monosaccharides
hydrolyzed from maltose, lactose, or sucrose
present in animal tissues as blood glucose
glucose

also known as fruit sugar
does not crystallize readily
sweetest among all sugars
fructose
fructose is aka
levulose or fruit sugar
not naturally found in food except as a component of lactose or milk sugar
galactose
composed of 2 monosaccharides
disaccarides
on hydrolysis: yields 1 molecule of glucose and 1 molecule of fructose
sucrose
aka milk sugar
on hydrolysis: yield 1 molecule of glucose and 1 molecule galactose
lactose
aka malt sugar
derived from grains and starch
on hydrolysis: yields 2 glucose units
maltose
sweetest sugar; least sweet sugar
fructose; lactose
sugar solubility
sugar is _____ to crystallization; _____ related to hygroscopicity and intensity of sweetness
inversely; directly
sugar solubility from most to least soluble (F, S, G, M, L)
fructose
sucrose
glucose
maltose
lactose
formation of crystals from concentrated sugar solutions
important in candy making
inversely related to ease of solubility
crystallization
hardest to crystallize; easiest to crystallize
fructose; lactose
T/F acids retard/prevent crystallization
T
ability to absorb moisture from air; has a dehydrating effect on microorganisms that is used in food preservation
directly related to sweetness
hygroscopicity
produced when sugars are heated with a source of amino acids
protein + sugar
ex: milk, four, pastillas, etc.
maillard browning
_____ of sucrose in the presence of acid, enzymes, invertase, or alkalis gives equal amounts of glucose and fructose (invert sugar)
hastened by high temperatures
inversion or hydrolysis
gives sweetness to foods
reduce the tartness or acidity; tones down saltiness
sweetening agent
sugar as volume and structure improver
in jelly making, sugar acts as a _____ agent and facilitated precipitation of pectin to from the gel network
this effect is also responsible for the sugar’s ability to stabilize egg white foams
dehydrating agent
sugar as volume and structure improver
in baking, it serves as the substrate for _____ by yeast in producing co2 in yeast-leavened breads
fermentation
when beaten or mixed, has the ability to incorporate air as when creaming with fat
produces better volume
sugar as?
leavening agent
together with fat, prevents gluten particles from coalescing, producing tender, fine-grained, textured product
sugar as?
peptizing agent
means coming together or uniting into a single group or mass. It is often used to describe the merging or blending of elements, ideas, or physical entities
coalescing
undesirable effect of sugar
loss of crispness of cookies and meringues (ex. sans rival cake) on standing is due to
absorption of moisture from air
undesirable effect of sugar
melting of candies is due to
inversion of sugar
shrinkage, shriveling, and toughening of food cooked in sugar
ex: fruits and beans
is due to
dehydrating effect of sugar
chemical process where sucrose (table sugar), a disaccharide, is broken down into its component monosaccharides: glucose and fructose
process is called?
inversion of sugar; hydrolysis
hydrolysis often involves the use of acid (lemon juice) or the enzyme??`
invertase
sugar: market forms
derived from cane or beet
also called as refined sugar
fineness and whiteness depend on degree of refinement
ex: table sugar
crystalline or granulated
sugar: market forms
is slightly brown but not as “brown” as brown sugar
one step short of the complete refining process
washed sugar
sugar: market forms
made by pressing wet sugar crystals into a loaf and then cutting into cubes or tablets
lump sugar
sugar: market forms
partially purified
may range in color from light brown to very dark brown depending on degree of purification (the lighter the color, the more purified)
contains more moisture than refined sugar
coarse-to-fine
soft, refined sugar with a coating of molasses
brown sugar
sugar: market forms
dark, coarse, and sticky unrefined crystals that are separated from molasses
also called as muscovado or kinugay by the visayans
raw brown sugar
sugar: market forms
prepared by evaporating the sugar cane extract to a brown syrupy concentrate and pouring the resulting mixture into small halved coconut shells
the sugar that crystallizes out and dries up into a solid, brown concave mass is called sinakol or?
panutsa
sugar: market forms
specially screened, fine-grained sugar
known as caster sugar in britain
more fnely granulated sugar
perfect for making meringues and sweetening cold drinks since it dissolves almost instantly, thus better to use for creaming fat
superfine sugar
sugar: market forms
finest (“extra fine”), smoothest and whitish form of ground table sugar to which cornstarch has been added to avoid caking
used in frostings, candies, and dessert sauces
powdered or confectioner’s sugar
