Waste management of brewery by-products is economically and environmentally problematic. In the frame of bio-recycling, this study aims to investigate the bioconversion of brewery by-products by filamentous fungi. Pleurotus ostreatus and Lentinula edodes were grown on different substrates based on brewer’s spent grains (fresh and dry). Afterwards, fatty acids and sterols were determined. Following the selection of the suitable substrate composition for fungal growth, results showed that fatty acids composition of fungal biomasses varied significantly as a function of substrate and fungal strain. Interestingly, fungal fat might be used for human nutrition due to low SFA/UFA ratios (~0.2–0.4) within the same range of vegetal oils. Sterols profile of fungi biomass revealed the predominance of ergosterol. Also, it was found that the fungi growing on by-products slightly reduced the cholesterol contents. As such, this approach focusing on the bioconversion of by-products using fungi can provide biomasses with a fat composition suitable for feed and human consumption.

In this study, dark chocolate was enriched with white tea (WT) and jujube extracts in form of free extract and microcapsules. Each form of two extracts was added to dark chocolate in concentrations of 1, 3, 5, and 7% w/w. The microcapsules were produced using pectin/casein (10% w/w), and their particle size distribution (PSD) and Fourier transform infrared spectroscopic analysis were performed. Phenolic content, antioxidant activity, pH, moisture content, color parameters and texture of enriched dark chocolates were measured. As expected, addition of extracts caused a significant increase in total phenolic content and antioxidant properties of dark chocolates compared to the control sample (no extract added) in both free and microencapsulated forms, with a stronger effect of WT extract than jujube extract.

In order to explore the feasibility of mineral element analysis on the origin of red jujube, and to screen the effective indicators to distinguish the origin of red jujube, 34 samples of red jujube were collected from Xinjiang, Hebei, Shanxi and Gansu provinces of China. The contents of Na, Mg, K, Ca, P, B, Al, Ti, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Sr, Mo, Ba, Tl, Ge, Zr, Li, Rb, Cs, La, Ce and Nd in the samples of red jujube were determined by inductively coupled plasma mass spectrometer and analyzed by variance analysis, principal component analysis (PCA), clustering analysis (CA) and discriminant analysis (DA). The results demonstrated that the content of mineral elements in red jujube from different regions has its own characteristics. The average contents of Na and Ge in red jujube were the highest from Xinjiang province, while the average contents of Co, Cu, Zn, Se, Ba and Cs were the lowest. The average contents of Ca, Ba and Ti in red jujube in Hebei province were the highest, the average contents of K, Mn and Rb in red jujube in Shanxi province were the highest, and the average contents of Mg, P, Al, B, Ti, Fe and Cu in Gansu province were the highest. The content of Na in Xinjiang province was three times more than that of Gansu province, and the content of Rb in Hebei province was four times more than that of Xinjiang province. PCA explained 82.1% of total variation, indicating that it played a vital role in the classification of mineral elements of red jujube. Red jujube was divided into five groups at a cluster distance of 9.0, indicating that clustering analysis has achieved ideal results in the origin traceability of red jujube. By discriminant analysis, the correct discriminant rate of 100% was established for samples from Xinjiang, Hebei, Shanxi and Gansu provinces. Facts have proved that it is feasible to judge the traceability of the origin of red jujube by using multi-element analysis.

This study aimed to determine the quality and nutritional characteristics of durum wheat varieties commonly grown in Anatolia and detect changes in nutritional properties due to milling. There were significant differences in hectoliter weight, thousand kernel weight, hardness index, kernel size, ash, protein, beta-carotene contents, and SDS sedimentation values. The correlation between ash and phytic acid contents was significant (r=0.953). Over 60% reduction was observed in semolina samples’ phytic acid content compared to wheat. There were significant correlations between TDF and phytic acid contents in the durum wheat and semolina samples. Although the Zn, Fe, P, Ca, and B concentrations of the wheat samples grown in Central Anatolia were higher than those grown in South-eastern Anatolia, there was an opposite trend in their semolina samples. The results might benefit breeders in improving durum wheat’s technological and nutritional quality.

Purpose: To assess the effects of ligustrazine on the progression of hypoxia-reoxygenation (H/R), and explore the possible role of miR-211 in myocardial ischemia-reperfusion (I/R) injury and identify its potential targeting gene. Methods: The level of miR-211 in H/R-induced cells was detected by quantitative polymerase chain reaction. CCK-8, flow cytometry (FCM), and Western blot assays were performed to examine the effect of miR-211 and USP47 on the role of remifentanil against H/R injury. Bioinformatic analysis and luciferase and Western blot assays were performed to identify and verify the potential target of miR-211. CCK-8 and FCM assays were performed to detect the mechanism of ligustrazine and miR-211 in the protection of remifentanil against H/R-induced cells. Results: Ligustrazine enhanced the effect of remifentanil on H/R-induced cardiomyocytes. MiR-211 enhanced the protective effect of remifentanil against H/R injury. Down-regulation of USP47 enhanced the protective effect of remifentanil against H/R injury. Ligustrazine enhanced the protective effect of remifentanil against H/R injury through miR-211/USP47 pathway. Conclusion: Ligustrazine enhanced the protective effect of remifentanil on myocardial I/R injury by regulating miR-211/USP47 pathway.

The concentrations of chlorophyll and carotenoids were analyzed in two organs (leaves and bolting stems) of 19 varieties of Chinese kale (including four maturity periods and two flower colors). Two chlorophylls and four carotenoids were identified in Chinese kale. The concentrations of chlorophyll and carotenoids varied widely in different organs and varieties. JL-03 was a good candidate for the future breeding programs, since it contained the highest concentrations of chlorophyll and carotenoids (except violaxanthin) in leaves. Lutein was the main component of carotenoids and accounted for approximately 50% of total carotenoids. The concentrations of chlorophyll and carotenoids in leaves significantly exceeded those in bolting stems. Principal component analysis showed that organ was the main source of differences of chlorophyll and carotenoid concentrations in different varieties of Chinese kale, while the maturity and flower color have little effect. Correlation analysis identified a significantly positive correlation between chlorophyll and carotenoids in Chinese kale. These results provided evidence for improving human dietary nutrition and breeding of Chinese kale.

The study aimed to verify the effectiveness of two detection kits namely, Accuscan gold reader and RIDA total aflatoxin smart phone application in assessing levels of aflatoxins’ contamination in maize. Three regions of Kenya were selected namely, Kisumu, Makueni and Kilifi. Confirmatory tests were done using liquid chromatography tandem mass spectrometry (LC-MS/MS). The Accuscan gold reader showed mean aflatoxin levels of 14.52, 5.18, and 3.04 μg/kg and RIDA smart phone application had levels of 26.08, 26.68, and 4.05 μg/kg for Kilifi, Makueni, and Kisumu, respectively. The LC-MS/MS confirmed the presence of AFB1 and AFB2 with AFB1 of 97.5 μg/kg in Makueni and 76.2 μg/kg in Kilifi. Maize from Kilifi and Makueni was contaminated and unfit for human and animal consumption. Also, low rainfall, high temperature and high relative humidity directly increased the levels of aflatoxins, resulting in contamination. Therefore, the detection kits are recommended for use by maize farmers. Confirmatory tests should be done with maize having levels of aflatoxin above 10 μg/kg. Adequate drying and handling of maize and proper storage with good aeration should be ensured.

Food loss and waste reduction efforts have received a lot of attention recently because of their importance in enhanc-ing food security and environmental sustainability. Value addition of agricultural products is the key to a higher production rate, fewer food losses, and hence more farm income and a better economy. In Oman, agriculture is represented as the first source of life and date is considered one of the most important permanent cultivated crops. This study aimed to evaluate the value addition process of the date palm products and reveal the challenges associated with the productivity improvement in Oman. Six prominent date value-addition factories were visited for data collection. The most date value-added products found were date with nuts, date syrup, and paste, and industries are using most popular date varieties Khalas and Fardh for the value addition processes. Raw dates are supplied by three farm catego-ries and four process mechanization levels were found in these factories. The financial productivity improvement due to the value addition were evaluated. Date with nuts found to be with the highest productivity ratio that reaching up to 540% in Khalas and 360% in Fardh. Highly productive factories had high mechanization levels (ML3–4). A broader improvement in value addition industry is essential to improve the productivities. This includes increase in number of small and medium enterprises, improve mechanization levels, technology transfer, and capacity building needs and additionally to improve the quality of value-added products which will positively affect the farm income and country’s economy.

The thin-layer drying behavior of sprouted wheat (cv. PBW 550) was experimented at different drying periods, such as 24 h, 36 h and 48 h. The samples were dried in a tray dryer at 50–80οC at an interval of 10°C. The moisture ratio was fitted to the six thin-layer drying models, and the performance of the models was assessed by statistical parameters. The Wang and Singh model has accurately predicted the drying behavior of sprouted wheat for all sprouting periods and drying temperatures. In addition, the effective moisture diffusivity of grain sprouts at three drying periods (24 h, 36 h and 48 h) of sprouted wheat was increased from 1.79 × 10-9 to 2.58 × 10-9 m2 s-1, 1.921 × 10-9 to 2.781 × 10-9 m2 s-1 and 1.858 × 10-9 to 2.561 × 10-9 m2 s-1 with increase in drying temperature from 50oC to 80oC. Moreover, at the above-stated drying periods, the activation energy for sprouted wheat was 11.357 kJ mol-1, 11.428 kJ mol-1 and 9.427 kJ mol-1, respectively. Therefore, thin-layer drying of sprouted wheat was successfully simulated between 50°C and 80°C for various drying periods. This study provided imperative information to understand the drying behavior and relationship between various drying parameters of sprouted grains that could produce nutritive functional flour.

PBW 550) was experimented at different drying periods, such as 24 h, 36 h and 48 h. The samples were dried in a tray dryer at 50–80οC at an interval of 10°C. The moisture ratio was fitted to the six thin-layer drying models, and the performance of the models was assessed by statistical parameters. The Wang and Singh model has accurately predicted the drying behavior of sprouted wheat for all sprouting periods and drying temperatures. In addition, the effective moisture diffusivity of grain sprouts at three drying periods (24 h, 36 h and 48 h) of sprouted wheat was increased from 1.79 × 10-9 to 2.58 × 10-9 m2 s-1, 1.921 × 10-9 to 2.781 × 10-9 m2 s-1 and 1.858 × 10-9 to 2.561 × 10-9 m2 s-1 with increase in drying temperature from 50oC to 80oC. Moreover, at the above-stated drying periods, the activation energy for sprouted wheat was 11.357 kJ mol-1, 11.428 kJ mol-1 and 9.427 kJ mol-1, respectively. Therefore, thin-layer drying of sprouted wheat was successfully simulated between 50°C and 80°C for various drying periods. This study provided imperative information to understand the drying behavior and relationship between various drying parameters of sprouted grains that could produce nutritive functional flour.","PeriodicalId":20738,"journal":{"name":"Quality Assurance and Safety of Crops & Foods","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90146378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
