The edible coatings are a suitable method to decrease oil uptake in fried foods. In this study, the effects of milk protein co-precipitates aggregated using different types of minerals (CaCl2: 17 mM, FeCl3: 18 mM, ZnCl2: 18 mM, and MgCl2: 20 mM) and affected on the properties of fried potato strips were evaluated. Edible coating solutions were performed at two concentrations (%2.5 w/v) and (%5 w/v. According to the results, coated potato slices with edible coating solutions based on milk proteins co-precipitated by MgCl2 (%5) recorded higher hardness value among all the salts before frying process. Generally after frying process, coated French fries with edible coating solutions were the hardest comparable with uncoated (control) French fries, at the %2.5 w/v concentration the higher hardness value was recorded by coated French fries with CaCl2 milk protein co-precipitates and at the %5 w/v concentration the higher hardness value was recorded by coated French fries with milk protein co-precipitates ZnCl2. The experimental results showed that the coating solutions based on milk proteins co-precipitated had a positive and great effect on reducing oil uptake. In conclusion, The edible coating solutions based on milk proteins co-precipitated prepared by ZnCl2, MgCl2 at concentration %5 (w/v) reduced oil adsorption more than other coating solutions and in the same time increased the moisture content of final products sequentially compared with uncoated (control) samples. According to the sensory test, coated French fries with milk proteins co-precipitated by MgCl2 had the higher sensory evaluation degrees in appearance, color, taste and overall acceptability, while coated French fries with milk proteins co-precipitated by ZnCl2 got the highest sensory evaluation degrees for texture.

In this study, four pomegranate cultivars were selected in Halabja City. Their physical properties such as peel, arils, juice, seed, and juice concentrate percentage, chemical properties, and some phenolic and sugars compounds of the juices and juices concentrate was compared among all cultivars. Of all four cultivars (Wonderful, Swra hanar, Salakhani, and Kaua hanar), Wonderful and Salakhani presented the highest pH values in juice and juice concentrate and they obtained a signififcant percentage of juice concentrate, total sugars, total anthocyanin, total phenols, and ascorbic acid. Other cultivars presented also individual properties such as high phenolic compounds were studied and interesting juice concentrate percentage content (Swra hanar cultivar) and the highest arils percentage and high amounts of fructose, sucrose, glucose, and ascorbic the acid in juice and juice concentrate content (Kaua hanar cultivar) and highest juice percentage (Wonderful cultivar). Thus, this work will help pomegranate producers in selecting the extreme appropriate cultivar depending on its final utilize, especially being convenient for fresh consumption or juice concentrate.

This study was carried out to investigate  thermal treatments, immersing in black seed and flaxseed oils on postharvest quality pomegranate fruits cv. Salakhan . Fruits were randomly divided into two experiments: First, thermal treatment by which fruits are immersed for four minutes at 25, 40 and 50°C in hot water (HW), and fruits are exposed to hot air (HA) for one hour at 40 and 50°C plus control treatment. Second, fruits are immersed for 4 minutes in 1 and 2% for the black seed and flaxseed oil, plus control treatment. Then, fruits are placed in the storage at 5±1 ºC and 85-95% of relative humidity for four months. Both experiments performed by using Complete Randomize Design. The results were indicated that soaking fruits in HW for four minutes at 40°C significantly decreased the weight loss and physiological disorder, whilst significantly increased most of studied attributes compared to control. However, HA treatments exposure for 1 hour at 40 and 50°C, with increasing in the HA levels, decreased the weight loss and physiological disorder, but increased some of studied attributes compared to control. Moreover, the immersing fruits in 1% black seed or 1% flaxseed oil significantly reduced weight loss and physiological disorder. In addition, the immersing fruits in 1% flaxseed oil lead significantly increased most of studied attributes compared to control.

The drying process plays an important role in heat-sensitive product dehydration. This study was conducted to evaluate the response of three species of mulberry fruit (Morus nigra L. (Black mulberry), Morus alba L. (White mulberry), and Morus alba L. (White shahtoot) grown in Halabja, Kurdistan region, Iraq. Four levels of ascorbic acid treatment at 0%, 10%, 20% and 30% lthen, divided into two groups; the first dried under solar radiation the second dried by one of the very high-quality machines (oven) for drying all kinds of vegetables and fruits. The mulberry fruits were harvested at the ripening stage by hand in April 2021 from the trees 10 years old. The results appeared that black mulberry is significantly superior that has higher moisture and total sugars content while having the lowest ash content and polyphenol oxidase activity on the two other species. Additionally, the ascorbic acid treatment significantly decreased total sugars content and peroxidase activity, while significantly increasing moisture content and polyphenol oxidase activity in fruits as compared to untreated fruits. Furthermore, sun drying significantly increased the fruits content of moisture, ash, total sugars, and polyphenol oxidase activity as compared to oven drying.
