NOTES ON FOOD PRESERVATION & PACKAGING FOR MSc STUDENTS By Prof C S Purushothaman – Feb 2013 HURDLE TECHNOLOGY The spoilage and poisoning of foods by micrnorgenisms is a problem that is not yet under adequate control‚ despite the range of preservation techniques available (e.g. freezing‚ blanching‚ pasteurizing and canning). In fact‚ the current Consumer demand for more natural and fresh-like foods‚ which urges food manufacturers to use only mild preservation techniques (e.g. refrigeration‚ modifed-atmosphere

crops etc that need to work on. Key words: Aquponics ‚ polyhouse cultivation‚ Ammonia(NH4) ‚ Nitrite(NO2) ‚ Nitrate(NO3). Introduction: Aquaponics is‚ farming technique in which water from aquaculture is used to grow crops and extra water returns back to the fish tank. When this water circulated near root zone‚ nitrogen fixing bacteria (manly nitrosomonas and nitrobactor) convert ammonia (NH4) into nitrite (NO2) and then to nitrate (NO3) form. By these‚ plants get nutrients as fertilizer and nitrates

Water is determined by the amounts and kind of suspended and dissolved substances in the water‚ degree of alkalinity (pH)‚ temperature‚ colour and smell‚ and the company of undesirable microorganisms. In this experiment‚ we are explaining whether bottled water is more pure than tap water. For this experiment‚ hypothesis is which water is more pure bottled or taps water. To test the experiment we have used the equipment like bottled water‚ tap water and water test kit. In the research‚ it has been

Option F: Microbes and Biotechnology Diversity of Microbe F.1.1 Outline the classification of living organisms into three domains. Three domains of living organisms: 1. Archaea - very primitive; live in extreme habitats 2. Eubacteria - more advanced 3. Eukaryota - all life forms with eukaryotic cells (have a nucleus) Use of ribosomal RNA sequences for classification rRNA is found in all cells rRNA is easy to isolate Analyzed to determine the exact sequence of nucleotide bases

CYCLES IN BIOLOGY This essay will give examples of cycles in biology from different scales of magnification‚ ranging from molecular level to populations and ecosystems. Cycles are sequences of events which repeat themselves in the same order‚ one event leading to the next. There are many examples of these in Biology. Cycles can be seen even at a molecular level in the body. An example of this would include the passage of action potentials down neurones in the nervous system. When the cell membrane

Bad eating habits are common. It is easy to operate on automatic when it comes to food. Living in a fast-paced society often makes it so you have to eat on the run‚ skip meals‚ eat whatever is fast and easy or use food to relieve stress. We eat a lot of bad foods everyday‚ but we don’t think what impact on our health it makes. I watch a video about Top 10 Bad Foods and now I can say which products and drinks disappear forever from my diet. So Top 10 Bad Foods are : 1. Soda 2. Doughnuts
