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.

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.

In field study, Eleven mango varieties, (Mangiferae indica L.) at Sharkia, Ismailia, and Fayoum Governorates, were examined to estimate the population fluctuation of the bud mite Eriophyes mangiferae Sayed, their susceptibility to mite infestation, the relation between the mite infestation and chemical contents of mango buds and the correlation between the bud mite and malformation disease. The highest population occurred during Sept. to Jan. or Feb. and the lowest population was existed during Mar. to Jun. Temperature and relative humidity had no significant effect on the mite population. The highest level of mite infestation was recorded at Sharkia followed by Fayoum and Ismailia Governorates. Mango varieties were differed in their susceptibility to E. mangiferae infestation. Zebda, Taimour, Ewais and Arnaba were the most susceptible varieties, while Mabrouka, Company, Excellent Succari and White Succari were the least susceptible ones. On the other hand Mesk, Geolck and Alphonse varieties showed moderate susceptibility to mite infestation. Buds of some high susceptible varieties possessed a lower values of total carbohydrates and total soluble sugars than some moderate or susceptible varieties to mite infestation. Phenol contents recorded a higher levels in the most of susceptible varieties while a lower levels were found in the most of moderate and low susceptible varieties. The total soluble proteins and amino acids recorded a higher values in some susceptible varieties. The susceptible characteristic was positively correlated with total soluble proteins and amino acids while negatively correlated with the total carbohydrates and total soluble sugars. However the phenol content showed no clear trend. Obtained results also revealed that mango varieties had varying degrees of floral malformation, Company, Alphonse and Geolck were the most susceptible varieties, while Zebda var. was the most resistant one. Statistical analysis showed a negative correlation between the eriophid bud mite and the incidence of malformation disease. Zebda var. harboured the highest number of mites but exhibited the lowest percentages of malformation, whereas the opposite trend was observed with company var
