The major challenges for industrial commercialized biodiesel production from microalgae are the high cost of downstream processing such as dewatering and drying, utilization of large volumes of solvent and laborious extraction processes. In order to address these issues the microwave irradiation method was used to produce biodiesel directly from wet microalgae biomass. This alternative method o...

Abstract In this work, the advantages and disadvantages of freeze drying microwave were considered analyzed. Experimental data on plums are given. The chemical composition before after freeze-drying was results moisture change, compared.

Plants of the Allium genus produce sulphur compounds that give them a characteristic (alliaceous) flavour and mediate for their medicinal use. In this study, the chemical composition and antimicrobial properties of Allium cepa red cv. and A. sativum in the context of three different drying processes were assessed using metabolomics. Bulbs were dried using either microwave, air drying, or freeze...

Seasonal variations on the content of harpagoside in Scrophularia scorodonia L. (Scrophulariaceae) were investigated using plants collected monthly from January to December in 1995. During growth of this species the percentage of harpagoside was the highest during the maximum development of the plant, specially in July. Harpagoside levels differed among leaves, stems and flowers of S. scorodoni...

• Ethanol was the best solvent to defat T. molitor . Bar with defatted could have legal claim of ‘high in protein’. Oven-dried insects associated negative odor/flavor attributes. Microwave-drying led better liking and sensory profile than oven-drying. Defatting hindered attributes increased liking. It is necessary develop products desirable properties order increase acceptance insect-based by W...

Drying is one of the methods used for preserving fruits and vegetables. However, due to lengthy process elevated temperature convective drying, other pretreatment drying are studied shorten time obtain high-quality products. This study aimed examine effect ultrasonic (US) microwave–hot air (MW–HA) on time, specific energy (SEC), qualitative properties (e.g., color, shrinkage, rehydration ratio)...

Microwaves have been widely used in the treatment of materials, such as heating, drying, and sterilization. However, the heating in the commonly used microwave applicators is usually uneven. In this paper, a novel multi-material turntable structure is creatively proposed to improve the temperature uniformity in microwave ovens. Three customized turntables consisting of polyethylene (PE) and alu...
