Estimating moisture content for beans with no conversion tables

Dutch brown beans

1. Determine sample size and moisture content from pea bean conversion table No. 2.
2. Subtract 1.1 from the table result.

Great northern white beans

1. Determine sample size and moisture content from pea bean conversion table No. 2.
2. Subtract 1.4 from the table result.

Kintoki beans

Use dark red kidney bean conversion table No. 2 to determine the size of the representative portion and the moisture content.

Otebo beans

1. Determine sample size and moisture content from pea bean conversion table No. 2.
2. Subtract 0.3 from the table result.

Pink beans

1. Determine sample size and moisture content from pea bean conversion table No. 2.
2. Subtract 1.1 from the table result.

Small red beans

1. Divide a sample of 250 g.
2. Use the following regression formula, where
3. T = sample temperature (°C):
4. % moisture = 0.155 x meter reading + 8.03 + {0.l x (22 - T)}

Example

The pea bean conversion table No. 2 shows a sample of 250 g is required.

A sample of great northern white beans shows a meter reading of 25 at 18°C. According to the table, the moisture content for pea beans at this reading is 13.6%.

To adjust this moisture content for great northern white beans, subtract 1.4.

The moisture content of the great northern white beans is 13.6-1.4, or 12.2.
