Embodiment 1

[0030] Follow the following steps successively to decolorize the peony seed oil after deacidification:

[0031] (1) Weigh 500g of deacidified peony seed oil and preheat at 90°C for 30min;

[0032] (2) Put the standby activated clay and attapulgite in a drying oven at 105°C, after activating for 2.0 hours, take them out and place them in a desiccator for later use;

[0033] (3) Add 4% composite decolorizing agent to the preheated peony seed oil, the addition ratio of activated clay and attapulgite in the composite decolorizer is 1:1, that is, add 10g activated clay and 10g attapulgite; control the decolorization temperature The temperature is 85°C, the decolorization vacuum degree is between -0.095~-0.090MPa, the ultrasonic auxiliary power is 40kHz, the mechanical stirring rate is 120r / min, and the decolorization time is 25min;

[0034] (4) After the decolorization treatment of peony seed oil is completed, it is cooled to about 60° C. under a vacuum degree of -0.095 to -0.090 ...

Embodiment 2

[0037] Adjust the addition ratio of activated clay and attapulgite in Example 1 to 2:3, that is, add 8g activated clay and 12g attapulgite, and the other operating steps and parameters are the same as in Example 1, and the peony seed oil is decolorized operation, the decolorized peony seed oil is prepared.

[0038] It was found that the decolorized peony seed oil was light yellow or golden yellow, and the oil was clear and transparent. It was further detected by the Lovibond colorimeter that the color of the oil was significantly improved, indicating that the decolorization effect of the process was good. By analyzing the content of trace active ingredients (including vitamin E and phytosterols) and neutral oil content in peony seed oil before and after decolorization, and comparing it with conventional activated clay decolorization of peony seed oil, the results show that the above decolorization method is also effective Reduce the loss of trace active ingredient content and ...

Embodiment 3

[0040] The dosage of the composite decolorizing agent in Example 1 is adjusted to 3%, the addition ratio of activated clay and attapulgite is adjusted to 2:1, that is, 10g activated clay and 5g attapulgite are added, the decolorization time is adjusted to 30min, and other operations The steps and parameters are the same as in Example 1, and the peony seed oil is decolorized to prepare the decolorized peony seed oil.

[0041] It was found that the decolorized peony seed oil was light yellow or golden yellow, and the oil was clear and transparent. It was further detected by the Lovibond colorimeter that the color of the oil was significantly improved, indicating that the decolorization effect of the process was good. By analyzing the content of trace active ingredients (including vitamin E and phytosterols) and neutral oil content in peony seed oil before and after decolorization, and comparing it with conventional activated clay decolorization of peony seed oil, the results show...

Abstract

The invention discloses a method for decoloring peony seed oil. The method is characterized by sequentially comprising the following steps: (1) preheating the deacidified, washed and dried peony seed oil; (2) heating and activating activated clay for decoloration and attapulgite in a drying oven; (3) adding a compound decolorizing agent into the preheated oil, controlling the temperature and decolorizing vacuum degree in a decolorizing environment, and performing mechanical stirring under the ultrasonic-assisted action to complete the decolorizing process operation of the peony seed oil; and (4) after the decolorization treatment is finished, performing cooling under a vacuum condition, and then carrying out suction filtration to obtain the decolorized peony seed oil. The peony seed oil is grease subjected to deacidification, water washing and drying; and the decolorizing agent is a decolorizing agent compounded by activated clay and attapulgite. According to the novel peony seed oil decolorizing process, the decolorizing agent consumption and the decolorizing processing cost are reduced, the decolorizing effect is good, the decolorizing time is short, the operation is convenient, the quality of the decolorized peony seed oil is effectively improved, and large-scale production and application in peony seed oil processing enterprises are facilitated.

Description

technical field [0001] The invention relates to a method for decolorizing peony seed oil, which belongs to the technical field of edible oil processing. Background technique [0002] Peony seed oil is the oil extracted from peony seeds for oil, and the oil yield of peony seeds for oil is about 29% to 34%. Studies have found that peony seed oil is rich in more than 100 nutritional and physiologically active substances such as linolenic acid, linoleic acid, docosahexaenoic acid, paeonol, paeonol saponins, peony polysaccharides, fucosterol, squalene, etc. The main effects are reflected in anti-oxidation, anti-tumor, anti-bacterial and anti-inflammatory, lowering blood fat, lowering blood sugar, protecting liver damage and so on. Toxicological studies also show that peony seed oil has no acute toxicity and subacute toxicity, and is a kind of oil with high edible safety. In 2011, the Ministry of Health (now the National Health Commission) listed peony seed oil as a new resource...
