Baseline Buttermilk Alternative The Milk Choosing The Right Milk Alternative
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.
Short and medium chain fatty acids with 4-12 carbon atoms which occur at comparatively higher concentration in milk fat reported to have antibacterial and fungistatic activity. Milk fat plays another important role in preventing tooth decay by forming a protective coat over the surface of enamel. It is composed of triglycerides of fatty acids. A fatty acid molecule is composed of hydrocarbon chain and carboxyl group. Triglycerides are of two types simple and complex. In simple all the three fatty acids are of same nature whereas complex triglycerides on hydrolysis give glycerol and different fatty acids. The milk fat exists in the form of small globules of sizes ranging from 2 to 10 microns with different glycerides of low melting points in suspension.
You can find some good information regarding how to identify reproductions along with some pictures of known reproductions from various online sources. If you are interested in learning more about these bottles there are two books currently available that provide some excellent information about how they were made and used along with some basic pricing information. The book are titled "Udderly Beautiful" and "Udderly Splendid" by John Tutton. Both give some rarity and pricing information but because of the large number of bottles produced they don t cover even a small fraction of the bottles produced. Both can be found for sale on either eBay Amazon or in some antique shops. Other sources of information are The National Association Of Milk Bottle Collectors and the individual web sites many of their members maintain.
