8、part of a series on herbs and spices prepared for food use within the UK. For some years, BSI has published British Standards for herbs and spices in a variety of commercial forms. These British Standards were either identical with, or substantially related to, the corresponding international standa
9、rds published by the International Organization for Standardization (ISO). However, the Technical Committee decided that the requirements in the international standards did not correspond to the quality required by UK trade. The British Standards implementing those international standards are theref
10、ore being progressively withdrawn and replaced by Parts of BS 7087 for herbs and spices ready for food use. Attention is drawn to the requirements of the Food Safety Act 1990 1 relating to fitness, wholesomeness, nature, substance and quality with implications for the microbiological quality of drie
11、d herbs and spices, with particular references to contamination by pathogenic organisms of importance to human health. Attention is also drawn to the microbiological methods given in BS 5763. The dilutions of test samples of herbs and spices may need to be greater than the one in ten primary dilutio
12、n referred to in 3.1 of BS 5763 : Part 6 : 1983 because any natural antimicrobial compounds they might possess would inhibit the growth of micro-organisms until diluted out. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pages This document c

Sesame seed is sometimes supplied to the retail trade as multiple packs of retail units. 4 Sampling 4.1 General Laboratory samples shall be prepared in accordance with BS 4540 : Part 1, taking due account of the amou
20、nt required for each test. 4.2 Chemical tests Samples for chemical tests shall be prepared in accordance with annex B. 5 Physical properties 5.1 Flavour The sesame seed shall be free from mustiness, rancidity and other foreign odours and tastes when examined by sensory analysis. NOTE 1. Sesame seeds
21、 have a nut-like colour and an agreeable, nutty taste. NOTE 2. Methods of sensory analysis are described in BS 5929. 5.2 Freedom from contamination The sesame seed shall be free from living insects and mould growth when inspected visually. NOTE. It should be free in practical terms from dead insects
22、, insect fragments and rodent contamination visible to the naked eye (corrected if necessary for abnormal vision). 5.3 Extraneous and foreign matter The content of extraneous and foreign matter in sesame seeds shall not exceed 1 % (m/m) when determined in accordance with BS 4585 : Part 1 : 1983. 5.4

24、96 on or in relation to a product represents a manufacturers declaration of conformity, i.e. a claim by or on behalf of the manufacturer that the product meets the requirements of the standard. The accuracy of the claim is solely the claimants responsibility. Such a declaration is not to be confused
25、 with third party certification of conformity, which may also be desirable. 6 Chemical composition NOTE. For information on trace metal contents in these products see C.6. The chemical composition of whole sesame seeds shall conform to the relevant requirements specified in table 1. Table 1. Chemica

27、torage To avoid condensation, a container that is permeable to air shall be used for the packing and storing of bulk material. NOTE 1. Hessian, synthetic fibre or multi-ply paper sacks (sometimes plastics-lined) or plastics-lined cartons are most commonly used. NOTE 2. Bulk material should be stored
28、 in a clean, dry, ventilated room, free from infestation and not exposed to direct sunlight. NOTE 3. For those packs that do not exceed 1 kg in net mass, problems of condensation are unlikely to arise, therefore, normal types of food packaging may be used (e.g. tubes made from plastics, paper or boa
29、rd, glass jars, lever lid tins and polyethylene bags in boxes). 8 Marking The marking of herbs and spices is covered by the provisions of the current UK food labelling legislation. However, should the manufacturer wish to claim compliance with this Part of BS 7087 by marking packs of sesame seed, th
30、e following information shall be marked. NOTE 1. The same information may be incorporated in the suppliers contract documentation. a) For bulk material: 1) the name of the food, e.g. whole sesame seed; 2) country of origin of crop; 3) net mass (in g or kg); 4) a statement of any special treatment, e
31、.g. fumigation or irradiation; NOTE 2. Reference should be made to current UK food legislation to ensure that such treatment of food is permissible. 5) the date of packing and the lot number; 6) the number of this Part of this British Standard, i.e. BS 7087/27 or BS 7087 : Part 27 : 1996 1) . b) For
32、 retail material: 1) the name of the food, e.g. dried sesame seeds; 2) the number of this Part of this British Standard, i.e. BS 7087/27 or BS 7087 : Part 27 : 1996 1) . NOTE 3. Reference should be made to those instruments currently in force.BS 7087 : Part 27 : 1997 BSI 1997 3 Annexes Annex A (norm
33、ative) Description of dried, dehulled sesame seeds A.1 Dried, dehulled sesame seeds Sesame is the dried, dehulled and cleaned seed of the annual herbaceous plant, Sesamum indicum L. and its sub-species/varieties thereof. 70 to 100 seeds are contained in dehiscent seed pods, or capsules, which split
34、open at maturity. The colour of the unhulled seeds varies from yellowish-white to black through shades of grey and brown. Dehulling, or removal of the seed coat, reveals a slightly hard, flat, oval, smooth and shiny seed, creamy or pearly white in colour, 2.5 mm to 3.5 mm long, 1.5 mm to 2.0 mm wide
35、 and no more than 1 mm thick. A.2 Toasted sesame seed Dehulled sesame seed can be toasted (dry roasted) to give it an enhanced nutty flavour and a light tan to brown colour. A.3 Countries of origin Commonly traded origins of sesame seed are Guatemala, Mexico, Nicaragua, El Salvador, Honduras, Venezu
36、ela, United States of America, India, China, Indonesia, Philippines, Sudan and Ethiopia. Annex B (normative) Preparation of samples for chemical tests Mix the laboratory sample thoroughly and take a test sample of sufficient quantity for each test. Ensure that all material in the test sample passes
37、a 1.00 mm square aperture test sieve conforming to BS 410 : 1986, grinding the test sample as necessary in accordance with BS 4540 : Part 2 : 1982. Annex C (informative) Additional information C.1 General Further requirements may be specified in purchase contracts for sesame seed. They are generally
38、 relevant to the ultimate use of the product. Those commonly used are given in C.2 to C.5. C.2 Bulk index The bulk index (used to assess the amount of material required to fill a retail pack) is expressed generally in millilitres per 100 g (carried out by a mutually agreed method). C.3 Particle size
39、 (mesh) Particle size is expressed generally as a percentage by mass that passes through a specified test sieve conforming to BS 410. C.4 Microbiological details Generally these are specified when the material is required for further processing. Microbiological counts may be reduced by the use of le
40、gally permissible treatments (see item a)4) of clause 8). C.5 Infestation Sesame seeds are not prone to infestation but it can arise. In cases of infestation, bromomethane (methyl bromide) or other recognized fumigants are effective, with subsequent cleaning or sifting if necessary. C.6 Trace metals
41、 Levels of lead, arsenic and tin in herbs and spices are currently controlled by the Lead in Food Regulations 1979 (SI 1979 No. 1254) 2, the Arsenic in Food Regulations 1959 (SI 1959 No. 831) 3 and the Tin in Food Regulations 1992 (SI 1992 No. 496) 4 respectively. The recommended levels of copper an
42、d zinc are given in the Food Standards Committee Reports 5, 6. These levels are shown in table C.1.
