Soybeans have a high protein content. In most legumes , protein accounts for 20% to 30% of the weight. In  wholes soybeans, protein accounts for 40% of the weight.

Soy foods are a source of high quality lean protein. In addition, consumption of soy protein provides health  benefits that may help prevent certain   chronic diseases. The amount of protein varies in soy products, with the following products generally containing these percentage, soy flour, 50%, soy concentrate 70%, and soy isolate, 90%.

The amino acid profile of soybeans compares well with the human requirements. The World Health  Organisation has established that when consumed at the  recommended level of protein intake, soy protein contains sufficient amounts of all essential amino acids human needs.

Evaluating Protein Quality

Different methods of estimating protein quality have been used at different times. However the following three are the most common and accepted.

Biological value (BV) , it is a measure of the amount of protein retained by the body.
Protein Efficiency Ratio (PER ), It is the measure of growth following intake of a certain protein.
Protein Digestibility Corrected Amino Acid Source (PDCAAS): It measure the amount & percentage digestibility of each amino acid.

PDCAAS  system as determined by the WHO , now supersedes both PER and BV methods and is accepted as the official method by USFDA. Isolated Soy Protein ( or Soy protein Isolate) source the maximum 1  point on this system

PDCAAS of Selected Food protein

Highlights of Soy Protein.


1.      Soy Protein is the only protein classified as a complete protein.
2.      Foods containing soy protein are known to provide the potential benefits of dietary factors in preventing chronic disease.
3.      Soy is high in Calcium and unlike milk does not contain ‘casein’ proteins that result in calcium loss in bones.
4.      Soy does not have cholesterol


“ Diets low in saturated fat and cholesterol that include 25gms of soy protein a day may reduce the risk of heart disease.”—U.S.F.D.A

What is Modem and Fax Modem: A modem enables your computer your computer to receive/send data from/to remote places through telephone lines, to the other computer provided each has a compatible modem. These are attached to serial port of the computer. Modems are used to connect a computer to a remote network through dial-up or leased line connections. A modem is controlled by using a communication program. Some of the On-line services, one can avail through a modem, are: “Electronics mail” “Banking and travel reservations” “File transfers” “Fax Services” “Internet access” Modem of varying speeds, measurable in Megabits per second (Mbps), are available in the market. Some of the common speeds are 14.4 Mbps, 28.8 Mbps, 33.7 Mbps and 56.4 Mbps. Fax: In the present day computer system, FAX machines can be attached with A COMPUTER IS SEND AND RECEIVE DOCUMENTS CREATED IN THE COMPUTER TO DISTANT PLACES, BRINGING COMPUTERS AND COMMUNICATION toget...
