Adding the sifting meals of the terebinth and grape seeds to wheat flour mixtures caused increasing in fibers content , and decreasing in ash content ,meanwhile the protein percentage remained steady , except the highest percentages (10 , 15 % ) . Also the (10,15%) percentages adding caused a slight reducing in gluten quality as showed by related tests : (fermentation time test , SDS test , moisture gluten test ) Also the adding of tested meals caused improvement in baking quality (loaf weight during baking and during cooling) , also improvement the sensory properties of produced bread significantly comparing with control sample. On the other hand , 10 and 15 percentages of grape seed meal adding caused reducing in sensory properties of produced bread. Finally , the determined results related with rheological properties tested by Mixolap apparatus showed improvement in thermal stability of starch enzymatic activity comparing with control sample , meanwhile the other tested properties didn't affected at the same level of addition .

Adding the sifting meals of the Avocado seed to wheat flour mixtures caused increasing in folowing percentages of components: (moisture , fibers , ash , starch and total soluble sugars ) Also the (5,10%) percentages adding caused a slight reducing in gluten quality , while a reducing in gluten quality was clearly at (15 , 20%) percentages. Also the adding of tested meals caused improvement in baking quality (loaf weight during baking and during cooling) , also improvement the sensory properties of produced bread significantly , except (20%) percentage comparing with control sample. Finally , 15 and 20 percentages , only of Avocado seed meals adding caused reducing in taste property of produced bread.
A landrace (Hourani-٢٧) and two newly introduced cultivars (ACSAD-٦٥ and Amra) were grown at five different locations (JUST, Shajarah, Hawarah, Kharja and Turrah) with or without NP treatment.
Cornstarch has been added, with percentages of ( 5%, 10%, 15%,20% and 25%), to flour beans both types paste (peeled and non-peeled) prepared for the manufacture of a quick vermicelli preparation (noodles), in order to study the effect of the additi on of some chemical and organoleptic characteristics of this product and to determine the ideal proportion of corn starch added. The study has shown that there is an inverse relationship between the reduction of protein content and the increase of the fat percentage and the increase of starch proportion up to (25%) in both kinds of bean noodles: peeled and unpeeled. Increasing the ratio of starch above 15% has affected negatively the resulted noodles colour and some organoleptic characteristics such as taste and smell with the emergence of a gradual improvement of the appearance of noodles that resulted from flour peeled beans. Finally , it was found that the best ratio of added starch is 15%.
