Do rice dumplings need to be tested for moisture? How to detect

Need. Zongzi fillings are tested for physical and chemical indicators.

At present, the national standard has adjusted the requirements for loss on drying index and protein content, and deleted the acid value index; In terms of physical and chemical health indicators, the requirements for peroxide value and microbial indicators were revised to "should meet the requirements of relevant national food safety standards".

The loss on drying index reflects the moisture status of the zongzi. The previous standard requirement was "less than or equal to 55%", but now the standard plan is adjusted to "less than or equal to 65%". For example, Shanxi millet dumplings, because the particles of millet are small and the water absorption surface is larger, if it is according to the original standard, it is difficult to meet the standard.

The same principle applies to steamed dumplings in Guangdong, according to the traditional process, steamed dumplings should be boiled in water for seven or eight hours in a row, so that the dumplings absorb water very well. "The moisture content of zongzi fillings will directly affect the quality of zongzi and indirectly affect the interests of merchants.

How to test the dry weight loss index of zongzi filling.

At present, most businesses use the national standard oven method test, this method of testing time is slow, cumbersome operation, need professional inspectors to operate, if not careful, the test results will be affected, in view of this situation, Shenzhen Guanya moisture meter technology **** according to the principle of the national standard oven method, research and development and production of a new type of rapid moisture detection instrument - zongzi filling rapid moisture detector.

The instrument adopts an automatic weighing system imported from Germany to ensure accurate weighing; Compared with the international oven method, the special ruby heating light source can dry the sample evenly and gently at high temperature, and the sample surface is not easy to be damaged, and its detection results are consistent with the national standard oven method, which is substitutable, and the detection efficiency is much higher than that of the oven method. Intelligent operation, the general sample can be measured in only a few minutes, and it is a new type of intelligent rapid detection instrument.

The moisture content of zongzi has little to do with the length of shelf life. It's nothing more than how soft and hard the taste is. In order to control the moisture, it is necessary to determine the variety of rice, the soaking temperature and the time.

Boiling time. For example, the shelf life of high-temperature sterilization is only related to the control and sterilization value of the initial bacteria. Guanya zongzi moisture analyzer.

Halogen moisture meter|Halogen Rapid Moisture Meter|Halogen moisture analyzer is a new type of rapid moisture detection instrument newly developed by our company. Halogen moisture meter|Halogen Rapid Moisture Meter|Halogen moisture analyzer adopts the most advanced weighing system in the world [electromagnetic balance sensor]. It is characterized by accurate and reliable weighing, fast and clear display, automatic detection system, simple automatic calibration and overload protection.

It is a new type of rapid moisture detection instrument.

The ring-shaped halogen lamp ensures that the sample is evenly heated, making it easy to operate and accurate to measure. While measuring the weight of the sample, the instrument adopts the halogen heating method of the annular tube to dry the sample quickly, during the drying process, the moisture meter continuously measures and displays the moisture content lost by the sample instantly%, and after the drying procedure is completed, the final measured moisture content value is locked and displayed. Compared with the international oven heating method, halogen heating can dry the sample evenly and quickly at high temperature, and the sample surface is not easy to be damaged, and its detection results are consistent with the national standard oven method, which is substitutable, and the detection efficiency is much higher than that of the oven method.

Intelligent operation, the general sample can be measured in just a few minutes. The instrument is simple to operate, accurate to test, the display part of the use of LCD screen - to make the screen more clear and bright, the indication value is clearly visible, can display the moisture value, sample initial value, final value, measurement time, temperature initial value, final value and other data, and has the function of connecting with the computer, printer, in line with GLP specifications of the print data output. Usage:

Halogen moisture meter|Halogen Rapid Moisture Meter|Halogen moisture analyzer can be widely used in all industries that need to quickly determine moisture, such as medicine, grain, feed, seeds, rapeseed, dehydrated vegetables, tobacco, chemical, tea, food, meat and textile, agriculture and forestry, papermaking, rubber, plastic, textile and other industries in the laboratory and production process. At the same time, to meet the requirements of solids, granules, powders, colloids and liquid moisture content determination, Shenzhen Houwang Electronic Technology Co., Ltd. has always been determined to provide users with multi-purpose, multi-performance high-quality products, for you to create a fast, accurate, value-for-money moisture analyzer perfect model.

The operation is very simple, you only need to take a sample and put it into the WL-600 moisture detector, press the test button, the instrument will automatically test the alarm, display the moisture value, and the result will be available in 3-5 minutes, very fast, the operation is not cumbersome.

One is the Karl Fischer method, and the other is the drying method: it can be detected in an oven, and the other is tested with a rapid moisture detector.

With the importance of food safety, the moisture detection of meat sausages is an important link, and red sausages generally need to be tested for moisture when leaving the factory.

Take ham sausage as an example: water (% premium (70) excellent (67) regular (64) starch-free (70).

For meat products, the moisture is usually tested in an oven, which takes a long time. The halogen rapid moisture meter can detect efficiently and accurately. Please contact us for details.

From incoming inspection, to quality control, production and storage, to new product development, moisture determination plays an important role in all aspects of the food industry. In almost all cases, prepared ingredients have the optimal moisture content to ensure the best taste, consistency, appearance and shelf life. Based on the MS-A-100 series microwave moisture analyzer food moisture content detection technology scheme, it can measure the overall moisture and average moisture of candy, coffee, preserved fruit and other foods in real time, and can measure the water content of various types of candy, coffee, preserved fruits and other foods.

Our country has strict standards for moisture content in the factory quality standards for candy, coffee, preserved fruits and other foods, which is also an important basis for the settlement, pricing and quantification of these products. Therefore, it is very important to choose a good moisture meter for candy, coffee, preserved fruit and other food production enterprises.

Zongzi should be placed in the freezer, heated and cooked thoroughly before eating, not to reduce moisture, and not to let people eat raw and cold food, which is good for the body.

First of all, what are the characteristics of your sample, if it is a volatile sample, it is recommended to use the chemical SFY-102S trace moisture meter, and the non-volatile sample can be tested by the physical WL-600 moisture detector.

1. If it is a new oil, there is a clear provision in the national standard of the product, and the water content of the lubricating oil is a trace, that is, it is lower.

2. If it is a lubricating oil in operation, if the moisture is obviously abnormal, the presence of moisture will gradually deteriorate and fail the lubricating oil, and then cause serious consequences to the equipment. Testing the moisture can help diagnose whether the oil can continue to be used, and work ahead to prevent lubrication accidents and eliminate hidden dangers.

The moisture in "water-mixed gasoline" will accelerate the corrosion of metals by organic acids, and long-term use can lead to accelerated damage to oil pumps, gasoline filters, fuel injectors, and even engines. Huayan Testing is a professional oil testing organization, and the testing items include: moisture, ash, mechanical impurities, octane number, pour point, etc.
