[Problem] To obtain, from rice bran, an excellent rice oil at a high yield and also obtain an excellent defatted rice bran. [Solution] A method for obtaining an excellent rice oil and an excellent defatted rice bran, said method comprising: a first treatment step for contacting fresh rice bran immediately after obtained in a rice milling step with superheated steam to inactivate enzymes therein; a second treatment step for extracting rice oil from the rice bran obtained in the first treatment step; and a third treatment step for separating and obtaining defatted rice bran. It is preferred that, in the first treatment step, the rice bran is contacted with superheated steam at 250-650oC for 0.5-60 sec. The rice oil thus extracted has a low acid value. The defatted rice bran thus obtained is free from germs and has no offensive smell and, therefore, is good to eat as a meal.

Method for obtaining rice oil and defatted rice bran from fresh rice bran

PROBLEM TO BE SOLVED: To provide a means capable of efficiently including a useful component such as polyphenol in edible oil. SOLUTION: An edible oil producing method comprises, when squeezing edible oil from an oil-containing raw material, squeezing oil after making lipase act on the oil-containing raw material so that a diacylglycerol content in oil and fat obtained after squeezing oil becomes ≥4 mass%.

Edible oil producing method

PROBLEM TO BE SOLVED: To provide such a process in the recovery of oil and fats from rice bran as is made both to elevate a yield of rice bran oil and to increase a content of physiologically active sterol and orizanol. SOLUTION: This yield-increasing process for physiologically active rice bran oil comprises pretreating rice bran with an enzyme in the extraction of oil from the rice bran, which results in a yield of oil and fats of 20 wt.% or more on the basis of the rice bran and also a content of sterol and orizanol of 1.8 wt.% or more. The enzyme is desirably an enzyme mixture contg. amylase, cellulase, and protease.
