CAN ALL FOOD THAT CAN BE CANNED 



5. Vacuum Seal Method: Vegetables are 

 washed, blanched, cold-dipped and cooked 

 asfortable use; packed and sealed in especially 

 made vacuum seal jars. The jars must be 

 well made and the work properly done to 

 bring about satisfactory results. 



ADVANTAGES OF THE COLD-PACK 



The Single Period Cold-pack method is 

 a simple and sure way of canning. It in- 

 sures a good color, texture and flavor to the 

 vegetable or fruit canned. In using this 

 method sterilization is completed in a single 



f _ — ^ period, saving 



time, fuel and 

 labor. The sim- 

 plicity of the 

 method c o m - 

 mends it. Fruits 

 are put up in 

 syrups. Vege- 

 tables require 

 only salt for 

 flavoring and 

 water to fill the 

 container. 



Another ad- 

 vantage is that 

 it is practicable 

 to put up food 

 in small as well 

 as large quanti- 

 ties. The house- 

 wife who un- 

 derstands the 

 process will find 

 that it pays to put up even a single con- 

 tainer. Thus, when she has a small surplus 

 of some garden crop she should take the 

 time necessary to place this food in a con- 

 tainer and store it for future use. This is 

 true household efficiency. 



COLD-PACK EQUIPMENT 



1. The Homemade Hot-water Bath Outfit. — 

 A serviceable Single Period Cold-pack can- 

 ning outfit may be made of equipment found 

 in almost any household. Any utensil large 

 and deep enough to allow an inch of water 

 above jars, and a false bottom beneath them, 

 and having a closely fitting cover, may be 

 used for sterilizing. A wash-boiler, large lard 

 can or new garbage pail serves the purpose 

 when canning is to be done in large quantities. 

 Into this utensil should be placed a wire or 

 wooden rack to hold the jars off the bottoin 

 and so constructed as to permit circulation of 

 water underneath the jars. 



For lifting glass-top jars use two button- 

 hooks or similar device. For lifting screw- 

 top jars, suitable lifters may be bought for a 

 small sum. A milk carrier makes a good 

 false bottoin, and if this is used the jars 

 may be easily lifted out at the end of the 

 sterilization period.

2 . Commercial Hot - water Bath Outfits. — 

 There are upon the market outfits on the order 

 of the wash-boiler or pail type of homemade 

 canner. These are excellent and are es- 

 pecially desirable if one has considerable 

 quantities of vegetables or fruits to put up. 

 There are also commercial canners conve-

nient for out-door work, having fire-box and 

 smoke-pipe all in one piece with the sterilizing 

 vat. As with the homemade outfit, contain- 

 ers are immersed in boiling water. 



3. Water Seal Outfits. — These are desirable, 

 as the period of sterilization is shorter than in 

 the homemade outfit and less fuel is therefore 

 required. The outfit consists of two con- 

 tainers, one fitting within the other, and a 

 cover which extends into the space between 

 the outer and the inner container. The 

 waterjacket makes it possible for the tem- 

 perature in the 



mner contamer 

 to be raised 

 several degrees 

 above 212° F. 



4. Steam Pres- 

 sure Outfits. — 

 Canning is very 

 rapid wlien ster- 

 ilization is done 

 in steam main- 

 tained at a pres- 

 sure. There are 

 several canners 

 of this type. 

 Each is pro- 

 vided with pres- 

 sure gauge and 

 safety valve and 

 they carry from 

 5 to 30 pounds of steam pressure. This type 

 is suitable for home or community canning. 



5. Aluminum Pressure Outfits. — These cook- 

 ers are satisfactory for canning and for general 

 cooking. The)' carry from 5 to 30 pounds of 

 steam pressure. Each outfit is provided with 

 a steam pressure gauge and safety valve. 



HIGH ALTITUDES 



At high altitudes the boiling point of 

 water is below 212° F. At moderate eleva- 

 tions satisfactory results may be obtained 

 in the use of the hot-water bath by increasing 

 the time of sterilization 10 per cent for every
