Abstract

The invention relates to a method for preparing edible wrapping paper by taking celeries as raw materials, and the method comprises the following steps: selecting fresh and undecomposed celeries, and removing the roots of the selected celeries and impurities in the selected celeries, then after cleaning the obtained celeries with clean water, cutting the cleaned celeries into pieces; after blanching the obtained celery pieces for 8-15 minutes in a 0.5% (w/v) sodium chloride solution at a temperature of 95-100 DEG C, beating the obtained product; and after 3-5% (w/v) adding milk and gelatins into the obtained 15-35% (w/v) serosity, homogenizing the obtained mixture, then adding carrageenan, glycerin, green tea polyphenols and chitosan into the obtained feed liquid subjected to homogenizing, and carrying out die-pressing forming on the obtained mixture so as to obtain the edible wrapping paper prepared by taking the celeries as the raw materials. The edible wrapping paper prepared by the method provided by the invention is emerald green, and has exquisite quality and special celery fragrance, therefore, the edible wrapping paper can be used as a leisure food and used for the exterior and interior packing of food.

Description

A kind of preparation method of edible wrapping paper with celery as raw material

technical field

The invention relates to a preparation method of edible wrapping paper, in particular to a preparation method of edible wrapping paper using celery as a raw material.

Background technique

Packaging has two major functions: one is to protect the goods from damage and deterioration during the process of manufacturing, transportation, warehousing and sales; It meets the increasing material and cultural needs of consumers, and promotes and stimulates consumption. As an important packaging material, packaging paper has been widely used in product packaging in various industries. It includes container board and corrugated base paper, white cardboard and white cardboard, beverage flexible packaging paper, special packaging paper, etc. Packaging paper is a major category in the paper industry, and its output accounts for about 56% of the total output of paper and paperboard. Among all kinds of packaging products, paper packaging accounts for more than 50%, ranking first among all kinds of packaging materials. From the perspective of output value, paper product packaging materials are the second largest category of packaging materials in my country after plastics. With the emergence of crises such as environmental deterioration, lack of resources, and energy shortages, people have proposed a new concept in the field of packaging—green packaging. Green packaging can also be called pollution-free packaging and environmentally friendly packaging. It mainly has two meanings: protecting the environment and saving resources, and saving resources can also reduce waste emissions. For green packaging materials, the typical representative is that edible packaging materials have important environmental protection and economic value. At present, there are two types of edible wrapping paper in foreign countries. One uses vegetables as the main raw material, and the vegetables are beaten and then dried; the other is made of starch and sugar into paste, and other food additives are added. method of shaping.

The common feature of vegetable food is that it is rich in dietary fiber, multiple vitamins and minerals. Among them, dietary fiber is quite stable in processing and production, so the processed paper vegetable products have little nutritional loss and low water content (about 10%) , easy to transport and store. It not only improves the added value of vegetables, but more importantly, solves the problem that vegetables are perishable and difficult to store. Paper vegetables can be used in many fields such as convenient snack food and edible packaging.

Celery is a vegetable with high nutritional and medicinal value. It contains celery 2, bergamot lactone, volatile oil, organic acid, carotene and various vitamins, minerals, etc., among which vitamin P and minerals contain calcium, phosphorus, Iron is rich in iron, which has the effect of calming and protecting blood vessels to the human body. Pregnant women, nursing mothers, iron deficiency anemia, high blood pressure, arteriosclerosis, neurasthenia and other patients are very beneficial if they eat it regularly. Celery leaves contain many vitamins.

Contents of the invention

The purpose of this invention is to provide a kind of preparation method of the edible wrapping paper that takes celery as raw material, the edible wrapping paper texture that prepares with this method is fine and smooth, bright green in color, the special fragrance of tool celery, can be used as leisure food, As well as the inner and outer packaging of convenience food, fast food, cakes, condiments and other foods.

In order to achieve the above object, the present invention adopts the following technical scheme: a kind of preparation method of edible wrapping paper with celery as raw material, it is characterized in that, select fresh, non-deteriorated celery for use, remove root and impurity, after washing with clear water, cut block; blanching in 0.5% (w/v) sodium chloride solution at 95-100°C for 8-15 minutes and beating; adding 3-5% (v/v) Homogenize milk with 1-3% (w/v) gelatin, add 1-3% (w/v) carrageenan, 1-3% (v/v) glycerin, 0.2-0.4% (v/v) green tea polyphenols and 0.5-1.0% (w/v) chitosan are press-molded to obtain edible wrapping paper made of celery as a raw material.
