preparation example Construction

[0114] The preparation method provided by the present invention can be used to prepare peanut oil or products containing peanut oil.

[0115] The peanut oil product of the present invention retains the good flavor of peanut oil, and one or more of the above-mentioned properties is superior to ordinary peanut oil. It can be applied to many aspects like ordinary peanut oil, including: food preparation or As an additive in food preparation. For example, it is used in the production of stir-frying, oil and fat, and the preparation of foods such as bread, cakes, biscuits, toffee, popcorn, non-dairy creamer, candy, puffed food, etc. Since the peanut oil of the invention has low saturated fatty acid content, the food prepared by using the peanut oil is more beneficial to health.

[0116] The main advantages of the processing method and product of the present invention

[0117] (1) The method of the present invention has simple process, short operation time, high yield, no introduction of ...

Embodiment 1

[0172] Example 1. Preparation of peanut oil product 1

[0173] The raw peanut oil is heated to 15°C, and then passed through a static mixer (the front of the mixer is equipped with a nitrogen inlet with a one-way valve), and a small amount of nitrogen (pressure controlled at 0.3bar) is mixed and homogenized (static mixer). Transported to the crystallization tank, according to the pre-set program, the oil temperature is slowly reduced from 35°C to -2°C, the cooling rate is controlled to 2°C / hour, and the stirring speed is controlled to 15RPM. Then, the crystal is cultivated for 1.5 hours, and the stirring speed is 5RPM during crystal growing. After crystal growing, it is transported to a membrane filter press with accompanying cooling by a screw pump (the accompanying cooling temperature is controlled at 2°C). The filter cloth material is air permeability 100l / dm 2 / min antistatic polyester cloth, filter pressure 1~3bar, get clear liquid oil.

Embodiment 2

[0174] Example 2. Preparation of peanut oil product 2

[0175] Heat the ordinary peanut oil to 37°C, then pass a small amount of nitrogen (pressure controlled at 0.3bar) through a static mixer, mix and homogenize, and then transfer it to the crystallization tank. According to the preset program, the temperature drops from 37°C To -3°C, control the cooling rate to 2.5°C / hour, and control the stirring speed to 14RPM. Then, the crystal is grown for 1 hour, and the stirring speed is 8RPM during the growth of the crystal. After the growth of the crystal, it is transported to the membrane filter press with accompanying cooling by a screw pump for filtration (the temperature of the accompanying cooling is controlled at 0-1℃). The filter cloth material is Antistatic polyester cloth with an air permeability of 120l / dm2 / min and a filtration pressure of 1 to 3 bar to obtain a clear liquid oil.

Abstract

The invention relates to a low saturation peanut oil product maintaining the flavor of peanut oil. The invention reveals a method of effectively reducing the contents of saturated fatty acid and metal ions in peanut oil and/or improving low temperature resistance of peanut oil on the basis of maintaining the flavor of peanut oil. The method comprises the following steps: temperature control; homogenization; cooling crystallization; filtering; etc. The method is feasible and has low cost and a substantial optimization effect on the performance of an oil product.

Description

Technical field [0001] The invention belongs to the field of food science and food processing; more specifically, the invention relates to a low-saturated peanut oil product that maintains the aroma of peanut oil. Background technique [0002] Peanut oil is light yellow, transparent, clear in color, fragrant, and delicious. It is a kind of edible oil that Chinese residents like. The fatty acid contained in peanut oil is characterized by containing 20% ​​of long-chain saturated fatty acids (palmitic acid (C16:0), stearic acid (C18:0), arachidic acid (C20:0), behenic acid (C22:0) Compared with wood tar oleic acid (C24:0)), the content of long-chain saturated fatty acids is relatively high compared with other edible oils consumed by residents in the market, such as soybean oil, rape oil, corn oil, sunflower oil, tea seed oil and other oils. According to reported experimental studies, the activity of 3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase in the liver increases af...
