Definitions
- the present invention relates to a method for efficiently producing a food having no deforming force such as nets generated when a soft water-containing light food of S ⁇ is frozen in a rose and free from cracks caused by freezing. It is.
- the soft hydrated food of SIS ⁇ solidifies on the support during the freezing process, and if this is attempted, it takes time and effort and damages the tissue with unreasonable force There's a problem. Furthermore, there is a problem of cracking unless there is a special ingenuity to allow the freezing device to distribute the heat evenly. It is presumed that this cracking is due to the fact that you expand when frozen, the contents of the part where the freezing is delayed are pushed out by the internal pressure, and the tissue partially collapses. In order to prevent this cracking, a method has been proposed in which the soft water-containing food is conditioned to the temperature immediately before freezing, and the inside and outside of the food is cooled uniformly (Japanese Patent Application Laid-Open No.
- the method is «the preferred method of cooling, but it is not possible to solve the problem of sticking on the support, without cooling in the container, without the force, the force, and the small size of the food It is difficult to freeze the so-called roses inexpensively There was a problem. Disclosure of the invention
- An object of the present invention is to provide a method of producing a soft water-containing food that does not cause deformation of a net or the like and does not cause cracking.
- the present invention has completed the present invention while continuing further research on whether or not it is possible to prevent freezing and to prevent freezing even if the cooling is not performed in a container without cooling in a container.
- the present inventors freeze a soft hydrated food product on a smooth flat support, roll it after starting freezing, or transfer it to a different support to further freeze it.
- a method for manufacturing frozen foods In the present invention, the rolling or transfer is preferably performed in the maximum ice crystal forming zone, and the soft water-containing food is indicated by the strength of tofu processed foods such as fungi, fried tofu, and potato mushrooms.
- a flat steel belt is exemplified as the smooth flat support
- a ventilated support is exemplified as the different support
- Rolling or transfer is preferably performed at 1/5 to 4Z5 of the passage time of the maximum ice crystal formation zone after the start of freezing. Further, when the [soft] food is transported to the freezing equipment, it is preferable that the pier having an upwardly convex curved surface with respect to the transport surface is spaced apart and transported to the smooth flat support by a conveyor attached. And this invention relates to the foodstuff obtained by these methods.
- the present invention is directed to a method for efficiently producing a food product that is less likely to deform the nets and the like generated when the food product is frozen and that has less cracks due to the formation of ice crystals.
- the method for producing the frozen food used in the present invention may be an ordinary method except for those described later. First, terms of the present invention will be described.
- Cracking means that the product expands when the water freezes, the product freezes slowly, internal pressure is applied to the part, and the contents come out from the surface.
- Deformation of nets and the like means that the mold force of the support such as net wires remains on the surface of the frozen food.
- the food freezing »operation is a cooling operation that removes heat from the food.
- the food By actively removing heat from the food, the food rapidly drops, and eventually the water inside the food changes its phase from liquid to solid. After reaching the freezing point and reaching the freezing point of the food, the food begins to fall again and eventually reaches a key that is equilibrium with the ambient temperature.
- the time zone during which freezing is progressing is called the maximum ice crystal formation zone.
- Soft water-containing foods are foods that are soft enough that the food obtained by blending, molding, cooking, etc., the raw material is deformed by its own weight along the shape of the contact surface in a non-freezing water-containing state.
- Typical examples are west, fried tofu, si roe foods such as potatoes, rice cakes, and the like, and the moisture content is approximately 70% or more, depending on the difficulty. It can be frozen even if it is in a loose or loose state when placed in a container.
- the smooth flat support is a flat support having a smooth surface and no perforations or the like that allow ventilation from the back. It is usually in the form of an endless strip for transportation, and typically a steel flat belt made of steel can be used.
- Rolling or transporting refers to reversing the food on a smooth planar support or transferring it to a different support.
- a support that can ventilate is a support capable of blowing cool air, and a net belt or the like woven into a net with a steel or the like. Freezing with only each belt has the following problems. If frozen only with a steel flat belt, the soft ⁇ ] food will crack, and will adhere firmly to the belt, and a strong impact is required to remove it. In this case, if the product is filled and packaged as it is, the products tend to adhere to each other. Next, when it is frozen with only the net belt, it becomes deformable, such as the appearance of a net.
- the soft food containing the food before freezing bites into the net, and a deformation force such as a net is generated in the product.
- the passage time of the maximum ice crystal formation zone after the start of freezing in the process of freezing the soft water-containing food is shorter than the point of 1 Z5, the surface layer is in a soft state. It is difficult to prevent deformation of eyes etc. Also, it is longer than 4/5, and the prevention of cracking is not enough. More preferably, rolling or transferring at 1/3 to 2 Z 3.
- the passage time of the maximum ice crystal formation zone in the step of freezing the soft water-containing food is shorter than 1 minute, the freezing is too rapid, and the cracking force is easily generated.
- a force depending on the size of the product preferably 2 minutes or more.
- the soft i food is deformed when it is transported to the freezing step, the meaning of the present invention is weakened, and the desired product cannot be obtained.
- a conveyor in which a pier having an upwardly convex curved surface with respect to the transfer surface is attached at an interval.
- "Pier” is a so-called It is equivalent to a slat that is attached between the two rollers and one roller chain of the rat conveyor, and its shape is “with a convex curved surface on the transfer surface”. Coupled with the placement of the babies at intervals, the soft hydrated food does not slide down even if there is a difference in height before and after transport in the valley of the curved convex surface, and is therefore hardly broken and transported well.
- the soft, water-containing food thus frozen may be used as a frozen food as it is, or may be used as a freeze-dried food.
- the freezing machine (Fujitetsumo Co., Ltd .: Jet Freezer-1) freezes at 135 ° C, wind speed is 15mZsec, and the maximum ice crystal formation zone transit time is 2 minutes. One minute after passing through the maximum ice crystal formation zone (1/2 time point), the sample was placed on a net conveyor and frozen to 18 ° C.
- Example 1 The shape was cut into 4 Omm squares (weight 64 g). The transit time of the maximum ice crystal formation zone is 15 minutes.
- Example 1 Example 7 except that it was transferred to a net conveyor 6 minutes after passing into the maximum ice crystal formation zone (at 2/5).
- Example 1 was followed, except that at the time of entering the maximum ice crystal formation zone, the wafer was transferred to a net conveyor.
- Example 1 was followed except that the sample was transferred to a net conveyor immediately after the maximum ice crystal formation.
- Freezing is performed at 45 ° C, wind speed is 25 m / sec, and the passage time through the maximum ice crystal formation zone is rapid for 50 seconds.
- Example 1 was followed, except that 25 seconds after passing through the maximum ice crystal formation zone (time point 1 and 2), the wafer was transferred to a net conveyor.
- Example 2 was followed, except that at 2 minutes after passing into the maximum ice crystal formation zone (1 / 7.5 time point), the sample was transferred to a net conveyor.
- Example 2 12 minutes after passing into the maximum ice crystal formation zone (at 6 / 7.7.5) Example 2 was followed, except that
- the soymilk and the coagulated material were supplied on the moving belt, coagulated in a fiber under a heated atmosphere, and then cut into 15 thighs.
- a steel-pelt type in a post-process with a transfer angle of 10 degrees and a step of 2 m It is transported to a freezer and frozen at 5 ° C, and the wind speed is 15 m / sec.
- the passage time through the maximum ice crystal formation zone is 2 minutes.
- One minute after passing through the maximum ice crystal formation zone (1/2 time point) transfer to a net conveyor, freeze to 18 ° C, and evaluate the product. There was no deformation such as nets, and it was a good storehouse. Possibility of using illusion il
- the present invention makes it possible to produce a soft, water-containing food that is free from deformation due to deformation of the net or the like even when frozen, and does not crack due to the formation of ice crystals.
