Embodiment 1

[0031] This embodiment provides a method for preparing a cream-flavored peanut oil with pulsed electric field pretreatment and 10 times of pulse treatment, comprising the following steps:

[0032] (1) Raw material pretreatment: select 50 g of freshly produced peeled peanut kernels each time, immerse it in deionized water, and adjust its moisture content to 54-56% for later use.

[0033] (2) Peanuts processed by PEF equipment: Put the prepared peeled peanuts into the processing chamber, add deionized water to fix the distance between the plates to 30mm, press the electrode plates, and exhaust the air bubbles to fill the entire processing chamber with deionized water. Under the condition of intensity of 1.22-1.24kV / cm, frequency of 1Hz, pulse width of 250μs, and pulse treatment times of 10, peanut kernels were treated with PEF.

[0034] (3) Dried peanut kernels: remove the peanut kernels after PEF treatment, put them in a petri dish immediately, put them into an oven at a temper...

Embodiment 2

[0038] This embodiment provides a method for preparing a cream-flavored peanut oil with a pulse electric field pretreatment and pulse treatment times of 20 times, comprising the following steps:

[0039] (1) Raw material pretreatment: select 50 g of freshly produced peeled peanut kernels each time, immerse it in deionized water, and adjust its moisture content to 54-56% for later use.

[0040] (2) Peanuts processed by PEF equipment: Put the prepared peeled peanuts into the processing chamber, add deionized water to fix the distance between the plates to 30mm, press the electrode plates, and exhaust the air bubbles to fill the entire processing chamber with deionized water. Under the condition of intensity of 1.22-1.24kV / cm, frequency of 1Hz, pulse width of 250μs, and pulse treatment times of 20 times, peanut kernels were treated with PEF.

[0041] (3) Dried peanut kernels: remove the peanut kernels after PEF treatment, put them in a petri dish immediately, put them into an ove...

Embodiment 3

[0045]This embodiment provides a pulse electric field pretreatment, a method for preparing cream flavor peanut oil with 40 pulse treatments, comprising the following steps:

[0046] (1) Raw material pretreatment: select 50 g of freshly produced peeled peanut kernels each time, immerse it in deionized water, and adjust its moisture content to 54-56% for later use.

[0047] (2) Peanuts processed by PEF equipment: Put the prepared peeled peanuts into the processing chamber, add deionized water to fix the distance between the plates to 30mm, press the electrode plates, and exhaust the air bubbles to fill the entire processing chamber with deionized water. Under the conditions of intensity 1.22-1.24kV / cm, frequency 1Hz, pulse width 250μs, and pulse treatment times 40 times, peanut kernels were treated with PEF.

[0048] (3) Dried peanut kernels: remove the peanut kernels after PEF treatment, put them in a petri dish immediately, put them into an oven at a temperature of 55-60°C to ...

Abstract

The invention discloses a butter-flavored peanut oil and a preparation method thereof, comprising the following steps: (1) pre-adjusting the moisture content of the peanut kernels: selecting peeled peanut raw materials, soaking them in deionized water, and taking them out for use after reaching the pre-adjusted moisture content; (2) Pulse electric field equipment processing peanut kernels: using pulse electric field extraction equipment, put the peeled peanuts with pre-adjusted moisture into the treatment chamber, add deionized water, fix the distance between the electrode plates, and remove air bubbles to process peanut kernels; (3) Dried peanuts Kernel: Dry peanut kernels in an oven to the required moisture content; (4) Low-temperature pressing: Put peanut kernels into a preheated oil press and press at low temperature to obtain peanut oil; (5) Centrifugal clarification: Centrifuge cold-pressed peanut oil at low temperature to obtain Clear peanut oil with a creamy aroma. The invention pretreats the peanut kernels by the pulse electric field, has a simple preparation process, well retains the nutrients in the peanut oil, and is easy to control the aroma of the cream, and is suitable for producing milk-flavored peanut oil.

Description

technical field [0001] The invention belongs to the field of edible oil processing, and in particular relates to a butter-flavored peanut oil and a preparation method thereof. Background technique [0002] Peanut is one of the four major oil crops in the world, and it is also the largest oil crop and the most important economic crop in China. Peanuts are rich in nutrients, and the main component is fat, with a content of about 50-60%, of which 80% are unsaturated fatty acids, which have a high-quality oil-to-substance ratio; in peanut kernels, peanut protein with a content of about 20% is recognized as having High-quality plant protein with a high amino acid score; in addition, the functional active substances contained in it, such as phenols, vitamins, and phytosterols, enable peanuts to have physiological functions such as enhancing memory, softening blood vessels, and reducing blood lipid metabolism. [0003] Peanut oil is clear in color, delicious in taste and easy to a...
