Product commercial protein products
Nick Bajjalieh, Ph. President, Integrative Nutrition, Inc. The animal production industry provides for one of the most basic of human needs, quality food proteins. It does so through a synergistic relationship with other segments of agriculture. One such segment is that devoted to oilseed production and processing. Through this relationship, both segments complement, and to a certain extent enable, the economic sustainability of one another.VIDEO ON THE TOPIC: SNL Commercial Parodies: Tech

Protein Powder Manufacturing
Edible soybean protein concentrates are relatively new products. Their availability as commercial products dates from In the last 30 years or so, these versatile products have become important ingredients, well accepted by many food industries. In many applications, they simply replace soy flours.
In others, they have specific functions which cannot be performed by soy flours. Historically,the need for the development of soybean protein concentrates stemmed primarily from two considerations: to increase protein concentration and to improve flavour.
It is very difficult to avoid the occurrence of the green-beany flavour of soybeans in untoasted full-fat or defatted soy flour, prepared in the conventional way. Beany flavour is one of the major objectionable characteristics, limiting the use of conventional soy flours. One of the objectives of the further processing of flours into concentrates is to extract the particular components which are responsible for the bitterness and beany taste.
In certain applications, such as in meat products, a soybean protein ingredient with a higher percentage of protein is often preferable. Soybean protein concentrates normally cost 2 to 2. The starting material for the production of soy protein concentrates is dehulled, defatted soybean meal with high protein solubility white flakes. The concentration of protein is increased by removing most of the soluble non-protein constituents.
These constituents are primarily soluble carbohydrates mono, di and oligosaccharides , but also some low molecular weight nitrogenous substances and minerals. Normally, kilograms of soybean protein concentrate are obtained from one metric ton of defatted soybean flakes.
There are three major methods for extracting these components in a selective manner, without solubilizing the major protein fractions. These are not different methods for manufacturing the same product, but each method produces a different type of concentrate, with distinct characteristics and specific uses.
These methods are known as:. AAFCO , specifies soy protein concentrates as follows:. Protein mfb. Crude fibre 4. Negative E. Coli in 1 g Negative As explained above, there are three basic types of soy protein concentrates, distinguished according to the method used for extraction of the non-protein solubles.
All three types have basically the following proximate composition, on a moisture-free basis:. Soy protein concentrates are further characterized by their protein solubility index. Soy proteins are rendered insoluble by each of the three extraction processes.
However,it is possible to increase the solubility of the protein in the concentrate by further processing, for example by neutralization of acid washed concentrate with alkali. The molecular changes in the proteins caused by alcohols are, however, different from those resulting from heat denaturation. Thus, alcohol-wash concentrate retains most of the functional properties slurry viscosity, emulsification power etc.
The dispersibility and functionality of alcohol-wash concentrates can be increased by steam injection or jet-cooking, and improved further by high-shear homogenization. Soy Protein Council Much of the characteristic beany flavour is also usually removed by the extraction process.
Soybean protein concentrates are relatively bland. The flatus-producing oligosaccharides of soybean flour,raffinose and stachyose, are also efficiently removed by the solvents used in the production of concentrates.
Soy protein concentrates are marketed in various forms: granular , flour and spray dried. In addition, texturized concentrates are also available. These texturized products will be discussed in a separate chapter. Since some low molecular weight proteins are also extracted along with the sugars, the amino acid composition of the concentrates may differ slightly from that of the original flour.
Table The process is based on the ability of aqueous solutions of lower aliphatic alcohols methanol, ethanol and isopropyl alcohol to extract the soluble sugar fraction of defatted soy flour without solubilizing its proteins. The theory of solvent extraction see para. Starting with defatted white flakes as raw material, the process consists of the following steps: Liquid-solid extraction, removal and recovery of the solvent from the liquid extract, removal and recovery of the solvent from the extracted flakes, drying and grinding of the flakes.
Continuous extraction is justified for relatively large scale operations. According to Campbell et al. Unlike oilseed crushing industries, smaller plants are not uncommon in this branch. The batch process is, therefore, rather widely applied. The methods and types of equipment used are essentially similar to those encountered in oil extraction plants: horizontal belt and basket extractors, stationary and rotary cell extractors etc. In the case of alcohol extraction, the solvents are quite volatile and flammable.
Adequate precautions for the prevention of fire and explosion are necessary. The reason for using high-NSI white flakes as the starting material is not necessarily related to the objective of obtaining a product with high protein solubility.
As explained above, this would not help anyhow , due to the different type of protein denaturation caused by the alcohol. The principal reason for preferring this type of raw material is due to the fact that the percentage of extractable soluble sugars in white flakes is higher than in toasted meal.
Toasting renders the sugars less soluble by binding them to proteins Maillard reaction or by caramelization. As a result of this type of condensation reactions, the sugars are no longer extractable by the solvent and they remain in the product, lowering the protein concentration in it. Furthermore, the darker colour of concentrates made from overheated meal is also objectionable, and their nutritional value is lower lower lysine availability.
They are then brought to the proper concentration and recycled through the extractor. The distillation residue is an aqueous solution of the sugars and other solubles. It is concentrated to the consistency of honey and sold as " soy molasses". It is mainly used as a caloric ingredient and as a binding agent in animal feeds.
The methods are essentially the same as for the removal of hexane from soybean meal flakes. Flash desolventizing, using superheated vapours of the alcohol-water mixture can be applied to protein concentrates.
Any excess water left in the flakes after desolventizing is removed by hot air drying. This process is based on the pH-dependence of the solubility of soybean proteins,discussed in Section It will be recalled that the majority of soybean proteins exhibit minimum solubility at pH 4.
Therefore, it is possible to extract the sugars, without solubilizing the majority of the proteins, using, as a solvent, water to which an acid has been added so as to keep the pH at the isoelectric region. The acid-wash process has the obvious advantage of using a non-flammable, non-explosive, non-toxic and inexpensive solvent: water. To a certain extent, this is also the disadvantage of the process. Separation of the solid from the solvent is more difficult and less complete, due to the fact that the flakes absorb considerable quantities of water and swell.
Gravity draining is not suitable for efficient solid-extract separation. Rotary vacuum filters or decanting centrifuges must be used instead.
A batch process using horizontal decanting centrifuges is shown in Fig. Defatted soy flakes or flour are mixed with acidified water in an agitated vessel. The slurry is then fed to the decanter centrifuge which separates the extracted solids from the extract whey.
The solids can be dried at this stage, to yield an "isoelectric" concentrate of low protein solubility. If a more functionally active, neutral concentrate is desired, the isoelectric solid cake is resuspended in water and the acidity is neutralized. The cake is usually wet-milled to a fine slurry and spray dried. The liquid extract containing sugars ,minerals, the protein fractions which are soluble at pH 4. Unlike cheese whey, however, soy whey has no use and must be discarded as waste.
The reasons for not using soy whey for animal feeding will be discussed in the next chapter, dealing with isolated soybean protein. In this process, the proteins of defatted soy meal are first rendered insoluble by thermal denaturation, using humid heat. The heat-treated meal is extracted with hot water, which dissolves the sugars.
Since the process is based on solid-liquid extraction using water as the solvent, the operations and equipment systems are essentially similar to those used in the acid-wash process, discussed in the previous paragraph. Just as with soy flours, soy protein concentrates are used in food products for their nutritional characteristics or for their functional properties or for both.
Nutritionally, the attractive features of concentrates include: their high protein content, the near-absence of anti-tryptic and other anti-nutritional factors, the absence of flatulence and the substantial "dietary fibre" content. The nutritional value of the protein in the concentrates of different types, expressed as Protein Efficiency Ratio PER is slightly lower than that of soy flour protein.
This is probably due to the slight fractionation effect of the extraction process, mentioned above. The most important functional characteristics of soy protein concentrates are: water binding water adsorption capacity, fat binding capacity and emulsification properties. Unless higher protein fortification levels are necessary, there is no special reason for using soy protein concentrates in bakery products.
Nutritionally and functionally, soy flours do the same job, more economically. This area probably represents the most important application of soy protein concentrates in the food industry. SCP is used mostly in comminuted meat, poultry and fish products patties, emulsion type sausages, fish sticks etc. The nutritional contribution of soy protein in low-meat, high-fat, low-cost products may also be significant. Campbell et al. Soybean protein concentrates have been used as stabilized dispersions in milk-like beverages and simulated dairy products such as sour cream analog.

Commercial Plant-Produced Recombinant Protein Products
Attention has recently turned to using plants as hosts for the production of commercially important proteins. The twelve case studies in this volume present successful strategies for using plants to produce industrial and pharmaceutical proteins and vaccine antigens. They examine in detail projects that have commercial potential or products that have already been commercialized, illustrating the advantages that plants offer over bacterial, fungal or animal cell-culture hosts. There are many indications that plant protein production marks the beginning of a new paradigm for the commercial production of proteins that, over the next decade, will expand dramatically.

Ronald J. The use of dietary supplements is widespread in the general population, in athletes and recreational exercisers, and in military personnel. A wide array of supplements is available, but protein-containing products are consistently among the most popular, especially among those who engage in resistance training. There are significant risks associated with the use of unregulated dietary supplements. Risks include the absence of active ingredients, the presence of harmful substances including microbiological agents and foreign objects , the presence of toxic agents, and the presence of potentially dangerous prescription-only pharmaceuticals. There is ample evidence of athletes who have failed doping tests because of the use of dietary supplements. There is also growing evidence of risks to health and of serious adverse events, including a small number of fatalities, as a result of supplement use.

Most colorimetric protein assay methods can be divided into two groups based on the type of chemistry involved: those involving protein-copper chelation with secondary detection of the reduced copper and those based on protein-dye binding with direct detection of the color change associated with the bound dye. Most commercial protein assay reagents are well-characterized, robust products that provide consistent, reliable results. Nevertheless, each assay reagent has its limitations; having a basic understanding of the chemistries involved with each type of assay is essential for selecting an appropriate method for a given sample and for correctly evaluating results. Biuret, a product of excess urea and heat, reacts with copper to form a light blue tetradentate complex.
Здесь она снова замерла. Все выглядело совсем не так, как несколько минут. ТРАНСТЕКСТ выступал серым силуэтом в слабом сумеречном свете, проникавшем сквозь купол потолка. Все лампы наверху погасли.
В одно мгновение в шифровалке установилась полная тишина. Сирены захлебнулись, мониторы Третьего узла погасли. Тело Грега Хейла растворилось в темноте, и Сьюзан, инстинктивно поджав ноги, прикрылась пиджаком Стратмора. В шифровалке никогда еще не было так тихо, здесь всегда слышался гул генераторов.
Теперь все умолкло, так что можно было различить облегченный вздох раненого чудовища - ТРАНСТЕКСТА, постепенно стихающее шипение и посвистывание, сопутствующие медленному охлаждению.
Все это было лишено всякого смысла. - Сьюзан, ты должна мне помочь. Стратмор убил Чатрукьяна.
