JELLY

prepared by boiling fruit juice extract with or without water, sugar, and concentrating to a point where gelatinization takes place upon cooling

MARMALADE

a clear jelly in which are suspended slices of fruit or peel

JAM

prepared by boiling whole fruit pulp with sugar to a moderately thick consistency

FRUIT PRESERVE

fruits or combination of fruits cooked in syrup but retaining the shape or shapes of the fruits

PASTE CANDIES

prepared by boiling mashed fruit pulp with sugar to a homogenous semi-solid mass

CANDIED FRUITS

prepared by gradually concentrating fruits in syrup by repeated boiling until the fruit is heavily saturated with sugar, then, dried

ACID

inversely proportional to pectin content

SYNERESIS / WEEPING

if acid is above 3.5 (too much) because of dehydrating effect of pectin on acid, causing it to pick up some liquid or syrup (pectin hydrolysis)

INVERT SUGAR

During the process of boiling sucrose solutions in the presence of acid, hydrolysis occurs in which sugar is formed. Sucrose is converted to reducing sugars called "____".

TEMPERATURE


TIME OF HEATING


PH VALUE

The rate of inversion is influenced by ___,___,___

PLUMPING

soaking fruits at progressively increasing sugar concentration

SLACK JAM

Failure in jam and marmalade making due to overripe fruits, overcooking, insufficient acid, and too much stirring

EXTRACT PECTIN


EXTRACT FLAVOR


OBTAIN MAXIMUM YIELD OF JUICE

Reasons for boiling fruit (3)

PECTIN HYDROLYSIS


ACID VOLATILIZATION


LESS FLAVOR AND COLOR

Prolonged boiling can cause ___, ___, ___

SYRUP PACK

Type of packed fruit for freezing generally best for uncooked dessert use

40%

recommended syrup percentage for most fruits in syrup packs

LIGHT SYRUP

Syrup pack desirable for mild flavored fruits to prevent masking of flavors

SWEETNESS OF FRUIT TO BE FROZEN

proportion of sugar to water in a syrup pack depends on this

HEAVY SYRUP

syrup pack needed for very sour fruits

1/2 to 2/3 cups

# cups of syrup for each pint of packed fruitd

SUGAR PACK

Type of fruit pack for freezing; sprinkle sugar over fruit and mix gently until juice is drawn out and sugar is dissolved or layer and allow to stand for 15 mins

SUGAR PACK

Type of fruit pack for freezing best for fruits used for cooking purposes because of less liquid in product

INVERT / REDUCE SUGARS

type of sugars formed to prevent crystallization

WATER ACTIVITY

Inversely proportional with osmotic pressure

GREATER

_____ sugar concentration = greater osmotic pressure

SUGAR

The more pectin, the more ____ is needed for pectin precipitation and branching.

LESS

The greater the acidity of the fruit, the ___ sugar should be added so the mixture won't be a hard / tough candy.

SUCROSE + ACID + HEAT

3 components of sugar concentrates which prevent crystallization

OSMOTIC DEHYDRATION

Principle of food preservation with sugar

OSMOSIS

Movement of water from low to high concentration gradient

PLASMOLYSIS

Movement of water out of the cell which causes shrinkage

DESSICATION

Dryness of the cell

SUGAR CONCENTRATES

products from fruits and other parts of plants with added sugar after concentration by evaporation to a point where microbial spoilage cannot occur

60-65 %

percentage range of concentration of sugar concentrates

PECTIN

provides structure of jelly; found in fruits

PROTOPECTIN

ripe : pectin ; unripe : ______

ACID

provides rigidity of structure

SUGAR

controls the strength or rigidity of the jelly

3.4 - 3.2

optimum pH of a good jelly

VISCOSITY TEST

pectin content test; state of being thick, sticky, and semi-fluid in consistency

GREATER

The greater the amount of pectin, the ___ the viscosity

JELMETER

device used to test amount of pectin; high pectin if juice runs down slowly

1 Tbsp fruit juice to 2 Tbsp denatured alcohol

In alcohol test, mix __Tbsp of fruit juice to __Tbsp denatured alcohol

BIG LUMP OF JELLY

In alcohol test, if ____________ is formed upon addition of denatured alcohol, the mixture is high in pectin.

TEMPERATURE TEST

pectin content test; setting at 8.5-10.5°F above 212°F (220-225.5°F)

COLD WATER TEST

pectin content test; placing a small amount of jelly in cold water (it should set immediately)

1tsp lemon/calamansi juice
1 T water
1/2 tsp sugar

PH TEST STANDARD:
__ tsp lemon/calamansi juice
__ T water
__ tsp sugar

REFRACTOMETER TEST

End point determination test; cool jelly at 60°F, and test °Brix

67.5%

Total °Brix or soluble solids for end-point determination through refractometer test

SHEETING OR FLAKE TEST

End point determination test; mixture drops together forming sheets or flakes which break off in a clean, sharp manner

COLD PLATE TEST

End point determination test; surface sets or crinkles when pushed with finger

TOO MUCH SUGAR


PROLONGED BOILING


CRYSTALLIZATION

CRYSTALLIZATION

failure in jam & marmalade making; caused by too much sugar, too long/slow cooking, or undissolved sugar on the side of the pot
