Edible flowers have been used in the food and beverage industries because of their high nutritional value, flavor, scent. For storage edible these industries, drying is a necessity to store materials more easily prevent damage metabolites flowers. However, may affect metabolite retention conditions can differ according various methods. In this study, Agastache rugosa were dried using four diffe...

Abstract Centella asiatica L. Urban (CA) is a valuable medicinal herb that contains various bioactive secondary metabolites. In the present study, harvested CA was divided into whole plant and leaf parts, were heated-air-dried or freeze-dried. The dried extracted under extraction conditions to obtain 16 extracts, their antioxidant activities examined. Twelve types of metabolites (five polypheno...

In 1890 Alt man dried pieces of frozen tissue by placing ¡hem in a vacuum desiccator at —20 °C. Since then the freeze drying technique has been constantly improved. In ¡939 the freeze drying process was placed for the first time on an engineering basis, and 1940 saw the large-scale production of dried plasma for wartime use. The first book unfreeze drying by Flosdorfin 1949 was followed by the ...

A new type of freeze-drying microscope based upon time-domain optical coherence tomography is presented here (OCT-FDM). The microscope allows for real-time, in situ 3D imaging of pharmaceutical formulations in vials relevant for manufacturing processes with a lateral resolution of <7 μm and an axial resolution of <5 μm. Correlation of volumetric structural imaging with product temperature measu...

Decellularized arterial scaffolds have achieved success in advancing toward clinical use as vascular grafts. However, concerns remain regarding long-term preservation and sterilization of these scaffolds. Freeze drying offers a means of overcoming these concerns. In this study, we investigated the effects of various freeze-drying protocols on decellularized porcine carotid arteries and conseque...

The aim of this study was to develop a freeze-drying protocol facilitating successful processing of plant material containing the small surface antigen of hepatitis B virus (S-HBsAg) while preserving its VLP structure and immunogenicity. Freeze-drying of the antigen in lettuce leaf tissue, without any isolation or purification step, was investigated. Each process step was consecutively evaluate...

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...
