Guar Foaming Albumin – A Foam Stabilizer

Hydrocolloids as emulsifiers and emulsion stabilizers

We consider the essential molecular features of hydrocolloids having the ability to act as emulsifying agents and emulsion stabilizing agents. The criteria for effectiveness in protecting newly formed droplets against flocculation and coalescence are contrasted with the requirements to maintain long-term stability against aggregation, creaming and Ostwald ripening. To illustrate various aspects...

Synthetic particles as contaminants in German beers.

A total of 24 German beer brands was analysed for the contents of microplastic fibres, fragments and granular material. In all cases contamination was found. Counts ranged from 2 to 79 fibres L(-1), from 12 to 109 fragments L(-1) and from 2 to 66 granules L(-1). The results show a high variability between individual samples and samples from different production dates. Possible sources of this c...

Technology update: Understanding hydrocolloids

Historically, many materials have been used in the treatment of wounds, ranging from grease-soaked bandages to what can best be described as sophisticated cloth. The treatment of wounds has traditionally been the remit of surgeons or doctors, but over the past century that remit has expanded to include nurses. Modern medicine sees a more multidisciplinary approach to care as the treatment of wo...

At a time when such ideas as his were regarded as almost too progressive, and, in some quarters indeed, as subversive and revolutionary, he, a recovered patient, demonstrated the value of indivi...
