Radio frequency-assisted hot air drying of pacific white shrimp (Litopenaeus vannamei): drying kinetics, product quality and composition evaluation

ABSTRACT The influence of radio frequency-assisted hot air drying (RFHAD) on the drying kinetics, product quality and composition of Pacific white shrimp was evaluated and compared with radio frequency drying (RFD) and hot air drying (HAD). The results demonstrated that RFHAD showed faster drying rate and also ensured better product quality in terms of texture property, astaxanthin content, color quality, rehydration rate and microstructure of shrimp. Furthermore, RF wave could significantly reduce the formation of bitter amino acids (p < .05) and showed no significant difference in the content of umami amino acid. However, secondary structure changes were observed in RFHAD shrimp with a decrease in β-sheet and α-helix contents and increase in β-reverse fold, and RFHAD noticeably decreased the onset temperature, peak temperature and thermal enthalpy (ΔH) values of shrimp, which showed lower thermal stability. Therefore, the RFHAD method is a fast and efficient drying technology for shrimp with high-quality characteristic.

Epigenetics as a Regulator of Tree Specialized Metabolites In Vitro Production

Specialized metabolites correspond to millions of natural molecules from different chemical families depending on plant taxa that play a key role in ecological interactions during their life cycle. Due to their chemical properties, plants’ specialized metabolites have been exploited for a long time for various industrial applications. However, the limitations in natural population resources as well as the difficulties of their cultivation in terms of production quality or product safety have not always been satisfactory, notably for perennials such as forest trees. Reliable and eco-adapted practices for the production of specialized metabolites such as in vitro cultures provide a useful and powerful alternative to agronomic cultures. Modern omics have allowed the identification of metabolite pathways but have also raised the question of their complex regulation to improve their production. Among the major regulatory players, epigenetics have been shown in recent years to be involved in plant development and the response to environmental variations. Here, the state of the art concerning the epigenetic control of plant specialized metabolite in vitro production as well as the challenges in forest trees are presented.

Using cellular automata to simulate external heat and mass transfer in the wood drying process

This work involves modeling the external heat and mass transfer in the wood drying chamber. One of the remarkable features of this research is to use cellular automata with variable cell sizes closely related to the geometric parameters of the considered wood materials. This approach allows for modeling and analyzing the changes in the characteristics of wood materials during the hydrothermal treatment process, taking into account their unique geometry. Such modeling provides valuable information about how different shapes and sizes of wood react to various drying conditions. This research has significant implications for industries dependent on wood drying, such as construction and furniture production, as it offers an individual approach to upgrading the drying processes of wood materials with different geometries. The modeling in this work is carried out using wood materials, primarily pine, with a standardized thickness of 25 mm and an initial moisture content of 30 %. The modeling is conducted under conditions of moderate drying, accurately mirroring real-world scenarios. Using pine as the researched material aimed to represent a widely used wood species in the industry, thereby increasing the relevance of the results. The work also explores the influence of various parameters of the wood drying agent. To achieve this, three key factors are systematically varied: temperature, relative humidity, and drying agent velocity. Temperature fluctuations are carried out within a range of ±10 °C. Similarly, relative humidity is adjusted within ±10 % of standard technological parameters. Finally, the drying agent velocity was increased to a maximum of 6 m/s. Thus, the impact of these changes on the moisture content in wood materials is investigated. The results obtained can be applied in an industrial setting. The knowledge gained from the experiments can play a crucial role in improving the wood drying process. In summary, the work investigates the hydrothermal treatment of wood materials, shedding light on the critical role of wood drying agent parameters in controlling moisture content in wood materials. The potential advantages in terms of product quality and overall production efficiency cannot be overstated, and it is expected that this work will be a valuable resource for industries dependent on wood processing.

Impact of Agricultural Policies on the Sustainable Greenhouse Development in Biskra Region (Algeria)

Since its appearance in Algerian agriculture, the greenhouse production system has turned the agricultural sector upside down, bringing great advantages for production in terms of quality and quantity, creating a very important socio-economic dynamic, especially in the Saharan region. This paper makes a new contribution by providing information on the impact of agricultural policies on greenhouse development in Biskra (southeastern city in Algeria). This study aims to understand the type of farms/farmers most specialized in greenhouses as well as the relationship between the use of these land acquisition and financing policies (PNDA) and their degree of specialization in greenhouses. A field survey was held from February to April 2021 in the M’ziraa region (a municipality of Biskra City), completing 97 questionnaires. Collected data were analysed by Ordinary Least Squares (OLS) regression and Truncated regression. The results show that farmers who used PNDA to acquire the land and for greenhouse investments and those with a lower education level are less likely to specialize in greenhouse production. Similarly, the effect of farm size is negative on the specialization in greenhouse production. Conversely, we found that farmers who do not directly manage the farm and those who have a longer experience with greenhouse production invest a higher share of their land in greenhouses.

Optimization of iron-based catalyst for partial upgrading of Athabasca Bitumen: The role of Fe oxidation state, particle size, and concentration

The present investigation examines the prospective application of Fe-based catalysts for catalyzing the partial upgrading of Athabasca oil sand bitumen, aiming for developing an economically viable and environmentally sustainable process. The primary focus is to analyze the impact of the oxidation state of iron, catalyst particle size, and catalyst concentration on partial upgrading efficiency to optimize bitumen resource utilization without the need of an external source/supply of hydrogen gas using an autoclave reactor. The experimental results demonstrate that Fe-based catalysts, particularly those with lower oxidation states such as FeS, FeO, and Fe3O4, significantly improve the oil quality and reduce bitumen’s viscosity through increasing saturates and substantially reducing the asphaltene fractions. Furthermore, it is also identified that those catalysts can promote hydrogenation and cracking reactions that transform heavier fractions into lighter ones while achieving up to 59% vacuum residue conversion. A comprehensive screening process using Minitab statistical software was made to identify the best catalyst based on the catalyst’s oxidation state, concentration, and particle size range. As a result, Fe3O4 nanoparticles at a 0.5 wt% loading have been identified as the optimal catalyst combination for achieving the maximum liquid yield, while simultaneously producing the minimum asphaltene content, and maximum viscosity reduction. An assessment of the fresh and spent Fe3O4 catalyst yielded valuable insights concerning the catalytic partial upgrading of bitumen, unveiling a reaction mechanism involving iron catalyst sulfidation, desulfurization reactions, CH scission, and hydrocarbon cracking, in addition to the formation of coke. The potential role of various alloy materials employed in the fabrication of reactors for bitumen partial upgrading has also been studied and compared, discussing their unique advantages and limitations in terms of product quality and liquid yield. The findings presented in this study contribute significantly to the development of more efficient and sustainable upgrading processes, paving the way for optimizing catalyst properties for bitumen upgrading applications and providing a valuable perspective on the role of catalysts in the upgrading of heavy oils.

Purification and characterization of acetylcholinesterase from Hide Beetle (Dermestes maculatus, De gee) larvae

Adult and larvae of Hide Beetle (Dermestes maculatus) are pests of stored animal materials or products rendering them unsuitable both in quantity and quality for consumption. Some chemical insecticides have been known to irreversibly inhibit Acetylcholinesterase (AChE) activities, an enzyme that catalyzes the breakdown of acetylcholine to choline and acetic acid at cholinergic synaptic sites. The aim of this study was to purify and characterize AChE from D. maculatus larvae with a view to evaluate some its biochemical properties. Acetylcholinesterase, purified to apparent homogeneity from the larvae of D. maculatus, was confirmed by SDS-PAGE, its physicochemical and kinetics properties were evaluated. Some chemicals and plant-based inhibitors were used for inhibition studies. Purified AChE from D. maculatus larvae accounted for 4.5% activity remaining with a specific activity of 4.19 mmol/min/mg and has a molecular weight of 42.65 kDa. Its stability at pH range of 8–10 and temperature range of 40–55 °C as well as kinetic values favored breakdown of acetylcholine iodide. From the inhibition patterns, anisaldehyde and α-terpineol inhibited the purified enzyme in similar way to chlorpyrifos and cypermethrin. The inhibition of the purified AChE by chemical and plant-base insecticides in similar manners suggests probable use of plant chemicals as an effective bio-insecticide for the control of Hide Beetle larvae and hence, can be used for an overall improvement of the duration of stored products in terms of quality and quantity.

Investigation of the usage of waste materials and By-Products as grinding aids in calcite grinding

Along with the increasing importance of water worldwide, it is thought that developments in fine grinding processes performed by dry grinding and using grinding aids are too essential to be ignored. Indeed, grinding chemicals in the form of pure or commercial mixtures are intensively used in mineral processing plants in dry grinding systems to micronized sizes, e.g., dry grinding of calcite to micronized sizes. This study investigated the usage of olive pomace oil (OPO) and olive waste water (OWW), waste/by-products of the olive oil industry, as grinding aids in the dry grinding of calcite to micronized sizes using a laboratory-scale stirred ball mill and compared them with pure and commercial grinding aids. The test results were evaluated in terms of product fineness, powder flowability, color factor, surface adsorption characteristics, and agglomeration behavior. The study revealed that using any of the grinding aids tested improved the grinding process in comparison with the no aid condition. It was understood from the experiments and analyses that using OPO and OWW as grinding aids positively affected grinding performance. Particularly, the particle size analyses showed that the product fineness obtained in dry grinding tests was close to that obtained with commercial and pure grinding aids. Considering all the investigated grinding aids (except for OWW), powder flowability increased with the increasing concentration of the grinding aid. Remarkably, the OWW results demonstrated that the increase in dosage was not beneficial in terms of the ffp index. However, the enhancement of particle size was obvious. When evaluated in terms of product quality, four types of grinding aids increased total color differences with respect to feeding material and no aid test. Furthermore, the Fourier transform infrared spectroscopy (FTIR) conducted to determine the interaction between particle surfaces and grinding aids indicated that the grinding aids used in this study were adsorbed on the calcite surfaces by their non-polar, polar functional group and hydroxyl group. The analysis, in which the agglomeration phenomenon was examined with SEM (scanning electron microscopy) images, revealed that using grinding aids reduced the formation of agglomerates in comparison with the no grinding aid condition.
