“…Apart from its agricultural and commercial importance in the Arabic Gulf region, the fruit has high nutritional value including dietary fibers, carbohydrates, proteins, vitamins, minerals, phenolic, tannins, and antioxidants compounds [3][4][5][6]. Based on Arabic terminology, the fruit's maturation and developmental stages were classified as Hababouk, Kimri, Bisr or Khalal, Rutab, and Tamer [7].…”

Despite the immense capabilities of the date palm, maintaining the fruit’s quality, marketability, and shelf life is still a challenge. This study aimed to assess the synergistic effect of a preharvest spray application of a natural elicitor chitosan, (Ch) 1% alone and in combination with salicylic acid (SA) 2 mM and calcium chloride (Ca) 3%; (Ch,SA, Ca,Ch+Ca, Ch+SA, Ch+SA+Ca), on the quality parameters, storage life, and bioactive compounds content of date fruit from ‘Khasab’ cultivar during cold storage for 60 days. The obtained results revealed that all treatments significantly retard senescence/decay of the fruit compared to the control. Ch+SA treated fruit followed by Ch, and Ch+SA+Ca had the lowest weight loss, color change, and the least decay after 60 days of storage. Ch+Ca, SA, Ca treated fruit had significantly lower levels of total soluble solids and highest total phenolic, tannins, and flavonoids contents compared to the control fruit. Antioxidant activities were found in all treatments, with significantly higher effect in Ch+SA+Ca and Ch+SA compared to the control. Our results provide an evidence for a synergistic effect of elicitors combination to extend the shelf life of date fruit during cold storage by preserving its quality and decreasing senescence/decay and recommend it as a promising strategy.

“…Date palm (Phoenix dactylifera L.) is one of the most successful fruiting trees in semiarid and arid areas around the world, and it is regarded as a significant subsistence crop (Mohamed et al, 2014). Date is the most popular fruit consumed in the Middle East regions (Awad et al, 2011), and contains considerable amounts of essential nutrients, vitamins and minerals, carbohydrates, and dietary fibers, antioxidants, and phenolic compounds (Al-Mssallem et al, 2020;Al-Shwyeh, 2019;Bentrad and Hamida-Ferhat, 2020;Vayalil, 2012Vayalil, , 2013.…”

The ‘Khenizi’ date palm is one of the most recognized date palm cultivars. It is commonly consumed at the Bisr, Rutab, and Tamr stages of ripening; however, the fruit has a short shelf/storage life at this stage of maturity even with refrigeration. Preharvest application of a natural elicitor chitosan (Ch) has been reported to have positive influences on quality and shelf life of many fruits; however, synergetic effects of Chand other natural elicitors have not been investigated. Therefore, this study aimed to investigate the synergistic effect of preharvest spray treatments with Ch 1% in combination with calcium chloride (Ca) 3% and salicylic acid (SA) 2 mm on ‘Khenizi’ date fruit quality and storage life. Fruit quality parameters, including physical and physiochemical characteristics, phytochemical content, and bioactive properties, were determined at harvest time and during cold storage at 2 °C for 60 days for 2 months. Our results revealed that a combination of these elicitors had significantly influenced the fruit quality during storage compared with control. For instance, Ch+SA and Ch+Ca+SA treatments improved total phenolic content (TPC), and the antioxidant activity at harvest and at specific times during the postharvest storage period. Furthermore, Ch+SA+Ca treatment significantly delayed senescence in treated fruits during cold storage for 45 days as compared with other treatments and the control. In addition, Ch+Ca-treated fruits had the lowest weight loss after 45 days of cold storage. Ch+SA treatment had the lowest microbial counts as compared with other treatments, including the control. The significance of this study is that it provides evidence that a combination of these elicitors has the potential to improve fruit quality at harvest, as well as during postharvest storage Future studies should be directed to fine tune the concentrations and combinations that may have commercial applications.

“…Dates are a good source of essential amino acids (Al-Farsi et al 2005), contains histidine and arginine, which has an essential role in the physiological functioning of the correct human body (Bentrad and Hamida-Ferhat 2020;Mrabet et al 2019). The amount of proteins in fresh date pulp ranges from 1.2-6.5% (Alharbi et al 2021;Rybicka et al 2021;Taleb et al 2016;Assirey 2015).…”

Abstract. Hamza RS, Al-Hashimi AG. 2023. Effect of different drying methods on some mineral elements, amino acids and fatty acids of the fruits of some Iraqi palm cultivars. Biodiversitas 24: 359-369. The current study aimed to produce date palm powder from low-quality local varieties, namely (Dayeri and Zahdi). The dates were dried by three methods (solar, electric and microwave) and the mineral elements of the date powder were investigated. The mineral components in the powder produced by heat treatments increased significantly, although the microwave was the best drying method. The microwave-dried Dayeri date powder had the highest levels of potassium and phosphorus, whereas the microwave-dried Zahdi showed the highest levels of calcium. A discrepancy was observed in the saturated and unsaturated fatty acids of date powder, diagnosed by gas chromatography connected to a mass spectrometer. Fatty acid levels were affected by heat treatments, a decrease in saturated and unsaturated fatty acids was recorded, especially by the electric oven drying method. Amino acids ratio varied between varieties and drying methods; the dates of the Zahdi variety contain the highest percentage of amino acids. The proline amino acid was superior to the other amino acids; the solar-dried Zahdi powder had the highest concentration of proline, while the microwave-dried powder had higher concentrations of leucine and serine. Similar amounts of phenylalanine and threonine were found in Zahdi powder that had been microwave dried. However, the amount of cysteine in that which had been solar-dried was higher. The objective of the current study is to determine some biochemical constituents of the locally considered low-quality dates in southern Iraq. These date varieties have not been investigated before for their nutritional quality.
