A kind of is the preparation method of the edible wrapping paper of raw material with the corn peel
Technical field
The present invention relates to a kind of preparation method of edible wrapping paper, particularly relating to a kind of is the preparation method of the edible wrapping paper of raw material with the corn peel.
Background technology
Pack in modern times in the four big materials (paper, plastics, glass and metal),, can cause environmental pollution because plastic package material is difficult for degraded voluntarily; The glass packaging material is prone to broken in handling process, the difficult recovery, and utilize cost high again; Metal packing material is expensive; Therefore, paper packing material is used more extensive in daily life, and is more friendly to environment.Along with the appearance of crises such as ecological deterioration, resource plaque lack, energy shortage, people propose a kind of new theory---green package to packaging field.Green package can be called the friend packing of nuisanceless packing and environment again, refer to ecological environment and health harmless, can round-robin and regeneration, can promote the packing of sustainable development, i.e. low energy consumption, new green, utilization again, capable of circulation and can degrade.Typicalness is represented as the edible packaging material for environmentally friendly packing material.
Wrapping paper has been widely used in the packing of product of every profession and trade as a kind of important packaging material, and it has comprised boxboard and fluting medium, white board and art post paperboard, soft package of beverage paper, special packing paper etc.Wrapping paper is a big kind of paper industry, and output accounts for 56% of paper and cardboard total output.In all kinds of packing articles, the stationery packing accounts for more than 50%, occupies first of the various packaging material.From the output value, the packaging paper product material is the second largest based packaging material that China is only second to plastics.
Corn is one of most important three generalized grain crops in the world today, and cultivated area and total output are only second to paddy rice and wheat, but its yield per unit area occupies the first, and corn has become grain, feed and raw material of industry dual-purpose crop.China is second-biggest-in-the-world Maize Production state, and present 80% corn is with the directly listing or directly consume through preliminary working of raw grain state, and the corn deep processing industry is very undeveloped.
China mainly concentrates on the production of feed and starch to the processing of corn.But for corn processing back byproduct---the research that corn peel utilizes again also seldom and is in quite low level, a lot of enterprises only with it as feed or discarded, cause the very big wasting of resources.Some composition of corn peel or component (like dietary fiber, corn lipopolysaccharides, maize voxel and luteole etc.) research also seldom perhaps is in quite low level, is rationally utilized.
" a kind of is the preparation method of the edible wrapping paper of raw material with the corn peel " invention fully rationally utilizes the corn resources advantage, improves the corn comprehensive utilization ratio, can produce good economic benefits and social benefit.
Summary of the invention
The purpose of this invention is to provide a kind of is the preparation method of the edible wrapping paper of raw material with the corn peel; In this way yellowish, the no special odor of edible wrapping paper color of preparation can be used as the exterior and interior packing of food such as instant food, fast food, cake, flavouring.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: a kind of is the edible wrapping paper of raw material with the corn peel; It is characterized in that it is 100~120 orders that corn peel is pulverized the back particle size range, mixes making concentration reach 20~40% (w/v) with water; 50 ℃~75 ℃ of temperature, sonicated is 5~10 minutes under ultrasonic power 200W~400W condition; Be cooled to 40 ℃~60 ℃, add the lipase of 1% (w/w)~3% (w/w) and the mixing enzyme preparation of protease (ratio of lipase and protease is 3: 1~1: 3) in the feed liquid, enzymolysis is 50~80 minutes under pH4.5~6.5 conditions.The glycerine that adds 0.3~0.5% (w/v) in the feed liquid behind the enzymolysis adds konjac glucomannan 0.20~0.4% (w/w), carragheen 0.1~0.3% (w/w), and dry obtaining with the corn peel is the edible wrapping paper of raw material behind the roll-forming.
It is 100~120 orders that corn peel is pulverized the back particle size range, mixes making concentration reach 20~40% (w/v) with water.
Feed liquid is under 50 ℃~75 ℃ of temperature, and sonicated is 5~10 minutes under ultrasonic power 200W~400W condition.
Feed liquid after the sonicated is cooled to 40 ℃~60 ℃, adds the lipase of 1% (w/w)~3% (w/w) and the mixing enzyme preparation of protease (ratio of lipase and protease is 3: 1~1: 3) in the feed liquid, and enzymolysis is 50~80 minutes under pH4.5~6.5 conditions.
The glycerine that adds 0.3~0.5% (w/v) in the feed liquid behind the enzymolysis adds konjac glucomannan 0.20~0.4% (w/w), carragheen 0.1~0.3% (w/w), and dry obtaining with the corn peel is the edible wrapping paper of raw material behind the roll-forming.
The specific embodiment
Embodiment 1: it is 100 orders that corn peel is pulverized the back particle size range, mixes making concentration reach 20% (w/v) with water, 75 ℃ of temperature, and sonicated is 10 minutes under the ultrasonic power 200W condition; Be cooled to 60 ℃, add the mixing enzyme preparation (ratio of lipase and protease is 1: 1) of 1% (w/w) lipase and protease in the feed liquid, enzymolysis is 50 minutes under the pH5.5 condition.The glycerine that adds 0.4% (w/v) in the feed liquid behind the enzymolysis adds konjac glucomannan 0.20 (w/w), carragheen 0.3% (w/w), and dry obtaining with the corn peel is the edible wrapping paper of raw material behind the roll-forming.
Embodiment 2: it is 120 orders that corn peel is pulverized the back particle size range, mixes making concentration reach 40% (w/v) with water, 50 ℃ of temperature, and sonicated is 5 minutes under the ultrasonic power 400W condition; Be cooled to 40 ℃, add the lipase of 3% (w/w) and the mixing enzyme preparation of protease (ratio of lipase and protease is 2: 1) in the feed liquid, enzymolysis is 80 minutes under the pH4.5 condition.The glycerine that adds 0.3% (w/v) in the feed liquid behind the enzymolysis adds konjac glucomannan 0.4% (w/w), carragheen 0.1% (w/w), and dry obtaining with the corn peel is the edible wrapping paper of raw material behind the roll-forming.
Embodiment 3: it is 110 orders that corn peel is pulverized the back particle size range, mixes making concentration reach 30% (w/v) with water, 60 ℃ of temperature, and sonicated is 8 minutes under the ultrasonic power 300W condition; Be cooled to 50 ℃, add the lipase of 2% (w/w) and the mixing enzyme preparation of protease (ratio of lipase and protease is 1: 2) in the feed liquid, enzymolysis is 60 minutes under the pH5.0 condition.The glycerine that adds 0.4% (w/v) in the feed liquid behind the enzymolysis adds konjac glucomannan 0.3% (w/w), carragheen 0.2% (w/w), and dry obtaining with the corn peel is the edible wrapping paper of raw material behind the roll-forming.
