The aim of this study was to record the post-harvest storage/conservation structures for maize in southern and central Benin, and to analyze the factors associated with maize growers' choice of each storage structure. Then, 530 maize growers were interviewed in 24 arrondissements of 7 communes, one commune per department. The communes with the highest average maize production over the last 5 years were selected. The quantitative survey was followed by focus groups. Eleven storage/conservation structures divided into 4 categories were used by producers. The time length of the structures varied according to the type. The adoption of a structure depended on the storage form used by the grower, his PDA (Agricultural Development Pole) and the commune. The adoption of granaries made of local materials by producers was affected by level of education (P = 0.024), the producer's main activity (P = 0.026), the storage method used by the producer (on the cob with husks: P &lt; 0.001 and without husks: P = 0.001) and the lifespan of the storage structure (P &lt; 0.001). The use of rooms/stores by growers for bulk storage on the ground is affected by the grower's PDA (P = 0.042), the lifetime of the structure (P &lt; 0.001) and the duration of storage (P = 0.008).

This review focuses on the application of four non-thermal physical field technologies in grain storage: cold plasma, pulsed electric field, ionizing radiation, and ultrasonic treatment. It presents the fundamental principles and mechanisms of these non-thermal physical field technologies, outlining their impact on quality attributes such as color, texture, and flavor, as well as nutrients such as starch, protein, fat, and bioactive substances during grain storage. This review also discusses the application of non-thermal treatments to enhance grain quality and extend shelf life.

Current moisture measurement methods often necessitate sophisticated and costly equipment. This paper introduces an approach employing real-time rice moisture content determination and detection of spoilage (specifically wet spots) within a storage facility achieved through the utilisation of radio waves operating at 2.4 GHz and 868 MHz, along with an ensemble-based machine learning algorithm. Experimental samples spanning from 12% to 30% moisture levels were collected, then subjected to pre-processing, and subsequently employed to train the Ensemble-based Rice Moisture Content and Localisation (eRMCL) algorithm. The eRMCL produced an effective prediction of both rice moisture content and the localisation of wet spots within the grain storage unit. The results show that compared to support vector machine, random forest, and machine learning methods, the eRMCL algorithm had the best performance metrics, with an accuracy of 94.8% in predicting the moisture content and location of spoilage in storage. The measurement of moisture content and the identification of wet spots in rice storage using the dual frequency wave approach were found to be more accurate than with a single frequency band. Thus, the dual frequency band is a novel method for the determination of the moisture content of stored rice and the localisation of the spoilage area.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"108 ","pages":"Article 102399"},"PeriodicalIF":2.7,"publicationDate":"2024-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142088005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The effects of GA-g-CS treatment on postharvest physiology, aromatic volatile content, amino acid content, and fatty acid content of apricots were analyzed.

The results demonstrated that reducing polyphenol oxidase (PPO) activity and improving peroxidase (POD) activity could delay fruit browning and aging. The application of 1% GA-g-CS effectively preserved the levels of esters and ketones in Saimaiti apricots throughout the storage period. Moreover, it decelerated the decline in aldehyde content and efficiently decreased the production of ethanol during storage.

Despite having agricultural resources, the country still struggles to supply wheat and continues to import tons of wheat from different countries. Moreover, being a tropical country, the weather conditions exacerbate the parameters in defining grain quality, and thus, impact the preservation of grains in bulk storage systems. This study aims to understand the fluctuations of moisture content over time and its impact on grain quality and identify trends to utilize in optimizing storage systems management practices. Furthermore, this study investigated the moisture content variations, analyzed the temporal dynamics, and forecasted future trends using the ARIMA model, which can effectively handle time series data and has been applied in several agricultural applications. From the correlation patterns from lag intervals of the correlogram, there is a total of 24 ARIMA models generated with varying (p, d, q) values. These models were then evaluated using log-likelihood, AIC, RMSE, and MAE to select the best-performing and most appropriate model for forecasting wheat moisture content data. Out of these 24 models, Models (4,0,3), (4,0,4), and (1,0,0) are the top performing models, however, Model (4,0,3) emerged as a strong forecasting model in predicting wheat moisture content trends for the forthcoming two-year horizon. Its evaluation performance resulted in a log-likelihood of −69.38384, AIC of 156.7677, RMSE of 0.4248, and MAE of 0.30427, having the least values in three of the validation methods. When used in forecasting, the trend of the moisture content continues to consistently fall within the lower end of the accepted range. The distribution of the predicted values also shows a perfectly normal distribution, showing its effectiveness of the model for forecasting.

In this study, we propose the use of an atmospheric pressure cold plasma generated from dielectric barrier discharge (DBD) as an emerging technology in insect pest management. Series of experiments were conducted to test the effectiveness of such plasmas on the lethality of adult <em>S. oryzae</em> by measuring the mortality rate and examining the biochemical markers that impact the insects. Plasma treatments (24 kV input voltage at frequency of 2.5 or 7.5 kHz) were carried out in He and Ar, used as carrier gases, with exposure time ranging from 30 to 120 s. Results showed a high level of mortality (60–100%) for each treatment, with a better efficiency observed when Ar was used as carrier gas. Furthermore, at the highest repetition frequency (7.5 kHz), equivalent to 60 W of electrical power consumption, the insecticidal efficiency reached 100% insect mortality at only 1 h after a 30 s plasma treatment. The mortality rate appeared to be correlated with a notable decrease in protein content and an increase in catalase enzyme levels within the insects' tissue, indicating that insecticidal mechanisms involve oxidative stress. This study demonstrates that low-energy atmospheric cold plasma has detrimental effects on rice weevils and could be considered a promising tool for pest control in stored food, which will help reduce global dependence on chemical pesticides.</p></div>","PeriodicalId":17019,"journal":{"name":"Journal of Stored Products Research","volume":"108 ","pages":"Article 102394"},"PeriodicalIF":2.7,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141945378","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
