JPS5843738A - Preparation of thick flake of dried fish - Google Patents

Abstract

PURPOSE:To prepare thick flakes of dried fish with eliminating steaming process, by immersing dried fish in water, allowing it to stand so that water is penetrated into the interior, treating it with hot air, sending it to a shaver. CONSTITUTION:A dried fish with mold on it is immersed in water within 10min., the dried fish is pulled out of water, washed with water, deydrated, and allowed to stand at least 10hr at room temperature. Hot air at 120 deg.C is blown to the aged dried fish for about 10-15min. so that it is treated with hot air, and it is sent to a shaver to prepare thick flakes of dried fish having the desired thickness.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for producing thick-cut bonito flakes that does not include a steaming process.

Traditionally, shavings are made by steaming bonito flakes or kumibushi to give them a firm texture, soften them appropriately, and then shave them! It was produced over 71FM.

Steaming improves the yield by reducing the generation of powder during the shaving process, increases the product value by giving luster to the shavings, and has a sterilizing effect, but it also prevents the fragrance and extracts contained in the shavings from scattering.・There is a risk of extraction and pollution problems. There is also a known method for producing shaved shibu that uses high-frequency heating without steaming, but although this method can be applied to the production of thin-cut shiobushi, it cannot be applied to the production of thick-cut υ-bushi.

Thinly shaved bonito flakes with a thickness of 0.4 to 0.511IIE reduce the time required to prepare the soup stock, but in general soba restaurants, thicker bonito flakes with a thickness of about 1 inch are preferred, and A It is well known that things need to be boiled for two hours to make the stock.

In addition, in thin shaving, there is a risk that powder formation will increase and the yield will decrease, and in terms of shaving time and bulk, the
Some thickness cutting has been carried out.

It is considered impossible to produce thick-sliced bonito without a steaming process with anything other than grilled bonito flakes, which is not suitable for mass production and is not generally used due to the risk of a burnt odor.

The purpose of the present invention is to eliminate the steaming process in the production of thick-cut bonito flakes, thereby reducing the pollution problems associated with steaming, simplifying the work process, and lowering the manufacturing cost.

The method for producing thick-shaved knots of the present invention is characterized by soaking the knots in water, allowing the moisture to permeate inside, and then treating the knots with hot air and applying them to a shaving machine.

Knots include the female parts of bonito flakes, pigeon bushi, soda bushi, sanma bushi, etc. These joints are first soaked in water while moldy. The immersion time is 1° or less; if it is too long, the extract will leach out, so it is preferable to avoid immersion for too long. Next, remove the knots from the water and wash them.
Allow the water to drain thoroughly (in addition, when using water in winter,
Covering is effective in preventing unexpected excessive drying). Nekashi, which allows moisture to penetrate into the knots, is carried out at room temperature for at least 10 hours, but usually for about 15 hours. The aged knots are then treated with hot air. Usually, a hot air dryer is used to blow hot air at 120° C. for about 10 to 15 minutes. The nodes are arranged so that they do not overlap so that hot air can pass between them.

If the temperature exceeds 120°C, burning may occur, so it is preferable to avoid this. The hot air-treated knots are then passed through a cutting machine to produce thick shaved knots with a desired thickness. A conventional cutting machine was used, and I'll...

When shaved while still hot after hot air treatment, high-quality thick-cut bonito with a gloss and high extract content comparable to those that have gone through the steaming process can be obtained with a good product yield.

The elimination of steps simplifies the process and reduces manufacturing costs. In addition, there is no scattering of extracts and aromas due to steaming, reducing environmental pollution. The method of the present invention makes it possible to produce products with good productivity that do not have a burnt odor like roasted bonito flakes.

Example 1 kg (20 to 25 pieces) of moldy mackerel were immersed in water for 10 minutes, washed, drained, covered, and left to rest for about 15 hours. Next, they were placed in a box dryer (parallel flow type, model 50ES) manufactured by Fuji Paudal Co., Ltd. with some spacing between them, and hot air at 120° C. was blown for 10 minutes. Afterwards, it was put through a shaving machine while it was still hot to produce shavings with a thickness of 1 dragon. product 940
f was obtained, and the resulting powder weighed 66 g.

15 tons of the obtained finely shaved bonito flakes were placed in 400 cc of boiling water, and boiling was continued for 20 minutes to obtain 250 cc of soup stock. The extract concentration obtained was measured with an Atago hand-held refractometer at a room temperature of 29°C and a liquid temperature of 26°C, and the extract concentration was 0.9°C.

Comparative Example: 1 kg of moldy mackerel, similar to that used in Example, was washed with water, steamed for 20 minutes, dried with hot air at 120°C for 10 minutes in the box-type dryer, and shaved into IU-thick mackerel. was manufactured. 932f of product was obtained and the resulting powder was 50f.

When the stock was boiled and the extract content was measured in the same manner as in the example, the extract concentration was 0.8%.

As seen in the above examples, the method for producing thick cut knots of the present invention has a good product yield and a high extract concentration.
