Moisture Content in Food Analysis

What does moisture content refer to in food analysis?

• The amount of water in the food sample

• The amount of fat in the food sample

• The dry matter in the food sample

• The protein content in the food sample

Total solids represent:

• The water content remaining in the sample

• The total carbohydrate content of the food

• The dry matter after moisture is removed

• The fat content of the food

What is the typical moisture content range for most food products for optimal storage?

• 10-14%

• 20-25%

• 90-92%

• 50-60%

Which method is most commonly used to measure moisture content in heat-sensitive foods?

• Oven drying

• Vacuum oven drying

• Karl Fischer titration

• Distillation

What is the principle behind Karl Fischer titration for moisture analysis?

• Evaporation of water through heat

• The reaction between water and a reagent

• The change in mass after drying

• Water removal through distillation

What does the Oven Drying method directly measure?

• The total carbohydrate content

• The weight loss due to water evaporation

• The fat content in the sample

• The protein content in the sample

Which water type is most easily evaporated and influences microbial activity in food?

• Free water

• Bound water

• Structural water

• Saltwater

The moisture content of a food sample is typically measured at what temperature range in oven drying methods?

• 90–95°C

• 100–105°C

• 200–210°C

• 70–80°C

What does the "wet basis" moisture content refer to?

• Moisture as a percentage of the total weight

• Moisture as a percentage of dry solids weight

• Total water content

• Water lost through distillation

Which of the following methods is used for high-fat or high-sugar food products to measure moisture content?

• Oven drying

• Vacuum oven drying

• Distillation methods

• Karl Fischer titration
