Practices related to increasing understanding of and interest in fair trade activities
Get PDF本研究では、フェアトレード活動への理解及び関心の向上を目指した実践を行い、その効果について検討を行うことを目的とした。香川大学祭のブースでフェアトレード活動への理解及び関心の向上を目指した実践として、来場者全員に対してフェアトレード活動の説明を行った。さらに、フェアトレード活動として雑貨とコーヒー豆の販売を行った。フェアトレードについての説明を聞いた来場者273名に対してアンケート調査を実施した。その結果、多くの人がフェアトレードについて聞いたことがあるが説明できないこと、フェアトレード商品について多くの人が授業や教科書がきっかけで知り、知っているフェアトレード商品の種類はコーヒー・カカオ豆・チョコレートが多いこと、フェアトレード商品の必要性の理解、児童労働・貧困に関する知識、児童労働・貧困への関心、フェアトレード商品への関心、国際協力活動への態度が向上することが明らかとなった。departmental bulletin pape

Social Science Session
Get PDFThe main activities conducted by the Social Science session members’ presentations and poster sessions are summarized below. The session highlighted the interconnectedness and unity of purpose across various research fields. A wide spectrum of research was presented in the sessions focusing on education, the environment, legal issues, and various outreach programmes. Regarding potential future academic, research, and student collaborations among the trilateral partners, one goal is to further expand the existing teacher training programmes for students to teach classes abroad. Another goal is to consider sustainable funding for visiting academics.departmental bulletin pape
Characteristics of whole wheat flour obtained from the durum wheat cultivar “Setodure” grown in Kagawa Prefecture, Japan．
Get PDFSince durum wheat has not been cultivated in Japan, knowledge on its production and processing methods is lacking. In particular, few studies have focused on the use and characteristics of durum wheat whole wheat flour. In this study, whole wheat flour obtained from the durum wheat cultivar ‘Setodure’ grown in three locations in Kagawa Prefecture（Sanuki City, Miki Town, and Shodoshima Town）was processed into scones and clarified the characteristics of its nutritional composition, processing characteristics, and tasting quality. The results of the compositional analysis showed that the whole wheat flour obtained from ‘Setodure’ contained approximately 1.9, 4.1, and 4.5 times more fat, dietary fiber, and ash, respectively, than flour of wheat for bread, but the nutritional composition of ‘Setodure’ was not different from that of the whole wheat flour obtained from wheat for bread. Although the protein content（≒gluten content）of ‘Setodure’ was higher than that of the wheat cultivar for Japanese noodle ‘Sanukinoyume2009’, the height and volume when each whole wheat flour was processed into scones were significantly lower in ‘Setodure’ than in ‘Sanukinoyume2009’. Scones made from whole wheat flour of ‘Setodure’ showed poor puffiness but were not evaluated as bad textures on the taste test. The overall evaluation （1: poor－5: good） was also not significantly lower for the ‘Setodure’ scones（3.2/5.0）than for normal scones（3.0/5.0）or scones made from whole wheat flour of ‘Sanukinoyume2009’（3.4/5.0）.It was considered that the whole wheat flour of ‘Setodure’ has no special characteristics in terms of composition and taste, but it is necessary to pay attention to poor puffiness due to low gluten quality when producing processed products like scones．departmental bulletin pape
Inheritance of glycosylation of the malvidin 5-O-position and its effects on flower color expression in cyclamen with malvidin glycoside as the main flower pigment
Get PDFThe inheritance of glycosylation at the 5-O-position of malvidin and its effects on flower color expression in cyclamen containing malvidin glycoside as the main flower pigment were investigated. All F2 progenies between red-purple flowered ‘Cochineal’ containing malvidin 3-O-glucoside（Mv3G）in the petals as the main pigment and purple flowered ‘Wase-Murasaki’ containing malvidin 3,5-di-O-glucoside（Mv3,5dG）in the petals as the main pigment, and all F2 and BC1 progenies between red-purple flowered ‘Piccolo（red-purple flowered）’containing Mv3G in the petals as the main pigment and purple flowered ‘KN-Purple’ containing Mv3,5dG in the petals as the main pigment separated into the plants containing Mv3,5dG as the main petal pigment and those containing Mv3G in the petals as the main petal pigment. The segregation ratio of the main flower pigment of all F2 and BC1 progenies fitted the expected Mendelian ratio, showing that the glycosylation of the 5-O-position of Mv3G in the petals was controlled by a single dominant gene. The progenies with Mv3,5dG as the main petal pigment tended to have bluer petals than those with Mv3G as the main petal pigment. These results suggested that glycosylation of the 5-O-position of Mv3G was a dominant characteristic in cyclamen and that glycosylation of the 5-O-position of Mv3G increased the blueness of the cyclamen petals.マルビジン配糖体を主要花色素とするシクラメン園芸品種におけるマルビジンの5位の配糖体化の遺伝とその花色への影響を調査した．その結果，Mv3Gを主要花色素とする赤紫色花品種‘コチニール’とMv3,5dGを主要花色素とする紫色花品種‘早生紫’との正逆交雑により得られたF2後代，ならびにMv3Gを主要花色素とする赤紫色花品種‘ピッコロ（RP）’とMv3,5dGを主要花色素とする紫色花品種‘KN パープル’との正逆交雑により得られたF2およびBC1後代のいずれにおいても，Mv3Gを主要花色素とする個体とMv3,5dGを主要花色素とする個体とに分離し，その分離比は顕性の1遺伝子がマルビジンの5位の配糖体化を支配すると仮定した場合の分離比に矛盾しなかった．また，Mv3,5dGを主要花色素とするF2およびBC1個体では，Mv3Gを主要花色素とする個体より花弁の青みが強くなる傾向が認められた．これらのことから，シクラメン花弁において，マルビジンの5位の配糖体化は顕性形質として発現すること，およびマルビジン配糖体を主要アントシアニンとする個体では5位の配糖体化によって花弁の青みが増すことが示唆された．departmental bulletin pape
Survey of aflatoxins contamination of Indonesian cacao products
Get PDFIndonesia is the third largest producer of cocoa beans in the world. Cacao beans are potentially contaminated with aflatoxins, a potent hepatocarcinogenic mycotoxin, but there are few reports on aflatoxins contamination of cacao beans from Indonesia. Therefore, cacao beans and their processed products from Indonesia were collected and investigated for contamination by immunoaffinity column（IAC）-HPLC. Cacao beans（38 samples）from Bali, Java, Sumatra, Sulawesi in Indonesia, and processed cacao products（23 samples of chocolate and cocoa powder）from Indonesian retail stores were collected. Analysis of these cocoa beans revealed that aflatoxins were detected in 33（87%）of the samples. The mean total aflatoxins concentration in all samples was 0.460 μg/kg, with a maximum value of 2.07 μg/kg. AFB1 was detected at the highest concentration in all samples with a mean of 0.221 μg/kg and a maximum value of 1.03 μg/kg. No regional differences in cocoa bean production were observed. Aflatoxins were detected in all 23 processed cocoa bean samples. The mean total aflatoxins concentration in all samples was 0.185±0.09 μg/kg, with a maximum value of 0.44 μg/kg. AFB1 was detected at the highest concentration in all samples with a mean of 0.059±0.07 μg/kg and a maximum value of 0.28 μg/kg. However, none of the samples exceeded the EU（AFB1, 2 μg/kg and total AFs, 4 μg/kg）,which has set the strictest limit values. Although Indonesian cacao beans and commercial chocolate were contaminated with aflatoxin at a high frequency, the concentrations were sufficiently low to be considered not immediately harmful to human health.インドネシアは世界3番目のカカオ豆生産国である．カカオ豆は強力な肝発がん性のマイコトキシンであるアフラトキシン汚染の可能性があるが，インドネシア産のカカオ豆のアフラトキシン汚染に関する報告はほとんどない．そこで，インドネシア産のカカオ豆とその加工品を収集し，イムノアフィニテーカラム（IAC）-HPLC法で汚染調査を行った．インドネシアのバリ，ジャワ，スマトラ，スラウェシ島などからカカオ豆（38 検体）とインドネシアの小売店からカカオ豆加工品（チョコレートとココアパウダーの23検体）を収集した．これらのカカオ豆を分析した結果，33検体（87%）からアフラトキシンが検出された．総アフラトキシンの全検体平均は0.464 μg/kg，最大値は，2.07 μg/kgであり，AFB1は全検体平均は0.221 μg/kg，最大値は1.03 μg/kgで最も高濃度で検出された．カカオ豆生産地域差は認められなかった．カカオ豆加工品では23件全てからアフラトキシンが検出された．総アフラトキシンの全検体平均は0.185±0.09 μg/kg，最大値は0.44 μg/kgであり，AFB1は全検体平均は0.059±0.07 μg/kg，最大値は0.28 μg/kgで最も高濃度で検出された．しかし，最も厳しい規制値を設定しているEU（AFB1，2 μg/kgと総AF，4 μg/kg）を超えている検体はなかった．インドネシア産カカオ豆や市販チョコレートは高頻度でアフラトキシンに汚染されていたが，その濃度は充分に低く，直ちにヒトの健康被害が発生するレベルではないと考えられた．departmental bulletin pape
