Agricultural exports are an important component of Egyptian exports and are one of the sources of foreign exchange needed to drive Egypt's economic development. The average value of Egyptian agricultural exports during the study period (2004-2022) ranged from a minimum of about $1099 million in 2006 to $6965 million in 2022 at a high annual average of $4303 million during the study period.
Vegetable crops are promising export crops, especially under the Agricultural Development Strategy which aims to diversify and expand the production and export of crops in which Egypt enjoys a competitive advantage and given the existence of many countries that have excelled in exporting those crops for a long time, Let's Face These Egyptian Agricultural Exports from These Countries in Global Markets s strengths and weaknesses in global markets, so that their export earnings can be maximized.
Although one of the most important objectives of Egypt's economic policymakers is to develop agricultural exports by expanding and diversifYing the production and export of crops in which Egypt has a comparative and competitive advantage in global markets However, Egypt's agricultural exports continue to have poor access to global markets compared to competing countries, as well as limited use of the comparative and competitive advantages of Egyptian export crops in the global markets and continued reliance on traditional markets on one side and inaction on the other's development.
The objective of the study is to attempt to monitor the possibilities of developing and increasing Egyptian agricultural exports to world markets. This overall objective has necessitated the study of the following sub-objectives:
- Identify the most important productive and economic indicators of the study crops in Egypt.
- The development of Egyptian exports and their importance for global exports.
- Study the development and stability of the quantity, value and price of Egyptian exports of the study crops.
- Clarify the current position of geographical distribution of Egyptian exports from the study's crops.
- Study the efficiency of foreign trade and the competitiveness of the study's crops.
- The study recommends the establishment of strong foreign trade links with African countries to develop Egyptian exports.
- Study foreign markets in terms of export dates, prices and quality.
- Attention to the quality element conforming to the standard specifications.
- Study factors affecting the supply and demand of the study's crops.
Vegetable crops are one of the most important crops to play an active role in the development of Egyptian agricultural exports. Demand and consumption of these crops are increasing at rapid rates, both fresh and manufactured as a result of population growth and high-income levels. cultivation of most vegetable crops is suitable for climatic conditions and Egyptian soil in addition, Egypt has some productive and competitive advantages for some of these earnings in the world's markets and may contribute to redressing the imbalance in the trade balance.

There is a general tendency toward wellness and good health. The objective of the research was to investigate the possibility of producing barley waffle samples substituted with different powdered broken pulses. Barely waffle prepared by partially substituting hulless barely flour with powdered broken pulses (0.0%, 40% chickpea, 40% lentil, and 30% white bean, individually) and wheat waffle used as commercial control. Waffle batter's properties were examined, as were the physicochemical and sensory attributes of the produced waffles. The density and viscosity of the waffle batter were reduced by substituting powdered broken pulses compared with the batter, which contained 100% barely flour. An increase in protein, ash, -glucan, total phenolic, and carotenoids was observed in barley waffle substituted with powdered broken pulses relative to the wheat waffle, as well as in vitro protein digestibility and antioxidant activity. However, compared with wheat waffles, backing loss decreased in all barley waffle samples. Moreover, barely waffles substituted with broken pulse powders, particularly chickpeas, had a high overall acceptance score. This indicates the great potential of broken pulse powder utilization for producing barely waffles as a functional food.

By using carrots, vegetable leaves powder, and some grains (naked barley, grits wheat and broken rice). The chemical, minerals content, the antioxidant activity, total phenols, total flavonoid, soluble and insoluble dietary fibers were analyzed as raw materials. Sensory evaluation, physical properties and minerals content were determined and RDA was calculated for falafel free of legumes mixtures for age group (4-18 years). The data showed that grits wheat had higher in fibre and protein content (14.60% and 18.88%, respectively) than barley and broken rice.Vegetable leaves powder increased in the estimated minerals of iron, calcium, potassium, zinc, phenols, flavonoid, and antioxidant activity compared to other components. The data showed that the naked barley recording 7.05, followed by carrots at 6.35, grits at 5.6, and dried dill leaves at 5.12% for nonsoluble dietary fibre content. Also, the results indicated that the second mixture which contained (42 % of naked barley and 40 % of grits wheat) had the best score (8.85) for sensory acceptability. The minerals of Fe, Ca, Zn, and K were found in much higher concentrations in the second mixture; their respective values were 3.32 and 51.33, 1.70, and 282.13 mg/100 g sample, although it was lower in oil absorption. It is recommended that falafel free of legumes mixes be produced for patients with favism due to their high nutritional value, sensory acceptance and widespread popularity.

This research aimed to utilize whole pumpkin (without seeds) and germinated chickpeas to create dry vermicelli with enhanced nutritional value. The study evaluated the chemical composition, minerals, antioxidants, total phenols, and total flavonoids in whole pumpkin powder, whole germinated chickpea flour, wheat flour (72% extraction), and the resulting vermicelli. Additionally, various aspects such as cooking quality, color, texture profile, and sensory evaluation of the vermicelli were investigated. Germinated chickpea flour had significantly higher protein, fat and fiber content (24.38, 7.6 and 5.4%, respectively) compared to other ingredients. Whole pumpkin powder was higher in ash (5.68%), radical scavenging activity (61.69%), total phenols (9.39 mg gallic acid/g sample), and total flavonoids (2.24 mg quercetin/g sample). Substituting 15% of the wheat flour with germinated chickpea flour increased the protein content of the vermicelli. Meanwhile, adding whole pumpkin powder led to an increase in fiber and ash content. Furthermore, a significant increase in mineral content was observed. Vermicelli containing 20% whole pumpkin powder displayed the highest beta-carotene content. Substituting wheat flour with germinated chickpea flour and whole pumpkin powder improved cooking quality and resulted in a darker yellow to brown color of the vermicelli. When served with milk, 100g of this vermicelli increased daily nutrient intake by up to 60.96% for protein, with iron and zinc content doubling, and beta-carotene reaching 30.1. The study successfully produced vermicelli by incorporating up to 15% whole pumpkin powder and 15% germinated chickpea flour.
