379 Q. From what is the common starch made?
A. Both the edible and laundry starches are made from a number of materials, such as corn, rice, potatoes, wheat, etc. The starch made from corn is the cheapest.
380 Q. What is the difference between edible and laundry starch?
A. The edible starch is starch that has been purified and then pulverized, while the laundry starch is generally unpurified starch, sold as it comes from the kilns, without having been pulverized.
381 Q. What is the difference between the "Lump," "crystal," and "pearl" laundry starches?
A. The difference between these three starches lies only in their appearance, which is due to the way in which the starch is prepared for the drying kilns and the rate of drying. In this way large or small lumps or long and short "crystals" can be obtainel. When the starch is dried rapidly, it comes from the drying kilns in the form of very small particles and lumps, and is called pearl starch.
382 Q. From what is tapioca made and what are the different forms in which it is sold?
A. Tapioca is made from the starch obtained from the tuberous roots of the cassava plant, also known as manioc, a large shrub growing in the West Indies, South America, Java, the Malay Peninsula, and Florida. The roots, which grow in clusters and resemble somewhat sweet potatoes, are from one to eight inches thick and from one to four feet long. After the roots have been washed, they are grated and reduced to a fine pulp. The starch obtained from this pulp is known as tapioca flour, which, when mixed into dough and baked, forms what is known as
"Flake" tapioca. "Pearl" tapioca is produced by forcing the dough, before it is baked, through a sieve, forming little pellets which are then heated to a high temperature. "Medium" and "Fine" tapioca are determined by the size of the sieve. The "Granulated" tapioca is obtained by grinding the "Flake."
383 Q. What is sago?
A. Sago is an article very similar to tapioca. It is prepared from the starch obtained from the pith found in the stem of several species of palm trees, natives of the East Indies, and is sold in pearled formó"Pearl Sago."
