Low level of soil organic matter and calcareous parent material decrease the bioavailability of these micronutrients to plum plants. Thus, less micronutrients uptake resulted in deterioration of plum fruit quality and decreased yield. On the other hand, balance and correct combination of micronutrients used as a foliar has potential to overcome this problem. Foliar application method provides plants a chance for rapid and easy uptake of micronutrients. Therefore, the present research was carried out to select the best combination of micronutrients using foliar method. Aim of the study was to select a balanced combination of micronutrients for better production and improved quality of plum (Prunus domestica L., variety Fazal manai) fruit. Seven treatments in three replications were applied. Our results showed that the quality of fruit was significantly improved through the application of T6 micronutrients consortia. A significant increase in total soluble solids (16%), fruit yield per tree (92%) and fruit size (12%) validated the effectiveness of treatment T6 (Zn + Cu + Fe + Mn + B = 0.5% + 0.2% + 0.5% + 0.5% + 0.1%) over control. Application of treatment T6 also enhanced quality attributes, that is, juice acidity (22%), juice sugar (22%) and juice contents (16%), as compared to control. It is concluded that use of treatment T6 as a foliar application is a better approach for significant improvement in quality and yield attributes of plum in micronutrients deficient conditions.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":"12 1","pages":"32-40"},"PeriodicalIF":4.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45195482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The objective of this study was to compare the physical, antioxidant and antimicrobial characteristics of its essential oil (EO), based on the process parameters and extraction methods using hydrodistillation (HD) and microwave-assisted hydrodistillation (MAHD), and assessing presence of fatty acids. The process performance as well as the colour parameters, refractive index, fatty acid profile, antioxidant activity and antimicrobial activity were evaluated. The best process conditions for HD were 90 min, 420 W and 150 g 1000 mL–1; for MAHD, these were 90 min, 700 W and 200 g 1000 mL–1, with yields of 0.45 and 0.49 mL 100 g-1 and antioxidant capacities of 2.38 and 3.92 μmol Trolox g-1 respectively. The collection season, extraction method and its parameters affected the yield and fatty acid profile, influencing EOs’ activity. In terms of mass of herbs, process time as well as energy efficiency and environmental impact, the extraction of MAHD was 8% more efficient. EOs extracted by both methods show a slight inhibitory effect on Streptococcus sp. and Bacillus cereus, and MAHD EO showed a highly inhibitory effect on Streptococcus Group A. The type of extraction method and the process parameters could be set to obtain suitable EOs according to its potential industrial application.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":"12 1","pages":"36-49"},"PeriodicalIF":4.0,"publicationDate":"2020-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44045157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The total soluble solid concentrations (TSSC) and titratable acidity (TA) increased continuously throughout maturation, and the peak respiratory and ethylene production rates occurred on the 3d and 5th day of postharvest, respectively. Phenylalanine ammonia-lyase (PAL) activity steadily increased, catalase and polyphenol oxidase (PPO) activities decreased significantly on the 1st day and then gradually increased, and peroxidase activities increased during the initial 3 days, and then decreased at later stages. The volatile fingerprints of flesh samples from the five senescence stages were successfully established using gas chromatographyion mobility spectrometry (GC-IMS) combined with principal component analysis, and 32 typical target compounds and 35 indeterminate compounds were obtained.

However, as there are several types of plasma designs, their efficacy in degrading major pesticide residues, such as chlorpyrifos (as a hazardous chemical), should be explored. This study was conducted to assess the decontamination efficacy of 8 min of arc and dielectric barrier discharge (DBD) plasma on chlorpyrifos pesticide-water samples at a concentration of 2 mg·L-1. The plasma-treated samples were assessed by liquid chromatography-mass spectrometry (LC-MS) and compared with the control (untreated) sample. In addition, the effects of plasma processes on some physical properties of samples were studied. According to the results, plasma-treated samples showed similar physical characteristics (e.g., refractive index and color values) to those of the untreated samples. While the temperature of the samples remained steady during the DBD plasma treatment, arc plasma changed the temperature of the sample at a rate of about 3.75°C·min–1 and yielded a sample with a final temperature of 60°C. However, contrary to the general belief that plasma is an efficient technique for pesticide degradation, chemical analyses showed high resistance of chlorpyrifos against both arc and DBD plasma under the conditions used in the present study. Therefore, the possibility of high resistance of pesticide pollution to this emerging technology should be considered. Also, further studies on the efficiency of the selected plasma system for removing pesticide pollution (e.g., during water and wastewater treatment) at industrial scale is needed.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":"12 1","pages":"9-17"},"PeriodicalIF":4.0,"publicationDate":"2020-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45177256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Besides, the transfer rate of PTEs from made tea into tea infusion was investigated, and the related health risk for consumers was assessed. According to the results, the content of the PTEs is dependent on the type of tea (black or green), the place of cultivation (Iran or India), and the supplied form (both bagged and loose-leaf ). The concentration of Pb, Cd, and As in green tea was significantly lower than black tea (P-value < 0.05). On the other hand, the contents of Zn and Cu in green tea were higher than the corresponding values for black tea. The mean concentration of Pb, As, and Zn in bagged tea samples was significantly higher than those of loose-leaf tea, while the Cd and As levels in Iranian tea samples were significantly lower than the Indian samples.

In this study, the growth rate, including the lag time of Listeria innocua in ground lamb as a function of storage temperature (4, 10, 25, and 37°C) influence of the coriander seed essential oil (CEO), as an antimicrobial agent, was modeled. Fourier-transform infrared (FTIR) spectroscopy was used to monitor chemical changes in investigated specimens that may indicate spoilage in ground lamb. Results showed the use of CEO reduced growth rate of L. innocua, to approximately 0.0051 (CFU/h) for a sample containing CEO and to 0.042 (CFU/h) in control samples cultivated at 4°C. Increasing the cultivation temperature from 4 to 37°C led to a 5-fold increase of the growth rate (0.042 to 0.222 in the control sample) and 28-fold growth from 0.0051 to 0.147 in a sample containing the CEO. Minimum-recorded temperatures (Tmin) were –0.57 and 0.60°C for the control sample and a sample containing the CEO. The comparison of FTIR spectra of samples during the shelf life indicated that the increased shelf life and bacterial growth results in decreased moisture (1600–1650 cm–1) and protein content in the samples; while the intensity and sharpness of peaks increased in the range 1000–1100 cm–1, indicating the impact of bacterial activity on amounts of amines and amino acids. In conclusion, the CEO increased the L. innocua growth rate lag phase and improved the shelf life of the ground lamb.
