Problems solved by technology

[0004] The current method for preparing powdered lycopene is mainly to mix wall materials such as gelatin, sucrose or maltodextrin with lycopene and then spray dry. The process is relatively complicated.
Porous starch is a natural non-toxic substance with low price, and its adsorption is unstable, volatile, and easily oxidized, but it is rarely used in lycopene

Embodiment 1

[0013] Embodiment 1: a kind of preparation method of powder lycopene of the present invention, method step is as follows:

[0014] Step 1: Weigh 30g of corn starch and place it in a Erlenmeyer flask, prepare 40% starch milk with distilled water, put it in a 35°C water bath to preheat for 5 minutes, adjust the pH value to 9 with 3% NaOH solution, and then slowly add Mixed acid accounting for 5% of the dry basis of corn starch, shake in a water bath at 35°C for 2.5 hours, keep the pH value of the system constant during the reaction, adjust the pH value to 6.5 with 0.1mol / L hydrochloric acid after the reaction, filter with suction, wash, dry, and pulverize , to obtain mixed acid crosslinked starch;

[0015] Step 2: Weigh 20g of the mixed acid-crosslinked starch prepared in Step 1 and place it in a reaction bottle, add sodium acetate-acetic acid buffer solution with pH 5.0 to make 15% starch milk, and place it in a constant temperature water bath at 45°C for preheating 10 min; ad...

Embodiment 2

[0018] Embodiment 2: A preparation method of powdered lycopene of the present invention, selection of cross-linking agent: mixed acid (citric acid, acetic anhydride); screening of raw amylase: combined use of α-amylase and glucoamylase. The preparation process of powdered lycopene:

[0019] ① Weigh 30g of cornstarch and put it in a Erlenmeyer flask, prepare 40% starch milk with distilled water, put it in a 35°C water bath to preheat for 5 minutes, adjust the pH value to 9 with 3% NaOH solution, then slowly add 5% (accounting for starch dry basis) mixed acid (citric acid: acetic anhydride = 1:50), shake in a water bath at 35°C for 2.5 hours, and keep the pH value of the system constant during the reaction. After the reaction, adjust the pH value to 6.5 with 0.1 mol / L hydrochloric acid, filter with suction, wash, dry, and pulverize to obtain mixed acid crosslinked starch.

[0020] ② Weigh 20g of self-made mixed acid-crosslinked starch and put it in a reaction bottle, add sodium...

Abstract

The invention provides a preparation method of powdery lycopene, wherein the preparation method can improve the stability of lycopene, prolong the storage time and expand the application range of lycopene, and the powdery lycopene is embedded by taking the cross-linked porous starch as a wall material. The preparation method comprises the following steps: placing 30 g of corn starch in a conical flask, and preparing 40% starch milk with distilled water; pre-heating the starch milk in a water bath kettle at 35 DEG C for 5 minutes; regulating the pH value to 9 with a 3% NaOH (sodium hydroxide) solution; filtering, washing, drying and crushing to obtain the mixed acid cross-linked starch; adding a sodium acetate-acetic acid buffer solution with the pH value of 5.0 to the mixed acid cross-linked starch to prepare 15% starch milk and obtain the cross-linked porous starch; mixing the cross-linked porous starch with excessive pigment oil and stirring for absorption; and performing vacuum filtration and vacuum drying to obtain the powdery lycopene product. After the lycopene is embedded by the cross-linked porous starch, the stability of the lycopene against light and heat is remarkably improved, and the storage time of the lycopene is prolonged.

Description

(1) Technical field [0001] The invention relates to food technology, in particular to a preparation method of powdered lycopene. (2) Background technology [0002] Lycopene (Lycopene) is an important open-chain unsaturated carotenoid with the strongest antioxidant activity among carotenoids. It is composed of two elements, carbon and hydrogen, and its molecular formula is C 40 h 56 , the molecular weight is 536.88. Lycopene is the main pigment in mature tomatoes, and its content can reach 3-14mg / 100g, and the higher the maturity of tomato, the higher the lycopene content, and its content in some varieties of tomatoes can reach as high as 40mg / 100g. The melting point of lycopene is 174°C, and its color is red. When the molecule transforms from anti-constitution to cis-constitution, the color becomes lighter, the melting point decreases, the extinction coefficient decreases, and the absorption peak shifts. It is insoluble in water, hardly soluble in polar organic solvents s...
