れていた。(Conventional technology) Cotton seeds have abundant high quality proteins, lipids,
It is also rich in vitamins, minerals, and other nutrients, and is excellent in nutrition. However, because there is a ground (gland) that secretes gossypol toxin, cottonseed that is conventionally supplied for edible use has a high temperature.
It had to be roasted at 121.1 ° C or more for 5 minutes or more to decompose gossypol. As the means, heat transfer heating by an electric drying device or the like is usually used, but when roasting at a high temperature for a long time as described above, cottonseed exhibits a brown or dark brown burnt color, and protein, Since lipids and other substances are denatured and the flavor is cooked and has a bean smell, it is not nutritious but has no application to a wide range of foods such as soybeans. It had been.

どの欠点を有している。Varieties were also improved to reduce gossypol content in cottonseed.However, gossypol still contained 50 to 500 ppm, and as much as possible, decomposing gossypol as much as possible and various attempts have been made to reduce the content. However, as described above, it has been considered that the best method is to decompose gossypol by roasting at a temperature of 121.1 ° C. or more for 5 minutes or more for a long time as described above. However, when heated at such a high temperature for a long time, the cottonseed is burnt or deteriorates. In addition, there is a disadvantage that it takes a long time to raise the product temperature, and energy costs and equipment costs are high.

を発明した。(Means for Solving the Problems) The present inventor tried various methods to decompose gossypol without burning or deteriorating cottonseed.
A method for easily and efficiently decomposing gossypol by far-infrared heating and roasting due to good internal heat permeability of far-infrared rays was invented.

る。180℃以上では綿実が焦げるので適当でない。When heating and roasting with far-infrared light, for example, a far-infrared heating and roasting machine of 4 kw x 6 far-infrared heater is used,
If the temperature is high in the temperature range of 0 ° C to 180 ° C (for example,
180 ° C.) is a short time (for example, 3 minutes), and a low temperature (for example, 70 ° C.) is for a long time (for example, 10 minutes), so that gossypol in cottonseed can be decomposed. Above 180 ° C, cotton seeds burn and are not suitable.
次に本発明の効果を実験例によって説明する。 Next, the effects of the present invention will be described with reference to experimental examples.
実験例１ 遠赤外線加熱焙焼による場合と伝熱加熱焙焼による場
合を比較するために、遠赤外線加熱器と送風定温加熱器
を用いて、綿実を加熱し品温の上昇速度を比較した。Experimental Example 1 In order to compare the case of far-infrared heating and roasting with the case of heat transfer heating and roasting, a cotton seed was heated using a far-infrared heater and a blower constant-temperature heater, and the rate of increase in product temperature was compared. .
綿実約100gずつ紙上に均一に並べ、内温度80℃に
平衡化させた。両加熱器に入れ、温度センサーを用いて
綿実の品温が設定温度に達する時間を測定した。その結
果、遠赤外線加熱の場合、約５培の速度で設定温度に達
した。Approximately 100 g of cotton seeds were uniformly arranged on paper and equilibrated to an internal temperature of 80 ° C. The cotton seeds were placed in both heaters, and the time required for the temperature of the cottonseed to reach the set temperature was measured using a temperature sensor. As a result, in the case of far-infrared heating, the temperature reached the set temperature at a speed of about 5 times.
実験例２ 実験例１で品温80℃で10分間加熱した綿実の熱凝固性
蛋白質の変化を調べるために、加熱した綿実20gの常温
での脱イオン水の吸水率を測定した。EXPERIMENTAL EXAMPLE 2 In order to examine the change in the heat-coagulable protein of cotton seeds heated at a product temperature of 80 ° C. for 10 minutes in Experimental Example 1, the absorption rate of deionized water of 20 g of heated cottonseed at room temperature was measured.
実験結果は次の通りである。 The experimental results are as follows.
以上のように遠赤外線加熱した綿実は未処理の綿実と
ほぼ同様の吸水率を示した。しかしながら送風定温加熱
した綿実は低い吸水率を示した。これは、実験例１より
品温が一定温度まで上昇するために長時間を要するため
に必要以上の熱がかかり、熱凝固性蛋白質が熱変性した
ものと考えられる。 As described above, the cotton seeds heated by far-infrared rays showed almost the same water absorption as the untreated cotton seeds. However, the cottonseed heated at a constant temperature showed low water absorption. This is considered to be due to the fact that a longer time is required for the product temperature to rise to a certain temperature than in Experimental Example 1 and therefore more heat was applied than necessary, and the heat-coagulable protein was thermally denatured.
実施例１ 綿実約100gずつ紙上に均一に並べ、内温度を70℃
及び80℃にて10分間遠赤外線加熱焙焼した後ゴシポール
の含量を測定した。Example 1 About 100 g of cotton seeds are uniformly arranged on paper at an inner temperature of 70 ° C.
After heating and roasting at 80 ° C. for 10 minutes with far infrared rays, the content of gossypol was measured.

Gossypol in cottonseed was extracted with a mixed solution of glacial acetic acid, subjected to high performance liquid chromatography, and detected. Detection limit is 10pp
m. As described above, gossypol was not detected at all by the far-infrared heating and roasting, and heat denaturation of the protein was hardly recognized.
