Published on the Food Directorate’s (Health Canada's) website at http://www.hc-sc.gc.ca/food-aliment.,Government of Canada Gouvernement du Canada,Laboratory Procedure ExFLP-15,September 1996,HEALTH PRODUCTS AND FOOD BRANCH,OTTAWA,DETERMINATION OF EXTRANEOUS MATERIAL IN DRIED, FROZEN AND,CANNED PEAS, BEANS AND LENTILS,Research Division, Bureau of Microbial Hazards,Food Directorate, Postal Locator: 2204A2,Health Canada, Ottawa, Ontario, K1A 0L2,1. APPLICATION,This method is applicable to the sampling and examination of dried, frozen and canned peas, beans and lentils,for insect infestation, mould, hairs, fibres, sand, soil and other extraneous material to determine compliance with,Sections 4, 5 and 7 of the Food and Drugs Act. This method replaces ExFLP-15 dated February 1988. The types,of peas, beans and lentils (Family Leguminosae) covered by this method include but are not limited to:,(a) Beans of the genus Phaseolus, such as French, string, snap or kidney beans (Phaseolus vulgaris L.), the,scarlet runner bean (P. coccineus L.) and the lima or butter bean (P. lunatus L.). White seeded types of,P. lunatus are usually grown because often coloured seeds have a relatively high cyanogenic glycoside,level which can be dangerous.,(b) Beans of the genus Vigna such as mung beans (Vigna radiata (L.) Wilszek), the species from which bean,sprouts are produced; the adzuki bean (Vigna angularis (Willd.) Ohwi and Ohashi), also called the aduki,or azuki bean, similar but with larger seeds than the mung bean, and which is red, cream, lilac, or mottled,in color; and the large podded faba or broad bean (Vigna faba L.) also called the lupini bean.,(c) Soybeans and soya seeds (Glycine max (L.) Merr.),(d) The true pea (Pisum sativum L.),(e) Cowpeas, black-eyed peas, crowder peas, field peas, and southern peas (Vigna unguiculata (L.) Walp.,subsp. unguiculata).,(f) Yard-long beans (Vigna unguiculata subsp. sesquipedalis (L.) Verdc.).,(g) Pigeon peas (Cajanus cajan (L.) Millsp.).,(h) Chick peas, garbanzos or bengal grams (Cicer arietinum L.), which are rounded seeds with a characteristic,beak resembling the head of baby chicken.,(i) Lentils (Lens culinaris Medik.).,ExFLP-15,- 2 - September 1996,2. DEFINITION OF TERMS,A lot is defined as that amount (volume, weight, etc.) of the food which is produced, stored and/or shipped under,conditions as nearly uniform as possible, preferably designated by a common container code or marking, and, in,any event, consisting of not more than one variety, grade or type of product from a single identifiable source.,3. COLLECTION OF SAMPLES,3.1 Scrutinize the entire lot for live infestation. If live infestation is found, do not sample until after fumigation,or other effective treatment.,3.2 (a) For canned products obtain three sample units selected at random from the lot. Each sample unit,should consist of whole cans to a minimum weight of 500 g. Three sample units constitute a,sample.,(b) For frozen products obtain three sample units selected at random from the lot of at least 500 g,each, using appropriate sampling equipment and containers. Three sample units constitute a,sample.,(c) For dried products obtain eight sample units selected at random from the lot of at least 50 g each,using appropriate sampling equipment and containers. Eight sample units constitute a sample.,3.3 Each sample unit must be kept separate and labelled 1, 2,3 etc. Complete information respecting the lot,size, weight of individual containers, country of origin, exporter, importer or domestic manufacturer and,product and lot identification should be recorded and should accompany the sample.,4. MATERIALS AND SPECIAL EQUIPMENT,1) Light colored tray,2) Magnifying lens (3-5x),3) Steroscopic microscope (10-30x),4) Alcohol (70%), either ethanol or isopropanol,5) Absorbent paper,6) Scalpel,7) Forceps (No. 5 or No. 7 jeweller's forceps or equivalent),8) Isopropanol (100%),9) Spot plate,10) Magnifying lens (3-5x),11) Glycerol - alcohol mixture (1:1),12) Compound microscope (100x),13) U.S. standard sieves No. 8 and No. 40,14) Shallow pan > 20 cm in diameter,15) 2 L beaker,ExFLP-15,- 3 - September 1996,14) Meat or food chopper,15) Trap flask or heavy walled side arm flask (2 L),16) Ruled filter paper. Paper should be larger than funnel,17) Suction filtration apparatus with Hirsch funnel,18) Petri dishes suitably sized to fit ruled filter paper,19) Heptane,20) Glycerol-alcohol mixture (1:1),5. PROCEDURE - MACROSCOPIC EXAMINATION OF DRIED PEAS, BEANS AND LENTILS FOR INSECT,DAMAGED DEFECTIVES.,The examination shall be carried out in accordance with the following instructions.,5.1 Preparation of Analytical ……
