Embodiment 1

[0038] The concrete preparation operation steps of a kind of solid tea oil rich in polyphenols are as follows:

[0039] Step 1 Preparation of particle dispersed phase

[0040] First, measure 100 ml of tea oil and place it in a beaker, heat it to 95 °C, and add 0.5 g of tea polyphenol palmitate and 1 g of glyceryl monopalmitate while stirring the tea oil at a speed of 1200 r / min. Until tea polyphenol palmitate and glyceryl monopalmitate dissolve completely, obtain the tea oil solution containing tea polyphenol palmitate and glyceryl monopalmitate; Under the condition of power of 500W and temperature of 50°C, ultrasonic treatment was performed for 25 min; then, the ultrasonically treated camellia oil solution was placed in liquid nitrogen and quickly frozen for 8 min to obtain completely frozen camellia oil; finally, the frozen camellia oil was Slowly melt into a liquid state at 25°C to obtain 94 ml particle dispersion phase containing tea polyphenol palmitate and glycerol mono...

Embodiment 2

[0049] The concrete preparation operation steps of a kind of solid tea oil rich in polyphenols are as follows:

[0050] Step 1 Preparation of particle dispersed phase

[0051] First, measure 2000 ml of tea oil and place it in a stirring tank, heat it to 98 ° C, and add 12 g of tea polyphenol palmitate and 26 g of monopalmitin while stirring the tea oil at a speed of 1000 r / min, Until tea polyphenol palmitate and glyceryl monopalmitate dissolve completely, obtain the tea oil solution containing tea polyphenol palmitate and glyceryl monopalmitate; Under the conditions of 400W power and 53°C, ultrasonic treatment was performed for 22 minutes; then, the tea oil solution after ultrasonic treatment was quickly frozen in liquid nitrogen for 10 minutes to obtain completely frozen camellia oil; finally, the frozen camellia oil was placed in Slowly melted into a liquid state at 22°C to obtain a particle dispersion phase of 1875 ml of tea polyphenol palmitate and glycerol monopalmitate....

Embodiment 3

[0060] The concrete preparation operation steps of a kind of solid tea oil rich in polyphenols are as follows:

[0061] Step 1 Preparation of particle dispersed phase

[0062] First, measure 6000 ml of tea oil and place it in a stirring tank, heat it to 100°C, and while stirring the tea oil at a speed of 800 r / min, add 30 g of tea polyphenol palmitate and 120 g of glyceryl monopalmitate until Tea polyphenol palmitate and glyceryl monopalmitate are completely dissolved to obtain a tea oil solution containing tea polyphenol palmitate and glyceryl monopalmitate; Under the conditions of 300W and 55°C, ultrasonic treatment was performed for 20 min; then, the ultrasonically treated camellia oil solution was quickly frozen in liquid nitrogen for 12 min to obtain completely frozen camellia oil; finally, the frozen camellia oil was placed in Slowly melt into a liquid state at 20°C to obtain a particle dispersion phase of 5580 ml of tea polyphenol palmitate and glycerol monopalmitate; ...

Abstract

The invention relates to solid sate camellia seed oil rich in polyphenols and a preparation method thereof. The solid state camellia seed oil rich in polyphenols is a milky-white block solid, with oilcontent greater than 90%, hardness of 160-350 g, peroxide value not higher than 3.50 mmol/kg and DPPH free radical scavenging rate not less than 92%. The solid state camellia seed oil is prepared byusing the tea polyphenol palmitate and the monopalmitin as particle emulsifiers, the pectin as a stabilizing agent and a gelling agent and the camellia seed oil as an oil phase. The preparation methodis simple and convenient in process, easy to implement and capable of widening application fields of the tea polyphenol palmitate and the pectin and improving the safety and nutritional value of solid state oils and fats. The solid state camellia seed oil can be directly added in the production of cakes, ice cream and other products, and can bring a unique flavor and health care effects while reducing trans fatty acid contents in the above-mentioned products, thereby improving product quality. The solid state camellia seed oil is capable of maintaining a good solid state at room temperature,convenient for storage and transportation and being directly used after stirring and crushing.

Description

technical field [0001] The invention belongs to the field of edible oil processing, and in particular relates to a method for preparing solid camellia oil rich in polyphenols. Background technique [0002] Fat refers to fats that are in a solid state at room temperature. It has a decisive impact on the mixing, molding, fermentation, sensory quality and shelf life of the final product in the food production process. Generally, what we call solid oil generally includes two types: one is natural animal fat or tropical vegetable fat containing a large amount of saturated fatty acids, such as palm oil, cocoa butter, coconut oil, etc.; the other is through the separation of animal and vegetable oils. A solid or semi-solid oil product with certain plasticity obtained by extraction, hydrogenation, transesterification or mixing techniques, such as shortening, margarine, low-temperature special oil, etc. sold on the market. Natural animal and vegetable fats contain a large amount of ...
