Fig. 3 is the schematic diagram that shows rigid container described in Fig. 2 state when being subject to hyperpressure.
The specific embodiment
To describe illustrative of the present invention, non-limiting example in detail below, ultrahigh pressure food processing method according to the present invention will be further described.
Below explanation is carried out to HIGH PRESSURE TREATMENT with the method for the blunt enzyme of sterilization according to of the present invention to the food being encapsulated in rigid container.Particularly, will illustrate that illustratively liquid towards food carries out the process of ultra high pressure treatment.
First, the rigid container that is packaged with food is put into ultra high pressure treatment device, the normally liquid or food that contains large quantity of moisture of this food.Then, pressure transmitting medium is full of to this ultra high pressure treatment device.In ultra high pressure treatment device, be full of after pressure transmitting medium, hyperpressure is applied in ultra high pressure treatment device.Described hyperpressure is such as but not limited in the scope of 100MPa～1000MPa.Pressure transmitting medium in ultra high pressure treatment device is delivered to described rigid container by described hyperpressure, thereby the food liquid in this container is carried out to high pressure sterilization.
In the present embodiment, adopt water as pressure transmitting medium.Yet pressure transmitting medium is not limited to this, pressure transmitting medium can also for oil or other there is any material of better pressure transmission characteristic.
Next, with reference to Fig. 1, describe in detail according to the rigid container 10 for food enclosed in sealed of the first embodiment of the present invention.Rigid container 10 comprises container body 11 and the end cap 12 being tightly connected, for example, adopt sealing ring, be threaded, pad or similar fashion be tightly connected.Yet, those skilled in the art will appreciate that the connected mode of container body and end cap is not limited to aforesaid way, and can adopt, can obtain any connected mode being tightly connected.Container body 11 is made by rigid material, and end cap 12 is made by flexible material.When applying hyperpressure in ultra high pressure treatment device, because end cap is made by flexible material, so end cap shrinks in container in response to the hyperpressure of water transmission.Therefore, pressure can be delivered to the food liquid in container immediately, thereby the pressure that contends with produce equating is guaranteed that thus container can crushed or distortion during HIGH PRESSURE TREATMENT, thereby the food in rigid container is carried out to the blunt enzyme of sterilization.
Further, container body 11 is by making such as the rigid material of glass or metal, but the rigid material of formation container body is not limited to glass or metal, and can be for obtaining any rigid material of packing visual effect attractive in appearance.Existing ultrahigh pressure food processing method is to be all applied to flexible packaging food.The barrier of flexible package is poor, and oxygen, steam etc. are easily infiltrated during ultra high pressure treatment from packing, therefore reduces food quality.In addition, flexible packing material and food interact, and the packaged material of food taste is absorbed, thereby reduce flavour of food products.In addition, in the packaging material polymer of flexible package, such as the little molecular weight of plasticizer, residual monomer etc. and the composition of middle molecular weight, not with chemical bond and polymer chain combination, therefore easily from polymer, move out, thereby contaminated food products, and then affect food security.Ultrahigh pressure food processing method according to the present invention is applied to rigid container, and the main body of this container is made by the rigid material such as glass, the problems referred to above that therefore can avoid flexible package to bring.
For example, end cap 12 can be made by plastic material.Preferably, end cap can be by SBS (SEBS(styrene ethylene butylenes styren)) make.SEBS has good draftability and air-tightness, UV stable, antioxidant and heat endurance preferably, and nontoxic and therefore can use thermophilic digestion and disinfection by ultraviolet light.Alternatively, end cap can also be made by polyurethane (PU).PU chemical stability is good, can resist the corrosion of multiple soda acid and organic solvent, nonpoisonous and tasteless, has high strength, all insensitive to temperature, humidity and ultraviolet ray, therefore not perishable in storing process.Yet the material that end cap is used is not limited to above-mentioned material, and can make by thering is high stretch, heatproof, anti-aging, nonpoisonous and tasteless any elasticity non-toxic material, for example polystyrene, polyethylene or similar material.
The rigid container being applied to due to ultrahigh pressure food processing method according to the present invention has above-mentioned flexible end cap, and therefore, when carrying out super high pressure food processing, end cap can shrink in rigid container.As shown in Figure 1, rigid container 10 integral body are subject to hyperpressure.The food liquid of rigid container 10 interior encapsulation contains large quantity of moisture conventionally, and the volume of water is very large the reducing of nothing under pressure.The amount of contraction of flexible end cap 12 is preferably more than 10% of vessel volume, makes the amount of contraction of end cap be greater than the volume decrease of food liquid in container, and end cap can be because pressure rises brokenly thus.Therefore, the food that ultrahigh pressure food processing method according to the present invention can be used in being encapsulated in rigid container carries out ultra high pressure treatment to realize the blunt enzyme of sterilization, and obtains the packing with better texture and visual effect attractive in appearance.
Next, with reference to Fig. 2 and Fig. 3 explanation rigid container according to a second embodiment of the present invention.Fig. 2 is according to the structural representation of the rigid container of described the second embodiment.According to the rigid container of described the second embodiment to according to the rigid container of described the first embodiment, there is similar structure, difference is only that the rigid container of described the second embodiment is also provided with stopper.
As shown in Figure 2, rigid container 20 comprises container body 21, end cap 22 and stopper 23, and described container body is connected with described end cap seal.Stopper 23 is arranged on the below of end cap 22.When carrying out super high pressure food processing, flexible end cap 22 is subject to hyperpressure and to the interior contraction of rigid container 20, promotes stopper 23 simultaneously and slide (as shown in Figure 3) to the inside of rigid container 20.This make rigid container can be due to hyperpressure during ultra high pressure treatment crushed or distortion.Stopper 23 can be made by cork, silicon rubber, TPE flexible glue or similar environment-friendly materials.Because the rigid container of the present embodiment is provided with stopper, therefore can prevents that any material from permeating away during ultra high pressure treatment in container, thereby more effectively improve food quality.
