Embodiment 1

[0015] Embodiment 1: The production method of peanut protein isolate of this embodiment comprises the following steps in sequence:

[0016] (1). Red coat removal and crushing: Weigh 100 tons of peanut kernels with an oil content of 45%, put them into a cleaning sieve, remove 0.5 tons of impurities, dry them in a dryer, blow them with hot air at 100°C for 10 seconds, and then Quickly blow with cold wind at 20°C for 200 seconds, the peanuts are crushed into 8 petals by a double-pair roller crusher, and 3 tons of red coats are separated by a separation sieve and a separator;

[0017] (2). Low-temperature degreasing: Add 2 tons of peanut oil to the peanuts after removing the red coat, and refine them twice through a refiner so that 95% of them can pass through a 100-mesh sieve. The oil content is reduced to 3.5% (dry basis), and 55 tons of peanut meal with a water content of 2% are obtained;

[0018] (3). Isolate protein: extract the obtained peanut meal with No. 6 extraction sol...

Embodiment 2

[0019] Embodiment 2: The production method of peanut protein isolate of this embodiment comprises the following steps in sequence:

[0020] (1). Red coat removal and crushing: Weigh 100 tons of peanut kernels with an oil content of 43%, screen and remove 0.5 tons of impurities, dry them in a dryer, blow them with hot air at 80°C for 60 seconds, and then quickly dry them at 28°C The cold wind blows for 360 seconds, breaks the peanuts into 4 petals, and screens out 2.5 tons of red clothes;

[0021] (2). Low-temperature degreasing: add 6 tons of peanut oil to the peanuts after removing the red coat, refine them through a colloid mill for 4 times, so that 95% of them can pass through a 180-mesh sieve, and press the oil slurry at 30°C to make the peanut meal oily The amount is reduced to 5% (dry basis), and the obtained moisture content is 59 tons of peanut meal of 2%;

[0022] (3). Isolation of protein: Extract the obtained peanut meal with No. 6 extraction solvent oil for 120 mi...

Embodiment 3

[0023] Embodiment 3: The production method of peanut protein isolate of this embodiment comprises the following steps in sequence:

[0024] (1). Red coat removal and crushing: Weigh 100 tons of peanut kernels with an oil content of 46%, screen and remove 0.35 tons of impurities, dry them in a dryer, blow them with hot air at 110°C for 3 seconds, and then quickly dry them at 10°C The cold wind blows for 120 seconds, breaks the peanuts into 10 petals, and screens out 3.2 tons of red clothes;

[0025] (2). Low-temperature degreasing: Add 4 tons of peanut oil to the peanuts after removing the red coat, and refine them once through a colloid mill, so that 95% of them can pass through a 60-mesh sieve, and press the oil slurry at 70°C to make the peanut meal oily. The amount is reduced to 4% (dry basis), and the obtained moisture content is 55.5 tons of peanut meal of 2%;

[0026] (3). Isolate protein: extract the obtained peanut meal with solvent for 90 minutes, remove the solvent ...

Abstract

A process for preparing peanut protein includes such steps as peeling the peanut, breaking, grinding by 60-180 meshes, low-temp (30-70 deg.C) deoiling, extracting from the dregs in solvent, removing solvent at 40-80 deg.C under 300-650 Pa, extracting, separating and drying. Its advantages are high output rate and purity, high productivity and low cost.

Description

technical field [0001] The invention relates to a method for producing peanut protein isolate from high oil-containing oil species, and belongs to the technical field of edible protein processing methods. Background technique [0002] Oil isolate protein is a kind of oil protein produced after degreasing and further processing of oil seeds. High-oil-containing oils such as peanuts and rapeseeds have high oil content, and low-temperature degreasing is difficult. However, high-temperature degreasing, that is, using high-temperature pressing to reduce oil content first, then extracting and high-temperature desolventization to produce meal, will cause protein denaturation and loss of activity, and protein isolates cannot be extracted. Therefore, only low oil-containing oils such as soybeans can be used to produce protein isolates in current production. Peanut protein is rich in nutrition, rich in various amino acids needed by the human body, easily absorbed by the human body, a...
