8、BS 7087 has been prepared by Technical Committee AW/7 and is 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 sub
9、stantially related to, the corresponding international standards 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 St
10、andards implementing those international standards are therefore being progressively withdrawn and replaced by Parts of BS 7087 for herbs and spices ready for food use.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 qual
11、ity with implications for the microbiological quality of dried 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 spic
12、es may need to be greater than the one in ten primary dilution 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 immu
13、nity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pages i and ii, pages 1 to 4, an inside back cover and a back cover.

30、 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 with third party certification of conformity. 6 Chemical composition NOTE. For information on trace
31、 metal contents in these products see C.6. 6.1 Whole dill seed The chemical composition of whole dill seed shall conform to the relevant requirements specified in table 1. 6.2 Dill leaves (dill weed) The chemical composition of dill leaves shall conform to the relevant requirements specified in tabl
32、e 1. 6.3 Ground dill The chemical composition of ground dill shall conform to the relevant requirements specified in table 1. 7 Packaging and storage To avoid condensation, a container that is permeable to air shall be used for the packing and storing of bulk material. NOTE 1. Hessian, hessian sacks
33、 with a thin gauge inner plastics sack or multi-ply paper sacks (sometimes plastics-lined) or woven plastics sacks are most commonly used. NOTE 2. Bulk material should be stored in a clean, dry, ventilated room, free from infestation and not exposed to direct sunlight. NOTE 3. For those packs that d
34、o 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 board, glass jars, lever lid tins and polyethylene bags in boxes). NOTE 4. Dill weed fades during storage and should be protec
35、ted from light. 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 whole or ground dill, the following information shall be marked
36、. 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 dill seed/dill leaf; 2) country of origin of crop; 3) net mass (in g or kg); 4) a statement of any special treatment, e.g. fumigation or irradiation;
37、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 7087/29 or BS 7087 : Part 29 : 1996 1) . b) For retail material: 1) the name o
38、f the food, e.g. dried ground dill; 2) the number of this Part of this British Standard, i.e. BS 7087/29 or BS 7087 : Part 29 : 1996 1) . NOTE 3. Reference should be made to those instruments currently in force.BS 7087 : Part 29 : 1997 BSI 1997 3 Annexes Annex A (normative) Description of dried, who
39、le dill seed, dill leaves and ground dill A.1 Whole dill seeds The complete seed consists of a broadly oval schizocarp consisting of 2 mericarps attached to a divided carpophore. In practicality, the seed splits on drying and the commercial product consists of seed as mericarps. These are approximat
40、ely 2.5 mm to 5 mm long and 1.5 mm to 2.5 mm wide and roughly oval in shape. In cross section the seeds have a flat or concave under-surface and pronouncedly convex upper surface, which is the seed. The convex seed surface has three pronounced longitudinal mid/light brown ridges upon them, the seed
41、colour being brown/dark brown/ dark brown-green, dependent on origin, sub-species and crop conditions. The periphery of the mericarp is a lighter colour as are the ridges. Indian dill seed Anethum sowa (Kurz), a species native to northern India is characterized by seeds that are larger, flatter and
42、tan-coloured with a yellow coloured frame around the edge. A few seed stalks (pedicels) are invariably present. It is desirable that these be largely removed for premium material, as far as practicable. A.2 Dill leaves These are often known as dill weed or dill tips. The leaves are feather-like, fin
43、ely divided and delicate and long and thin. They are approximately 5 mm to 15 mm long and 0.15 mm to 0.35 mm wide and roughly circular in cross section. The colour varies between dark green to bright mid-green to yellow green dependent on sub-species, origin and drying. The leaves are broken in the
44、drying and rubbing process and dill leaves are generally sold in the form of broken leaves typically 2 mm to 7 mm long. Freeze-dried dill leaves are a common alternative to the air-dried material. The latter have improved colour (midbright green) and a higher bulk index. A.3 Ground dill Ground dill
45、is produced by grinding whole dill seed with no additions. The colour is dependent on origin, sub-species and crop conditions and varies from tan brown via green brown to mid/dark brown. A.4 Countries of origin The commonly traded origins of dill are variable dependent on the portions of the plant u
46、sed. For dill seed the commonly traded origins are India, China, Spain, Germany and the Eastern European region. Dill seed imported from India is usually Anethum sowa whilst Anethum graveolens is imported from Egypt and California. For dill leaves (dill weed) the commonly traded origins are France,
47、USA, Germany, Egypt, Denmark and the Eastern European region. NOTE. The whole plant is aromatic and oil extraction from the seeds/leaves also occurs. Annex B (normative) Preparation of samples for chemical tests Mix the laboratory sample thoroughly and take a test sample of sufficient quantity for e
48、ach test. Ensure that all material in the test sample passes 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 specif
49、ied in purchase contracts for all types of dill. They are generally 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 (mesh) Particle size is often quoted for ground dill. Particle size is expressed generally as a percentage by mass of material that passes through a specified test sieve conforming to BS 410. C.4 Microbiological det
