Syrups Flashcards
Are concentrated solutions of sugar in water
syrups
types of syrups
medicated syrups
flavored syrups
provide an excellent nutrient for molds, yeasts, and other microorganisms
dilute solutions of sucrose
will retard the growth of microorganisms
concentrations of 65% by weight or more
(method of preparation) Employed when the valuable constituent is neither volatile nor injured by heat and when syrups are prepared rapidly
solution by heat
heat should be regulated because…
it will lead to caramelization or the formation of invert sugar
(method of preparation) Used in cases where heat would cause the loss of valuable volatile constituents
agitation without heat
(method of preparation) Employed in cases where fluidextracts, tinctures or other liquids are added to syrup to medicate it
addition of medicating liquids to syrups
(method of preparation) It permits purified water or aqueous solution to pass slowly through a bed of crystalline sucrose to dissolve it
percolation
preservation and storage of syrups
Syrups should be prepared in small quantities that can be used within a few months
ways of preserving syrups
o Preparation and storage at low temperatures not above 25C
o Concentration without supersaturation
o Addition of preservatives
sucrose ; solution in simple syrup
85 g sucrose per 100 mL of solution
syrup has a specific gravity of about…
1.313
each 100 mL of syrup weighs
131.3 g
it takes _____ of water to prepare the solution
46.3 mL of water
(131.3 - 85 = 46.3)
