Foreword

ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies

(ISO member bodies). The work of preparing International Standards is normally carried out through ISO

technical committees. Each member body interested in a subject for which a technical committee has been

established has the right to be represented on that committee. International organizations, governmental and

non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the

International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.

International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.

The main task of technical committees is to prepare International Standards. Draft International Standards

adopted by the technical committees are circulated to the member bodies for voting. Publication as an

International Standard requires approval by at least 75 % of the member bodies casting a vote.

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent

rights. ISO shall not be held responsible for identifying any or all such patent rights.

ISO 8455 was prepared by Technical Committee ISO/TC 34, Food products, Subcommittee SC 15, Coffee.

This second edition cancels and replaces the first edition (ISO 8455:1986), which has been technically revised.

Green coffee — Guidelines for storage and transport
1 Scope

This International Standard gives guidelines for conditions aimed to minimize the risks of infestation,

contamination, and quality deterioration of green coffee (also known as raw coffee) in bags and “big-bags”

(see Note), in bulk and in silos, being the subject of international commerce, from the time of its packing for

export until the time of its arrival in the importing country.

NOTE The term “big bag” refers to modern flexible containers in woven plastics fibre, able to contain about 1 000 l of

loose coffee beans.

4 Conditions of putting into storage
4.1 Quality characteristics for storage

4.1.1 Green coffee before storing should be free from signs of insect infestation, rodent contamination,

mould and other contamination (determined in accordance with ISO 4149 and ISO 6667 as necessary).

Coffee beans should be sufficiently dry so as not to be unnecessarily vulnerable to subsequent moulding, but

not so dry as to cause unnecessary bean breakage. Coffee moisture content (see the next paragraph) shall

always be determined, in accordance with ISO 1446 or ISO 6673. The method used should be indicated.

Since upper and lower acceptable moisture limits depend on the method and apparatus used for

measurement, they should be established by practical experience and made explicit in specifications and

contracts.

4.1.2 The bags, “big bags”, containers or silos in which the green coffee is to be stored should be inspected

before use to ensure that they are odour free, free from signs of insect infestation, rodent contamination and

other contamination, as well as being physically sound.
4.2 Putting green coffee into storage

4.2.1 Green coffee intended for storage, after being packed for export should be moved with minimum

delay to well-ventilated, well-maintained storage areas or facilities. The temperature and relative humidity of

the air surrounding bagged coffee in store should be sufficiently constant and low enough (as determined by

practical experience) to ensure that the original quality of the coffee is preserved throughout the duration of

storage.

4.2.2 All inland transport vehicles should be inspected by a person in authority before loading green coffee,

to ensure that they are in a good sanitary condition, defined as the absence of filth (fragments of insects, hair

of rodents, etc.), mould, chemical contamination or other contamination.

4.2.3 During inland transportation to and from storage facilities, the bagged green coffee should be

protectively covered to prevent stray contamination and weather damage. Green coffee should be especially

protected from rehydration. Airproof sealing of non-transpiring containers can lead to condensation, and

should be avoided.
5 Conditions for storage
5.1 Location of the warehouse

Warehouses should not be built in places where cold air accumulation can occur; therefore low and humid

areas should be avoided. They should be built on a high ground level, and wall and foundations should be

waterproof insulated, in order to exclude external wetness.

The warehouse should be oriented in east-west, north-south direction, with the shorter wall facing the sunny

side, in order to save on insulation; consequently, it is preferred that the length faces east-west. The doors of

the warehouse should never face a direction from which winds that might be harmful to the quality of the

coffee are expected.
5.2 Surroundings of the storage facilities
5.2.1 Spills should be cleaned up promptly.
5.2.2 Waste, dunnage, and refuse should be removed promptly.

5.2.3 Equipment should be stored in such a manner that it cannot provide harbourage for rodents, insects,

or birds.
