To quickly assess the difficulty of the text, read a short excerpt:
of clear dilute starch paste in a small beaker and add 2 or 3 cc. of undiluted saliva which has been filtered through coarse filter paper.
Keep at body temperature and from time to time pour off small portions and test with iodine solution, keeping each for comparison. Note the gradual change from blue to red to yellow and finally to colorless. When this stage is reached, add a small portion of the material to Fehling's solution, boil, and note reduction due to maltose.
114 HOUSKHOLD CHEMISTRY ...2. To 25 cc. of dilute starch paste add about 5 cc. of diastase solution and keep at 55°. Test portions from time to time with iodine until the test fails to give a color (maltose). At this stage boil the remainder of the solution with about 25 drops of dilute sulphuric acid for 10 minutes. Neutralize and test this with Fehling's solution for glucose.
Dextrin.
The dextrins are colloidal compounds, soluble in water, and precipitated by strong alcohol. As starch hydrolysis proceeds a number of dextrins are formed : the dextrin which gives a red-brown color with iodine is termed erythrodextrin ; that which is forming as iodine ceases to act is achroodextrin.
