Peanut Inspector Certification Practice Exam

Which sampling method requires a cut to be made in sacks for obtaining samples?

1. Pneumatic Sampling

2. Horn Sampling

3. Spout Sampling

4. Farmers' Stock Sample Division

The correct answer is: Horn Sampling

Horn sampling is a method utilized in the context of obtaining samples from multiple sacks of a product, particularly peanuts. This technique involves the actual cutting and opening of the sacks to collect samples adequately. Horn sampling is especially beneficial for ensuring that samples represent the overall quality and integrity of the entire batch being inspected. It allows inspectors to draw a sample from the heart of the sack, which can help in identifying any issues related to contamination or spoilage that might not be detectable in samples taken from the exterior. This approach contrasts sharply with other sampling methods like pneumatic or spout sampling, where no physical cuts are made to the sacks. Such methods typically involve the use of devices that automatically extract samples without opening the container, maintaining the overall condition of the product. Farmers' Stock Sample Division is another sampling method that focuses on distinct divisions of the bulk product rather than direct cuts into the sacks. By employing horn sampling, inspectors can ensure that the samples obtained are representative and dependable for making quality assessments.
