Chapter 1: Basic Foods (6) Flashcards
end point of baking
when a dent, when touched, springs back
toothpick inserted comes out clean
stiff dough made with flour, shortening, and water that has very low moisture, and high fat
should be flaky but crisp and tender, not doughy
pastries
pastry ingredients
flour used for a more cohesive dough
ap flour
pastry ingredients
flour used for a more tender, crumbly pastry, may be substituted with 60% soft flour and 40% hard flour
gluten is not needed
pastry flour
pastry ingredients
shortening used
plastic fats
pastry ingredients
shortening that is better than lard for sweet pastries
vegetable fats
pastry ingredients
shortening that is better for empanadas
lard
pastry ingredients
liquid temp to keep fat particles in firm state
cold or iced state
too much liquid in pastries produces
too much gluten; pasty product
too little liquid in pastries results to
crumbly and browns easily
pastry ingredients
salt used for flavor, omitted if salted fat is used
fine salt
pastry ingredients
is used for sweet pies only, for flavor, and for brown crust
sugar
pastry ingredients
leavening agent
steam from the liquids
rolling out and shaping dough
dough is rolled out between pieces of _____, removed, and placed in an ungreased pan
waxed paper
rolling out and shaping dough
bottom crust is pricked with _____, and top crust is cut (_____) to provide a vent for steam to escape
fork
slit
baking temp of pastries
425-445F
batters are similar to most cake batters except that less liquid is used and proportionately more fat and eggs are added, producing dry, crisp products
cookies
mixing methods for cookies
creaming, one-stage, sponge
storing for crisp cookies
loosely
storing for soft cookies
tightly
pie crust ingredients
flour, fat, liquid, salt
molded desserts
a by-product of the meat industry
obtained by hydrolyzing collagen
made up of high proportion of proline and hydroxyproline
has increased affinity to water, thus used in gel formation
gelatin
types of gelatin available
have no flavor and color
ex: knox
plain type
types of gelatin
artificially flavored and colored
sweetened types
factors affecting gel formation
lower the temp at which the gel will form = longer time to gel
responsible for soft tender gel, clearer gel, more stable gel
acids
factors affecting gel formation
prevents gel formation because bromelin (enzyme), hydrolyzes gelatin molecules
raw pineapple
factors affecting gel formation
increases gel strength due to salts content = hard water producers firmer gel
milk
factors affecting gel formation
retards setting, resulting in weaker gel
sugar
a gel-forming extractive from algae or seaweeds obtained by a series of extraction with water and sulfuric acid
agar-agar (gulaman)
gulaman vs gelatin
_____ non-digestible cho
agar-agar
gulaman vs gelatin
_____ is a protein
gelatin
gulaman vs gelatin
gels at room temp
gulaman
gulaman vs gelatin
requires low temp
gelatin
gulaman vs gelatin
firm and brittle
breaks with sharp edges, is not clear
gulaman
gulaman vs gelatin
soluble in boiling water
gulaman
gulaman vs gelatin
dissolves in hot water
gelatin
gulaman vs gelatin
not affected by raw pineapple
gulaman
gulaman vs gelatin
gel may be reversible
gulaman
frozen desserts
10% butter fat, 20% milk solids, sugar, flavoring, and egg or gelatin as stabilizer
ice cream
frozen desserts
imitation ice cream using vegetable fat instead of butter fat
mellorine
frozen desserts
2% butter fat, milk, sugar, fruit
sherbet
frozen desserts
no fat, flavoring, water, sugar
ices
frozen desserts
mixture of liquid flavorings and water
can contain milk
popsicle
frozen desserts
sweetened whipped cream and gelatin
mousse
mixtures of ice crystals floating or suspended in syrup in which air bubbles had been incorporated
frozen desserts
main ingredient of frozen desserts
water in the form of free water in milk or fruit juice
ice crystals
type of suspension or emulsion, a solution or a foam
frozen desserts
added sugar makes the mixture like a
syrup
air incorporated makes the mixture like a
foam
characteristics of frozen desserts
refers to firmness or resistance to rapid melting
body
characteristics of frozen desserts
related to size of crystals and distribution of ice crystals
texture
characteristics of frozen desserts
air incorporated during the preparation
30-40% or 80-100% for commercial ice cream
overrrun or swell
factors influencing the characteristics of frozen desserts
influences texture and flavor
lowers freezing point of water, slowing down crystallization
sugar
too much fat in ice cream result to
sticky, heavy ice cream
ice cream made with _____% milk fat have finer texture than made with whole milk and lower fat content
18%
type of milk more effective in producing finer texture than unhomogenized milk
homogenized milk
ice creams made with _____ are finer than those with whole milk
evaporated milk
limit the size of crystals more effectively than fat, results in finer texture
milk solids
it favors development of small crystals when the mixture begins to freeze
agitation
favors incorporation of varying amounts of air, resulting in an increased volume of the frozen product
agitation
freezing the product
when pure water is cooled for _____C, heat is removed
expansion of water molecule occurs, resulting in an increase in volume
at _____ crystallization of water occurs
4C; 0Z
in an ice cream mixture, as the ice crystals begin to form at _____C, water is removed from the syrup
concentration of sugar in the syrup increases, and the temp at which the remaining water crystallizes becomes progressively lower, explaining why ice cream does not freeze solid hard but mixture becomes only thick and stiffer
-2 to 5C
freezing the mixture
brine
function of salt and ice
freezing the mixture
ionizes and lowers freezing point of ice
salt
freezing the mixture
salt used for brine
coarse salt
freezing the mixture
ratio of salt to ice for slow freezing and fast freezing or ripening
1:8; 1;4
freezing process
_____ with rapid agitation as crystallisation starts to develop at 140 rpm
freezing end point is when it is difficult to turn the crank
mixture is partially frozen at 30%
may result in the formation of big crystal’s
