Foreign Materials in Food Products
Abstract
This practical was carried out to learn the uniform evaluation of foreign materials in processed fruit and vegetable commodities. The main focus is on light filth analysis and the method used is Wildman method. It is also called Light filth flotation method since the food will remain in the aqueous layer and settle at the bottom while light filths are collected in the oil layer at the top. So after separation light filths are collected on filter paper and observed under microscope. Rodent hairs and insects legs were found indicating the presence of light filths.
Introduction
Analysis for extraneous matter is an important element both in the selection of raw materials for food manufacturing and for monitoring the quality of processed foods. The presence of extraneous material in a food product is unappealing and can pose a serious health hazard to the consumer. It also represents lack of good manufacturing practices and sanitary conditions in production, storage, or distribution. The presence of extraneous materials in the product ingredients may render the final product adulterated and not suitable for human food. Extraneous material guidelines includes foreign matter associated with objectionable conditions or practices in manufacturing, processing, storing, transporting and handling of food. Since fresh as well as processed broccoli is consumed widely in Canada, processes should be carried out to confirm that field insect fragments and unidentified field insect fragments is not more than particular limit. So the main objective of the practical is to examine the light filth analysis of frozen broccoli using Wildman method for aphids and thrips.

50 and 100 ml. graduated cylinders
Buchner funnel and screen
Filtering flask, heavy walled
Filter pump
Ruled filter paper, 9cm diameter
Stirring rods
Wash bottles
Sharp probe
250 and 400 ml
