Chocolate is a unique food and one of the important sources of biologically active substances which have shown a special antioxidant effect in the human body. In recent years, with the advent of functional foods, researchers are seeking to strengthen micronutrient products to increase their health effects. The proposed research is for the enrichment of chocolate, oleaster powder in levels of 5, 10, 15 and 20% instead of sugar. The researchers proved that oleaster is rich of polyphenols, flavonoids, vitamins, tannins and especially fibers. And used in traditional medicine as an anti-nausea drug due to its high tannin content. In this study, to increase the antioxidant and sensory properties, Mentha extract with constant dose added to all treatments and functional chocolate was produced. The results of the experiments indicated that polyphenols, flavonoids, anthocyanins increased, as well as an increase in the free radical DPPH concentration in the presence of oleaster powder. In this research, due to the positive effect of tannin in eliminating nausea, the tannins and the kinetics of its decomposition (constant K) and the half-life of tannin T1/2 in chocolatewere measured that the results indicate that this composition is stable in mint chocolate. Due to the undesirable gass taste caused by high tannin, the mint extract had a positive effect on improving the sensory properties and the mind of the audience was primarily concerned with the mild extract coldness. According to the results, this product can use as a nutritional and nutritional health enhancer. [ABSTRACT FROM AUTHOR]

This study was conducted on the mint farmers and extension agents in Al-Madinah Al-Monawara. The results showed that 76% of farmers were 50 years old or more, and almost all of them born in village and were illiterate. Two mint varieties (Hassawi and Maghrabi) were cultivated in March and surface or drip irrigated. The percentage of farmers using cattle manure fertilizer reached 44%. Farmers did not control diseases, but handily controlled weeds and chemically controlled insects. The main problems of the farmers were weeds effects, high temperature effects, pest effects, irrigation water salinity, and low purchasing price. Mint farmers desired in marketing procedures, increasing mint price, planting improved varieties, pest control and a farmers mint producers committee. The main knowledge sources of farmers were rare, as were the extension services to farmers. Most of the extension agents were 39 years old or more. From them, 80% had secondary certificate only and less than 5 years experience in agricultural extension. Agricultural extension agents stated that the high production equipment price, marketing, storage, high water salinity are the main problems of mint farmers. Planting the improved mint varieties and establishing a farmers committee are the main solutions of the farmers' problems. The main knowledge sources of the extension agents were the agricultural printings, arabic magazines and radio and TV programs. Among the agricultural extension agents 50% reported that the main problems affecting extension effectiveness were low money promotion, large management work and low number of agricultural extension agents in Al-Madinah Al-Monawara region.
