Abstract
The invention provides an identification method for hot pot tallow quality, and relates to an identification method for hot pot raw materials. The method is characterized in that: the method comprises an identification method of the palm oil-containing tallow, an identification method of the tallow added with hydrogen peroxide, and an identification method of the tallow added with paraffin. The identification method of the present invention is simple, and is easy to perform. With the method of the present invention, the tallow added with the paraffin, the tallow added with the hydrogen peroxide, the tallow added with the industrial palm oil, and other counterfeit products can be effectively identified, and the interests of the consumers can be protected.
Description
Technical field
The present invention relates to chafing dish raw material discrimination method, be specifically related to a kind of discrimination method of chafing dish butter quality.
Background technology
As everyone knows, the primary raw material of chafing dish is butter, because chafing dish oil product board is various at present, and disorderly competition, in order to reduce cost, its quality makes people worried.In fact, as the primary raw material butter of chafing dish, especially be best with the yellow grease with oil; And pure ox mainly produces the middle and lower reaches in the Huanghe valley, and is the best with Shandong, Yu Bei and the Wan Bei in downstream, the Yellow River, and it has the peat-reek of yellow grease; And the Yangtze river basin and shy burning is arranged with the buffalo oil in the south of the River, the sheep oil in area, grassland has smell of mutton, and the grassland ox is because thinner; Its butter fragrance is lighter, and the grass flavor is arranged.
Operator and user owing to be the professional scarcely, do not differentiate the ability and the knowledge of quality good or not, and it are like this equally with the enterprises and individuals of oil to sell and consume chafing dish when any product of consumption.In recent years, add problems such as food wax, oxydol, industrial palm oil, butter essence for the chafing dish butter, constantly be reported in media, and milk powder case at no distant date etc., its problem is startling.Some illegal producers, for enhancing the reputation, the deception consumer, do not stint with pay a high price for non-qualification and inauthoritativeness department titled with " national consumer's trustworthy quality product " and some places and the civil society various titles of authorizing, misguide the consumer.
Summary of the invention
It is a kind of simple and practical in order to differentiate chafing dish butter method for quality that technical matters to be solved by this invention is to provide
Technical matters to be solved by this invention adopts following technical scheme to realize,
A kind of discrimination method of chafing dish butter quality is characterized in that:
It is 1, following to the discrimination method that contains the palm oil butter,
1. get the part oil sample, in pot, be warmed to more than 100 ℃, but do not reach smoke point (Mao Qingyan), can smell the fragrance that contains milk powder, after heating several minutes, stop to heat, let its natural cooling;
2. with step 1. in cooled grease heat for the second time, milk fragrance is completely without, no butter fragrance, can be judged to be to contain industrial palmitic butter;
3. get the sample that pure butter of part and same section need be differentiated, be placed on respectively in two different beakers, heat down,, promptly contain industrial palm oil in the decidable sample butter if the beaker solution time of sample is longer than the beaker time of containing pure butter in identical temperature; Otherwise under identical ambient temperature condition (ambient temperature is lower than 30 ℃), the beaker setting time of containing the sample butter significantly is shorter than the time of another beaker, promptly contains industrial palm oil in the decidable sample butter;
It is 2, following to the discrimination method that adds the oxydol butter,
1. get sample segment, hear the section of its grease, no butter are fragrant, can be judged to be to contain to add the oxydol butter;
2. get sample segment, be placed in the transparent container after it is dissolved, its liquid is as clear as crystal, but the bubble output is arranged, and can be judged to be to contain to add the oxydol butter;
3. get sample segment, when being warmed to them more than 100 ℃ the peculiar smell output is arranged, can be judged to be to contain and add the oxydol butter;
It is 3, following to the discrimination method that adds the paraffin wax butter,
1. get sample segment, hear its section, fragrant or be placed in the mouth and can not dissolve like no butter, like chewing wax promptly can judge contain paraffin wax;
2. get sample segment and be placed in beaker or the iron pan, be heated to 43 ℃～48 ℃, as do not have off-bottom, can see that at transparent liquid in container cotton-shaped or irregular solids is arranged, promptly contain the paraffin wax butter;
3. get sample segment and be placed in beaker or the iron pan, be heated to more than 160 ℃, reach smoke point (Mao Qingyan), as smell the smell that has candle to extinguish, or the smell of analysis of phenols is arranged, the paraffin wax butter are promptly arranged.
The invention has the beneficial effects as follows: discrimination method of the present invention is simple, is convenient to implement, and can effectively identify butter and add food wax, oxydol, industrial palm wet goods fake products, protection consumer's rights and interests.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and understand, below in conjunction with instantiation, further set forth the present invention.
