さらに、本発明は、西洋カボチャ種子とワタの混合物を直火で燃焼し、灰化したワタを除いて、乾燥した西洋カボチャ種子を搾油することを特徴とする西洋カボチャ種子油の製造方法に関する。
さらに、本発明は、西洋カボチャ種子とワタの混合物を還元状態（低酸素状態）で加熱し、炭化または非炭化のワタを除いて、種皮表面が加熱により変性した西洋カボチャ種子を搾油することを特徴とする西洋カボチャ種子油の製造方法に関する。
The present invention relates to a method for producing western pumpkin seed oil, which comprises heating and drying a mixture of western pumpkin seeds and cotton, excluding cotton, and pressing the western pumpkin seeds whose seed coat surface has been modified by heating.
Furthermore, the present invention relates to a method for producing western pumpkin seed oil, characterized in that a mixture of western pumpkin seeds and cotton is burned in an open flame to remove the ashed cotton and the dried western pumpkin seeds are squeezed.
Further, the present invention is to heat a mixture of western pumpkin seeds and cotton in a reduced state (low oxygen state), and to extract the western pumpkin seeds whose seed coat surface has been denatured by heating, except for carbonized or non-carbonized cotton. It is related with the manufacturing method of the characteristic Western pumpkin seed oil.
カボチャはウリ科の一年草または多年草で、大きく分けて東洋カボチャ(Cucurbita moschata)、西洋カボチャ(Cucurbita maxima)、ペポカボチャ(Cucurbita pepo)の3種類に分けられており、日本で一般に、食用に、又は冷凍食品や調理食品に加工されるのは、主に西洋カボチャである。東洋カボチャは日本カボチャとも言われ、粘質でねっとりした食感を有するが、現在ではほとんど西洋カボチャが栽培され消費されている。ペポカボチャは殻（種皮）のある種子を持つ東洋カボチャや西洋カボチャと大きく異なり、殻のない種子を持つのが大きな特徴であり、日本ではほとんど栽培されていない。小さなものや細長いものや特異な形を有するものもあり、西洋料理で用いられるズッキーニもペポカボチャの一品種であるが、ズッキーニ以外のペポカボチャは食用としてより、装飾用として用いられることが多い。また、海外で食用油（パンプキンシードオイル）として製造されるのはペポカボチャ種子から抽出した油である。本発明では、従来知られているペポカボチャ種子から抽出した油脂をパンプキンシードオイルと呼び、本発明で試みた西洋カボチャ種子から抽出した油脂をカボチャ種子油と呼ぶこととする Pumpkin is an annual or perennial plant of the cucurbitaceae, and is roughly divided into three types: oriental pumpkin (Cucurbita moschata), western pumpkin (Cucurbita maxima), pepo pumpkin (Cucurbita pepo). Or it is mainly a western pumpkin that is processed into frozen food or cooked food. Oriental pumpkins are said to be Japanese pumpkins and have a sticky and sticky texture, but now, Western pumpkins are mostly grown and consumed. Pepo pumpkins are very different from oriental and western pumpkins that have seeds with shells (seed coats). They are characterized by having seeds without shells and are rarely cultivated in Japan. There are small ones, elongated ones, and ones having a peculiar shape, and zucchini used in Western cuisine is a kind of peppo pumpkin, but peppo pumpkins other than zucchini are often used for decoration rather than edible. In addition, it is oil extracted from pepo pumpkin seeds that is produced overseas as edible oil (pumpkin seed oil). In the present invention, fats and oils extracted from conventionally known peppo pumpkin seeds are called pumpkin seed oil, and fats and oils extracted from western pumpkin seeds tried in the present invention are called pumpkin seed oils.
このように、「パンプキンシードオイル」という名称の下に、カボチャの種子油製品が販売されているが、これらはペポカボチャの種子を由来とするものであり、本発明者らが製造方法を見出した現在我国で一般に、食用に、又は冷凍食品や調理食品に加工されている西洋カボチャ(Cucurbita maxima)から採油したものではない。
我国で多く栽培されている西洋カボチャは中央アメリカや南アメリカの高原地帯が原産地で、我国でも原産地の気候を反映して東北地方や北海道が主な産地である。我国の西洋カボチャの栽培面積は、平成１８年度で、１６，９００ｈａ、収穫量２２０，４００ｔである。その内、カボチャとして家庭に流通する生食用に６７％、調理食品などの加工用に３３％が利用されている。加工用に用いられた場合、カボチャのおよそ３分の１が種子とワタとして排出される。
In this way, pumpkin seed oil products are sold under the name “pumpkin seed oil”, which are derived from peppo pumpkin seeds, and the present inventors have found a production method. It is not taken from Western pumpkin (Cucurbita maxima), which is currently processed in Japan, either edible or frozen or cooked.
Western pumpkins that are cultivated in many countries in Japan originate from the plateaus of Central America and South America, and in Japan, the Tohoku region and Hokkaido are the main production regions, reflecting the climate of the country of origin. The cultivation area of Western pumpkins in Japan is 16,900ha and the harvest is 220,400t in FY2006. Among them, 67% is used for raw foods distributed to homes as pumpkins, and 33% is used for processing cooked foods. When used for processing, approximately one third of the pumpkin is discharged as seeds and cotton.
西洋カボチャの加工時に排出される種子やワタは従来、一部が飼料や堆肥として利用されてきたが、生の状態で飼料へ利用しようとするにもワタは腐敗が早く、また、種子の発芽率が高いこと、堆肥としての熟成に時間がかかること、種子を擂り潰してから堆肥にするなどの手間がかかることから農家から敬遠されてきた。それゆえ、現在、西洋カボチャの加工時に排出される種子とワタはその大部分が農産廃棄物として処理されている。本発明で用いられる西洋カボチャ(Cucurbita maxima)種子は、冷凍食品や調理食品などに加工される際の農産廃棄物であり、ワタを含めて全国で年に約２４，０００ｔ排出される。加工時に排出された、カボチャ種子やワタはこれまで家畜の飼料または農地に堆肥として還元されてきたが、加工工場の距離的問題や集中的に排出されるために飼料としての消費が限界に達している。堆肥として利用するにも高い発芽率や完熟に長期間を要するなど堆肥に適しているとは言えなかった。このため、工業的に肥料・飼料化することも試みられたが、破砕・乾燥工程での高コストが課題となり実用化が困難であった。したがって、西洋カボチャ(Cucurbita maxima)種子は、未利用バイオマスであり、農産廃棄物でもある。この未利用バイオマスから食品または医薬品の原料として利用できるカボチャ種子油を生産することにより、資源の有効利用と、廃棄物の軽減という面からも本発明は有用である。 Some of the seeds and cotton discharged during the processing of western pumpkins have been used in the past as feed and compost. However, even if you try to use it in the raw state, the cotton rots quickly and the seed germination It has been shunned by farmers because of its high rate, aging as compost, and the time and effort required for composting seeds. Therefore, most of the seeds and cotton discharged during the processing of western pumpkins are currently treated as agricultural waste. Western pumpkin (Cucurbita maxima) seeds used in the present invention are agricultural waste when processed into frozen foods, cooked foods, etc., and are discharged about 24,000 tons annually including cotton. Pumpkin seeds and cotton discharged during processing have been reduced as compost to livestock feed or farmland so far, but the consumption as feed has reached the limit due to distance problems in the processing plant and intensive discharge. ing. It can not be said that it is suitable for compost because it has a high germination rate and requires a long time for ripeness to be used as compost. For this reason, attempts to industrially make fertilizers and feeds have also been made, but high costs in the crushing and drying processes have become issues, making it difficult to put to practical use. Accordingly, Western pumpkin (Cucurbita maxima) seeds are both unused biomass and agricultural waste. By producing pumpkin seed oil that can be used as a raw material for food or medicine from this unused biomass, the present invention is also useful from the viewpoint of effective use of resources and reduction of waste.
一方、西洋カボチャの乾燥種子には約２０％の油が含まれており、この油は立派な食用油原料である。
我国の西洋カボチャの収穫量２２０，４００tの内、加工用に利用された残りの排出される種子とワタの量は約２４，２００tであり、それから約８，０００tの乾燥種子が得られる。この乾燥種子中には約１、６００tの油が含まれており、食用に供することのできる油脂資源が毎年大量に廃棄されている。
On the other hand, dry seeds of Western pumpkin contain about 20% oil, which is a fine edible oil raw material.
Of the 220,400 tons of Western pumpkins harvested in Japan, the amount of remaining discharged seeds and cotton used for processing is about 24,200 tons, from which about 8,000 tons of dry seeds are obtained. This dry seed contains about 1,600 tons of oil, and a large amount of fat resources that can be used for food is discarded every year.
一方、西洋カボチャ種子油には食用としてその香ばしい風味が好まれることに加えてある種の生理効果を有することが知られている。このように生理活性物質含有の面からも今まで余り知られていなかった西洋カボチャ種子油に対する需要がますます高まっていくことが予想される。このような観点から、現在未利用の西洋カボチャの種子から油を効率的に搾油することが求められる。しかし、西洋カボチャの種子から油を搾ることには、種々の問題があった。 On the other hand, it is known that western pumpkin seed oil has certain physiological effects in addition to its fragrant flavor being preferred for food. As described above, it is expected that the demand for western pumpkin seed oil, which has not been known so far, from the aspect of containing a physiologically active substance will further increase. From such a viewpoint, it is required to efficiently squeeze oil from currently unused western pumpkin seeds. However, there have been various problems in squeezing oil from the seeds of western pumpkin.
通常、菜種などの農産種子から食用油を得るのには、種子をクッカー（摂氏１１５℃の蒸気で加熱されるジャケット式のタンク）で加熱してから、搾油機で油を採取する。
しかしながら、従来、我国で西洋カボチャの種子から油を搾って利用するということが行われてこなかったのは、カボチャの種子と一緒に排出される大量のワタを分離できなかったためである。西洋カボチャのワタは導管でしっかりと種子の表面を覆う種皮に結合しており、種子からワタを除く事が難しい。種子を搾油機にかけて油を得る際、この夾雑するワタが障害となって油を得ることが出来ないのである。即ち、種子から搾られた油は夾雑するワタに吸収されてしまい、分離した油として採取することが出来ない。
Usually, in order to obtain edible oil from agricultural seeds such as rapeseed, the seed is heated by a cooker (a jacket-type tank heated by steam at 115 ° C.), and then the oil is collected by an oil press.
However, the reason why oil has not been squeezed from western pumpkin seeds in Japan has been that the large amount of cotton discharged together with pumpkin seeds could not be separated. Western pumpkin cotton is tightly bound to the seed coat covering the seed surface with a conduit, making it difficult to remove cotton from the seed. When the seeds are put into an oil press to obtain the oil, the contaminated cotton becomes an obstacle and the oil cannot be obtained. That is, oil squeezed from seeds is absorbed by contaminating cotton and cannot be collected as separated oil.
一方、欧州では昔から「パンプキンシードオイル」が存在するが、この原料はペポカボチャである。欧州で昔から「パンプキンシードオイル」を得るために栽培されているペポカボチャ(Cucurbita pepo)は種子の表面を覆う種皮が非常に薄く、子葉が露出している。そのため種子とワタが導管によってとても緩くしか結合しておらず、種子とワタを容易に分離することが出来る。そこで、ワタを除いた種子から搾油機で油を搾って食用に供することが行われている。
したがって、調理食品の製造工程から排出される西洋カボチャの大量の種子やワタの夾雑物から効率的に種子油を搾油することが本発明の課題である。
On the other hand, “Pumpkin Seed Oil” has existed for a long time in Europe. Cucurbita pepo, which has been cultivated for a long time in Europe to obtain “pumpkin seed oil”, has a very thin seed coat covering the surface of the seed and exposed cotyledons. Therefore, the seed and cotton are only very loosely connected by the conduit, and the seed and cotton can be easily separated. Therefore, squeezing oil from a seed excluding cotton with an oil press is used for food.
Accordingly, it is an object of the present invention to efficiently squeeze seed oil from a large amount of Western pumpkin seeds and cotton impurities discharged from the process of producing cooked food.
本発明者らは、西洋カボチャ種子油を効率的に搾油する方法について鋭意研究を行ってきた。
まず、西洋カボチャの加工工場から排出された生の西洋カボチャの種子とワタの混合物を搾油機で搾油したときの搾油量を調べた。
The inventors of the present invention have conducted intensive research on a method for efficiently extracting western pumpkin seed oil.
First, the amount of oil extracted when a mixture of raw Western pumpkin seeds and cotton discharged from a Western pumpkin processing plant was extracted with an oil press.
表1は西洋カボチャの種子とワタを乾燥せずに直接搾油した場合の搾油量を示したものである。表から見られるようにせっかく搾油した油分がワタに吸収されてしまい搾油量はほとんどなかった。これはワタをかなり除去してもほとんど同じ結果であり、ワタの油分吸収量が多量にわたることを物語っている・
西洋カボチャのワタは導管でしっかりと種子の表面を覆う種皮に結合しており、種子からワタを除く事が難しい。種子を搾油機にかけて油を得る際、このワタが障害となって油を得ることが出来ないのである。すなわち、種子から搾られた油は混在するワタに吸収されてしまい、カボチャ種子油として採取することが出来ない。
Table 1 shows the amount of oil extracted when Western pumpkin seeds and cotton are directly compressed without drying. As can be seen from the table, the amount of oil squeezed was absorbed by cotton and there was almost no oil squeezed. This is almost the same result even if the cotton is removed considerably, which shows that the oil absorption amount of cotton is excessive.
Western pumpkin cotton is tightly bound to the seed coat covering the seed surface with a conduit, making it difficult to remove cotton from the seed. When the seeds are put into an oil press to obtain oil, this cotton becomes an obstacle and the oil cannot be obtained. That is, oil squeezed from the seed is absorbed by the mixed cotton and cannot be collected as pumpkin seed oil.
そして、ワタをかなり除去してもほとんど同じ結果であることから、ワタの吸収量が多量に亘るだけではなく種子の種皮にも油分が吸収されてしまうことが判明した。
そこで西洋カボチャの加工時に排出される種子とワタの混在物からワタを除き、搾られた油がワタに吸収されずに得られるような方法、及び種子の種皮にも油分が吸収されずに得られるような方法の２方法について、種々検討した。
And since it is almost the same result even if cotton is removed considerably, it turned out that not only the amount of cotton absorption is large, but also the oil content is absorbed into the seed coat of seeds.
Therefore, by removing cotton from the mixture of seeds and cotton discharged during the processing of western pumpkins, the method is such that the squeezed oil is obtained without being absorbed by the cotton, and the seed coat is obtained without oil being absorbed. Various methods have been studied.
まず、ワタを除く方法として、最も一般的に考えられる方法は水洗である。強力なミキサーで種子とワタの混合物を攪拌した後、金網の篩で種子とワタを分離した。この方法の欠点は大量の水を使用するために、排水処理の負荷が大きく、通常のカボチャ加工工場の排水処理施設では処理しきれない。また、得られた水洗後の種子は大量の水分を含んでおり、このままでは搾油できない。種子を乾燥させ、さらにクッカーなどの加熱機を通した後、搾油機にかける必要がある。 First, the most commonly considered method for removing cotton is washing with water. After stirring the mixture of seeds and cotton with a powerful mixer, the seeds and cotton were separated with a wire mesh sieve. The disadvantage of this method is that a large amount of water is used, so the load of wastewater treatment is large, and the wastewater treatment facility of a normal pumpkin processing factory cannot handle it. Moreover, the seeds obtained after washing with water contain a large amount of water and cannot be squeezed as it is. It is necessary to dry the seed and pass it through a heating machine such as a cooker and then apply it to an oil press.
そこで、西洋カボチャの種子とワタの混在物から、ワタを除き、かつ同時に種皮のコルク様の組織を破壊して、容易に搾油が出来るようにするために、直火で燃焼させる方法を見出した。
即ち、回転する円筒の中を西洋カボチャの種子とワタの混合物を移動させながら、バーナーの直火で焼く事により、ワタは燃焼して灰状となって除かれ、種皮のコルク様の組織は加熱により破壊されて、種子も乾燥して油分の分離が促進され、搾油機で容易に油を搾ることが可能になった。
Therefore, we found a method of burning in a direct fire to remove the cotton from the mixture of Western pumpkin seeds and cotton and at the same time destroy the cork-like tissue of the seed coat so that it can be easily squeezed. .
That is, by moving the mixture of western pumpkin seeds and cotton in a rotating cylinder and baking it with a burner, the cotton burns and is removed as ash, and the cork-like tissue of the seed coat is removed. It was destroyed by heating, and the seeds were also dried to promote oil separation, so that the oil could be easily squeezed with an oil press.
表２は西洋カボチャの種子とワタを乾燥させ、クッカーで加熱した後、搾油した場合の油収量を示したものである。 Table 2 shows the oil yield when Western pumpkin seeds and cotton are dried, heated with a cooker, and then squeezed.
本発明の西洋カボチャ種子油の製造方法は西洋カボチャ種子とワタの混合物から種子を容易に分離することができ、しかも同時に種子を乾燥させるとともに、種皮の多孔質組織を加熱により変性破壊して、搾られた油が種皮に吸収されずに得ることができるので、西洋カボチャ種子油の搾油に有用である。 The method for producing western pumpkin seed oil of the present invention can easily separate seeds from a mixture of western pumpkin seeds and cotton, and at the same time, the seeds are dried and the porous tissue of the seed coat is denatured and destroyed by heating. Since the squeezed oil can be obtained without being absorbed by the seed coat, it is useful for squeezing western pumpkin seed oil.
本発明に係る西洋カボチャ種子油の製造方法は西洋カボチャの種子とワタの混在物から、加熱によりワタを除き、かつ同時に西洋カボチャ種皮のコルク様の組織を破壊して、西洋カボチャ種子油が容易に搾油出来るようにしたものである。
そこで、我々は西洋カボチャの種子とワタの混在物から、ワタを除き、かつ同時に種皮のコルク様の組織を破壊して、容易に搾油が出来るようにするために、直火で燃焼させる方法を見出した。
すなわち、回転する円筒の中を西洋カボチャの種子とワタの混合物を入れて移動させながら、バーナーの直火で焼く事により、ワタは燃焼し灰化して除かれ、種子は乾燥して油分の分離が促進され、種皮のコルク様の組織は加熱により破壊されて、搾油機で搾油した油分が種皮のコルク様の組織に吸収されずに容易に西洋カボチャ種子油を搾ることが可能になった。
The method for producing western pumpkin seed oil according to the present invention facilitates western pumpkin seed oil by removing cotton from a mixture of western pumpkin seeds and cotton by heating and simultaneously destroying the cork-like tissue of the western pumpkin seed coat. The oil can be squeezed.
Therefore, we removed the cotton from the mixture of Western pumpkin seeds and cotton, and at the same time destroyed the cork-like tissue of the seed coat so that it could be easily squeezed and burned with an open flame. I found it.
In other words, a mixture of Western pumpkin seeds and cotton is put in a rotating cylinder and moved, and then burned in a direct burner to burn and remove ash, and the seeds are dried to separate the oil. The cork-like tissue of the seed coat was destroyed by heating, and it became possible to easily squeeze the pumpkin seed oil without the oil extracted by the oil press being absorbed by the cork-like tissue of the seed coat.
バーナーの直火で焼くという一見単純な方法で、搾油した油分を吸着して油分の採取の障害となっていたワタを灰化して除きやすくし、ワタとともに油分の採取の障害となっていた種皮のコルク様の組織も加熱により破壊されて油分の浸透を防ぐことができ、さらにまた種子の乾燥度の上昇により油分が分離しやすくなるという効果を生み出す画期的な方法である。 The seed coat that has become an obstacle to oil collection together with cotton, making it easier to ash and remove the oil that has become an obstacle to oil collection by adsorbing the oil extracted by a seemingly simple method of baking with an open flame of a burner This cork-like tissue can be destroyed by heating to prevent oil permeation, and it is an epoch-making method that produces an effect that oil content is easily separated by increasing the dryness of seeds.
しかしながら、上記の方法はワタを燃焼する際に、ダイオキシンの発生が懸念され、またワタの量が非常に多い場合にワタを完全に灰化することが難しい。
そこで、我々は西洋カボチャの種子とワタの混合物の処理方法を鋭意研究した結果、還元状態、即ち、低酸素の状態で種子とワタの混合物を高温で加熱する事により、ワタは炭化して微細な粒子となって種子から分離させる事が出来た。
これは炭焼き釜の原理と類似するものであり、入り口と出口に開口部があるだけの密閉容器の中を種子とワタの混合物を移動させながら、４００度から６００度の高温にさらすとワタは炭化して種皮からはがれ、かつ微粒子化し、その混合物を水洗もしくは高圧空気処理すると非常に容易に、かつ完全な状態で、種子とワタを分離する事が出来た。
また、種子は高温にさらされた事により種皮のコルク様組織が破壊され、油分の浸透を防ぐことができ搾油が容易となった。
さらにこの方法を用いると、ワタの量が非常に多い場合でもなんら問題なく、容易にワタを炭化、微粒子化して除く事が出来る。
酸素がある状態で、このような高温に種子とワタをさらすと燃焼してしまい、ダイオキシンの発生が起こる。よって、還元状態即ち低酸素状態で高温加熱処理する事により、燃焼を抑えて、かつワタの炭化による種皮からの分離をなさしめることができた。
また、加熱温度と加熱時間を低く短く調整する事により、炭化させずにワタの組織をばらばらにし、ワタと種子を分離する事もできる。この非炭化加熱の場合も、還元状態（低酸素状態）で加熱することが必須である。有酸素状態での高温加熱は燃焼を起こし、ダイオキシンの発生をもたらす。
However, in the above method, when burning cotton, there is a concern about generation of dioxins, and when the amount of cotton is very large, it is difficult to completely ash the cotton.
Therefore, as a result of intensive research on the processing method of the mixture of western pumpkin seeds and cotton, by heating the mixture of seeds and cotton at a high temperature in a reduced state, that is, in a low oxygen state, the cotton is carbonized and becomes fine. Particles could be separated from the seeds.
This is similar to the principle of charcoal pots, and cotton is exposed to high temperatures of 400-600 degrees while moving the mixture of seeds and cotton in a closed container with openings at the entrance and exit. Carbonized and peeled off from the seed coat and turned into fine particles. The mixture was washed with water or treated with high-pressure air to separate seeds and cotton very easily and completely.
In addition, the seed was exposed to high temperature, and the cork-like tissue of the seed coat was destroyed, so that oil penetration could be prevented and oil extraction became easy.
Further, when this method is used, even if the amount of cotton is very large, the cotton can be easily carbonized and finely removed without any problem.
When seed and cotton are exposed to such high temperatures in the presence of oxygen, they will burn and dioxins will be generated. Therefore, by carrying out high temperature heat treatment in a reduced state, that is, in a low oxygen state, combustion was suppressed and separation from the seed coat by carbonization of cotton could be achieved.
In addition, by adjusting the heating temperature and the heating time to be low and short, cotton tissue can be separated without carbonization and cotton and seeds can be separated. Even in this non-carbonized heating, it is essential to heat in a reduced state (low oxygen state). High temperature heating in the aerobic state causes combustion and dioxin generation.
この方法が見出されたことにより、種子とワタの混合物を連続的に安全に２４時間処理する事が出来、さらにバーナーによる燃焼に比べ熱効率が大幅に向上し、生産性とコストダウンに大きく貢献する。
また還元状態（低酸素状態）で加熱するのでダイオキシンの発生もほとんどなく廃棄物焼却による環境汚染がない。
なお、加熱の方法としては、工業用の電子レンジや、過熱蒸気を用いることもできるが、これらの装置は設備投資額が大きく、カボチャの加工工場に設置するのはコスト上不利である。
以上の方法を用いて精製した西洋カボチャ種子油は、緑黄色の透明な液状を呈し、西洋カボチャ種子油特有の香ばしい風味を有していた。そのままで、あるいは他の原料と配合して飲食品として利用できる。
以下に、実施例を示し、本発明についてより詳細に説明するが、これらは単に例示するのみであり、本発明はこれらによって何ら限定されるものではない。
With the discovery of this method, the seed and cotton mixture can be continuously and safely treated for 24 hours, and the thermal efficiency is greatly improved compared to combustion with a burner, greatly contributing to productivity and cost reduction. To do.
Moreover, since heating is performed in a reduced state (low oxygen state), there is almost no generation of dioxins and there is no environmental pollution due to waste incineration.
As a heating method, an industrial microwave oven or superheated steam can be used. However, these devices have a large capital investment, and it is disadvantageous in cost to install them in a pumpkin processing factory.
The western pumpkin seed oil refined using the above method had a green-yellow transparent liquid and had a fragrant flavor peculiar to western pumpkin seed oil. It can be used as a food or drink as it is or with other raw materials.
Hereinafter, the present invention will be described in more detail with reference to examples. However, these are merely illustrative, and the present invention is not limited thereto.

(Production of Western Pumpkin Seed Oil in Reduced State-2)
A mixture of 2t of raw pumpkin seeds and cotton 1: 4 was heated using a reduction drying carbonizer (Yakubei D type; manufactured by Sankei Seisakusho Co., Ltd.) while continuously moving in the furnace with a screw conveyor. . The furnace temperature was 400 degrees and heated for about 70 minutes. After the heat treatment, the mixture of seeds and cotton that had been made into non-carbonized fine particles by high-pressure air was removed. The seeds were dried with an air dryer and then squeezed using a pressing machine V-05 manufactured by Suehiro EPM to obtain 19 kg of oil. The oil was allowed to stand, and the supernatant was filtered to obtain a greenish yellow transparent western pumpkin seed oil.
本発明の製造方法により、西洋カボチャの加工時に排出される種子とワタの混在物からワタを除き、かつ種皮の多孔質を破壊して、搾られた油分がワタや種皮に吸収されずに得られるようになり、今まで農産廃棄物として処理されていた西洋カボチャの種子から容易に西洋カボチャ種子油を得ることが出来るようになった。 By the production method of the present invention, cotton is removed from the mixture of seeds and cotton discharged during processing of the Western pumpkin, and the porosity of the seed coat is destroyed, so that the squeezed oil is obtained without being absorbed by the cotton or seed coat. Western pumpkin seed oil can be easily obtained from the seeds of western pumpkins that have been treated as agricultural waste.
