example

[0048] Hereinafter, the present invention will be specifically explained based on examples, but the present invention is not limited to these examples.

[0049] [Preparation of polyglycerin fatty acid ester]

[0050] Glycerin and sodium hydroxide were mixed, heated to 90°C, and dried under reduced pressure. Next, it is heated to 200 to 270°C, stirred and reacted, and then filtered to obtain polyglycerol. The degree of polymerization of polyglycerol can be measured by the hydroxyl value and calculated from the theoretical hydroxyl value of polyglycerol. This polyglycerol and the following fatty acids were mixed, sodium hydroxide was added as a catalyst, and they were reacted at 200° C. under nitrogen gas flow to obtain samples 1 to 6 whose specifications were changed as shown in Table 1. In addition, the amount of fatty acids in Table 1 is defined as the mass percentage in the constituent fatty acids.

Abstract

The invention provides an oil-fat composition for heat cooking capable of substantially reducing an increase in acid value thereof in heat cooking over a long period of time, a manufacturing method thereof, and an acid-value increase inhibitor for the oil-fat composition for heat cooking. The oil-fat composition is characterized in that the oil-fat composition contains, by mass, 0.01-2% of polyglycerol fatty acid ester, the average degree of polymerization of the polyglycerol that constitutes the polyglycerol fatty acid ester is 12-40, and the hydroxyl value is below 180.

Description

Technical field [0001] The present invention relates to an oil and fat composition for heating cooking, a method for producing the same, and an acid value increase inhibitor for an oil and fat composition for heating cooking Background technique [0002] In recent years, concerns about food quality have increased, and the edible fats and oils actually used in processed foods such as fried foods are no exception. Edible oils and fats are generally degraded by heat and light. At this time, hydrolytic degradation occurs due to the presence of moisture, or oxidative degradation due to the presence of oxygen, and the flavor or color tone is also degraded. Hydrolysis mainly affects the value of acid value, and oxidative degradation mainly affects the value of peroxide value. Therefore, acid value or peroxide value is used as a deterioration indicator of edible fats and oils. In particular, oil-cooked products such as fried, tempura, and tangyang contain a lot of water. Therefore, whe...
