ABSTRACT

Different blanching methods were adapted to remove oxalates from frozen spinach. Blanching by steam, boiling water, 2% boiling citric acid solution, 2% boiling Mg citrate solution, and by boiling water before the addition of 0.5gm. Mg citrate/500gm. Spinach before packing; were investigated. Frozen spinach prepared by these blanching methods was analyzed and compared for total solids, total soluble solids, pH value, vitamin C, chlorophyll retention%, carotenoids, oxalates, minerals and ash. Organoleptic evaluation of the final products; statistically analyzed, showed that the best treatment was that of the combined effect of water blanching and the insertion of 0.5gm. Mg citrate in each 0.5 kilogram pouch of frozen spinach

ABSTRACT

Absorption rate of biphenyl was determined in used pads, whole orange fruit, peel and juice stored under different conditions of ventilation, temperature and storage period. It was found that the rate of biphenyl a bsorption complied with the maximum permitted level of biphenyl in the United States and in most of the European Countries if packed in vented cartons as it is usually done commercially. However, with non-vented cartons, the absorption rate increased above the upper level of the a bsorbed biphenyl permitted by both Germany and France, when stored at 60F. Generally the non-vented cartons efficiently decreased the rate of orange decay compared with vented ones

ABSTRACT

The influence of various factors on the production of lactic acid using enriched beet molasses by Lactobacillus delbrueckii was investigated. The best yield was 62.6% while the conversion coefficient was 80.7 at 45C. Also, the highest yield and conversion coefficient obtained 81.4% and 58.7% respectively when using 12.62% sugars. Consequently, the best concentration could be around 18% total soluble solids. Optimum pH seemed to be around 6 since both yield and conversion percent was the highest. The optimum fermentation period, however; could be considered on the 8[th] day of fermentation, when maximum yield and conversion coefficient were obtained

ABSTRACT

Patti Beans of different blends containing distinct pulses, [i.e., broad beans, soybeans, and chick-peas, whole egg and some green herbs] were evaluated for their protein content, ether extract, ash, starch, fiders, calcium, and phosphorus content. However; emphasis were given to their amino acids content revealing that after frying the best blends were those consisting of 70% broad beans, and 30% soybeans [blend No. 40], 80% broad beans, 10% soybeans, and 10% chick-peas [blend No. 10], and 80% broad beans and 20% soybeans [blend No. 6], since the proportion of the sulphur amino acids, which could be considered a limiting factor, were 2.840, 2.653 and 2.631 respectively. The frying process however; seemed to destroy the available amino acids to an extent of 16.510%, 6.550%, and 6.199%, for tryptophan, lysine, and cystine; respectively. The destruction of other amino acids ranged from 0.732% to 4.204%. The addition of egg did not increase the amino acids contents, but it improved the flavour of the product. The best blend which had the highest flavour scores was No.10

ABSTRACT

The Bisara is usually made of dehulled broad beans [Vicia faba, Linen] mixed with green herds and spices. However, its content of protein is low both in quality or quantity. Blending such ingredients with soybeons and/or%ckpeas resulted in raising the proportion of methonine and cystine to almost the value suggested by the F.A.O. The addition of milk solids, however, plus the prementioned in gredients resulted in improving such proportion of sulphuramino acids as well as producing a better flavour. On the other hand, the N.P.U. values were in line with improving values of sulphur-containing amino acid proportion. The best blend, however, was that which contained 70% dehulled dry broad bean, 10% soybeans, 4.5% check peas, 5% onion, 1% garlic 9% green herbes, and 0.5% dried yeast [blend No.5]

ABSTRACT

Different recipes of dried lentil soup were prepared in various blends. The ingredients that incorporated were dried dehulled cracked lentil dried soybeen seeds, dried%ck-peas seeds, fresh carrots, fresh tomato, and fresh onion. The former blends ingredients were cooked under pressure, then strained and dried in open oven at 70C. The dried blends were milled and sieved to reach a 95% extraction ratio. Then the resulted powder were mixed to other dry ingredients to form different blends. Such blends however, were able to raise the nutritional values without impairing the organoleptic properties. Protein was raised quantitatively and adapted qualitatively to meat the F.O.A. pattern. Best blend was that [No.6], which included lentil, soybean,%ck-peas, carrot, tomato, onion, and dried whole egg

ABSTRACT

The extracted nitrogen was performed and evaluated at different pH values. The protein isolates, however; were prepared from soybeans, broad beans, white bean, peas, and peanut. The physical properties, such as the degree of protein solubility at different pH values were studied and discussed. In addition the protein isolates were tested mainly for their amino acid profile as well as for their characteristic chemical components. It was detected however; that such protein isolates were deficient in the sulfer amino acids, methionine plus cystine, a matter that limited their nutritive value as was confirmed by the biological study done on experimental rats
