Embodiment 1～5、 comparative example 1～4

[0059] Using a deodorizer, the decolorized rapeseed oil (manufactured by Nisshin Oiliyo Group Co., Ltd.) was deodorized under the conditions described in Table 1 to obtain the purified rapeseed oil of each Example and Comparative Example.

[0060] The deodorizing device used is any one of the following devices. The girdler-type deodorizer 1 is a continuous deodorizer, and has a structure in which all the trays are connected together by piping provided between the trays, and fats and oils are continuously supplied into the apparatus. The girdler-type deodorizer 2 is a semi-continuous deodorizer, and has a structure in which valves are provided on each tray, so that fats and oils between the trays are less likely to mix.

[0061] Device 1: girdler type deodorization device 1

[0062] Device 2: girdler type deodorization device 2

[0063] Device 3: batch type deodorization device

[0082] [Example 6 and Example 7, Comparative Example 5 and Comparative Example 6]

[0083] The decolorized rapeseed oil (manufactured by Nisshin Oillio Group Co., Ltd.) was deodorized under the following conditions using a deodorizer to obtain purified rapeseed oils in Examples and Comparative Examples. In addition, "apparatus 1" and "apparatus 2" mentioned below mean the same apparatuses as "apparatus 1" and "apparatus 2" used in Examples 1-5 and Comparative Examples 1-4, respectively.

[0084] Example 6 and Example 7: "Apparatus 1" was used in Example 6, "Apparatus 2" was used in Example 7, at 220°C, vacuum degree 400Pa (3torr), 60 minutes, water vapor blowing amount 3.4 The decolorized rapeseed oil was brought into contact with water vapor under the condition of mass %. This step corresponds to the "contacting step" in the present invention.

Embodiment 8、 comparative example 7 and comparative example 8

[0093] Using a deodorizer, the decolorized rapeseed oil (manufactured by Nisshin Oiliyo Group Co., Ltd.) was deodorized under the conditions described in Table 3 to obtain the refined rapeseed oil of each Example and Comparative Example. Next, 800 g of each refined rapeseed oil was poured into a fryer, and each refined rapeseed oil was subjected to a frying process by raising the temperature to 180°C. When the temperature reached 180° C., a portion of the purified rapeseed oil was collected and the following evaluations were performed.

Abstract

The invention provides a production method of refined colza oil, a refined colza oil produced by using the method, and an acid emulsion food containing the above mentioned colza oil, and a method of reducing the aldehydes in the refined colza oil. The refined colza oil can be used to inhibit the reduction of the alfa- tocopherol, and can be used to reduce the trans-fatty acids, and the flavor is good. The production method provided by the invention comprises a deodorization process, and the deodorization process is characterized in that the deodorization process comprises a contact process, namely the colza oil is contacted with the vapor for 53-100min under the temperature condition in a range from 205 to 225 DEG C and the vacuum degree in a range from 300 to 800 Pa. The content of the vapor can be 1.0-5.0 wt% by comparing with the colza oil. The above mentioned deodorization process can be carried out by using the tray-type deodorization device.

Description

technical field [0001] The present invention relates to a method for producing refined rapeseed oil, rapeseed oil obtained by the production method, an acidic emulsified food containing the refined rapeseed oil, and a method for reducing aldehydes in rapeseed oil. Background technique [0002] In recent years, with the improvement of consumers' health awareness, people pay more attention to nutritional functional foods labeled with specific nutritional functions. [0003] When the food is sold as a nutritional functional food, it must meet the specifications and standards of the nutritional functional food. As an example of the specification standard, when the nutrient component is α-tocopherol (vitamin E), the lower limit of the nutrient component contained in the daily appropriate intake is 2.4 mg. According to the estimation of the National Nutrition Survey (1995), the average daily intake of fats and oils of Japanese people is 14g. Therefore, if this intake is regarded...
