Blanching is an important preUminar>' step in the cold-paek
tnethcMl of canning. It is used for s<jme fruits and may bi! uaed
for all vegetables. Blanching may be done with either boiliag
water or steam.
When boiling water is used, the fruit or the vegdelable tt
placed in a piece of cheeseK'loth or a crate, lowered eotindy
under the water, and heated for the required numlx*r of miuutis
(pages GI2 to 614). Only a small quantity of the produel

should bo blanched at a time in order that the water may be

Delicately fiavorwi greens are generally blanched by steam
in order to avoid the loss of iron and other nutrients that oc-
curs when they are inimemed in boiling water. For hlancliing
in steam, the food is placed in some perforateil utensil or a
piece of cheese-eloth and suspended in a tightly closed steamer.
The food should be lilanched until no further shrinkage will
occur; Blanching in steam generally requir-es n longer time
than blanching in boiling water. The Hteani nmsfr penetrate
to all parts of the mass, and for this reason the fruits or vege-
tables should not be crowded together. Blanching in steam
is not recommend tH I for strong-flavorefl greens.
Blanching may accomplish one or more rc^sults: (1) it helps
to insure a ck>se pack either by contracting the tissue and
making the product flexible, as in the case of string beans
and asparagus, or by causing a decided shrinkage, rui with
greens; (2) it may partly eliminate strong acids or i utter flavors;
(3) it may set the color; (4) it ]>egins the sterilization of the food ;
(5) it loosens the skins of ceriain fruits and vegetables from
the pulp so that they may lie slitiped or scrapetl off easily, as
in the case of peaches, tomatocvs, or carrots. When blanching
serv^es this last purpose, it is frequently calletl scalding. Blanch-
ing may not be necessary but it is believed to give a superior
product in many cases.
The cold tlip is the rapid chilling of the outside of the blanched
fruit or vegetable by plunging it into cold wiiter. While the
food may neeil to be cold dipped in order to be c€H:>led sufBciently
to make it easily handled and to insure the cooling of the center
of the mass, it should not he allow^ed to remain long in the
cold water.
