Citrus oil is a clear volatile oil with a pleasant pungent odor. The material furnished for these experiments was extracted from citrus peel and is double distilled. Citrus peel oil mixed with dehydrated gum turpentine in the proportions of 80 per cent and 20 per cent respectively, has been used commercially as a deodorant and an insect repellant. Because of its penetrating properties citrus oi...

This study was conducted to determine that carrot powder obtain by different drying methods (oven and vacuum-freeze dryer) of carrot unfit for human consumption that whether feed additives in animal nutrition or not. Carrots randomly divided 2 groups. First group was dried by using oven, second group was by using vacuum freeze dryer methods. Dried carrot prepared from fresh carrot was analysed ...

in this research an experiment based on completely randomized design with three replications and 11 treatments was conducted of mentha piperita. treatments consisted of dryer drying, artificial shade drying, oven drying (50 and 70 °c), and microwave drying with different powers (100, 180, 300, 450, 600 and 900 w) and fresh sample as control. the end time of each treatment determined on the basi...

Due to high surface area, low density, open pore structure and excellent insulation properties aerogels were intensively investigated in the past decades for diverse range of applications. The state of the art of aerogel production by supercritical drying is to produce monolithic aerogel, where the sol is aged in molds and dried by extraction with supercritical CO2. Aerogels in form of spherica...

A suitable formulation to improve Lavandin essential oil applicability as biocide has been study in this project. Agrochemical formulations are required to be long-term physical stable and enhance biological performance of the agrochemical. Particle encapsulation of lavandin oil had been considered as possible formulation. Two high pressure spray techniques (PGSS and PGSS drying) had been appli...

Mineral oil (or Hydrocarbon oil) in water samples is determined by liquid-liquid extraction, followed by a clean-up step on Florisil, and GC-FID analysis. Using the Agilent 7696A Sample Prep WorkBench system, drying and clean-up of samples obtained after liquid-liquid extraction can be automated. High recoveries and excellent reproducibility are obtained for the mineral oil fraction, while the ...

The high oil content of the avocado fruit (Persea americana Mill.) has been known since Aztec times, with the fruit sometimes referred to as “vegetable butter” or “butter pear.” The plant originated in Central America, and its cultivation has spread to warm subtropical and temperate climates worldwide. The flesh of an avocado can contain up to 30% oil (based on fresh weight), but there is very ...

OBJECTIVES Microencapsulation of drugs into preformed polymers is commonly achieved through solvent evaporation techniques or spray drying. We compared these encapsulation methods in terms of controlled drug release properties of prepared microparticles and investigated the underlying mechanisms responsible for the 'burst release' effect. METHODS Using two different pH-responsive polymers wit...

7.1 Abstract Tuna oil-in-water emulsions containing droplets stabilized by lecithin-chitosan membranes were produced using a two-stage process. Corn syrup solids were added to the emulsions and then the emulsions were spray dried, which produced a powder consisting of smooth spheroid powder microcapsules (diameter = 5-30 μm) containing small tuna oil droplets (diameter <1 μm) embedded within a ...

Drying is one of the most important stages of hazelnut processing and its optimization improves the quality of the final product. The quality of hazelnut is dependent on chemical and organoleptic characteristics of fruit that is affected in the drying process. In present research, samples of Gerd cultivar of hazelnut (Corylus avellana) were dried in shelled and in-shell forms using a laboratory...
