Chemical composition, minerals content, amino acids, fiber fractions, fatty acids profile, total phenols, total flavonoids and antioxidant activity were determined in wheat flour (WF) 72%, moringa leaves powder (MLP), defatted moringa seeds powder (DMSP) and moringa seeds (MS). Pasting profile and rheological properties of blends supplemented with MLP at levels of 3, 6, 9 and 12% or DMSP at levels of 5, 10, 15 and 20% were also studied. The highest moisture and carbohydrate contents were found in WF (12.60 and 85.05%), respectively. MLP had higher ash and fiber contents (8.87 and 7.91%), respectively, while, protein and fat contents were higher in DMSP and in MS. Mineral content (Ca, K, Mg, P, Na and Fe) in MLP was the highest, while DMSP was higher in Zn content than that of other samples. Fiber fractions of WF were lower than that of both MLP and DMSP. Total essential amino acids of DMSP was higher (19.25%) than that of MLP and WF (12.45 and 4.16%), respectively. Oleic acid was the predominant fatty acid (66.85%) in moringa seeds oil. MLP had the highest value of total phenolic, total flavonoid and antioxidant activity (11.97, 8.02 and 15.87 mg/g), respectively. Color measurements showed that all of MLP, DMSP and WF blends decreased in L*, a*,however, they increased in b*, saturation, hue and ∆E values. Supplementation with MLP and DMSP at all levels decreased the peak viscosity, trough, breakdown, final and setback viscosities. While, it increased water absorption, dough development time, mixing tolerance index and dough weakening. On contrary, arrival time and dough stability were decreased. Also, MLP and DMSP decreased the extensibility, resistance to extension, maximum resistance to extension energy of dough and the proportional number.

The evaluate some safety treatments including: mulching, tunnels, natural yeast extract, antioxidant and two rhizobacteria Serratia marcescens and Pseudomonas fluorescens towards root-knot nematode Meloidogyne spp. on strawberry plant grown in naturally infested soil and consequently their probable effects on growth parameters, chemical components and yield of strawberry compared to untreated control. Results of this study confirmed that all used treatments, significantly reduced all related nematode parameters i.e. number of galls/root system; number of egg masses/root system as well as number of juveniles/250 g soil (either after 2 or 4 months) when compared to plants grown in the naturally infested soil only. The highest percentage of reduction in all related nematode parameters were noticed after 4 months. Mulching, S. marcescens, P. fluorescens and tunnels, played an important role in reducing the percentage of nematode parameters. Mulching and S. marcescens reduced the percentage of gall numbers/root system by 77%, followed by tunnels by 75% and P. fluorescens by 70%. S. marcescens reduced the percentage of egg masses/root system by 80% followed by P. fluorescens by 78% and mulching by 76%. Results indicated that the soil treated with mulching, also significantly reduced the percent age of juvenile numbers/250 g soil by 79% followed by S. marcescens by 73%. . Results revealed that all previous treatments significantly increased the early and total yield. Our results confirmed that, the rhizobacterium S. marcescens came in the first rank as a promoter of all related plant growth characters, followed by tunnels and mulching treatments. Results confirmed that also the antioxidants, are considered the effective one in enhancing the activities of peroxidase and phenoloxidase as well as T:S.S% and V.C followed by the natural yeast extract.

Iron deficiency anemia is considered one of prevalent patients in developing countries, whereas it is well known that wheat flour is deficient in iron, hence, in this study wheat flour (72%) extraction fortified with celery seeds and cinnamon bark meal individually as a natural sources of iron at levels 5, 7.5 and 10 g/100 g wheat flour and preparation of biscuit samples. Iron content in wheat flour, celery seeds and cinnamon were determined. Biscuit samples were sensory evaluated and baking quality tested. Total iron and available iron were determined in biscuit samples. Biological evaluation for experimental rats designed and histopathological examination was tested for heart organ of rats. The results showed that wheat flour, celery seeds and cinnamon contained from iron 1.98, 57 and 50 mg/100 g respectively. Total iron and available iron increased in biscuit samples by increasing celery seeds and cinnamon additives compared with unfortified biscuits (control). Sensory evaluation of biscuit samples showed slight decrease in color, crunchiness and appearance while odor and taste significantly improved by increasing celery seeds and cinnamon additives compared with control. Baking quality of biscuit samples indicated increasing in weight, while volume, diameter and thickness slightly decreased by increasing celery seeds and cinnamon additives compared with control. Biological evaluation revealed that mean values of hemoglobin, hematocrit, red cell count, mean corpuscular volume, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, serum iron and serum ferritin significantly improved after 8 weeks in groups rats fed on biscuits fortified with celery seeds and cinnamon compared with control. histopathological overhaul declared amelioration in ogran heart for groups rats fed on biscuits fortified with celery seeds and cinnamoin compared with anemic control

Egyptian radish sterilized seeds were sprouted for 3 days using tap and saline water NaCl 2000 ppm to study sprout characters, chemical composition, protein fraction and safety aspects such as microbiological examinations and biogenic amines were investigated at 3 days old. The results indicated that sterilized seeds increased sprout growth compared with non-sterilized. Seeds sprouting increased in protein content, moister, ash and fibers while carbohydrate, lipid content and energy decrease in etiolated sprouts. Using saline water and seeds sterilization for sprouting increased albumin, globulin and glutenin fractionation but decreased prolamin compared with sprouts produced with tap water and without seed sterilization. Using sterilization by 2% calcium hypochlorite of seeds before sprouting led to decreasing in total bacterial count compared with non-sterile seeds sprouts, the same was in total coliform, total yeast and total fungi counts. The sprouts product which washed with saline water was contain total bacterial count less than which washed by tap water. All sprouts under investigation were free from feacal coliform and all examined pathogenic microorganism under investigation like Staph. aureus, B. cereus and Salmonella spp. Use sterilized seeds for sprouting caused big decrement on biogenic amines content of radish sprout. Radish sprout contain biogenic amines but it is lower than previous ranges, sprouts can be considered a safe food and germination of seeds either use tap or saline water.

Four common Egyptian Agricultural by products used for ruminant feeding were treated with different concentrations of Probiotic (ZAD) to study the effect of treatment on chemical composition of roughages. Roughages used were rice straw (RS), wheat straw (WS), corn stover (CS) and sugar cane bagasse (SCB). Concentrations of ZAD tested in this study were 0.05, 1.0, 1.5 and 2 ml/Kg of roughage. Roughages were mixed with ZAD solution and incubated anaerobically for 4 weeks. Results indicated that treatments decreased crude fiber (CF) contents of all roughages by 17 % in CS to 30% in SCB and increased EE by multiplication of 1.45 times in WS to 4.9 times in SCB. Statistical analysis showed no significant interaction between roughage source and ZAD concentration on chemical composition of roughages except for crude protein where interaction was significant (P<.05). Results also indicated that ZAD concentration over 0 ml/kg affected CF & CP contents, it was also noticed that CP of RS showed the highest response for treatment followed by SCB and CS, respectively. Crude protein of WS was not affected by different ZAD concentration. It was concluded that ZAD concentration of 1 ml/ 1 Kg of roughage is recommended for treatment to improve roughage chemical analysis.
