Mulberries were obtained from five cultivars, i. e., three cultivars for fruit (Ficus, Kataneo, Raraberi) and two cultivars for sericulture (Ichinose, Tagowase).   The anthocyanins, protein, liquid, sugar and minerals in these mulberries were then analyzed.   In addition, mulberries of the five cultivars were processed into jam to determine and compare the residual quantities of the total anthocyanins and the main anthocyanins. 1) The moisture content of the five mulberry cultivars did not significantly differ. However, the carbohydrate contents of the mulberries cultivars for sericulture were higher than those of the cultivars fruit. 2) The main anthocyanins were determined to be cyanidin 3-glucoside and cyanidin 3-rutinoside in all from five cultivars. The cyanidin 3-rutinoside content ranged from 68-78%. 3) The fruit and jam of the three cultivars for fruit contained larger quantities of the total anthocyanins than those of the cultivars for sericulture. 4) The mulberry jam made from the cultivars for fruit retained higher ratios of the total anthocyanins and the main anthocyanins than the mulberry jam made from the cultivars for sericulture. The anthocyanins in the jam made from the cultivars for fruit were more stable than those in the jam made from the cultivars for sericulture.

【目的】アントシアニン含有馬鈴しょ(有色馬鈴しょ)は, 色素に多くの有用な機能性が見出されているが, 調理の際に容易に分解し, 退色や変色をしてしまう。有色馬鈴しょを用いた調理後の色調は, 油調理では, 比較的色を保つことができるが, 水を介した調理で不安定となりやすい。そこで,有色馬鈴しょに対する水煮調理に用いる水の硬度差が, 有色馬鈴しょの色調にどのように影響するのか検討を行った。【方法】試料はキタムラサキ(KM), ノーザンルビー(NR), シャドークイーン(SQ)を用いた。5倍容の硫酸カルシウム(Ca)と硫酸マグネシウム(Mg)の混合溶液(Ca:Mgの重量比=2:1), およびそれぞれの単体溶液の各溶液に馬鈴しょ塊茎を4mm厚にスライスして投入, 加熱し, クリープメーターを用い加熱後の切片の最大荷重を測定した。また, 水煮処理後の切片の色調を色差計で測定し, L*, a*, b*値に示した。その後, 3%ギ酸を用いて切片より色素を抽出し, 抽出液の吸光度を測定し, アントシアニン残存率を比較した。【結果】水煮調理後の有色馬鈴しょ切片の最大荷重は, 3品種ともMg単体溶液ではいずれの硬度においても, Ca-Mg混合溶液の硬度0から硬度50と近似値を示した。一方でCa単体溶液では, 硬度が高いほど最大荷重が大きくなった。Ca-Mg混合溶液では, 硬度が高いほど最大荷重が増す傾向がみられ, Caの馬鈴しょ硬化作用が認められた。Ca-Mg混合溶液で, KM, NRでは硬度が高くなるに従いa*, b*値が小さくなる傾向があり, くすんだ色になっていった。SQでは, b*値が負に移動し, 青みが強くなった。アントシアニン残存率は, Ca-Mg混合溶液において, 3品種とも硬度が高くなるに従い, 残存率が減少する傾向を示した。硬化による切片の色素の溶出抑制には繋がらなかった。

When a humanoid robot works with a human, it is needed for the robot to pass and receive objects. The robot has to detect that the laden objects are operated by the human on the whole body in object passing tasks. It is important that the robot detects not only push but shear generated by pulling action and twist generated by rotating action for the robot to detect human operations. In this paper, we dispersedly arranged 347 multi-axis soft tactile sensors to a humanoid robot. The multi-axis soft tactile sensors are small muti-axis sensors with urethane structure and they can be placed densely on body of a humanoid. We calculate a deformation vector from the deformation of sensor's upper surface using the output of a muti-axis soft tactile sensor. Next, we suggest the method to detect deformation state in contact surface consisting of soft tactile sensors using deformation moment and average of deformation vectors in the contact surface. Finally, we confirmed the usefulness of the fullbody tactile sensor cover and contact state detector by object passing experiment between a human and a robot.

It is preferable that robots have soft outer cover and give themselves fewer impact in contact with humans or surroundings. Although self-protection is one of the most important functions and inevitably required for robust robot architecture, Simple introducing thick “flesh” to a robot tends to impede the movability and generality. In this paper, we have realized soft and thick outer cover by multilayered and distributed softness, and have introduced joint protection by dislocation and auto recover function. Finally, we realized various contact behaviors by the robot with distributed soft cover and joint dislocation ability.

The characteristic anthocyanin, vitamin C, dietary fiber and sucrose contents of new types of colored potatoes were studied. The total dietary fiber level in the violet, red and yellow potatoes w[ere 0.75, 0.66 and 0.85o%, respectively. The total vitamin C contents of the violet, red and yellow potatoes were 25.3, 14.l and 31.5mg/100 g, respectively, while the anthocyanin contents of the violet, red and yellow potatoes were 142,148 and 17 mg/100 g, respectively. The main anthocyanin structures in the violet and red potatoes were determined to be petanin and pelanin by FAB-M S and ^1 H-NM R analysis. The red potato anthocyanin was very stable to heat and UV irradiation. Sucrose in the red and yellow potatoes increased during low-temperature storage.
