This is true particularly in those samples which show extensive multiplication of the psychrotropic species. If the blue color of the sampled milk disappeared over the test period, it was likely that bacteria were consuming oxygen, and the milk had not been pasteurized properly. This will avoid stagnation and maintain lactation. The accuracy of the test i s increased, reduction time shortened and decolorization more uniform if the samples are periodically inverted during incubation. Record reduction time in whole hours between last inversion and decolorization. Decolorization is considered complete when four-fifths of the color has disappeared. From: Atherton, H. V. and Newlander, J. MATERIALS : NaOH solution with a known titre (0.4 N) Becker Burette with sensibility 0.1ml and 50 ml capacity with its support 250 ml of fresh milk phenolphthalein METHODOLOGY: We rinse the burette with titrant (NaOH), we take a known quantity of milk and we add the indicator (phenophthalein).

Light hastens reduction and therefore the tests should be kept covered. Milk of a greenish tint, which in addition is accompanied by a blood inclusion, can occur with a strong rush of fluid. Cold milk holds more oxygen than warm milk; pouring milk back and forth from one container to another increases the amount, and at milking time much oxygen may be absorbed. This can happen if the feeding regimen is violated. Measure 1 ml of the methylene blue thiocyanate solution into a test tube. In the summer, milk becomes non-greasy, which is directly related to the need of newborns for additional fluid. The resazurin test is conducted similar to the methylene blue reduction test with the judgement of quality based either on the color produced after a stated period of incubation or on the time required to reduce the dye to a given end-point. It is worth noting that milk in this case does not pose any danger to the baby. Breast milk is a unique nutritious product that can change its smell along with color and taste at different periods of lactation. Color, an aspect of the appearance of food, is a key indicator of quality.

Tubes are examined and classified at the end of an hour in the "one-hour test" or at the end of three successive hourly intervals in the "triplereading test." Nearly every liquid is either acidic or basic in nature.Acids are molecules that release hydrogen ions (H+) when dissolved in water.Bases release hydroxide ions (OH-).The pH scale is a way of measuring and precisely specifying how acidic or basic a solution is. Transitional milk of the mother appears immediately after the production of colostrum, which occurs even in the process of carrying the baby. They should be certified by the Commission on Standardization of Biological Stains. Thermoduric and psychrotrophic bacteria reduce methylene blue very slowly if at all.
