2
Introduction

• You know from experience that when a recipe calls
  for a certain amount of meat, vegetables or
  fruit, that you will need to buy more than what
  is required.

3
Introduction

• This is necessary because

4
Introduction

• Because of the trimming and cutting, you will
  always end up with less product than when you
  started.

5
Introduction

• The amount of a food product that comes from a
  store or supplier is called the AP Weight.
• AP is an abbreviation for As Purchased.
• The AP Weight describes the amount of a food in
  unprepared form.

6
Introduction

• The amount of a food product required by a recipe
  is called the EP Weight.
• EP is an abbreviation for Edible Portion.
• EP Weight describes the amount of food in
  prepared (ready to eat) form.

7
Introduction

• For a given product there is usually a
  predictable amount that will be trimmed away.
• For example, with carrots, usually 75 by weight
  remains after trimming.
• The 75 figure is called a Percentage Yield.

8
Introduction

• Percentage yields can help you with purchasing
  decisions.
• By having a recipe with the required EP Weight,
  you can use the percentage yield to compute the
  AP Weight.

9
Introduction

• You can also use percentage yields to determine
  if the amount of a given product that you have
  on-hand will be enough to make a given recipe.

10

• In this lesson you will learn how to

Percentage Yield

• Lets take a moment to learn how to compute the
  percentage yield for a given product.

12
Percentage Yield

• To compute percentage yield
• Weigh the product as purchased to determine AP
  Weight. This is done before any trimming or
  peeling.

AP weight 14 oz
13
Percentage Yield

• To compute percentage yield
• Then weigh the product after trimming. The
  amount remaining is the EP (Edible Portion).

EP weight 11 oz

• To finish, compute the percentage yield
  (sometimes called the EP ) using the standard
  percent formula.

• Use cross-multiplication to solve for R.

Step 1) Multiply on the diagonal.

17
Percentage Yield

• Use cross-multiplication to solve for R.

Step 1) Multiply on the diagonal.
11 x 100 1100
Step 2) Divide this result by the number that is
on the diagonal with the unknown.
1100 14 79

Percentage Yield

• Based upon this kitchen experiment, it appears
  that the percentage yield for these carrots is
  79.

19
Percentage Yield REVIEW

• To compute Percentage Yield

1.) Weigh the food item as-purchased (AP weight)
2.) Trim the food as necessary, then weigh it
again (EP weight)
3.) Put the EP weight and AP weight results into
the percent-solving formula

Percentage Yields

• It is not necessary to conduct a kitchen
  experiment every time you want to know a
  percentage yield.
• Textbooks and other sources often have several
  pages of percentage yields.

Compute AP Weight
Introduction
34
Calculate AP Weight

• Of what use are percent yield numbers?

Percent yield predicts the amount of trimming
loss to expect for a given food item.
Because of this, you can make informed decisions
about how much of a given product to purchase (or
gather from a storage area) in order to have
enough for a recipe.

Calculate EP Weight

• You have just learned how to use percent yield
  numbers to compute AP Weight when a recipe weight
  (EP Weight) is given.
• Now lets learn how to compute EP Weight when you
  know the AP Weight and the percent yield.
