The spicy strips are spicy and attractive. Only the spicy strips that pass the test can be deeply rooted in the hearts of consumers. The spicy strips (also known as spicy slices) are a kind of snack. The main raw materials are wheat flour and chili, and there are a large number of food additives. There is no unified production standard. The spicy strip manufacturers on the market generally produce according to landmarks, and the implementation standards are generally DB41/T515-2007 and GB2760.
While spicy strips have become a popular snack food, the product quality control during the production process of spicy strips cannot be ignored. Today we will introduce the physical and chemical testing items that must be inspected for spicy strips: moisture content and water activity. .
1. Moisture content of spicy strips:
The influence of moisture content on the hardening of spicy strips: Too high or too low water content for mixing noodles will cause the puffed strips of spicy strips to be stored It hardens after some time. Depending on the products produced by the company, the moisture content of the finished spicy strips is generally within 35%.
2. Rapid moisture detection method of spicy strips:
1. Turn on the power and turn on the switch, set the drying heating temperature and heating time to automatic, and the result is expressed as 0-100
p>2. Open the sample chamber cover, take the triangular bracket, handle bracket, and sample plate and place them on the weighing bracket of the moisture analyzer in sequence, and set them to zero
3. Take out the sample, spicy strips Chop or pulverize, place the sample on the sample plate, take out the sample plate, spread the sample evenly on the sample plate, and then return it to the sample chamber.
4. Cover the sample chamber cover and press the "Start" test button
5. After drying is completed, the moisture content will be read on the touch screen
6. If equipped with a printer, press the print button to print the moisture content.

4. Water activity of spicy strips and its detection method:
Since the concept of water activity was proposed in 1957, it has been widely used in the preservation of spicy strips. Water activity is defined as the active portion, or free water, of the water content in a substance. Water activity is considered an important indicator of product stability. By controlling water activity at low levels through appropriate methods (including drying, chemical combination of large amounts of sugar or salt with water) to achieve long-term preservation of the product, controlling water activity not only controls the growth of microorganisms, but also improves the chemical and physical properties of the product. Very well preserved. The water activity of spicy strips is kept within 0.7 and is suitable for storage.

6. Description of Spicy Tiao Water Activity:
Especially when the weather is particularly hot, the workshop production of products, any If there is mold in the location, the product will be contaminated. Those mold spores that are invisible to the naked eye will spread under control and fall on the product. In addition, if the moisture and activity of the product are not controlled well, the spicy strips will easily become moldy
GYW-4 Latiao Water Activity Tester has obtained the "Moisture and Activity Measurement Value Acquisition and Processing System Software Copyright", using a 7-inch high-resolution LCD large screen, full touch operation mode, and real-time display The data changes in the sample simultaneously display the changes in the test curve of the sample in real time, and the entire test process is completed automatically. After the analysis is completed, the instrument screen automatically locks the final data, prompts and alarms. No personnel is required to care and maintain the experimental process. After the experiment, a special micro-printer prints out the effective data of the test in real time for long-term storage.
