Embodiment 1

[0065] Select first-grade soybean oil, and detect its initial acid value to be 0.06. On the 5th day, an oil sample was taken out to detect an acid value of 0.10, which was 0.04 higher than the initial value; another oil sample was taken out on the 7th day to detect an acid value of 0.10, which was 0.04 higher than the initial value.

[0066] Take the oil samples from the above-mentioned oil tank and put them into 900ml PET bottles, put them into 10 bottles in total, press the lids on and place them at room temperature, take one bottle every two months to test the acid value, the results are as follows:

[0067] placement time February April June August October December 14 months 16 months 18 months acid value 0.08 0.09　 0.11　 0.12　 0.12　 0.13　 0.15　 0.15　 0.16　

[0068] △2=0.04<0.06, △3=0.04<0.2 The acid value of this batch of first-grade soybean oil is stable, and it has not exceeded the national standard (0.2) during the 18-month...

Embodiment 2

[0070] Select first-grade soybean oil, and detect its initial acid value to be 0.06. On the 5th day, an oil sample was taken out to detect an acid value of 0.10, which was 0.04 higher than the initial value; another oil sample was taken out on the 7th day to detect an acid value of 0.14, which was 0.08 higher than the initial value.

[0071] Take the oil samples from the above-mentioned oil tank and put them into 900ml PET bottles, put them into 10 bottles in total, press the lids on and place them at room temperature, take one bottle every two months to test the acid value, the results are as follows:

[0072] placement time February April June August October December 14 months 16 months 18 months acid value 0.09 0.12 0.13 0.15 0.15 0.17 0.18 0.19 0.19

[0073] △2=0.04<0.06, △2=0.08<0.2, the acid value of this batch of first-grade soybean oil is stable, and has not exceeded the national standard (0.2) during the 18-month shelf lif...

Embodiment 3

[0075] Select first-grade soybean oil, and detect its initial acid value to be 0.06. On the 5th day, an oil sample was taken out to detect an acid value of 0.12, which was 0.06 higher than the initial value; another oil sample was taken out on the 7th day to detect an acid value of 0.18, which was 0.12 higher than the initial value.

[0076] Take the oil samples from the above-mentioned oil tank and put them into 900ml PET bottles, put them into 10 bottles in total, press the lids on and place them at room temperature, take one bottle every two months to test the acid value, the results are as follows:

[0077] placement time February April June August October December acid value 0.16 0.18　 0.19　 0.20　 0.20　 0.22　

[0078] △2=0.06=0.06, the acid value of this batch of first-grade soybean oil exceeds the national standard within 8 months, so it cannot be filled as first-grade oil.

Abstract

The invention discloses a device and a method for predicting acid value stability of edible oil. The device comprises a detection device body, a controllable humidifier and an air filter, wherein the controllable humidifier is connected to the detection device body; the air filter is arranged on the detection device body; a mixer and a reactor connected with the mixer through an air pipe are arranged on the detection device body; and moisture generated by the controllable humidifier and air filtered by the air filter are introduced into the mixer to be mixed, and the mixed moisture is introduced into a reactor filled with an oil sample by virtue of the air pipe. According to the device and the method disclosed by the invention, the acid value stability in shelf life of the product can be rapidly predicted, an effect of alarming problem products in advance can be achieved, and the problem products are prevented from flowing into the market, so that food safety incidents are avoided.

Description

technical field [0001] The invention relates to the technical field of edible oil detection, in particular to a device and method for predicting the acid value stability of edible oil. Background technique [0002] The quality of edible oil is related to the lives of thousands of households. Acid value AV and peroxide value PV are important quality and safety indicators of edible vegetable oil. During storage, edible vegetable oil is susceptible to various factors such as oxygen, moisture, light, and temperature. Oxidation or hydrolysis leads to rancidity, and the stability of oils (that is, the characteristics of oils that can withstand the influence of the above factors and maintain the same or little change in acid value and peroxide value) is also an important indicator to measure the quality of oils. It is directly related to the shelf life of oil and fat-containing foods. [0003] In the actual production process, it often occurs that oils and fats are oxidatively sta...
