Evaporated Milk For Recipes Ii
If you are going to buy and sell these bottles even semi-seriously the price of annual dues for the Association is well worth the money. Lactose It is the principal and typical carbohydrate of milk known as milk sugar. Glucose galactose and other sugars such as oligosaccharides are also present in traces. Lactose exists in true solution in milk. It is a disaccharide composed of two molecules of monosacharides; glucose and galactose. Lactose is readily fermented by the lactic acid fermenting bacteria producing lactic acid and has significance in milk and milk products. It exists in two isomeric forms designated as α and β forms of which the β form is more soluble than the alpha form in water. Lactose content of cow milk is 4.9 percent. The lactose content of milk is inversely proportional to the ash content of the milk.
Casein May be defined as the major protein which is precipitated at pH 4.6 and is exclusive to milk. It is present in spherical bodies as micelles which vary in size with negative surface charge. The caseins of milk may be sub-divided into five main classes αs1 αs2 β gamma and k-caseins. In milk casein is present in combination with calcium in the form of calcium caseinate or more precisely calcium hyhdrogen caseinate. Whey proteins Are those in the whey fraction after the precipitation of casein at pH 4.6. These are the alpha-lactalbumin beta-lactoglobulin immunoglobulins lactoferrin transferrin proteose-peptone fractions etc. Most of these are globular proteins subject to heat denaturation. α-lactalbumin exists in variants A and B forms and is susceptible to denaturation by unfolding of the tertiary structure. β-lactoglobulin is identical to blood globulin and insoluble in water and is responsible for the transfer of antibodies.
You can reduce your risk by initially setting a limit of $10 rather than $20 but if you are not comfortable with a little risk and taking a small loss of some of the bottles you buy then this is a sub-niche you should avoid. Here are some additional general hints & tips to remember when purchasing these bottles...Never buy a bottle that has any chips or cracks no matter how small or seemingly insignificant. The condition of the Pyro-Glaze design is extremely important - avoid any bottles that have chipped faded or scratched Pyro-Glaze as well. These bottles were to be used and then returned to the dairy where they were cleaned and reused. After extended use and cleaning some developed numerous small scratches to the glass. You should avoid bottles that exhibit severe scratching.
