Natural Bioactive Compounds from Winery By-Products as Health Promoters: A ReviewVIDEO ON THE TOPIC: Extracting Citric Acid from Lemons
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.

Even though aluminium is the most common metal on the planet, pure aluminium does not occur naturally. Aluminium atoms easily bind with other metals, forming compounds. At the same time it's impossible to isolate aluminium by simply melting down the compounds in a furnace, as is the case with iron, for example. The aluminium production process is much more complex and requires huge amounts of electricity. For this reason, aluminium smelters are always built in the vicinity of power energy sources, usually hydroelectric power plants that don't contaminate the environment.

Until recently, cheese processors and other dairies would discard whey by transporting it off-site to be dried by other companies, to drain into effluent treatment plants or city municipalities or to be used as cattle feed. But, when SPX Flow Technology introduced whey processing technology, which turns whey, lactose and permeate powders from a waste stream into a new source of profit, it opened new avenues for various applications and markets. The pediatric, geriatric, nutrition, ready-to-eat, baking, confectionery, health and pharmaceutical industries benefit from harvesting ingredients through this extraction process. Dairies identify the type of cheese production—sweet coagulation of cheese curd or acid coagulation. Then, depending on the raw material i. After crystallization, whey concentrate is then further dried in a spray dryer where each powder is treated depending on customer specifications. Recently, SPX Flow Technology received contracts to design and construct new plants that produce whey powder and non-caking permeate powder in Lithuania, and a high-yield lactose powder plant in France. After crystallization, whey concentrate is dried in a spray dryer, where each powder is treated depending on customer specifications.

Baking is a food cooking method that uses prolonged dry heat by convection, rather than by thermal radiation. Heat is gradually transferred "from the surface of cakes, cookies and breads to their centre. As heat travels through it transforms batters and dough into baked goods with a firm dry crust and a softer centre".

It will vary with the system followed, but whatever system may be practiced, the calf must receive the first milk which the cow gives after calving and is called colostrums. Be sure to feed the calf enough of colostrums between 2 to 2. Any excess colostrums may be fed to other calves in the herd in amounts equal to the amount of whole milk normally fed. If possible where a cow is milked before calving, freeze some of the colostrums for later feeding to the calf. None of it should be wasted. The digestibility of colostrums increases when it is given at a temperature between 99oF and oF. The importance of colostrums can be felt more from the following virtues.
