Candy-Making Revolutionized Confectionery from Vegetables There are several different modifications, or forms, of dextrins, depending upon the extent to which the simplification of the starch molecule by hydrolysis is carried. The Chemistry of Plant Life The form now generally accepted is known as dextri-maltose, which is a combination of dextrin and maltose, both of which are readily acted upon by the sugar-splitting enzymes of the digestive juices. Dietetics for Nurses Starch is made from it both for the laundry and for the manufacture of farina, dextrin, etc. Storyology Essays in Folk-Lore, Sea-Lore, and Plant-Lore As glazes and coatings, a variety of substances have been employed, such as butter, margarin, vegetable oils, paraffin, vaseline, gums, dextrin, gelatin, resins, glue, milk, glycerin, salt, sodium bicarbonate, vinegar, Irish moss, isinglass, albumen, etc. All About Coffee By this means the starch is partially converted into dextrose, a sugar, and dextrin, a gum.

Special Report on Diseases of the Horse Their solutions are, as a rule, sticky or gummy in consistency, which suggests that these compounds bear the same relation to inulin that dextrins do to starch. The Chemistry of Plant Life Saliva, the characteristic secretion of this region, contains the enzyme ptyalin which exerts its influence upon the starches and dextrins. Dietetics for Nurses The hydrolytic transformation of starch to dextrins and maltose has been followed in this way, and the methods may serve as a model to which cellulose transformations should be approximated. Researches on Cellulose 1895-1900 They are derived from malted wheat and barley flour, and are composed chiefly of a mixture of dextrins, dextrose, and maltose. The Mother and Her Child Millar, are maltose and glucose, which latter is derived from the hydrolysis of the stable dextrin.

What Philately Teaches A Lecture Delivered before the Section on Philately of the Brooklyn Institute of Arts and Sciences, February 24, 1899 It was formerly believed that by the action of diastase on starch the latter is first converted into a gummy substance termed dextrin, which is then subsequently transformed into a sugar—glucose. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" The other ingredients of commercial glucose, the maltose and dextrin, have of course the same food value as the dextrose, since they are made over into dextrose in the process of digestion. Creative Chemistry Descriptive of Recent Achievements in the Chemical Industries A weighed quantity of the dextrin is dissolved in cold water, filtered from any insoluble starch, and then the glucose determined directly in the clear filtrate by Fehling's solution.

The Project Gutenberg Encyclopedia Volume 1 of 28 For that reason he uses dextrin instead of starch for his carbohydrate and when he wishes to introduce the "B" vitamine it can be done by his method without having to recalculate the carbohydrate component. The Vitamine Manual Although according to their view they were compounds of maltose and dextrin, they had the properties of mixtures of these two substances. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" Since dextrin has less thickening power than starch, the starch mixture would become thinner if cooked for some time with lemon.

Scientific American Supplement, No. 821, September 26, 1891 It would probably be an improvement to use 10 per cent. solutions for many of the dextrins, as they are when low in starch extremely thin. Scientific American Supplement, No. 821, September 26, 1891 Comparison of starch and dextrin for thickening 54.

Scientific American Supplement, No. 821, September 26, 1891 Which has the greater thickening property,—starch or dextrin? School and Home Cooking The behavior of these artificial gums and dextrins on exposure to a warm moist atmosphere can be determined in the same apparatus as described for gums. Scientific American Supplement, No. 821, September 26, 1891 The ashes of most gum substitutes, consisting chiefly of dextrin, are characterized by the high percentage of chlorides they contain, due no doubt to the use of hydrochloric acid in their preparation. Scientific American Supplement, No. 821, September 26, 1891 The real dextrin is determined by inverting a portion of the filtered liquid with HCl, and then determining its reducing power. Scientific American Supplement, No. 821, September 26, 1891 From these experiments, we find that dry heat has changed insoluble starch into a soluble substance called dextrin.
