Lactic
acid bacteria - their uses in food
-
Lactic acid bacteria have been used to ferment or culture
foods for at least 4000 years. They are used in particular in fermented milk
products from all over the world, including yoghurt, cheese, butter,
buttermilk, kefir and koumiss.
Campylobacter Jejuni - A Lesser Known Bacteria -
Campylobacter jejuni has
been taken seriously as a food pathogen only since the 1970's, but it is
probably responsible for maybe twice as many cases of reported enteritis
than the better known Salmonella.
Foods
Under the Microscope
- This website provides links to various subjects on food
microscopy, most of which are based at the University of Lund in Sweden.
Sections contain the detailed chemistry of various dairy products including
structure, composition and behaviour. The site was originally compiled by
Miloslav Kalab.

Basic
Concepts of Optical Microscopy
- A comprehensive primer on the basic optical microscope, as well as the
electron, confocal, polarizing, and stereoscopic microscopes. Virtual
microscopes allow the user to simulate the use of a variety of real-life
microscopes. There are galleries of photomicrographs illustrating a variety
of specimens. This website provides complete instructional materials on the
theory of light and the applications of microscopy to a variety of
analytical problems.
