Problems solved by technology

[0005] The odorless processing method of the invention described in Japanese Patent Application Laid-Open No. 6-311857, by putting garlic heads into a steamer, steaming them at 120°C for about 2 minutes under a pressurized condition of 1 atmosphere to make the garlic which is the source of the unpleasant smell Disulfide is gasified and released, so that the garlic becomes odorless after treatment, but because the components with bactericidal effect are inactivated, the garlic is easy to rot
[0006] In addition, sodium hypochlorite is used as a food sterilizer and preservative, but since it is used after washing vegetables, it is not known as an ideal substance suitable for sterilizing the attached miscellaneous bacteria
[0007] The invention described in Japanese Patent Application Laid-Open No. 6-311857 ​​deodorizes the peculiar unpleasant smell of raw garlic, but the components with bactericidal effect are inactivated by heating at 120°C under 1 atmosphere, so if the garlic is kept indoors, It will attach to the miscellaneous bacteria in the air, and the overlapping parts of the garlic will contain moisture in the air, resulting in the reproduction of miscellaneous bacteria
[0008] Other methods of deodorizing garlic also chemically decompose the bactericidal components that are the source of the odor components, so the deterioration of the bactericidal effect cannot be eliminated, and spoilage bacteria in the air adhere to and multiply on the garlic. cause garlic to rot
[0009] In addition, there are a lot of spoilage bacteria living in the soil. Even if the vegetables are harvested and washed, and the surface of the vegetables is dried, the spoilage bacteria will remain attached, and the spoilage bacteria will multiply in the contact parts of the vegetables due to stacking, etc., causing the vegetables to rot.
[0010] It has been pointed out in the literature that for foods that use common sodium hypochlorite as a food bactericide, there are problems such as discoloration due to heating, or deterioration of taste, and excessive salt content.

Embodiment 1

[0036] Here, the vegetable was chosen garlic. After buying raw garlic from Akita prefecture and selling it on the market, if it is left as it is, the surface of the garlic is usually 10 3 The spoilage bacteria adhered to about 1 / g immediately multiplies, and usually rots inside.

[0037] As the anticorrosion treatment process of the present invention, three kinds of aqueous solutions of 0.1% by weight lactic acid aqueous solution, 1% by weight lactic acid aqueous solution and 0.1% by weight lactic acid+0.1% by weight sodium bicarbonate (sodium bicarbonate) aqueous solution were prepared, for each 10 kg of each aqueous solution, 5 kg of raw garlic were respectively immersed therein.

[0038] The temperature of the immersion liquid was 25 degreeC, and the immersion process was performed for 15 minutes. In the present invention, it is preferable that the temperature of the immersion liquid is in the range of 20° C. to 35° C., and the immersion time is in the range of 10 minutes...

Embodiment 2

[0048] Prepare the same dipping solution as above, and dip each 5 kg of onions, carrots, taro, kidney bean pods (sheath ingen beans), komatsuna, broccoli, and shiitake mushrooms into 10 kg of each aqueous solution.

[0049] The temperature of the immersion solution was set at 25° C., and the immersion treatment was performed for 15 minutes.

[0050] The temperature of this immersion liquid is made into the range of 20 degreeC - 35 degreeC, and the immersion time is made into the range of 10 minutes - 20 minutes. However, for komatsuna, bean pods, broccoli, and shiitake mushrooms, the temperature of the dipping solution is below 30°C.

[0051] After the immersion treatment, samples were taken out from each immersion liquid, and dehydration treatment was performed for 5 minutes with a centrifugal separator.

[0052] Thereafter, the anticorrosion-treated sample was dried in a drying room kept at room temperature at 30° C., and dried by blowing air at room temperature until the sur...

Embodiment 3

[0055] A test was conducted on garlic that had been deodorized according to the deodorization treatment described in JP-A-6-311857.

[0056] The odorless garlic treatment of the samples generally went through the following procedures.

[0057] Water was put into the autoclave to boil the water, raw garlic was put therein and covered, and steaming was performed for 2 minutes after confirming that the temperature reached 120° C. at 1 atmosphere. The garlic is taken out from the autoclave, and dried by blasting at a low temperature below 35°C. This is not so much the deodorization of garlic, but rather steaming the garlic, and the processed garlic does not have a bad smell or a sharp taste even if you eat it.

[0058] The known deodorized garlic has decomposed components having a bactericidal effect contained in the garlic, so the bactericidal ability is reduced, and if it is stored or left as it is, a large amount of spoilage bacteria will adhere. When the moisture and tempera...

Abstract

The invention provides a vegetable antiseptic treatment method for cleaning microorganism on surfaces of vegetables. The vegetables are dipped in a lactic acid aqueous solution of 0.1 weight % to 1.0 weight% and are performed cryodrying after the treatment to restrain the reproduction of putrefying bacteria.

Description

technical field [0001] The present invention relates to a method of antiseptic treatment of vegetables, and in particular to a method of antiseptic treatment of vegetables for the purpose of obtaining vegetables which are hard to rot even if they are stored for a long period of time and which have few bacteria attached to them when eaten. Background technique [0002] In the past, it was considered that garlic does not rot because it contains bactericidal ingredients, but no literature related to the antiseptic treatment technology of garlic can be found. In addition, ordinary vegetables are not sterilized before shipment. [0003] Generally, the bad-smelling component of so-called raw garlic is a substance in which allyl sulfide is decomposed by the action of alkali, becomes disulfide or sulfur dioxide, and is gasified. [0004] As a processing method for deodorizing garlic, the processing method described in Japanese Patent Application Laid-Open Publication No. Hei 6-3118...
