The long-term availability of cassava ferment and the production of attieke of healthy and consistent quality are becoming serious problems in Côte d’Ivoire. The overall objective of this work was to assess the effect of several drying techniques on the performance of the traditional cassava ferment with a view to establishing a stabilized ferment for the production of attieke in Côte d’Ivoire. To do this, three drying techniques were used, namely, oven drying, sun drying, and freeze-drying. The end of the drying process is marked by the stabilization of the humidity rate of the ferment. The results obtained during the drying process indicate that the sun-dried ferment contains more GAM (1.2 ± 0.2) × 108 CFU/g than the other dried ferments. The freeze-dried ferment has the highest load of lactic acid bacteria (3 ± 0.2) × 105 CFU/g, while Bacillus was observed in large numbers in the ferment dried at 45°C (7.1 ± 0.6) × 105 CFU/g. The 37°C dried and freeze-dried cassava ferments recorded high yeast loads of (7.6 ± 0.5) × 104 CFU/g and (7 ± 0.4) × 104 CFU/g, respectively. Moulds ((5 ± 0.2) 1 × 102 CFU/g) were only detected in the 37°C dried culture. Moreover, during the fermentation of the cassava dough with the different ferments obtained after drying, a significant acidification occurs in the dough inoculated with the freeze-dried ferment (2.9 ± 0.07%). However, the attieke produced with the freeze-dried ferment and the ferment dried at 37°C was the most appreciated by the panelists. Thus, freeze-drying and oven drying at 37°C are simple alternatives to the use of traditional ferments that can ensure their stability and the conservation of the cassava ferment over a long period of time.

Drying of flowers is the method of maintenance of flowers or removing water and moisture. Dehydration is most important for getting dry flowers. There are Many different types of methods use for removing moisture contain from flowers are air drying, embedded (sand, borax, silica gel, and other materials) press drying, freeze drying, microwave oven drying, hot air oven drying, Glycerin drying, freeze drying. Chrysanthemum is one of the most widely cultivated garden flowers and ranks popularity. The Chrysanthemum flower has fully double flowers with flat petals and the central disc is generally absent. Many of the commonly grown marigolds are cultivars of African and French marigolds. Flower petals of African marigold are the best source of carotene for coloring foodstuffs. From the dried flowers varied manufacture are made and use like petal embedded handmade paper, press dried flower products, candle making, pot pourri, floral jewelry etc. This dried plants and flowers materials also used in industry. For chrysanthemum embedded drying is the best in which flower shape, size, structure, colour are maintained and for marigold microwave and air drying techniques are best in size, colour, shape, colour are maintained.

The present study investigated a novel extended release system of promethazine hydrochloride (PHC) with acrylic polymers Eudragit RL100 and Eudragit S100 in different weight ratios (1:1 and 1: 5), and in combination (0.5+1.5), using freeze-drying and spray-drying techniques. Solid dispersions were characterized by Fourier-transformed infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), Powder X-ray diffractometry (PXRD), Nuclear magnetic resonance (NMR), Scanning electron microscopy (SEM), as well as solubility and in vitro dissolution studies in 0.1 N HCl (pH 1.2), double-distilled water and phosphate buffer (pH 7.4). Adsorption tests from drug solution to solid polymers were also performed. A selected solid dispersion system was developed into capsule dosage form and evaluated for in vitro dissolution studies. The progressive disappearance of drug peaks in thermotropic profiles of spray-dried dispersions were related to increasing amount of polymers, while SEM studies suggested homogenous dispersion of drug in polymer. Eudragit RL100 had a greater adsorptive capacity than Eudragit S100, and thus its combination in (0.5+1.5) for S100 and RL 100 exhibited a higher dissolution rate with 97.14% drug release for twelve hours. Among different formulations, capsules prepared by combination of acrylic polymers using spray-drying (1:0.5 + 1.5) displayed extended release of drug for twelve hours with 96.87% release followed by zero order kinetics (r²= 0.9986).

Supercritical Co2 Drying

Studies on the influence of drying processes on cellulose nanofiber (CNF) aerogel performance has always been a great challenge. In this study, CNF aerogels were prepared via two different drying techniques. The CNF solution was prepared via existing chemical methods, and the resultant aerogel was fabricated through supercritical CO2 drying and liquid nitrogen freeze-drying techniques. The microstructure, shrinkage, specific surface area, pore volume, density, compression strength, and isothermal desorption curves of CNF aerogel were characterized. The aerogel obtained from the liquid nitrogen freeze-drying method showed a relatively higher shrinkage, higher compression strength, lower specific surface area, higher pore volume, and higher density. The N2 adsorption capacity and pore diameter of the aerogel obtained via the liquid nitrogen freeze-drying method were lower than the aerogel that underwent supercritical CO2 drying. However, the structures of CNF aerogels obtained from these two drying methods were extremely similar.
