    Notes: Several established methods of phytic acid determination in soybeans were evaluated. Iron analysis methods, which rely on a 4:6 molar ratio of Fe:P, were eliminated because this ratio was not dependable. Three assay methods relying on phosphorus analysis were then compared. The anion-exchange method was considered most accurate but not convenient for routine analysis. Analysis of the ferric phytate precipitate and a new method, analysis of the supernatant before and after ferric chloride precipitation, were judged against the anion-exchange method under different extraction conditions. Based upon good agreement with anion-exchange column results and acceptable reproducibility, the best methods were (1) precipitate analysis of phosphorus after extraction with 3% TCA + 10% sodium sulfate, or (2) the supernatant difference method after extraction with 1.2% HCl.

    Notes: Full-fat soy (S), and other full-fat soy-whole egg (SE), soy-egg yolk (SEY) and soy-egg white (SEW) flours were produced and utilized as 12% supplements for patent wheat flour in breads. Addition of 0.5% sodium stearoyl-2-lactylate (SSL) improved loaf volumes of all bread types except SEY. Generally, 30 or 45 ppm bromate supplementation also resulted in increased loaf volumes. Organoleptic evaluations of bread types indicate that 100% wheat flour and SEY supplemented loaves scored well in most quality characteristics. Protein efficiency ratio analyses showed that all S and soy-egg fortified breads produced better growth than 100% wheat flour bread. The results indicate that supplementation of breads with SEY flour produces breads of good quality without the need for SSL or bromate.

    Notes: Procedures for the preparation of 100% winged bean or mixed winged bean-soybean curd employing the essential steps of soy curd production have been developed and optimized. Use of magnesium chloride, gluconodelta lactone, acetic acid and calcium sulfate as coagulants was investigated. The results showed that while curd formation was not facilitated by acetic acid, sticky and less cohesive curds could be formed with magnesium chloride and gluconodelta lactone. Calcium sulfate precipitation resulted in a semi-solid and appreciably cohesive curd from winged bean. Winged bean curd had very low hardness value in comparison to soy tofu. Curd products prepared from five ratios of winged bean-soybean mixtures indicate that 50:50 and 25:75 winged bean-soybean combinations by weight resulted in satisfactory products.

    Notes: The influence of soy product processing on whole-body 59Fe retention by the rat was examined. Some, but not all, soy protein products present in the diet previous to a casein-based radiolabeled test meal lowered iron retention relative to that by rats fed the casein diet. A soy fiber preparation in the diet did not adversely affect 59Fe retention. When various radiolabeled test meals were fed in either acid or neutralized form, neutralization of soy protein isolate (SPI), but not of casein, led to less 59Fe retention (PC 0.01) from the test meal. After appropriate heat treatment, 59Fe retention from acid and neutralized SPI was not distinguishable.

    Notes: Calcium bioavailability (BV) from sesame seeds, almond powder, whole wheat bread, spinach, and nonfat dry milk (NFDM) was compared to calcium BV from a calcium carbonate (CaCO3)-supplemented control diet using a rat model. When comparing different calcium sources, the relative BV of the products was CaCO3 (100%), NFDM (100%) whole wheat bread (95%), almond powder (66%), sesame seeds (65%), NFDM and spinach mixture (52%), and spinach (47%). Separate almond, NFDM, and CaCO3 diets were supplemented with 0.4% ascorbic acid; vitamin C addition had no significant effect on calcium BV.

    Notes: Various ratios of potato:full-fat soy:whole egg (P:S:E) were combined and drum dried to yield flakes which were rehydrated and formed into baked or fried patties. Methods were developed to utilize either fresh or dehydrated potatoes for flake production. Sensory evaluations showed 60:34:6 P:S:E fried patties to be more generally accepted than baked patties. Freezing of the uncooked dough prior to frying or baking was shown to be a good storage method. P:S:E flakes (60:34:6) were also substituted for 12% of patent wheat flour in bread. P:S:E supplementation improved the protein efficiency ratio (PER) of patent flour wheat bread. PER's for 60:34:6 P:S:E flakes and baked patties were equivalent to casein.

    Notes: Soy beverage was prepared with a tap water or 0.25% sodium bicarbonate blanch. Retentions of vitamins B1, B6, niacin, pantothenic acid, folacin and the amino acids lysine, methionine and tryptophan were determined from samples taken after various process steps. The results indicate that bicarbonate blanch reduces the retention of most of the B vitamins but slightly increases the retention of tryptophan in the soy beverage. More than 50% of niacin, pantothenic acid and vitamin B6 was lost in the blanch water, irrespective of treatment. Reuse of blanch water in latter stages of the soy beverage process could result in 95% or more recovery of all measured nutrients, with the exception of thiamine.
