NFS200 Shortenings
What is shortening?
A fat used for cooking. Can be made from animal, vegetable or compound manufactured substances (Primarily vegetables hydrogenated to be solids)
Margarine in the diet
A source of Vitamin A and/or D Low in saturated fat Cholesterol free Can be classified as a functional food sometimes, enriched with plant sterol or stanol esters that can lower blood cholesterol levels
Margarine vs vegetable oil spread
If the product contains less than 80 percent oil, then it must be labeled as a "vegetable oil spread". Fat content of margarines vary widely
What are the animal Shortenings?
Lard, Tallow and Butter
Whipped margarines
Light blends of margarine and butter, about 60% fat Whipped in air
Spray/pump products
Liquid -> spray Advertised as zero everything but each spray averages just under a calorie and 15 mg sodium for each 5 sprays (not truly a zero kcal product) Best for topping and sauteing
Cocoa Butter
Melting point is just below body temperature and is therefore perfect for "melt in your mouth" chocolates and candies
European Style/"Cultured Butter"
More fat and less moisture than regular butter Used in production of flaky pastries like croissants Made from fermented cream that gives it a tangy flavor
Unsalted butter
Most used in cooking and baking (most versatile)
Regular tub margarines/spread
Mostly vegetable oil and are now labeled as trans fat-free although some still have it Some have added calcium Best for spreading, melting or sauteing Not good for baking, reduces volume of baked product
Salted butter
Not as good for cooking/recipes as unsalted
Types of hydrogenated oils
Partially (high in TFA, ~ SFA) and fully hydrogenated (no TFA, high in SFA)
What milks can be used in butter?
Primarily cow milk but sometimes sheep, goat, yak or buffalo
Lard
Processed from hog fat, one of the best known and used to fry chicken, make mexican tamales, a flaky pie crust and southern lard biscuit
Plant stanol and sterol ester spreads
Proven to lower blood cholesterol if used daily Good for spreading (NOT BAKING)
Light, low-fat and fat-free spreads
Range from 0 to 40 percent vegetable oil Most healthy choice Diet/reduced kcal margarine tends to have a higher water content and stabilizers Best used for spreading
What color is butter?
Ranges from white to deep yellow
Whipped butter
best for spreading on toast or finishing dishes, less kcal than normal butter, fluffier and lighter texture
How many cups of milk does it take to make a stick of butter?
10 cups of milk per 1 stick of butter
Pasteurization of butter
All butter is pasteurized in the USA Raw milk/butter is prohibited in the USA
Fortification in Margarines
All margarines are fortified with vitamins A and D, some with E and B vitamins and some even have calcium Omega-3s and other oils, but may not be in sufficient amounts for a health benefit May also have sterols or stanols
Why shouldn't I use light/low-fat or fat-free spreads in baking?
Causes poor quality products like cookies to become bar cookies, cakes are dense and compressed crumb etc Don't melt and often burn Can't replace butter in some recipes
Composition of Margarine
Cultured Skim Milk Emulsifiers like lecithin, mono and diglycerides, soy lecithin Preservatives like sodium benzoate, potassium sorbate (to preserve freshness), EDTA, isopropyl citrate and citric acid Vitamins A and D flavorings like diacetyl Food colorings like annatto and beta-carotene
Butter
Dairy product from churning milk or cream (churning separates the butter fat from the milk / solids from liquids)
What is the biggest factor in butter?
Fat content
Spreadable butter
Generally lower in fat, STA and kcal than normal butter/margarine Combination of butter and vegetable oils and is best for spreading, not cooking/baking
Traditional stick margarine
Highest in trans fats = least healthy type of margarine Can be used as butter in cooking but has different, aroma, mouthfeel and taste More solid = more trans fats Good for spreading, melting baking and sauteing
Fake/butter-like spread
Soft texture and little to no butter Fewer calories and low cholesterol due to veggie oils
Inter-esterified Fats (IF)
The fatty acids are unchanged but shifted around to become more shelf stable
Hydrogenation
The process of heating the oil up, putting it under pressure and adding Hydrogen. Needs a catalyst like nickel or platinum to do.
