Example Embodiment

Example 1

Formula ratio (parts by weight)

Glucomannan 0.8, tomato clear juice 8, sorbitol 8, gelatin 6, protamine 0.09, water 85.

Preparation method of tomato edible film:

(1) Weigh 8 grams of glucomannan, dissolve it in 800 grams of water, and soak for 12 hours at a temperature of 15℃±2℃;

(2) Add 80 grams of sorbitol, 60 grams of gelatin, and 80 grams of tomato clear juice to the glucomannan solution in sequence, and stir for 20-30 minutes at a temperature of 60℃±2℃ and a speed of 600~800rpm. Heat it to 90℃±2℃, keep it for 6-8 minutes;

(3) Adjust the pH value to 8.0-8.5 with 10% edible sodium phosphate solution, add 0.9 g of protamine, stir well and let stand for 2-3 hours to form a film-forming solution;

(4) Pour the film-forming solution on a flat plate, scrape the film to form a uniform film with a certain thickness, dry it at a temperature of 60℃±2℃, and remove the film to obtain an edible tomato film.

Example Embodiment

Example 2

Formula ratio (parts by weight)

Glucomannan 1, tomato clear juice 10, sorbitol 10, gelatin 7, protamine 0.1, water 90.

Preparation method of tomato edible film:

(1) Weigh 10 grams of glucomannan, dissolve it in 900 grams of water, and soak for 12 hours at 15°C±2°C;

(2) Add 100 grams of sorbitol, 70 grams of gelatin, and 100 grams of tomato clear juice to the glucomannan solution in sequence. Stir for 20-30 minutes at a temperature of 60℃±2℃ and a speed of 600~800rpm. Heat it to 90℃±2℃, keep it for 6-8 minutes;

(3) Adjust the pH value to 8.0-8.5 with 10% edible sodium phosphate solution, add 0.9 g of protamine, stir well and let stand for 2-3 hours to form a film-forming solution;

(4) Pour the film-forming solution on a flat plate, scrape the film to form a uniform film with a certain thickness, dry it at a temperature of 60℃±2℃, and remove the film to obtain an edible tomato film.

Abstract

The invention provides an edible tomato film which comprises the following raw materials in parts by weight: 0.6-1 part of glucomannan, 5-10 parts of clear tomato juice, 6-10 parts of sorbitol, 5-7 parts of gelatin, 0.08-0.1 part of protamine and 80-90 parts of water. Meanwhile, the invention provides a preparation method of the edible tomato film. The prepared edible tomato film can be used for packaging ready-to-eat foods such as candied fruits, instant drinks and candies, has a flavor of tomatoes and is pink in appearance; the eating convenience and the eating interestingness of packaged foods are improved.

Description

technical field [0001] The invention belongs to the field of food processing and relates to packaging films, in particular to a tomato edible film. Background technique [0002] Edible packaging film (EPF), referred to as edible film, is a film with a porous network structure formed by the interaction of different molecules with natural edible substances (such as polysaccharides, proteins, etc.) as raw materials. Edible film has the advantages of easy degradation, edible, convenient use, and no pollution to the environment. It is a food packaging material with great development potential and has a good development prospect. At present, edible films have been widely used in food packaging, but the variety of edible films is too single, usually colorless, odorless, transparent films, which cannot meet the needs of diversified food and differentiated packaging. Contents of the invention The invention provides a tomato edible film, which can be used for the packaging of di...
