In this study, 1 wt%, 3 wt% and 5 wt% of litchi pericarp extract (LPE) was added into qua-ternary ammonium chitosan (QAC) and polyvinyl alcohol (PVA) matrix to develop active packaging films. The structural, physical and functional properties of QAC-PVA (QP) films were compared with LPE (QP-LPE films) and without LPE (QP films). Results showed QP film had a heterogenous cross-section whereas QP-LPE films displayed rough and uneven cross-sections. After adding LPE, the N–H, O–H, C–H and C=O stretching bands of QP films shifted due to the formation of intermolecular interactions between LPE and film matrix. LPE made the colorless QP film turned brown. QP-LPE films presented lower ultraviolet–visible light transmittance than QP film. After adding LPE, film thickness increased from 0.091 to 0.103 mm, film water vapor permeability increased from 14.98 × 10−11 to 17.21 × 10−11 g m−1 s−1 Pa−1, film oxygen permeability increased from 0.16 to 0.22 cm3 mm m−2 day−1 atm−1, film tensile strength increased from 14.10 to 17.41 MPa, and film elongation at break decreased from 36.94% to 25.13%. QP-LPE films quickly released polyphenols in distilled water within 4 h and displayed potent antioxidant activity. The antimicrobial ratio of the film against Escherichia coli, Salmonella typhimurium, Staphylococcus aureus and Listeria monocytogenes was elevated from 50.40−68.04% to 58.93−91.38% after adding LPE. Results suggested QP-LPE films could be utilized as antioxidant and antimicrobial packaging materials in food industry.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67104808","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}

Encapsulation of hydrophobic compounds in liposome system is an ideal solution for protecting them against destruction during storage. An important advantage of liposomes is the encapsulation of hydrophilic, hydrophobic and amphiphilic compounds by using natural phospholipids, such as lecithin, with beneficial effects. The aim of this study is to encapsulate the bene kernel oil in the form of microliposomes. For this purpose, the effect of composition of liposomes based on lecithin and cholesterol was studied using the Mozafari method. Liposomes are prepared using lecithin and cholesterol in the ratios of 60:0, 50:10, 40:20 and 30:30. Particle size, size distribution, zeta potential and encapsulation efficiency were charac-terised. According to the result, the size of liposomes was dependent on their composition, but the wasaffected significantly affected by adding cholesterol (P < 0.05). Average diameter of the particles was between 4 and 9 µm. Liposome with a ratio of 40:20 had the smallest size. By applying cholesterol, zeta potential increased from 16.4 mV to 32.39 mV, which indicates electrostatic stability of liposomes. In general, with encapsulation efficiency of 84.33%, the ratio of 40:20 is considered as an ideal concentration in the formulation of microliposomes. Based on the results, bene oil-loaded liposomes with a lecithin:cholesterol formulation ratio of :as 40:20 was chosen as an optimal formulation because of its smaller particle size, higher zeta potential and suitable stability, which can be used in trapping, delivering and releasing hydrophilic, adipose-friendly and amphiphilic compounds (dual-friendly).","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2020-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41905658","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}

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":null,"pages":null},"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":null,"pages":null},"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}

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":null,"pages":null},"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}
