lint fiber is ginned. Once seeds are separated from hull plant, these are crushed and the oil is extracted. Cottonseed meal is mainly used to feed animals in the countries where cotton oil is produced. However, the cottonseed meal can be fed only to adult animal ruminants because it contains a compound called gossypol. Gossypol is highly toxic to monogastrics because affects enzymatic reactions for many biological processes, as well the ability of cells to respond to oxidative stress and inhibition of oxygen from hemoglobin. Gossypol is found in the cotton plant and it is concentrated in the seed. A natural cotton selection with low gossypol content was used in this research. The objectives of this study were determined pH and temperature effect on glandless cottonseed protein extraction. Glandless cottonseed protein for human consumption is possible to several factors including abundance, desirable texture, and good nutritional properties in food. Finally, to optimize a protein extraction process from glandless cottonseed meal would have potential applications in food industry: this could improve quality in foods and developed new products.
