Studies on the anthocyanin profile of <Emphasis Type="Italic">Vitis Vinifera</Emphasis> intraspecific hybrids (Monastrell × Cabernet Sauvignon)

A collection of 143 plants arising from crosses from Monastrell × Cabernet Sauvignon is available in our orchards. A 3-year study enabled us to identify the differences between the different plants. In 2005, we had studied the anthocyanin profile and color characteristics of the most promising hybrids as a part of a project to select those plants showing the most interesting enological characteristics. Differences in the anthocyanin profile were observed between Monastrell and Cabernet Sauvignon grapes, the hybrids showing, in general, an anthocyanin profile intermediate between these two varieties, although closer to that of Cabernet Sauvignon grapes. To the best of our knowledge, this is the first work to study how the anthocyanin profile of two premium Vitis vinifera varieties is inherited by the resulting hybrid plants.

Gamma-irradiation as a method of microbiological control,and its impact on the oxidative labile lipid component of <Emphasis Type="Italic">Cannabis sativa</Emphasis> and <Emphasis Type="Italic">Helianthus annus</Emphasis>

The effect of irradiation (0–20 kGy) on hemp and sunflower seeds was assessed, with specific reference to the oxidatively labile lipid component (unsaturated fatty acids and tocochromanols). Total protein, lipid, and solids content of the seeds did not vary with irradiation dose. Lipid hydroperoxide concentration increased significantly in the sunflower seeds (48 mmol kg⁻¹ lipid) and a significant increase in volatile secondary oxidation products was measured in both seeds (e.g. hexanal, heptanal, 1-penten-3-ol) with increasing irradiation dose. Irradiation at 5 kGy sterilised the seeds of all microbial contamination and irradiation doses of 20 kGy prevented germination. A loss of the antioxidant tocopherol was shown with increasing irradiation doses, although this was selective for specific tocopherol isoforms (α-tocopherol, β-tocopherol and γ-tocopherol).

Effect of alginate coating on the physico-chemical and microbial quality of pansies (<Emphasis Type="Italic">Viola</Emphasis> × <Emphasis Type="Italic">wittrockiana</Emphasis>) during storage

Edible flowers, such as pansies, are becoming more popular, but they are highly perishable. So, postharvest technologies are needed, being edible coatings a good alternative. Thus, the aim of this study was to evaluate the effect of alginate coating on physico-chemical and microbiological quality of pansies during cold storage (4 °C for 0, 7, 14, 21 days). Coated pansies maintained good appearance until 14 days of storage, 7 days more than uncoated ones. Flavonoids, hydrolysable tannins and monomeric anthocyanins, as well antioxidant activity, were higher in coated pansies when compared to uncoated ones, on all assayed storage times. Furthermore, after 14 days of storage, uncoated pansies presented microorganism counts higher than coated, namely yeasts and moulds, suggesting an effective barrier protection of the alginate coating treatment. In summary, alginate coating has potential for extending shelf-life and improving physico-chemical and microbiological quality of pansies.     

Flavonoids and furocoumarins distribution of unripe chinotto (<Emphasis Type="Italic">Citrus</Emphasis> × <Emphasis Type="Italic">myrtifolia Rafinesque</Emphasis>) fruit: beverage processing homogenate and juice characterization

The present study reports for the first time qualitative and quantitative data about flavonoids and furocoumarins distribution of unripe Citrus × myrtifolia Rafinesque homogenate, used as ingredient of the popular soft drink Chinotto. No data are available in literature about the chemical characterization of flavonoids and furocoumarins of the chinotto homogenate used to produce the industrial extract. Samples for analysis were therefore processed to better reproduce the crude materials used to obtain industrial chinotto extract: the whole fruits were cut in half, seeds removed, softly squeezed discarding part of the juice, and homogenized in small pieces. The polyphenolics separation was made by HPLC–PDA detector coupled to ESI/MS/MS in positive and negative mode. It has allowed the identification and relative quantification of 16 compounds, among which the flavone-C-glycoside lucenin-2, the 3-hydroxy-3-methylglutaryl flavanone glycoside melitidin and five polymethoxylated flavones have been detected for the first time in Citrus × myrtifolia. The flavonoids and furocoumarins distribution was compared with one of the Citrus × myrtifolia juice, and the antioxidant activity of both samples was assessed by ORAC (Oxygen Radical Absorbance Capacity)-fluorescein assay.

人&#183;自然&#183;设计

爱美之心,人皆有之。爱美、懂美、会美为人生一世中的一条虚线,它涵盖了文化素养、审美情趣、艺术修养、生活阅历等;人体、着装、饰物（服饰、首饰）三位一体乃人生之路的一条实线,它是外在的,是一种形式。外在形式与内涵（虚与实）二者有机结合,便会生成个人的气质与魅力。言谈举止潇洒大方,不做作,说起来容易,做起来就难了。“难得自然”。自然之美可谓无处不在,人类对自然不断地索取与破坏,使之越来越远离我们现代生活的空间,一个人在生活里若尽可能多地保存一些自然之美,他的生活理应其乐融融。 随着我国市场经济的发展,消费者的目光亦愈发挑剔,这对设计者来说无疑是个严峻的考验。首饰设计绝非是大拼盘,不论是传统的、民族的．欧美的、中西合壁的、具体或抽象的均离不开创新求异。别人的东西只能借鉴,只有不断地开拓新领域,向未知大胆探索,才可能独具匠心而不落英臼;创出名气,创出品牌。目下“ＷＴＯ””的大门即将开启,““狼来了”,如何与狼共舞,却是一件有意义的事。 人们追求完美的设计,其实完美是相对的．你自我感觉良好,他人不这么认为。关键在你的设计定位于哪一阶层,哪些消费群体。我们的设计力求使首饰更具感情色彩,更赋予亲和力。大自然所创造出来的每一种...     

SO 2 结合壳聚糖处理对采后鲜食葡萄品质的影响

以巨峰葡萄(Kyoho)为试验材料,分别以蒸馏水、各浓度壳聚糖溶液(0.5%、1.0%、1.5%)、二氧化硫(SO_2)保鲜剂、SO_2保鲜剂与各浓度壳聚糖溶液(0.5%、1.0%、1.5%)共同处理,后置于0℃环境下贮藏,通过对贮藏过程中果实各项生理指标的检测和分析,研究了壳聚糖降低SO_2对葡萄的伤害程度。结果表明:壳聚糖处理能够减少SO_2对失重率、落粒率、硬度等方面所带来的伤害。故壳聚糖对于巨峰葡萄的采后贮藏品质有着较好的控制,是一种具有广阔市场前景的葡萄保鲜剂。

拿破仑&#183;乔治桑&#183;生死恋

老上海最高档的法式西餐厅Maria有一道招牌名菜为“乔治桑鸡胸肉”。94岁老人、美食家孙曜东老伯伯介绍这原为法国宫廷菜，鸡肉是来自法国地道的白羽蓝脚布雷斯优质鸡，但对于上海，路途千里，八九十年前的空运十分昂贵且不普及快捷。从法国特地空运布雷斯鸡，哪怕是速冻，在当时条件是不可能的，因此都用本地草鸡替代。其实歪打正着，上海浦东三黄草鸡肯定比白鸡肉质细嫩，再经过正宗的法式调料及烹饪，还有特别的香料，味道十分可口且富异国风味，与上海菜的浓油赤酱十分接近。可惜我晚生了几年，对“乔治桑鸡胸肉”只能听描绘凭想象来体会，除非哪日有机会亲临巴黎，也不知道今日巴黎还会不会有人知道这道菜？
