An oleaginous fraction obtained from an alcohol extract of the fruit of Pterodon pubescens Benth. (FHPp) was microencapsulated in polymeric systems. These systems were developed using a complex coacervation method and consisted of alginate/medium-molecular-weight chitosan (F1-MC), alginate/ chitosan with greater than 75% deacetylation (F2-MC), and alginate/low-molecular-weight chitosan (F3-MC)....

The objective of this work was to evaluate the influence of inlet air temperature and emulsion composition (total solid content and oil concentration), as well as its associated properties (viscosity and droplet size), on the microencapsulation of flaxseed oil by spray drying, using gum Arabic as wall material. Coarse emulsions were prepared by blending the flaxseed oil and the gum Arabic solut...

Diabetes mellitus (diabetes) is suffered by more than 180 million people and is responsible for approximately 2.9 million deaths each year. This mortality rate is expected to increase by 50 % in the next decade. Due to the inconvenience of the traditional treatment of diabetes by subcutaneous administration of insulin injection, various attempts are made in the production, purification, formula...

Microencapsulation of plant-beneficial bacteria for use as biopesticides is a growing area interest in the search alternatives to harmful chemical pesticides. In this study, we assessed microencapsulation Gram-negative, non-spore-forming bacterial strain Collimonas arenae Cal35 novel cross-linked alginate microcapsules (CLAMs) formed by spray-drying, and matrix shell (CLAMshell) particles fluid...

1 In the past few years, considerable advances of basic and application researches have taken place in the field of pharmaceutics. The newly recognized research thrust on nanoand microencapsulation is expected to have a revolutionary impact on the human health. To do this, considerable interest has been devoted towards the design of new drug delivery systems with the aim to specifically target ...

Freestanding protein films are interesting for many applications ranging from microencapsulation to tissue engineering. Here, the authors use interfacial rheology to characterize the adsorption kinetics and the rheology of spider-silk films formed at an oil water interface. The high surface activity of the engineered spider-silk proteins results in a fast formation of highly stable films, which...

There has been considerable interest in the biological functions of astaxanthin and its potential applications in the nutraceutical, cosmetics, food, and feed industries in recent years. However, the unstable structure of astaxanthin considerably limits its application. Therefore, this study reports the encapsulation of astaxanthin in calcium alginate beads using the extrusion method to improve...

The objective of this work is to develop a novel coacervation process to produce microcapsules of polylactide (PLA) to encapsulate thyme oil that will be used in cosmetics. The novelty of this approach consists of dissolving PLA in dimethylformamide (DMF) which is a good solvent for PLA but in addition has high solubility in water. Upon contact with water, the homogeneous solution of PLA in DMF...

The objectives of this work were to develop a new technique for lycopene microencapsulation by spray drying using dehumidified air as drying medium and to determine optimum operating conditions. A two-step optimization procedure was used. The encapsulation variables were selected in accordance with the PlackettBurman experimental design and were further optimized via response surface methodolog...

Cyclodextrins are used to improve stability of flavor and/or oil via encapsulation of certain specific ingredients that exist by nature in food materials. The method is called often as “molecular encapsulation”, because the ingredients are encapsulated in the molecular cavity of cyclodextrins. Cyclodextrins form inclusion complexes with a variety of molecules including flavors, fats and colors....
