Potato chips are widely loved by people because of their convenience, fast taste, long shelf life and long shelf life. Potato chips are fried and dry foods, which are easily oxidized and deteriorated, and are damp and mildewed. Once oxidized, fatty acids are easily produced, resulting in excessive acid value. However, moisture will affect the taste of potato chips, leading to deterioration and even mildew, which may cause quality during consumption. ACCIDENT. Therefore, it is particularly important for the detection of barrier properties of potato chip packaging.
The so-called barrier properties of potato chips refer to the barrier effect of packaging materials on permeates such as gases and liquids. Barrier testing includes testing of gas (oxygen, nitrogen, carbon dioxide, etc.) and water vapor transmission properties. Barrier performance is an important factor affecting the quality of shelf life of products. It is also an important reference for analyzing shelf life. It can analyze and solve problems such as oxidative deterioration and mildew mildew caused by oxygen or water vapor sensitivity.
(1) Oxygen barrier performance test of potato chip packaging bag:
Potato chips are a kind of fried food, and the oil is mainly animal or vegetable fat and oil, which is easily oxidized and deteriorated, and is easy to produce fatty acids, resulting in excessive acid value. In the storage process, the time is too long, the temperature is too high, and the oxygen barrier performance of the packaging material is not good, which may cause the potato chips to be exposed to excessive oxygen and cause deterioration. This requires the enterprise to strictly control the oxygen barrier properties of the packaging materials. control.
We can use the GPT-301 differential pressure gas permeation instrument produced by Saicheng Electronic Technology Co., Ltd., which meets the test method specified in the food packaging inspection standard and implements the GB/T 1038-2000 plastic film and sheet gas permeability. The test method pressure difference method standard can help enterprises to control the transmittance index of oxygen, carbon dioxide, nitrogen and other gases. The gas permeability and solubility coefficient of the sample can be measured at the same time. The test range can be expanded as needed to meet the requirements of large transmittance test. The data can be fitted at any temperature to easily obtain the test results under extreme conditions.
(2) Detection of water and moisture resistance of potato chip packaging bags:
Water blocking and moisture proof are important means to solve the moisture and mildew of potato chips. The wetting performance test of food packaging materials generally adopts the weighing method test principle. Based on the cup method test principle, the W\601 water vapor transmission rate tester produced by Saicheng Technology is a water vapor transmission rate tester for film samples. It is suitable for plastic film, composite film and other films. Determination of water vapor transmission rate of sheet materials and various materials such as medical and building materials. Through the measurement of water vapor transmission rate, the technical indicators of control and adjustment materials are achieved to meet the different needs of product applications. Intermittent weighing according to the standard requirements, the system automatically clears before each measurement to ensure the uniformity and accuracy of the data. Three (six) samples can be tested simultaneously in a single test. The wetting cup is lifted and weighed by the cylinder. , the data is accurate and reliable
The above content mainly introduces the barrier performance test of potato chip packaging. After ensuring this index, it is necessary to carry out quality on other aspects of packaging such as packaging sealing, heat sealing performance, mechanical properties and printing quality. Control to ensure the reliability of product quality.
