The dietary caliber of a protein relies on the percentage of its amino acids-especially the basic amino acids-their physio­ logical availability, and the explicit necessities of the shopper. Availability varies and relies on protein resource, interplay with different nutritional elements, and the consumer's age and physiological country. in lots of meals, specially these from vegetation, low degrees of varied crucial amino acids limits their nutritive worth. this is often fairly very important for cereals (which could be insufficient within the crucial amino acids isoleucine, lysine, threonine, and tryto­ phan) and legumes (which are frequently terrible resources of methionine). furthermore, those commodities are precept assets of protein for a lot of the earth's swiftly becoming inhabitants. on the present annual development cost of approximately 2 percentage, the area inhabitants of approximately four billion increases to 6.5 billion through the 12 months 2000 and to 17 billion by way of the 12 months 2050. milliQn everyone is almost immediately anticipated to undergo protein malnutrition, with approximately fifteen thousand day-by-day deaths. The ratio of malnourished to effectively nourished will nearly definitely elevate. For those purposes, and particularly in view of the restricted availability of top quality (largely animal) protein to feed current and destiny populations, development of meals and feed caliber is principally important.

Unfortunately, only limited research has been carried out on the rheological characteristics of the corn dough itself, mainly because -at least in some countriestortilla preparation is a homemade process with only a very small contribution from the industry. Nevertheless, it is expected that as industrialization progresses, convenient corn-based products will have their place in the market of corn-eating countries, and those properties have to be studied. Table 10 summarizes the effect of adding soybean flour, with different nitrogen solubility, to lime-treated corn.

Table 11. ' o IMPROVEMENT OF PROTEIN QUALITY OF CORN 51 as compared to the corn dough alone. Again, the cornwhole soybean sample took a longer time to reach maximum stiffness. In summary, these findings show that the addition of soybean flour tends to decrease the breakdown resistance of the corn dough, probably due to the reduction of starch contained in these mixtures that was replaced by soy proteins. It is known that soy globulins do not possess the same rheological properties as cereal proteins.

And also to the fact that Fortesan was formulated in accordance with the dietary habits and beliefs of Chilean mothers.
