Description

  The present invention relates to a health food of onion shell powder suitable for efficiently extracting active ingredients such as polyphenols, which are said to be useful for maintaining human health, into water.

  The recent restaurant industry has become a chain store, and food raw materials are intensively pre-processed at the factory, so there is a tendency for food waste to be collected by type at that factory. Some of these food scraps are used as livestock feed or compost raw materials, and many are incinerated and not used effectively. Among the foods, onions are peeled off at the factory and delivered to the cooking department of each store. The actual situation is that the skin is discarded together with other food waste at the factory.

  On the other hand, onion is said to contain active ingredients that maintain human health and prevent and improve adult diseases such as hypertension, hyperglycemia, and hyperlipidemia. In order to obtain this effect, health foods made from onion are also on sale. For example, Patent Document 1 discloses a method for producing a health supplement obtained by powdering an onion. After mixing onion and water, crushing and crushing, removing water with a squeezer and drying, a health supplement is obtained.

Moreover, since the powder particle size is 30 to 150 μm, the active ingredient is rapidly and sufficiently extracted into water. When the powder particle size is 150 μm or more, it takes too much time to extract the active ingredient, and the amount of the active ingredient extracted becomes insufficient. If the particle size of the powder is 30 μm or less, the powder will be clumped in water (ie, in an untreated state), and the active ingredient cannot be sufficiently extracted. When it is 30 μm or less, the bitterness becomes stronger when it is dissolved in water and it becomes difficult to drink.

  The invention according to claim 2 is the health food for moisture extraction according to claim 1, wherein the outermost thin skin and the second skin of the onion are colored portions of the onion.

  According to the invention of claim 2, the outermost thin skin and the second outer skin, which are rich in active ingredients in onions, use a colored portion such as brown, which is particularly rich in active ingredients. High efficacy is obtained.

  The invention described in claim 3 is a health food ingestion method characterized by ingesting suspended water in which 0.3 to 0.7 g of the powder according to claim 1 or 2 is mixed in 100 cc of water.

  Since this health food ingests the powder as suspension water, it can ingest all active ingredients such as quercetin contained in the powder. This amount of onion powder in suspension water is easy to drink.

  The invention according to claim 4 is the health food intake method according to claim 3, wherein the water is 60 ° C. to boiling water.

  When the water is 60 ° C. to boiling water, a large amount of active ingredients such as quercetin is dissolved in water and is easily absorbed by the body.

  The invention according to claim 5 is characterized in that the suspended water is ingested in several times a day so that the total intake of powder is 2 to 7 g per day. Ingestion method.

  This health food preferably has a daily intake of about 2 to 7 g, more preferably 3 to 5 g. If it is less than this, the effect is extremely attenuated, and it has not been confirmed that even if it is ingested in excess of this, such a high efficacy can be obtained.

  The invention according to claim 6 includes a step of flowing a dried product obtained by washing and drying the outer skin of an onion on a hot air stream, and applying a shock wave to the dried product in flow to obtain a powder. It is a manufacturing method of the health food of Claim 1 characterized by the above-mentioned.

  Since this production method does not have a step of removing moisture, the active ingredient is not impaired, and a health food containing abundant active ingredients can be produced.

  The invention according to claim 7 is the method for producing a health food according to claim 1, wherein the dried product washed with water and dried as described above shuts off moisture and ends the step.

  According to the manufacturing method of claim 7, since the raw onion skin is washed and dried in an unprocessed state, the moisture is blocked and the desired powdered health food is produced, so that the active ingredient does not flow out.

  Since the onion skin powder health food for moisture extraction of the present invention does not use moisture during the production process, the contained active ingredient is not impaired. Onion is effective for maintaining the health of humans, such as quercetin with antioxidative properties, polyphenols such as quercetin glycosides, allicin with hypoglycemic activity, sulfur-containing organic compounds, and fructo-oligosaccharides that grow intestinal bifidobacteria. Rich in ingredients. In particular, the outer skin is rich in quercetin. The health food of the present invention can be consumed by the human body without waste. Efficacy such as prevention and improvement of adult diseases such as hypertension, hyperglycemia and hyperlipidemia can be obtained. In addition, since the onion shell that would otherwise be thrown away as waste is used, it will also be an effective use of resources.

  The onion skin powder health food for moisture extraction of the present invention is produced as follows.

  The onion harvested from the field is washed with water, peeled, and the core is shipped as food. The dried and stored skin is collected from its outermost thin skin (brown skin), placed in a coarse net bag and sprayed with compressed air to remove dust. When the onion skin thus cleaned is pulverized to a mean particle size of about 100 μm by jetting pressure air using a jet drying type pressure air jet device (manufactured by Yamaura Co., Ltd.), The onion hull powder health food for water extraction is obtained.

  Take this onion husk powder health food for water extraction, put a full bowl of tea (approx. 0.5-0.7 g) in hot water of a cup of hot water (approx. 120-150 cc), stir until there is no lumps and drink.
