To Estimate The Caloric Value Of Food Taken

Example : An infant takes 6 feedings of 210 c.c each of Formula 25, the caloric value of which is 720. The caloric value of the food ingested is, then, 210 X 6/ 1000 x 720 = 906.2 calories.

To Estimate Weight Development Of An Infant

To estimate the weight development of any infant, calculate as follows: -

Weight index =Weight of an infant / Weight of average infant of same age Example: An infant of 18 weeks weighs 12 lbs.

Its weight index =12/14 =.85. Its weight development = .85X100 = 85 per cent.

Table V. Methods Of Calculating Approximately The Percentage Composition Of A Food From Known Amounts Of Ingredients Used

Let C=number of ounces of cream used. " M=number of ounces of fat-free milk used. " L=number of measures of milk sugar (or level tablespoonfuls). " Q = total quantity of mixture in ounces.

Then (1) Fat percentage = CX fat percentage of cream / Q.

(2) Proteid percentage=3.50 (C+M)./ Q.

(3) Sugar percentage =4.75 (C+M)+40 L. / Q.

If whole milk is used in place of fat-free milk, add to the quotient in (1) the amount of fat contributed by the whole milk, M1 standing for number of ounces used; i. e.,

(4) Fat percentage in milk = M1X4 / Q.

Example: A 20-ounce mixture consists of 7 ounces of 10 per cent, cream, 2 ounces of fat-free milk, 1 ounce of lime-water, 10 ounces of boiled water, 2¼ measures of sugar.

Solution: Fat percentage = 7 X 10 / 20 = 3.50%.

Proteid " = 3.50 (7+2) / 20 = 1.57%.

Sugar " = 4.75 (7+2) + 40 X 2¼ / 20 = 6.63%.

The fat percentage of cream must be calculated by reference to the cream table, page 426.

Infant Food - Modified Milk Formula

6 ounces cream.

7 teaspoons sugar of milk.

1½ teaspoons Gum Gluten Flour.

4 ounces lime water. 18 ounces filtered or boiled water.

Thin gluten with a little cold water then add to the boiled water and let boil 15 minutes. When cool add to the other ingredients. This formula is for 4 full sized bottles or enough for ten feedings, infant being fed every two hours through the 24. As child grows older, reduce the amount of cream replacing the same with milk.

Formulae For Preparing Infant Food From Pure Sterilized Sugar Of Milk

Fresh, Pure Milk, 1 ounce.

(about 2 tablespoonfuls) Fresh Cream, 1½ ounces.

(about 3 tablespoonfuls) Sugar of Milk, 3½ drachms.

(4 even teaspoonfuls) Bicarbonate of Sodium, 1 grain.

(or use fresh limewater, 2 teaspoonfuls) Water, 5 ounces.

(1¼ gills)

Mix enough for one day's use, and sterilize. Be sure feeding bottles, nipples, etc., are kept perfectly clean.
