Description

本発明は、オリゴ糖および発酵乳製品を有効成分として含有するミネラル吸収改善剤、およびミネラル吸収改善方法に関する。   The present invention relates to a mineral absorption improving agent containing an oligosaccharide and a fermented milk product as active ingredients, and a mineral absorption improving method.

現在、日本において、ミネラルの摂取量が推定平均必要量に達していない人の割合は、非常に多い。特に亜鉛の摂取量は、日本人の30〜40%が推定平均必要量に達していないと推定されている(非特許文献1)。また、近年、日本において潜在的な亜鉛欠乏症患者が非常に多いことが指摘され、亜鉛の栄養状態の改善が重要視されはじめている(非特許文献2)。亜鉛の欠乏症としては、発育遅延・異常、性機能不全、貧血、免疫不全、皮膚障害、下痢、創傷治癒遅延、褥瘡発症・治癒遅延、食欲不振・減退、味覚障害、舌痛、耐糖能低下などが知られている(非特許文献2)。亜鉛欠乏症の予防および改善には、亜鉛摂取量を増大させること、および、亜鉛の吸収率を増大させることが重要であると考えられる。一方で、多量の亜鉛の摂取は、銅などの微量元素の利用性を阻害することが知られている(非特許文献3)。そのため、亜鉛の栄養状態を改善するためには、亜鉛の吸収率を増大させることが、より望ましいと考えられる。   Currently, in Japan, the percentage of people whose mineral intake has not reached the estimated average requirement is very high. In particular, it is estimated that the intake of zinc does not reach the estimated average required amount of 30-40% of Japanese (Non-patent Document 1). In recent years, it has been pointed out that there are a large number of potential zinc deficiency patients in Japan, and improvement in the nutritional status of zinc has begun to be emphasized (Non-Patent Document 2). Zinc deficiency includes growth retardation / abnormality, sexual dysfunction, anemia, immune deficiency, skin disorders, diarrhea, delayed wound healing, pressure ulcer onset / healing delay, loss of appetite / decrease, taste disorder, tongue pain, impaired glucose tolerance, etc. Is known (Non-Patent Document 2). To prevent and ameliorate zinc deficiency, increasing zinc intake and increasing zinc absorption are considered important. On the other hand, it is known that intake of a large amount of zinc inhibits the availability of trace elements such as copper (Non-patent Document 3). Therefore, in order to improve the nutritional state of zinc, it is considered more desirable to increase the zinc absorption rate.

フラクトオリゴ糖、イヌリン、ガラクトオリゴ糖等の難消化性糖類はミネラルの吸収率を増大させることが知られている(特許文献1〜6、非特許文献4)。例えば、ガラクトオリゴ糖は胃の切除の手術後のミネラル補給に有用であることが知られている(特許文献3)。
亜鉛吸収改善物質を用いて亜鉛の吸収率を増大させるという報告も、数が少ないものの、存在する。例えば、難消化性糖類であるフラクトオリゴ糖(非特許文献5)、フラクトオリゴ糖およびイヌリンの混合物(非特許文献6)、イヌリン(非特許文献7)の各々は亜鉛の吸収率を増大させることが報告されている。しかし、これらの亜鉛吸収改善物質の投与量は、カルシウムなどの吸収率を改善する場合のミネラル吸収改善物質の投与量に比べて大きく、食品組成物などの摂取媒体の飼料中の含有率でそれぞれ10質量%、10質量%、7.5質量%である。それより少ない投与量では、亜鉛の吸収に影響を及ぼさないことが報告されている(非特許文献8)。また、ガラクトオリゴ糖に関しては、亜鉛の吸収を増大させるという報告はない。オリゴ糖等の難消化性糖類は、投与量の増大に伴い、下痢等の胃腸症状の発生率が増大する(非特許文献9、10)。そのため、より少ない投与量で亜鉛などのミネラルの吸収促進効果を発揮することが望ましいと考えられる。
なお、フラクトオリゴ糖は強酸性下で加水分解されること(非特許文献11)、および、ガラクトオリゴ糖は酸性条件下や加熱条件下において分解等による減衰を生じにくい性質を有すること(非特許文献12)が報告されている。
ミネラルの吸収に影響を与える因子としては、そのミネラル自体の摂取量・溶解性、他のミネラル、ビタミン、タンパク質等の栄養因子などが挙げられることが報告されている(非特許文献13および非特許文献14)。
It is known that indigestible saccharides such as fructooligosaccharide, inulin and galactooligosaccharide increase the absorption rate of minerals (Patent Documents 1 to 6, Non-Patent Document 4). For example, galactooligosaccharides are known to be useful for mineral supplementation after surgery for gastrectomy (Patent Document 3).
There are reports of increasing the absorption rate of zinc using a substance that improves zinc absorption, although there are few reports. For example, it has been reported that fructooligosaccharides (Non-patent Document 5), a mixture of fructooligosaccharides and inulin (Non-Patent Document 6), and inulin (Non-Patent Document 7), which are indigestible saccharides, increase the absorption rate of zinc. Has been. However, the dosage of these zinc absorption improving substances is larger than the dosage of mineral absorption improving substances in the case of improving the absorption rate of calcium, etc. They are 10 mass%, 10 mass%, and 7.5 mass%. It has been reported that doses smaller than that do not affect the absorption of zinc (Non-patent Document 8). Moreover, there is no report about increasing zinc absorption regarding galactooligosaccharide. Indigestible saccharides such as oligosaccharides increase the incidence of gastrointestinal symptoms such as diarrhea with increasing dose (Non-Patent Documents 9 and 10). Therefore, it is considered desirable to exhibit the effect of promoting the absorption of minerals such as zinc with a smaller dose.
In addition, fructooligosaccharides are hydrolyzed under strong acidity (Non-patent Document 11), and galactooligosaccharides have the property of hardly causing decay due to degradation under acidic conditions or heating conditions (Non-Patent Document 12). ) Has been reported.
It has been reported that factors affecting the absorption of minerals include intake / solubility of the mineral itself, nutritional factors such as other minerals, vitamins, proteins, and the like (Non-Patent Document 13 and Non-Patent Documents). Reference 14).

摂取したミネラルの吸収経路としては、経細胞経路(transcellular pathway)と、細胞間隙経路(paracellular pathway)が知られている。例えば亜鉛の場合、吸収は主に十二指腸と空腸にて行われる。小腸管腔内の亜鉛が低濃度の条件下では、経細胞経路(transcellular
pathway)の吸収活性が増大する。小腸管腔内の亜鉛が高濃度の条件下では、細胞間隙経路(paracellular pathway)の寄与が大きいと言われている。また、亜鉛は回腸や結腸でも吸収されることが示唆されている(長田昌士、亜鉛−生物学的意義、必須性、そして食品における応用、化学と生物、46、pp.629-635(2008)、および、Cousins
RJ, 35:亜鉛 in 専門領域の最新情報 最新栄養学 第9版、翻訳監修:木村修一&小林修平、建帛社、pp.443-455(2007))。本発明のミネラル吸収改善剤は前述の各種機構に限定されず、ミネラルの吸収を高める作用を有する。
Known absorption pathways for minerals ingested include the transcellular pathway and the paracellular pathway. For example, in the case of zinc, absorption is mainly performed in the duodenum and jejunum. Under conditions where zinc in the small intestinal lumen is low, the transcellular pathway (transcellular
pathway) absorption activity increases. Under the condition that zinc in the small intestinal lumen is at a high concentration, it is said that the contribution of the paracellular pathway is large. Zinc is also suggested to be absorbed in the ileum and colon (Masashi Nagata, Zinc-Biological Significance, Essentiality, and Application in Food, Chemistry and Biology, 46, pp.629-635 (2008) And Cousins
RJ, 35: Zinc in the latest information on specialized fields Latest nutrition science 9th edition, translation supervision: Shuichi Kimura & Shuhei Kobayashi, Kenshisha, pp.443-455 (2007)). The mineral absorption improving agent of the present invention is not limited to the various mechanisms described above, and has an effect of increasing mineral absorption.

本発明のミネラル吸収改善剤は、発酵乳製品とオリゴ糖を組み合わせることによって、これら2種の物質の相乗効果を発揮するものであり、従来より亜鉛の吸収を促進することが報告されている難消化性糖類(オリゴ糖など)の投与量よりも少ない量(固形分全量中の含有率)で、亜鉛の吸収を促進することが可能である。そのため、多量の難消化性糖類の摂取に伴う下痢等の胃腸症状の発生の可能性が低い。また、過剰量の亜鉛の摂取によって銅等の他のミネラルの吸収を阻害する可能性も低い。   The mineral absorption improving agent of the present invention exhibits a synergistic effect of these two substances by combining a fermented milk product and an oligosaccharide, and has been reported to promote zinc absorption conventionally. Zinc absorption can be promoted with an amount smaller than the dose of digestible saccharide (such as oligosaccharide) (content in the total solid content). Therefore, the possibility of occurrence of gastrointestinal symptoms such as diarrhea accompanying intake of a large amount of indigestible saccharides is low. In addition, the intake of excessive amounts of zinc is unlikely to inhibit the absorption of other minerals such as copper.

[実施例1](発酵乳製品およびオリゴ糖の給与が亜鉛吸収に及ぼす作用)
本実施例は、発酵乳製品およびガラクトオリゴ糖(以下GOSともいう)の給与が、亜鉛吸収に及ぼす影響を検証した。
[Example 1] (Effect of feeding fermented milk products and oligosaccharides on zinc absorption)
In this example, the effects of feeding fermented milk products and galactooligosaccharide (hereinafter also referred to as GOS) on zinc absorption were examined.

(発酵乳製品の調製)
常法に従って、非熟成チーズを製造した。具体的には、脱脂粉乳を殺菌後、Lactobacillus属に属する乳酸菌およびStreptococcus属に属する乳酸菌で発酵し、さらにレンネットを加えた。さらに、形成されたカードを切断し、遠心分離処理をして得た沈殿物(非熟成チーズ)を発酵乳製品として試験に供した。
(Preparation of fermented dairy products)
Non-aged cheese was produced according to a conventional method. Specifically, skim milk powder was sterilized, then fermented with lactic acid bacteria belonging to the genus Lactobacillus and lactic acid bacteria belonging to the genus Streptococcus, and rennet was further added. Furthermore, the formed card | curd was cut | disconnected and the precipitate (non-aged cheese) obtained by carrying out the centrifugation process was used for the test as fermented milk products.

(動物実験方法)
3週齢の雄性SDラット56匹を平均体重が均一(約47g)になるように、以下の5群(n=8)に分けた。
(a)健常+カゼイン飼料給与群 [対照群]
(b)胃酸低下+カゼイン飼料給与群 [カゼイン群]
(c)胃酸低下+5.0質量%GOS配合カゼイン飼料給与群 [カゼインG群]
(d)胃酸低下+発酵乳製品飼料給与群 [発酵乳製品群]
(e)胃酸低下+5.0質量%GOS配合発酵乳製品飼料給与群[発酵乳製品G群]
(a)〜(e)の各群に、各試験飼料を9日間(day1〜9)、自由摂取にて給与した。なお、カゼイン飼料は通常のAIN-93Gを一部改変して調製した飼料である。発酵乳製品飼料は、タンパク質含量がカゼイン飼料と同等になるように発酵乳製品をカゼインの代わりに配合した飼料である(表1)。また5.0質量%GOS配合飼料は飼料100質量%中にGOSを5.0質量%になるよう配合した飼料である(表1)。なお、全ての飼料においてカルシウム、リン、マグネシウム、鉄、亜鉛、銅含量は同等になるよう調整している(表1)。
(Animal experiment method)
56 male SD rats of 3 weeks old were divided into the following 5 groups (n = 8) so that the average body weight was uniform (about 47 g).
(A) Healthy + casein feed group [control group]
(B) Gastric acid lowering + casein feed group [casein group]
(C) Gastric acid decrease + 5.0 mass% GOS casein feed group [Casein G group]
(D) Gastric acid lowering + fermented dairy feed group [fermented dairy group]
(E) Gastric acid lowering + 5.0 mass% GOS-containing fermented dairy feed group [fermented dairy group G]
Each test feed was fed to each group of (a) to (e) for 9 days (day 1 to 9) by free intake. The casein feed is a feed prepared by partially modifying ordinary AIN-93G. Fermented dairy feed is a feed in which fermented dairy products are blended in place of casein so that the protein content is equivalent to that of casein feed (Table 1). The 5.0% by mass GOS-mixed feed is a feed in which GOS is mixed to 5.0% by mass in 100% by mass of the feed (Table 1). In all feeds, the calcium, phosphorus, magnesium, iron, zinc, and copper contents are adjusted to be equivalent (Table 1).

胃酸低下群(前記(b)〜(e))には、試験開始5日目から試験終了まで(day5〜9)毎日7:00、19:00の2回、プロトンポンプインヒビター(PPI、胃酸分泌抑制剤)であるオメプラール(以下OMともいう、オメプラゾールナトリウム注射剤、アストラゼネカ株式会社製)を皮下に20mg/kg
body weight(OM濃度:4mg/ml、投与容量:5ml/kg body weight)投与して持続的に胃酸分泌を低下させた。健常群(前記(a))にはOMの溶媒として使用する生理食塩水5ml/kg
body weightを、胃酸低下群のPPI投与と同様のスケジュールで皮下投与した。PPI投与開始の翌日(day6)から4日間(day6〜9)、代謝ケージを用いて出納試験を行い、全てのラットの全糞を個体毎に回収した。採取した糞は亜鉛の排泄量の測定に用いた。また、PPI投与開始の翌日(day6)から4日間(day6〜9)の摂餌量を個体毎に測定した。4日間の摂餌量から、亜鉛摂取量を算出し、以下の式で個体毎の亜鉛の見かけの吸収率(質量%)を算出した。
亜鉛の見かけの吸収率(%)=(亜鉛摂取量−糞中亜鉛排泄量)×100/(亜鉛摂取量)
なお、全ての試験期間を通じて、ラットにはイオン交換水を自由摂取させた。また、一日当たりの平均摂餌量は約114g/kg body weight、試験開始初期(day2)の平均体重は57g、試験終了時(day9)の平均体重は110gであった。各群間で、摂餌量、体重の差異は観察されなかった。
In the gastric acid-lowering group (above (b) to (e)), from the 5th day to the end of the test (day 5-9), 7:00 and 19:00 twice a day, proton pump inhibitor (PPI, gastric acid secretion) 20 mg / kg subcutaneously of omepral (hereinafter also referred to as OM, omeprazole sodium injection, manufactured by AstraZeneca)
Administration of body weight (OM concentration: 4 mg / ml, administration volume: 5 ml / kg body weight) continuously reduced gastric acid secretion. For healthy group (above (a)), physiological saline 5ml / kg used as OM solvent
Body weight was administered subcutaneously on the same schedule as PPI administration in the gastric acid lowering group. The next day (day 6) from the start of PPI administration (day 6 to 9), a balance test was conducted using a metabolic cage, and all feces of all rats were collected for each individual. The collected feces was used for measuring the amount of zinc excreted. In addition, food intake was measured for each individual for 4 days (day 6 to 9) from the day after the start of PPI administration (day 6). The amount of zinc intake was calculated from the amount of food consumed for 4 days, and the apparent absorption rate (mass%) of zinc for each individual was calculated using the following formula.
Apparent absorption rate of zinc (%) = (Zinc intake-Fecal zinc excretion) x 100 / (Zinc intake)
Rats were allowed to freely take ion-exchanged water throughout the test period. The average daily food intake was about 114 g / kg body weight, the average body weight at the beginning of the test (day 2) was 57 g, and the average body weight at the end of the test (day 9) was 110 g. No difference in food intake or body weight was observed between the groups.

なお、AIN-93GミネラルミックスおよびAIN-93ビタミンミックスは、米国国立栄養研究所(AIN)から1993年に発表されたマウスやラットにおける栄養研究用の標準精製飼料であり、成長期、妊娠期、授乳期のために用いられるAIN-93Gに配合されているビタミンミックスおよびミネラルミックスを指す。   AIN-93G mineral mix and AIN-93 vitamin mix are standard purified diets for nutritional research in mice and rats published in 1993 by the National Institute of Nutrition (AIN). It refers to vitamin mix and mineral mix blended with AIN-93G used for lactation.

(結果)
(a)対照群と(b)カゼイン群間の見かけの亜鉛吸収率は同等であった。この結果から、PPI投与による胃酸分泌低下は、見かけの亜鉛吸収率にほとんど影響を与えないと考えられた(図1)。また、(e)発酵乳製品G群の見かけの亜鉛吸収率は、他の群と比較して有意に(p<0.05、Tukey-Kramer多重検定)高い値を示したのに対し、(c)カゼインG群は、(b)カゼイン群、および(d)発酵乳製品群と比較して有意な差を認めなかった。この結果から、GOSを含有した飼料を給与しても、単独で亜鉛吸収促進作用はないものの、発酵乳製品と同時に給与することで亜鉛の吸収を相乗的に促進することが明らかとなった(図1)。
なお、図1中、棒グラフの上方の文字a、bは、異なる文字間に有意差があることを示す(p<0.05、Tukey-Kramer多重検定)。また、図1中の「w/w%」は、質量%を意味する。
(result)
The apparent zinc absorption rate between (a) control group and (b) casein group was similar. From this result, it was considered that the decrease in gastric acid secretion by administration of PPI had little effect on the apparent zinc absorption rate (FIG. 1). In addition, the apparent zinc absorption rate of (e) fermented dairy group G was significantly higher (p <0.05, Tukey-Kramer multiple test) compared to other groups, whereas (c) Casein G group showed no significant difference compared to (b) casein group and (d) fermented dairy group. From this result, it was clarified that feeding the feed containing GOS alone does not promote zinc absorption, but synergistically promotes zinc absorption by feeding together with fermented milk products ( FIG. 1).
In FIG. 1, letters a and b above the bar graph indicate that there is a significant difference between different letters (p <0.05, Tukey-Kramer multiple test). Further, “w / w%” in FIG. 1 means mass%.
