CO, the CO of 15.11067vol%2, the C of 0.02525vol%3H6, the C of 0.01748vol%3H8。
The cup of coffee, which is surveyed, feels most important for the quality of coffee, has usually contained the bitter taste to coffee, acid
The pursuit of the indexs such as taste, texture, sweet taste, flavor, rear taste, clean degree and balance (wind-acid-hardship), is comment most important to coffee
Price card is quasi-.Therefore, the result that cup is surveyed is able to reflect out the quality of coffee.In the evaluation result shown in table 1-3,0-5 distinguishes table
Show and never feels, to feeling strong.
It can be seen that from above result by the way that the coffee of grinding to be sealed to the coffee product A obtained in time, even if
It places 3 months, the quality of Fresh Ground Coffee can still be maintained.
Specifically, the bitter taste of the coffee product A in table 1 is 2, and the bitter taste of the Fresh Ground Coffee in table 2 is 3, is closer to；
Tart flavour is 3 in table 1, and the tart flavour of the Fresh Ground Coffee in table 2 is 4；Texture in table 1 is 4, and the texture in table 2 is 3；Sweet tea in table 1
Taste is 3, and the sweet taste in table 2 is 3；Flavor in table 1 is 4, and the flavor in table 2 is 3；Rear taste in table 1 is 4, the rear taste in table 2
It is 4；Clean degree in table 1 is 4, and the clean degree in table 2 is 3；Balance (wind-acid-hardship) in table 1 is 3, and the balance in table 2 is
4.For can be seen that on the whole from above comparison, the cup that coffee product A preferably maintains Fresh Ground Coffee B, which is surveyed, to be felt, together
When due to grinding after long-time place so that the texture of coffee is improved to 4, flavor is improved to 4, and clean degree is also promoted to 4.
Fresh Ground Coffee maintains preferable balance (wind-acid-hardship) since its freshness is higher.From table 3 it can be seen that commercially available
Coffee can not obtain higher marking, only be able to maintain that common cup surveys result.
Embodiment 2
The present embodiment studies the relationship between packaging time and gas pressure.It repeats to prepare coffee product A's in embodiment 1
Method, except that the time packed after variation grinding.In the evaluation result shown in table 4,0-5, which is respectively indicated, never to be pressed
Into hermetic bag, pressure is big and sufficiently expands for power.Index 0 indicates that hermetic bag is not propped up by gas.Index 1 indicates hermetic bag
Middle pressure very little, hermetic bag are not obviously propped up, but when with hand densification envelope, can be felt with the presence of inflation.Index 3
Indicate that pressure is appropriate in hermetic bag, after expanding, when with hand densification envelope, with certain elasticity.Index 4 indicates close
Pressure is larger in envelope, relatively harder when with hand densification envelope after expanding, and has more small.Index 5 indicates
Pressure is very big in hermetic bag, after expanding, when with hand densification envelope, could difficultly depress very much, can with what is be bursting at the collision
It can property.In practical application, obtain the case where pressure is 3 or 4 be it is proper, pressure is less high, and having for product is preferable
Appearance and feel, and the danger that do not burst.More preferably use the case where pressure is 3, in this case, product
Appearance, feel and pressure reach optimum balance.
