Composites were produced in the presence of simulated body fluid (SBF) at pH 7.4 and 37 °C implementing tannic acid (TA) as a cross-linking agent. HAp-GEL composites were characterized by X-ray diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy and scanning electron microscopy. 5-FU was loaded on HAp-GEL composites via spray dryer through encapsulation. Drug release kinetics studies revealed that 5-FU release from HAp-GEL composites were best fitted to first order kinetic model with R2 values in the range of 0.85–0.98. Gelatin and TA contents of the composites were found to affect the release profiles and initial burst values, with higher initial burst values at greater gelatin contents. pH dependent release of 5-FU was observed from produced HAp-GEL composites with higher release at physiological pH (7.4) conditions. Current study suggest that produced 5-FU loaded HAp-GEL composites hold potential as carrier for 5-FU drug in clinical applications.Keywords: Hydroxyapatitegelatintannic acidpolymercomposite Disclosure statementThe authors report no conflicts of interest.

The freeze-dried fermented milk powder with protectants demonstrated good flow and rehydration properties with 0.98 flow stability, 4350 g/mm cake strength, 4.45 mm cohesion index, and 89% dispersibility. The freeze-dried fermented milk powder displayed a type III isotherm curve with a predicted shelf-life of 33.7 and 46.3 days in aluminum polyethylene and 4-ply retortable polypropylene–polyamide–aluminum–polyethylene terephthalate, respectively, at 38 °C and 90% RH.

No specific Computer Aided Engineering (CAE) tool is available to assist in the design of cassava drying equipment. In this study, a convective-diffusive model was selected in the literature for its genericity and suitability for engineering purposes. Three drying kinetics were sufficient to identify the required temperature-dependent effective diffusivity. They were measured under 40–80°C air, flowing perpendicular to the cassava cylinders. For validation, a total of 36 kinetics were measured on four cassava products of different origins, levels of transformation, geometries, dried in air flows at 40–80°C, parallel or perpendicular to the product layer. Using 3 properties taken from the literature and few straightforward lab measurements, the model was able to accurately predict (RMSE: 0.04 d.b.) all drying kinetics for cassava products from flour to root cuts.Keywords: Dryingsimulationdiffusivitycassava AcknowledgmentsThe authors thank Dr. Jean-Michel Méot for his advice and his expertise.

A microwave intermittent vacuum drying scheme (MIVD), microwave vacuum drying power curves control scheme (MVD-T), and microwave vacuum drying power curves with intermittent control scheme (MIVD-T) were developed and conducted. As shown, temperatures under control schemes were all kept at more moderate ranges compared to constant power, where MIVD-T showed less fluctuation by adopting power curve changing with time as input variable. It was found that temperature control schemes could improve the appearance, as MVD-T and MIVD-T both reduced carbonization on the exterior and interior of raspberries. For antioxidant properties, there were differences between different schemes, in which MIVD-T could maintain more total monomeric anthocyanin (TMA) compounds and keep other antioxidant compounds similar to other drying methods. Control schemes such as MIVD, MVD-T, and MIVD-T were effective in obtaining more steady temperature materials than conventional microwave vacuum drying and were beneficial for drying quality.","PeriodicalId":11374,"journal":{"name":"Drying Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135878033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With an aqueous ethanol solution, the water vapor in the drying gas dissolves in the liquid phase on the material surface, and the gas-liquid equilibrium governs the drying characteristics. With n-hexane, the water vapor in the drying gas condenses on the surface of the drying material.

This includes many technologies that are already commercialized or show the potential for imminent industrial exploitation. In the near future, it will be essential to ensure net or near net zero emissions of greenhouse gases, which means any carbon emissions created are balanced by taking the same amount of carbon out of the atmosphere. Biomass has historically been widely used in many drying applications. In recent years, it has been converted into biogas or liquid biofuels. Further, biofuels are being derived from non-edible vegetable oils, so as not to interfere with the food chain and concerns over food insecurity. Alcohols can be made from sugar or sugarcontaining materials, starch or starch-containing materials, and also lignocellulosic biomass. Biodiesel can be obtained from various edible and non-edible oils, seeds of various crops and also from algae, fungi and lignocellulosic biomass. Dimethyl ether, which is a synthetic future fuel, can be obtained from lignocellulosic biomass and can be blended with diesel for use in vehicles. Such renewable fuels are a good option to replace fossil fuels as the source of thermal energy for industrial drying. Renewable fuels such as hydrogen, compressed air and synthetic methanol have a large potential to provide sustainable energy for drying. Methane is a powerful greenhouse gas, but it is a good fuel, which can be obtained both from renewable and nonrenewable sources. Renewable methane can be obtained from a number of routes: (i) anaerobic decay/biological or chemical processes (ii) thermal gasification of organic materials and (iii) landfills generally from municipal solid wastes. The dry mass of biological materials cycling in the biosphere is about 250� 10 ton/year, incorporating about 100� 10 ton/year of carbon. The associated energy bound in photosynthesis is 0.634� 10 kW. Of this, about 0.5% by weight of biomass is used as crops for human food. Biomass provides about 13% of mankind’s energy consumption, including much for domestic use in developing countries, but also significant amounts in developed economies. Carbon released from the burning of biomass is neutralized via photosynthesis, which generates energy from biomass and is ‘carbon neutral.’ Approximately one out of every nine people in the world is undernourished. Worldwide, approximately 1.3 billion tons of food meant for human consumption is lost for diverse reasons on a yearly basis. This is equivalent to 32.5% of the total production. To address this challenge, several technologies and methods have been developed. Although there are numerous mechanical, electrical and natural convection methods of drying, for small-scale farmers in the developing world, the use of passive solar dryers is a viable option,","PeriodicalId":11374,"journal":{"name":"Drying Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136362311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

FLB is slightly soluble in water; it dissolves slowly and has a low oral bioavailability. FLB-loaded polymeric nanoparticles were produced by solvent evaporation and Spray drying technology. In this research, nanoparticle formulation was prepared by screening and optimization by approaching two different statistical methods (Plackett-Burman and Central composite Designs). The polymeric nanoparticles were evaluated for various characteristics, including drug release, percentage of encapsulation efficiency, X-ray diffraction (X-RD), surface morphology, and Fourier transform infrared (FTIR) spectroscopy. Based on the X-RD analysis, it was found that the drug was successfully incorporated into the polymeric nanoparticles. As a result of nanoparticles containing FLB, % Drug release values were found to be nearly 85-90% increased while % EE was observed in the range of 79-89%. An excellent sustained release, i.e., 14 h, is possible by combining Ethylcellulose (EC) and Eudragit L 100 (ED-100) polymers.
