Problems solved by technology

Differences in texture between chocolate flavored powder and chocolate prevent detection by the same method
The traditional chocolate fineness detection method uses liquid paraffin as a solvent. When using this method to detect the fineness of chocolate flavor powder, the data fluctuates greatly, and an accurate fineness value cannot be obtained
If the chocolate flavor powder is liquefied and made into chocolate for fineness detection, it will cause secondary processing, and it will take time for liquefaction, so it cannot be detected in time and accurately

Embodiment 1

[0020] 1 Instruments and Utensils

[0021] 1.1 digital display test micrometer

[0022] Measuring range: 0mm-25mm.

[0023] Accuracy: 0.001mm.

[0024] 1.2 stainless steel spoon

[0025] 1.3 beaker

[0026] 50mL.

[0027] 2 reagents

[0028] 50% phospholipid + 50% sunflower oil solution

[0029] 3 Measurement steps

[0030] 3.1 Preparation of samples

[0031] Take 5g of a representative sample of chocolate flavor powder, put it into a 50ml beaker, add 15g of reagent heated to about 50°C, and mix until there are no aggregated lumps. The prepared sample should be measured within 5min.

[0032] 3.2 micrometer zero adjustment

[0033] Rotate the micrometer sleeve so that the distance between the two measuring planes is about 10mm, carefully wipe the measuring plane clean with soft paper or soft cloth.

[0034] Turn on the micrometer switch to select the measurement range.

[0035] Turn the ratchet slowly to bring the two measuring planes closer together. When the two ...

Embodiment 2-3

[0061] Embodiment 2-3: similar to embodiment 1, the detection reagent is prepared according to the following ratio:

[0062] Example 2 Example 3 Sunflower seed oil Sunflower seed oil Phospholipids 1∶2 2∶1

Embodiment 4-10

[0063] Embodiment 4-10: Similar to embodiment 1, the detection reagent is prepared according to the following ratio:

[0064]

[0065]

[0066] Similar to Example 1, the detection reagent prepared above and the detection reagent of Comparative Example 1-2 were used to detect the fineness of chocolate flavor powder at least 3 times, and the results showed that the reagent of the present invention meets the detection requirements, especially the detection of sunflower oil. The data fluctuation is small, and the measured fineness value is stable and accurate.

Abstract

The invention relates to a method for detecting fineness of chocolate flavor powder and provides a method for detecting fineness of chocolate flavor powder. The method comprises steps that a chocolateflavor powder sample is contacted with detection reagent, fineness of the sample is determined, and the detection reagent comprises emulsifier and liquid ester containing unsaturated fatty acid. Theinvention further provides the use of the detection reagent comprising emulsifier and liquid ester containing unsaturated fatty acids for detecting fineness of chocolate flavor powder. The method canaccurately detect fineness of the chocolate flavor powder and reduce data fluctuation.

Description

technical field [0001] The invention relates to the field of chocolate and its products, in particular to a method for detecting the fineness of chocolate flavor powder. Background technique [0002] Since chocolate is made by mixing chocolate flavor powder and oil, the fineness index of chocolate flavor powder determines the fineness of chocolate and plays a role in the fineness of chocolate taste. But there is only the fineness detection method of chocolate in the chocolate industry at present, and there is no fineness detection method of chocolate flavor powder. Chocolate flavored powder and chocolate have different tissue states, so the same method cannot be used for detection. The traditional chocolate fineness detection method uses liquid paraffin as a solvent. When using this method to detect the fineness of chocolate flavor powder, the data fluctuates greatly, and an accurate fineness value cannot be obtained. If the chocolate flavor powder is liquefied and made in...
