Sweetened Condensed Milk I
Because of this the value of individual bottles can range from only $10 to $500 and even higher. Additionally due of the vast variety of bottles produced it has been impossible for anyone to really do the research to determine values for them all. Due to this factor if you are interested in this sub-niche it is necessary that you be willing to take somewhat of a shotgun approach that involves some risk and this should be considered before making a final decision The only ones you should initially consider will have ALL the following characteristics If even one of these six requirements is not there do not even consider the bottle unless you are very knowledgeable about collectible milk bottles. They must be 1 quart in size They must have a round body They must be at least 8? tall They must have both a town and state name on them They must have a dairy creamery or farm name on them These town state and dairy names must be in colored (Pyro) graphics Here is how I have been buying them for the past several years.I buy any milk bottle that meets the previously mentioned six requirements if I can buy it for $20 or less.
Milk fat varies in amount and composition according to the breed species feed and lactation time of which feed being a major factor. Fat is distributed in globules as triglycerides (98-99 %) fat globule membrane in combination with phoshpholipids and lipoprotein (0.2 to 1.0 %) and also as free fatty acids cholesterol and phospholipids in the serum. Phospholipids These contain phosphorus in their molecules in addition to the fatty acids and glycerol; they also contain a nitrogenous base. Principally milk phospholipids are the Lecithin Cephalin and Sphingomyelin. Though fat-soluble they are hydrophilic and imbibe large quantity of water and swell. They are used as antioxidants for fat rich dairy products. Vitamins Various vitamins present in milk are as follows.
Normal milk contains 0.1% whereas colostrum contains 6 %. Milk fat The digestibility of milk is comparatively higher than other oils and fats. This can be attributed to existence of fat globules in aqueous phase forming an emulsion. This facilitates its easy absorption through the intestinal tract when compared to other fats which have to be emulsified with bile salts enzymes from pancreas and fat splitting lipases. Endowed with short and medium chain fatty acids milk fat can be easily absorbed when compared to long chain fatty acids because of the ability of the lipases to split the ester bonds in the former. Supplementation of milk fat in the diet increases the energy density. When compared to human milk the cow milk is low in essential fatty acids such as linoleic and linolenic acids.
Do not let the fact that a bottle is from a state that is known as a diary state dissuade you from buying it. Many of the bottles from these states are rare and command high prices. Bottles with more than one color will usually bring higher prices. Bottles with attractive graphics on their reverse side will often bring higher prices things such as babies; war related themes patriotic themes and herds of cows are just a few things to be on the lookout for. A word of caution In the last several years reproductions of some milk bottles have begun to appear more and more. Fortunately the vast majority of reproductions are of other types of milk bottles but there are reproductions of 1 quart Pyro-Glaze milk bottle as well.
