Embodiment 1

[0027] step 1:

[0028] (1) Take 20 aluminum bottles of the same batch (capacity is 350ml) from the production line, wash them three times with pure water that meets the first-grade water in the analytical laboratory, and then add 3.5% ethanol aqueous solution (food grade anhydrous water) at 60°C (prepared by ethanol plus first-grade water in the analysis laboratory) as the content simulation liquid, the content is added to a distance of 5mm-6mm from the bottle mouth, automatically sealed by the capping machine, and then put into an ultrasonic extraction constant temperature device that has been heated to 60°C. Incubate at 60°C for 35 minutes under the action of 40KHz ultrasonic waves, and carry out constant temperature extraction;

[0029] The ultrasonic extraction constant temperature device is provided with the top of the vertical rotating shaft, and the capped aluminum bottle containing the simulated liquid of the content is vertically fixed on the rotating shaft, rotates ...

Embodiment 2

[0050] Select 20 aluminum bottles from the same batch as in Example 1, rinse them three times with pure water conforming to the first-grade water in the analytical laboratory, add more than 300mL of beer of the standard process of the brewery, reach the bottle mouth at 5mm-6mm, and seal the cap Afterwards, according to the method and steps of Example 1, extraction and aging were carried out and sensory evaluation was carried out. The obtained sensory scores are shown in Table 6. The curing quality of the inner coating is grade II, which is consistent with the evaluation of the content simulation liquid in Example 1, indicating that the content simulates The liquid can simulate the actual beer content.

Embodiment 3

[0054]Select 20 aluminum bottles of the same batch as in Example 1, rinse them three times with pure water meeting the first-grade water in the analytical laboratory, add 3.5% ethanol to the 5mm-6mm of the bottle mouth, and place the bottle at room temperature (25°C) after sealing. ) were stored for 3 months, 6 months, 12 months and 14 months respectively, and then scored by means of the sensory evaluation of the steps (3) and (4) of Example 1, the sensory scores are as follows in Table 7, the curing quality of the inner coating The grade is II, which is consistent with the evaluation results of Example 1 using ultrasonic constant temperature extraction and accelerated aging, indicating that ultrasonic constant temperature extraction and accelerated aging can simulate the shelf life under normal temperature storage.

Abstract

The invention provides a method for predicting aluminium bottle internal coating solidification quality based on sensory evaluation. According to the method, the aluminium bottle internal coating solidification quality is predicted based on sensory evaluation. With a 3.5% volume fraction ethanol aqueous solution as a standard content object, through supersonic wave extraction and constant temperature acceleration aging, the microscale flavour substance migration in an aluminium bottle internal coating is accelerated, and then the sensory evaluation is carried out. Through the established prediction model of the invention, the sensory evaluation score of a sample can be converted into the aluminium bottle internal coating solidification quality, compared with a traditional package beer sensory evaluation method, the method of the invention has the advantages of rapidness and convenience, high efficiency and good rapidity and is suitable for being popularized in the aluminium bottle industry.

Description

technical field [0001] The invention relates to a method for predicting the curing quality of an inner coating of an aluminum bottle based on sensory evaluation. Background technique: [0002] The aluminum bottle adopts a single-piece aluminum can body structure, no welds, lightweight, and environmentally friendly. Compared with glass bottles, aluminum bottles have extremely high shading performance and have the effect of isolating light, which can prolong the shelf life of packaged products and stabilize the quality. Compared with glass bottle packaging, aluminum bottles also have obvious advantages in the display of new technologies such as the compactness of printed graphics, color difference display effects, and embossed effects on the surface of aluminum bottles. At present, aluminum bottles are mainly used in the packaging fields of high-end beer, pharmaceuticals, food and beverages, etc. It is the development trend of international high-end beer packaging, and the ma...
