Embodiment 1

[0036] The edible sunflower protein anti-oxidation packaging material of this embodiment comprises the following components in parts by weight: 100 parts of sunflower protein and 20 parts of bovine plasma protein hydrolyzate.

[0037] Described sunflower seed protein is prepared by following method:

[0038] a) Take sunflower seed meal powder (the sunflower seed meal powder is made by passing sunflower seed meal through a 60-mesh sieve after being pulverized by a high-speed universal grinder), according to the ratio of material to liquid 1:15 (w / v) Add sunflower seed meal powder to distilled water, stir for 1 hour, adjust the pH to 9 with NaOH solution with a concentration of 3 mol / L, and centrifuge at 3500 r / min for 20 minutes to obtain supernatant and residue;

[0039] b) Extract the residue once more according to the method of step a), and combine the supernatants extracted twice to obtain the mixed solution A;

[0040] c) Use hydrochloric acid with a concentration of 3 mo...

Embodiment 2

[0052] The edible sunflower protein anti-oxidation packaging material of this embodiment contains the following components in parts by weight: 100 parts of sunflower protein and 25 parts of bovine plasma protein hydrolyzate.

[0053] Described sunflower seed protein is prepared by following method:

[0054] a) Take sunflower seed meal powder (the sunflower seed meal powder is made by passing sunflower seed meal through a 60-mesh sieve after being pulverized by a high-speed universal pulverizer), according to the ratio of material to liquid 1:14 (w / v) Add sunflower seed meal powder into distilled water, stir for 0.9 h, adjust the pH to 8.5 with NaOH solution with a concentration of 3 mol / L, and centrifuge at 3500 r / min for 25 min to obtain supernatant and residue;

[0055] b) Extract the residue once more according to the method of step a), and combine the supernatants extracted twice to obtain the mixed solution A;

[0056] c) Use hydrochloric acid with a concentration of 3 m...

Embodiment 3

[0068] The edible sunflower protein anti-oxidation packaging material of this embodiment contains the following components in parts by weight: 100 parts of sunflower protein and 30 parts of bovine plasma protein hydrolyzate.

[0069] Described sunflower seed protein is prepared by following method:

[0070] a) Take sunflower seed meal powder (the sunflower seed meal powder is made by passing sunflower seed meal through a 80-mesh sieve after being pulverized by a high-speed universal pulverizer), according to the ratio of material to liquid 1:16 (w / v) Add sunflower seed meal powder to distilled water, stir for 1.1 h, adjust the pH to 9.5 with NaOH solution with a concentration of 3 mol / L, and centrifuge at 3500 r / min for 15 min to obtain supernatant and residue;

[0071] b) Extract the residue once more according to the method of step a), and combine the supernatants extracted twice to obtain the mixed solution A;

[0072] c) Use hydrochloric acid with a concentration of 3 mol...

Abstract

The invention discloses an edible sunflower seed protein antioxidant packaging material and a preparation method thereof. The antioxidant packaging material comprises the following components in parts by weight: 100 parts of sunflower seed protein, and 20-30 parts of bovine plasma protein hydrolysate. According to the edible sunflower seed protein antioxidant packaging material provided by the invention, the bovine plasma protein hydrolysate is compounded with the sunflower seed protein, so that the obtained edible packaging material has good mechanical strength, ultraviolet barrier properties and water vapor transmission resistance. Compared with a simple sunflower seed protein membrane, the resistance to oxidation is obviously enhanced, and oxidative rotting of the food can be effectively prevented, so that the effects of preserving the food and prolonging the shelf life are achieved; the obtained packaging material has edibility, can be biodegraded, and does not lead to pollution to the environment; the raw materials are renewable resources; the packaging material is low in production cost, and can replace other packaging materials; the non-renewable resources are greatly saved; the edible sunflower seed protein antioxidant packaging material is applicable to popularization and application.

Description

technical field [0001] The invention belongs to the technical field of edible packaging materials, specifically relates to an edible sunflower protein anti-oxidation packaging material, and also relates to a preparation method of the edible sunflower protein anti-oxidation packaging material. Background technique [0002] In my country, the deep processing of sunflower is generally limited to extracting its oil, and the sunflower seed meal produced in the processing process is basically used as cheap animal feed, which has not been fully and effectively utilized. Cattle blood is a by-product of slaughtered cattle, which is large in quantity and has high development and utilization value. However, cattle blood has not been well utilized for a long time, and is basically in a state of being abandoned. Not only the loss of protein resources, but also serious environmental pollution. According to the statistics of the environmental protection department, the pollution load BOD p...
