ISO 18794:2018 defines terms relating to coffee sensory analysis. ISO 18794:2018 covers definitions applicable to green, roasted and ground coffee, coffee extracts and soluble coffee. The terms are given under the following headings: a) basic terms of sensory analysis; b) generic terms in the sensory assessment of coffee; c) terminology relating to coffee-specific odours and tastes; d) terms commonly used in sensory assessment of coffee by practitioners.

This Technical Specification specifies a method for the determination of acrylamide in cereal-based products, potato-based products and coffee by gas-chromatography mass spectrometry (GC-MS).
The method has been single-laboratory validated via the analysis of spiked samples (French fries (uncooked), bread, water biscuit, infant cereal, biscuit, green coffee, roast coffee and instant coffee), ranging from 30 μg/kg to 1 500 μg/kg acrylamide.
The results from the single laboratory validation were...view more

This European Standard specifies a method for the determination of furan in coffee and coffee products with headspace-gas chromatography-mass spectrometry (HS-GC-MS), see [1] and [2]. Coffee products in the scope of this method are extracts which have been spray-dried, agglomerated or freeze-dried. The method has been validated in an interlaboratory study via the analysis of naturally contaminated samples of spray-dried coffee, freeze-dried coffee and roasted coffee ranging from 263,8 µg/kg to 2...view more

This European Standard specifies a method for the determination of acrylamide in bakery ware such as bread, toasted bread, crisp bread, butter cookies, and biscuits, as well as potato products such as potato chips, potato crisps, and potato pan cake and roasted coffee, by liquid chromatography in combination with electrospray ionization and tandem mass spectrometry (LC-ESI-MS/MS). This method has been validated in an interlaboratory study via the analysis of both naturally contaminated and spike...view more

This International Standard specifies a routine method for carrying out size analysis of green coffee by manual and machine sieving using laboratory test sieves.

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.

This International Standard specifies a procedure for adjustment and subsequent calibration of moisture meters for green coffee beans with reference samples (RSs). The RSs are green coffee beans of various moisture contents, determined by a standard method (ISO 6673). NOTE This method of determining the loss in mass can be considered, by convention, as a method for determining the water content and can be used as such by agreement between the interested parties. This International Standard is ap...view more

ISO 4150:2011 specifies a routine method for carrying out size analysis of green coffee by manual and machine sieving using laboratory test sieves.

This International Standard provides a chart which lists the main five different categories of defects which are considered to be potentially present in green coffee as marketed throughout the world, whatever its species, variety, and after-harvest processing (wet or dry).
This chart shows the influence of such defects on the loss of mass and on the sensorial concern by using the coefficients (0), (0,5) and (1). Each defect is given one of these values depending on how seriously it affects the ...view more

This International Standard specifies a method for the determination of the loss in mass at 105 °C of green coffee.
It is applicable to decaffeinated and non-decaffeinated green coffee as defined in ISO 3509.
This method of determining the loss in mass can be considered, by convention, as a method for determining the water content and can be used as such by agreement between the interested parties, but it gives results which are lower, by about 1,0 %, than those obtained with the method descri...view more

This International Standard gives guidance on methods to be used to describe green coffee for sale and purchase, and is based on the terms of contract used in the international coffee trade.
It also recommends procedures for sampling, packing, marking, storage and shipping of green coffee. It is applicable to green coffee as defined in ISO 3509.

This International Standard specifies methods for the olfactory and visual examination and for the
determination of foreign matter and defects in green coffee from all origins, in order to assess conformity with a specification or a contract. These methods can also be used for determining one or more of the characteristics of green coffee with an impact on coffee quality for technical, commercial, administrative and arbitration purposes, and for quality control or quality inspection.

This International Standard specifies a high performance liquid chromatography (HPLC) method for the determination of the caffeine content of: green coffee; roasted coffee; soluble coffee, regular and decaffeinated; and mixed instant coffee products (e. g. coffee/chicory mix or cappuccino-type coffee drink).

This International Standard specifies a method for the roasting of green coffee, grinding the roasted coffee, and the preparation — from the ground coffee — of a beverage to be used in sensory analysis.
The sensory analysis carried out following this preparation may be used to determine the acceptance or rejection of a shipment of coffee, subject to agreement between the parties concerned. Generally, the sample will require a light roast for assessment of defects, and a medium roast for assessm...view more
