preparation example Construction

[0040] see Figure 1-5 , the present invention provides a kind of technical scheme: the preparation method of lycopene Pickering nanoemulsion and the preliminary application in food:

[0041] 1. Dissolve OSA-glutinous rice starch modified by OSA (octenyl succinic anhydride) in water, stir well to form a water phase, then dissolve lycopene powder in the oil phase, and mix the water phase with the oil tank;

[0042] 2. The mixed phase is stirred by a high-speed disperser for 5 minutes, and the mixed colostrum is homogenized by a high-pressure homogenizer after passing through a 200-mesh sieve to form a lycopene Pickering nanoemulsion;

[0043] 3. Lycopene Pickering emulsion is spray-dried to make Lycopene Pickering emulsion powder;

[0044] 4. Fully soak 10g of gelatin, add 400ml of water, heat to 80°C until the gelatin is completely dissolved, take 600g of white sugar and 200g of whole milk powder, add an appropriate amount of water, boil until completely melted until it becom...

Embodiment 1

[0053] Prepare lycopene Pickering emulsion by adopting the above scheme, and measure the particle size and dispersion coefficient of the emulsion by using the nanometer particle size and Zeta potential analyzer. All samples are diluted 3000 times with deionized water before testing, and then draw an appropriate amount of the liquid to be tested. Add it to a quartz cuvette, keep it warm for 2-3 minutes at 25±0.1°C, and repeat the measurement three times for each sample. The results showed that the particle size of the lycopene Pickering emulsion was 270±33.12nm.

Embodiment 2

[0055] The content of lycopene in nanoemulsion was determined by high performance liquid chromatography. Standard curve drawing: Accurately weigh 2.1mg of lycopene standard substance, dissolve it in pyrogallic acid-dichloromethane solution to 10mL and make it No. 1 mother liquor. Distribute and draw 10, 50, 100, 500, 1000, 2000 μL in No. 1 mother liquor, put them in six 10mL volumetric flasks, add coke gallic acid-dichloromethane solution to the mark, shake well, and then make lycopene Standard solutions with mass concentrations of 0.2, 1.0, 5.0, 10.0, 20.0, 40.0 μg / mL. The solution is prepared and used immediately. Its purity was determined by liquid chromatography normalization method before use.

[0056] Determination of lycopene content in emulsion: Weigh 1.0g uniform sample and place it in a 25ml brown volumetric flask, add 0.2g pyrogallic acid and 5ml N, N-dimethylamide, ultrasonically extract for 30min, then use pyrogallic acid Dilute the acid-dichloromethane solutio...

Abstract

The invention discloses a preparation method of a lycopene Pickering nano-emulsion and preliminary application of the lycopene Pickering nano-emulsion to food. OSA (octenyl succinic anhydride) modified OSA-glutinous rice starch is dissolved in water to form a water phase, the water phase is mixed with an oil phase formed by soybean oil in which lycopene is dissolved, a stable lycopene nano-emulsion is formed after high-speed shearing and high-pressure homogenization, then spray drying is performed on the nano-emulsion to form OSA-lycopene powder, and the OSA-lycopene powder is added into a soft sweet to implement primary application. The method of the invention is simple in process and convenient to operate. Moreover, the storage stability of the lycopene is greatly improved, and the water insolubility of the lycopene is improved, so that the lycopene can be better applied to food production.

Description

technical field [0001] The invention relates to the technical field related to food processing, in particular to a preparation method of lycopene Pickering nanoemulsion and its preliminary application in food. Background technique [0002] Lycopene (lycopene) is a kind of carotenoid, the appearance is deep red crystal, widely distributed in various mature fruits and vegetables, has a wide range of biological activities, can effectively prevent diseases, prevent cancer, fight cancer, resist Aging is recognized as a type A nutrient by the Food and Agriculture Organization of the United Nations (FAO), the World Health Organization (WHO) and the Joint Expert Committee on Food Additives (JECFA). Lycopene can be used as a nutritional additive and a coloring agent. Its structural diagram is: [0003] [0004] The molecular formula of lycopene is C 40 h 56 , with a molecular weight of 536.85, is a carotenoid with a simple structure (Vogele A C. Effect of environmental factors...
