Abstract
The present invention relates to production method of edible plant leaf protein, lactic acid is used to precipitate the leaf protein at a certain temperature, theraby implements sterilization and precipitation in one single operation, the invented method possesses the advantages of simple technology and shorter time and is suitable for automation.
Description
The present invention relates to the method that a kind of plant edible food leaf protein precipitation is produced.
Along with the development of food industry and the raising of living standards of the people, pollution-free food is subjected to that people are deeper and deeper to be liked, extracts leaf protein from plant, be each state all in the problem of research, and the difficult problem of this technology maximum is the sedimentation problem of leaf protein.At present, the intermediate processing of domestic research roughly has two kinds: the one, adopt heating, and be about to be heated to more than 120 ℃ behind the plant expressed juice, leaf protein is solidified precipitate; The 2nd, adopt to add acid system, at normal temperatures promptly, will add certain density lactic acid in the water, make the leaf protein precipitation, be 93111694.5 described precipitation method for producing plant leaf protein as the patent No..Though above-mentioned two kinds of methods respectively have advantage, and the some shortcomings part is also arranged, though the heating method is simple, power consumption is high, and sedimentation effect is bad, and because the temperature height, the protein of precipitation easily hardens, and influences product quality; The patent No. be 93111694.5 introduced though to add acid system energy-conservation, province's equipment is not limited by scale, but the sedimentation time needs more than 8 hours, in following process, also need sterilizing, and the method introduced of this patent is to produce forage protein, requires also not high product quality.
The object of the present invention is to provide and a kind ofly can accelerate settling velocity, can guarantee the method that the plant edible food leaf protein precipitation of sedimentation effect is produced again.
The present invention all can make plant leaf protein solidify the principle of precipitation according to heating or adding lactic acid, process characteristic according to plant edible food leaf protein necessary sterilizing in the processing process, to heat and add two kinds of methods of lactic acid and merge in process of production, and not only heat but also add acid.The purpose of heating is to make plant juice sterilizing on the one hand, is that the leaf protein in the water is solidified to a certain extent on the other hand; The purpose that adds lactic acid is further to solidify plant leaf protein, guarantees the effect of precipitation.Promptly earlier water is heated to required temperature, cools off a period of time then, add lactate buffer solution again, like this, only need just be precipitated to required effect in 2～3 hours to certain temperature.Therefore, both finish the technical process of sterilizing, accelerated the settling velocity of solidifying of plant leaf protein again.
Since adopted technique scheme, the present invention have that technology is simple, settling velocity is fast, effective, need not increase special equipment, be not subjected to characteristics such as scale restriction, be adapted to automated production and use.According on probation, adopt this method sedimentation time only to need normal temperature to add acid system
, sedimentation effect is better than normal temperature and adds acid system.
Below the present invention is further described: the fresh plant raw material is cleaned the back pulverize, be delivered to squeezer and press juice, its purpose is to destroy the collastromin in the raw material, to increase the output of protein.Plant juice after the squeezing enters in the thermotank after filtering, and juice is heated to 80～100 ℃ solidifies and sterilization, is cooled to 40～50 ℃ then.Add lactate buffer solution, precipitate after 2～3 hours, sop up top supernatant, the egg white icing that precipitates is discolored to remove astringent taste again equal the following process of dry finished product.The supernatant that sops up can repeat fermentation and use.The quantity of thermotank can be according to the production scale setting, to guarantee continuous production.
(embodiment) delivers to fresh string leaf prairie dock cleaning and chopping and presses juice in the squeezer, sends in the thermotank after water being filtered again.With vavuum pump the water in the thermotank is heated to 90～100 ℃, is cooled to then about 40 ℃, add 5～8% lactate buffer solution again and make its mixed precipitation.Plant leaf protein precipitates in thermotank, and the supernatant of post precipitation can be used as precipitated liquid and recycles by the suction pipe sucking-off, and the leaf protein cream of post precipitation sends into that back segment discolors, removes astringent taste, the back processing of dry finished product is handled.
Claims (1)
- A kind of plant edible food leaf protein adds acid precipitation production method, plant is pulled an oar, squeezes the juice, makes precipitating reagent with lactic fermentation liquid, it is characterized in that earlier water being heated to 80～100 ℃, be cooled to 40 ℃～50 ℃ then and add lactic fermentation liquid again and precipitate.
