Every Step in Canning The lactic acid group of organisms disappear quite rapidly; the spore-bearing species remaining for a somewhat longer time. Outlines of Dairy Bacteriology, 8th edition A Concise Manual for the Use of Students in Dairying This organism has the power of transforming milk sugar and other saccharoses into lactic acid, with evolution of carbonic acid gas. Scientific American Supplement, No. 530, February 27, 1886 The result of the fermentation in this case is the production of lactic acid, which makes the milk sour. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables According to Mitscherlich, the combination with the proteine or albuminous substance is not a permanent one, but suffers a decomposition by various acids, as dilute acetic and lactic acid. Scientific American Supplement, No. 385, May 19, 1883 The vital factor in preserving the material by this method is the lactic acid which develops in fermentation.

Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables Even if the milk is kept cold, bacterial growth will soon take place, but it will perhaps not be lactic acid bacteria. Maintaining Health Formerly Health and Efficiency When you have made this test and discovered that the bubbling has ceased, then it is time to protect the food from all organisms which destroy lactic acid. Every Step in Canning Thus the bacteria lactis act upon the milk sugar present in milk, and convert it into lactic acid, thus bringing about the souring of milk. A Practical Physiology Its acidity is probably due to muriatic or lactic acid—the acid of sour milk. Hygienic Physiology : with Special Reference to the Use of Alcoholic Drinks and Narcotics Whey is composed of water, minerals, and milk sugar or lactic acid, and is the least valuable part of the milk. Woman's Institute Library of Cookery Volume 2: Milk, Butter and Cheese; Eggs; Vegetables These ferments have as their basis the lactic acid bacteria, and if the manufacturers wish to call their germs by other names, such as Bacillus Bulgaricus, no harm is done. Maintaining Health Formerly Health and Efficiency Hence lactic acid acts in a very peculiar manner, causing inflection at an extraordinarily slow rate, and being highly poisonous. Insectivorous Plants This is due to the fact that lactose undergoes the lactic acid fermentation. A Practical Physiology Nor, again, does the mere presence of lactic acid necessarily imply the presence of lactic ferment. The Harvard Classics Volume 38 Scientific Papers (Physiology, Medicine, Surgery, Geology) At the present time the only method we have for the manufacture of lactic acid is dependent upon bacteria. The Story of Germ Life Do not use metal dishes, for the lactic acid acts upon various metals.

The Story of the Soil; from the Basis of Absolute Science and Real Life, The lactose is converted into lactic acid by means of a special ferment. A Practical Physiology Likewise sweet milk becomes sour, with the formation of lactic acid. The Farm That Won't Wear Out The lactic-acid organisms affect the milk sugar and produce lactic acid; others act upon the fat, producing slight changes therein; while others act upon the casein and the albumens of the milk. The Story of Germ Life It does not form big, tough curds in the stomach, it is easy to digest, and the lactic acid helps to keep the alimentary tract sweet. Maintaining Health Formerly Health and Efficiency The resulting wine, a curious mixture of alcohol, sugar, lactic acid, and water, is most unpalatable, sour, uninviting, and unwholesome. besides ruining the name of Australian wine when sold as such. The Art of Living in Australia ; together with three hundred Australian cookery recipes and accessory kitchen information by Mrs. H. Wicken Or various forms of lactic acid fermented milk may be successful. Disturbances of the Heart Even a weak acid, as the lactic acid of sour milk, sets this free, and thus causes the dough to rise. An Introduction to Chemical Science The manufacture of lactic acid is an industry of less extent than that of acetic acid, and yet it is one which has some considerable commercial importance. The Story of Germ Life The lactic acid seems to be quite beneficial. Maintaining Health Formerly Health and Efficiency The lactic acid in sour milk is a direct antidote to the poison of erysipelas. The Royal Road to Health Intestinal antisepsis may be attained more or less successfully by the administration of yeast or of lactic acid ferments together with suitable diet. Disturbances of the Heart Lactic Fermentation changes the sugar of milk, lactose, to lactic acid, i.e. sour milk. An Introduction to Chemical Science There are several different kinds of lactic acid. The Story of Germ Life Metchnikoff thought for a while that he had discovered how to ward off decay and old age by means of the lactic acid bacteria in milk. Maintaining Health Formerly Health and Efficiency When the milk has attained a certain degree of acidity, the lactic acid bacteria are unable to thrive and the souring process is slowed up and finally stopped. Maintaining Health Formerly Health and Efficiency Most of the other bacteria in milk perish when lactic acid is formed. Maintaining Health Formerly Health and Efficiency When milk is allowed to stand for a while the sugar ferments, through the action of the lactic acid bacteria. Maintaining Health Formerly Health and Efficiency It is due to the action of certain of the milk bacteria upon the milk sugar which converts it into lactic acid, and this acid gives the sour taste and curdles the milk. The Story of Germ Life If this step in digestion is performed by the acid in the fruit no more harm is done than when it is performed by the lactic acid bacteria. Maintaining Health Formerly Health and Efficiency The sugar is turned into lactic acid, which combines with the casein and when this process has continued for a certain length of time the result is clabbered milk or sour milk. Maintaining Health Formerly Health and Efficiency The lactic acid seems to have a sweetening effect on the alimentary tract.
