Bunium persicum Boiss is a critical medicinal wild growing plant in Iran dry areas. In this study, Lactobacillus acidophilus was exposed to stress with B. persicum essential oil (BEO), NaCl, bile salts, and their combinations by 50 minimum inhibitory concentration (MIC) and then inoculated to the yogurt samples, which were stored at 4°C for 28 days. Indepen-dent parameters in this article are BEO 500 and 1000 ppm that the physicochemical, sensory properties, and L. acidophilus of viability in yogurt samples were assessed within the time. A steady increase in syneresis percent-age and acidity was observed, while pH values were reduced in all samples. The L. acidophilus survival decreased during storage time in all treatments. In addition, sensory scores showed a reduction trend in the samples. The survival rate of probiotic bacteria is also impacted by redox potential. Increasing the oxidation and resuscitation potential and increasing the hydrogen peroxide concentration due to the bacteria metabolic activity are among the factors that reduce the probiotic bacteria population in yogurt during storage. The most viability of L. acidophilus under stress with BEO compared with other stress treatments may be due to slight changes in pH during this period than in the stress treatments. Generally, it can be argued that the usage of BEO, NaCl, and bile salts at a MIC of 50% in yogurt stored in the refrigerator for 21 days provided a suitable environment for the storage and transmission of L. acidophilus, as recommended to the consumer and, therefore, the current results confirmed that the addition of probiotic and these materials improved the physicochemical and sensory characteristics of yogurt.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2021-01-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45210276","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}

Recently, scientists recognized that human wellness and healthy life are going to face challenges in the near future because of the vulnerability of agriculture and nat-ural resources. It is due to imbalance and unnecessary use of synthetic agricultural inputs in traditional farming systems. Therefore, improved agricultural technology has to ensure, in traditional farming, safe agricultural produce and bringing down of environmental pollution. Recently, nanotechnology (NT) has been recognized as a promising next-generation technology in the field of agriculture. As an environment-friendly and economically viable tool, the potentiality of nanomaterials (NMs), such as nanosensors, nanopesticides, nanofertilizers, nanocarriers, nanochips, and nano-packaging, has shown great prospect in improving safe agricultural productivity and upholding of environmental safety. Because the use of NMs decreases imbalance and unconscious utilization of synthetic fertilizers and pesticides, this minimizes the loss of nutrients and lead to improved agricultural productivity thru the smooth distribution of fertilizers and pesticides, and also improving water and nutrient effi-ciency. The current review concentrates on the utilization of NT for agricultural sustainability and environmental safety.","PeriodicalId":20868,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2021-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44459697","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 the fermenting process, the bacterial community of spontaneously fermented fish is important for its flavour and quality. However, very few studies have been conducted about the relationship between bacterial community and development of flavour involved in the salt-fermentation of carp. Therefore, we explored this relationship by determining the flavour components, including amino acids, and changes in volatile flavour and bacterial metabolite. Samples were taken during fermentation on the days 0, 10, 20, 30, 40 and 50. The second-generation 16S recom-binant DNA (rDNA) sequencing was performed to analyze the composition of bacteria. Contents of amino acids were determined by reverse-phase high-performance liquid chromatography combined with ultraviolet detection. The volatile components were analyzed with solid-phase microextraction–gas chromatography-mass spectrometry. Enterococcus, Lactobacillus, Lactococcus, Leuconostoc, and Staphylococcus were the dominant bacteria. The bidirectional orthogonal partial least squares approach was used to analyze the correlation between bacterial succession and flavour component dynamics. This study would help to better understand the role of bacteria in the fermented fish meat flavour and support the industrial production of fermented fish.","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":"67104610","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}

Hence, the influences of chromium (Cr) speciation on neonicotinoids bioaccessibility were investigated and the potential health risk based on the oral bioaccessibility was evaluated. Bioaccessibility of four neonicotinoids in apple and pear was measured using three common in vitro methods (SBRC, PBET, and IVG). Bioaccessibility of neonicotinoids in apple and pear varied between in vitro methods, which may reflect the difference of determination parameters (i.e., pH values, incubation time, and constituents). The neonicotinoids bioaccessibility was remarkably reduced by 17.21–81.21% and 11.61–73.70% with the addition of Cr(III) and Cr(VI), respectively. Risk assessment based on the hazard quotient (HQ) with bioaccessibility revealed that exposure to pesticide residues in the tested fruits were all below levels that might pose a health risk. These findings are of theoretical value for the safety evaluation of pesticide residues on food.","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":"67104676","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}

This study aimed to investigate the inactivation effect of dielectric barrier discharge (DBD) plasma on horseradish peroxidase (HRP), a typical plant peroxi-dase. The results showed that DBD plasma caused inactivation of HRP in a time-and discharge power-dependent manner. The HRP activity decreased by 32.5, 50.6, 65.5, and 75.4%, respectively, after 2, 4, 6, and 8 min of exposure to DBD plasma at 57.6 W. The efficacy of DBD plasma for HRP inactivation was enhanced on increasing the dis-charge power from 6.0 to 57.6 W. Intrinsic fluorescence spectra showed that DBD plasma induced obvious structural changes in HRP. DBD plasma also caused fragmentation and carbonylation of HRP as well as the oxidative degradation of heme, which might be due to the reactive species in plasma. After DBD plasma exposure at 43.0 W for 8 min, there was approximately an 8.4-fold increase in surface hydrophobicity of HRP. After exposure to DBD plasma, the aggregation of HRP was observed by using atomic force microscopy analysis. In conclusion, DBD plasma causes structural changes and chemical modification of HRP, which may be responsible for the loss of enzymatic activity. These data contribute to the application of cold plasma in the control of enzymatic browning of food products during processing and storage.","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":"67104661","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 pesticide residues in both Kale and Pakchoi were chlorpyrifos and cypermethrin. This research was to study the efficiency of pesticide residue reduction in Chinese kale and Pakchoi samples by using various household wash processing. The process included washing with normal water, 0.10% NaCl, baking soda, water flowing, and blanching. Pesticide residues were extracted from Chinese kale and Pakchoi to determine the amount of chlorpyriphos and cypermethrin residue by using analytical tools such as Gas Chromatography— Flame Photometric Detector (FPD) and Gas Chromatography—Electron Capture Detector (ECD). The results showed that the household processes for reducing the chlorpyrifos residue in Chinese kale and Pakchoi were the following: residues were reduced by 52.70–65.41%, 58.33–62.14%, 59.46–80.52%, and 46.04–62.85% when washed with normal water, 0.10% NaCl, baking soda, and water flowing through, respectively. Similarly, the household processes for reducing cypermethrin residue in Chinese kale and Pakchoi were the following: residues were reduced by 51.13–66.29%, 33.75–45.65%, 38.14–63.64%, and 44.88–61.63% when washed with normal water, 10% NaCl, baking soda, and water flowing through, respectively. Also, blanching reduced the chlorpyrifos residue by 37.96–50.44% and the cypermethrin residue by 47.86–52.42%. Therefore, while washing vegetables by soaking and dissolving substances, baking soda is the most effective when used for washing for at least 15 min to reduce the residue of pesticides. The consumers should be provided vegetables that are cleaned and have had a proper washing for removing pesticide residues and toxic residues.","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":"67104650","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}

Every 15 days, the meringues were tested for physicochemical and microbial qualities. Package type, storage temperature, and storage time all influenced the overall meringue quality. This study revealed that meringues kept at 40°C experienced more loss of quality than those kept at 30°C. During storage, meringue’s lightness and yellowness diminished while redness increased, and the sample volume shrunk. The control samples were significantly more affected than the other cases. The sample’s weight, moisture, aw, and pH were highest in the control samples when stored at 40°C. Textural profiles such as hardness, chewiness, cohesiveness, fracturability, gumminess, and springiness decreased in all cases with stor-age time, whereas adhesiveness and resilience increased. The M-LDPE and PET packages maintained the sample texture. The radical scavenging abilities of the samples did not significantly differ by the alternatives tested, but a gradual increase was noted during prolonged storage. The control samples had significant levels of pathogenic bacteria (Escherichia coli and Salmonella) and spoilage microorganisms (yeast and mold), reducing the shelf life to 90 days. In contrast, M-LDPE and PET packages maintained the sample qualities throughout the testing period of 120 days.
