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. Generally speaking, the mean concentration of Pb, Cd, As, Zn, and Cu were 0.59 ± 0.12, 0.12 ± 0.06, 0.16 ± 0.12, 14.23 ± 4.90, and 11.10 ± 2.49 mg kg−1, respectively. The mean transfer rates of Pb, Cd, As, Zn, and Cu were 7.78, 6.29, 9.27, 12.91, and 13.08%, respectively. The estimated daily intake (EDI) and noncarcinogenic quotient (target hazard quotient [THQ]) due to the ingestion of PTEs besides the carcinogenic risk of As and Cd were considered as acceptable.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2020-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47010297","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}

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. It is also recommended to use the FTIR to monitor the spoilage in meat.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2020-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44520913","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 concentrations of essential elements, including Iron (Fe), Copper (Cu), Zinc (Zn), Manganese (Mn), and Chromium (Cr) in five types of fruits, namely, peach, apple, grape, nectarine, and golden plum, and the soil and irrigation water from six industrial zones of Markazi province, Iran, were evaluated using an inductively coupled plasma-optical emission spectroscopy (ICP-OES) technique. The noncarcinogenic risk was assessed by determining the target hazard quotient and the Monte Carlo simulation model. The highest concentrations of Fe, Mn, and Cr were observed in golden plum, while the highest concentrations of Cu and Zn were noted in grape and apple, respectively. The order of the mean of concentrations of elements in the soil and water samples were Fe > Mn > Zn > Cu > Cr. The transfer factor (TF) results indicate that studied fruits could not absorb a high amount of these elements from the soil (TF < 1). Target hazard quotient values of these elements in both adults and children were ranked as Cr > Cur > Fe > Mn > Zn. The target hazard quotient was 95% and total target hazard quotient was <1, meaning that the consumption of fruits is safe for consumers.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2020-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45884557","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}

In this study, texture parameters (hardness, springiness, cohesiveness, gumminess, chewiness, and resilience) of okra fruit subjected to chitosan (CTS) treatment and control were determined during storage. The changing pattern of texture properties and the differences between three different cultivars (Kariba, ACF, and Xianzhi) were observed at three testing stages (0, 15, and 30 days of storage), which indicated a significant cultivar-dependent pattern. The hardness, cohesiveness, gumminess, chewiness, and resilience of the fruit, both in the 1% CTS treatment group and the control group, declined along with storage time. The small fruits (length < 10 cm) scored relatively low in most of the texture parameters and rate of intact when compared with large (length ≥ 15 cm) and medium-sized fruits (10 ≤ length < 15 cm). There was a significant, positive correlation between firmness, cohesiveness, gumminess, chewiness, and resilience. Our results revealed that a 1% N, O-carboxymethyl CTS solution can effectively delay softening and maintain the texture profile of the okra fruit. In the case of Kariba (A) and Xianzhi (C), the medium-sized fruits showed better storage resistance, while the large fruit of ACF (B) showed the best storage resistance.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2020-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48706669","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}

Extraction and determination of pesticide residues were carried out by a quick, easy, cheap, effective, rugged, and safe (QuEChERS) method and a gas chromatography/tandem mass spectrometry (GC/MS/MS) system, respectively. Dissipation of chlorpyrifos-methyl, dimethoate, permethrin, iprodione, metalaxyl, and propargite in parsley followed the first-order kinetics with a half-life (t1/2) of 3.33, 3.30, 2.94, 3.52, 4.10, and 3.38 days, respectively. Based on the dissipation pattern and the maximum residue limits (MRL), preharvest intervals (PHI) of 25, 13, 18, 24, 1, and 16 days are suggested for chlorpyrifos-methyl, dimethoate, permethrin, iprodione, metalaxyl, and propargite in parsley, respectively. The estimated daily intake (EDI) of pesticides ranged from 7.37E-05 (dimethoate) to 8.00E-04 (metalaxyl) mg/kg.
