What is BS 6986-2-Determination of free-flow and compacted bulk densities of instant tea about?
BS 6986 is a British standard on analysis of instant tea that discusses the determination of free-flow and compacted bulk densities of instant tea to calculate the effects on the processibility, usability, and quality of instant tea.
BS 6986-2 is the second part of the BS 6986 series that specifies two methods for the determination of the bulk density of instant tea:
- Free-flow bulk density
- Compacted bulk density
Free-flow bulk density (of instant tea) is the ratio of the mass of instant tea to the volume it occupies after it has been tipped freely into a container under specified conditions it is expressed in grams per millilitre (g/ml).
compacted bulk density (of instant tea) is the ratio of the mass of instant tea to the volume it occupies after it has been subjected to a few taps (usually 100) under specified conditions it is expressed in grams per millilitre (g/ml)
Who is BS 6986-2-Determination of free-flow and compacted bulk densities of instant tea for?
BS 6986-2 on the determination of free-flow and compacted bulk densities of instant tea is useful for:
- Instant tea manufacturers
- Instant tea test personnel
- Packaging departments
- Food technologists
- Food laboratories
- Food health and safety departments
Why should you use BS 6986-2-Determination of free-flow and compacted bulk densities of instant tea?
Bulk density is defined as the ratio of mass to volume. The volume of a given sample of instant tea varies according to its history of handling, due to compaction (reversible) and powder breakdown (irreversible) effects.
Knowledge of the bulk density of instant tea is essential to trade in that commodity for it determines the volume occupied by a given mass and hence is a key factor in filling jars correctly for retail sale, and for controlling the mass of instant tea delivered from vending machines.
BS 6986-2 provides you with guidance on apparatus, sampling, procedures, free-flow bulk density and compacted bulk density methods, expression of results, method of calculation and formula, test report, etc.
The methods and procedures provided by BS 6986-2 assist you to determine the bulk density of instant tea, enhancing the quality of the beverage and increasing the shelf life of instant tea.
With obedience and compliance to BS 6986-2, you can enhance instant tea’s effectiveness and efficacy and manufacture a standardized product.
