Food Analysis * Concerned with development of criteria of quality and identity… * Process in w/c sample is treated in a series of steps Importance: 1. It’s necessary in the dev’t and enforcement in standard of identity‚ purity and feel of processed food products. 2. It can provide studies design to improve and control the quality of natural processed food. 3. Can help in the determination of the composition of products in their normal and abnormal storage conditions. Methods

XRD – X-Ray Diffraction X-ray diffraction (XRD) is a powerful non-destructive technique for characterizing crystalline materials. It provides information on structures‚ phases‚ preferred crystal orientations (texture)‚ and other structural parameters‚ such as average grain size‚ crystallinity‚ strain‚ and crystal defects. X-ray diffraction peaks are produced by constructive interference of a monochromatic beam of X-rays scattered at specific angles from each set of lattice planes in a sample. The

Mirrors in Telescopes The human eye cannot detect much light because of the small diameter of the retina‚ so telescopes and microscopes are used to help us see more than what humans are naturally capable of. Lenses and mirrors are the two things that can make a star that is a billion miles away look like it so much closer. Arizona is home to one of largest telescopes in the world‚ the Large Binocular Telescope. It has two twenty-seven foot mirrors to create the best and clearest image for the

Practical 1- An experiment to observe the features of an Onion Cells Method: Gather all equipment that will be used for the experiment and check that they are clean and undamaged. Using forceps‚ peel the membrane from the underside of a small piece of onion. Place the membrane flat on a clean‚ glass slide and add one drop of iodine solution. Use a pin to carefully lower the cover slip over the slide‚ ensure there are no air bubbles before the use of the slide. Set the microscope to its lowest

Compare and contrast the use of light and electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities
