Exopolysaccharide Production from Lactic Acid Bacteria Isolated from Fermented Foods

Isolates of lactic acid bacteria were obtained from non-dairy fermented foods (Mettwurst salami, Prosciutto ham and black olives). Their species were identified and they were investigated for their ability to produce exopolysaccharides. A reference yoghurt culture (Streptococcus thermophilus) and an exopolysaccharide producing isolate (Leuconostoc mesenteroides - Isolate 3) were grown in mESM broth under aerobic conditions at 25°C. They produced up to 600 mg/L and 530 mg/L of exopolysaccharide, respectively. Viscosities of the final fermentation broths were much higher in comparison to the isolated exopolysaccharide solutions. The addition of whey protein concentrate (0.2% w/v) to the extracted exopolysaccharides slightly increased the viscosity of the solutions.     

利用动物血发酵酱油

各种屠宰动物血是一种资源量很大的蛋白质,营养丰富,在食品开发方面,大规模利用动物血的报道不多,本文报道了一种利用动物血制作酱油的新工艺。利用动物血制作酱油的主要优点是质量高、成本低。采用本文报道的工艺制作的血酱油成功地消除了血的腥臭气,并且酱香浓郁,产品的各项主要指标均达到了优质酱油的水平,氨基氮含量达到1.1g/100mL,为屠宰动物血的大规模利用提供了一条新的途径。利用酵母和乳酸菌进行后处理,对血酱油的质量提高具有重要意义,并对增香处理的工艺条件进行了初步探索。     

Production losses from mastitis: carry-over from the previous lactation

The study examined whether elevation in SCC in the second lactation was associated with reduced milk production in the third lactation. Lactation records from 10,705 Holstein cows from 770 herds were taken from the Dairy Records Processing Center at Raleigh. Cows in the data set were selected so that no SCC test in the first lactation was elevated above a linear score of 4.5 (no mastitis in the first lactation). Using actual and mature equivalent milk production in the first lactation as a baseline, effects of elevated SCC on production in the second and third lactations were examined using linear regression. The effect of high SCC during a cow's current lactation was found to be essentially the same as previously reported by other investigators. An increase in the lactation average linear score of 1.0 was associated with a decrease of approximately 200 kg of milk per lactation. Limited carry-over effect of elevated SCC during the second lactation was found in the third lactation. For third lactation milk production, the effect of increased SCC during the preceding (second) lactation was only about 20 to 30% as much as the effect of SCC increases in the third lactation.     

Properties of gum exudates from selected Albizia species from Tanzania

Gum samples from three selected Albizia species from Tanzania have been analysed and their commercial potential determined by comparing their properties with those of Albizia zygia and Acacia gums. The properties of the gum exudates from Albizia amara, Albizia pertesiana and Albizia harveyi have been found to be similar to those of A. zygia gum except that their aqueous solutions possess slightly lower viscosity and higher levels of tannin. The Albizia gums were much less soluble in water than Acacia gums; however, their methoxyl contents and acid equivalent weights (AEW) were similar to those of some Acacia gums.     

乌拉圭的嘉颂酒庄

没有多少葡萄酒消费者知道乌拉圭也是一个产酒国。事实上,乌拉圭是南美洲第四大葡萄酒生产商。尽管乌拉圭的葡萄酒产量仅占整个大陆的4%左右,但当你意识到,如果与邻国阿根廷和巴西对比的话,乌拉圭的面积有多么小时,那么这个"4%"着实令人印象深刻。

法拉利创新的启示

<正>21世纪了,不是只有印刷产业必须求新求变,即使经营超级跑车(下文简称:超跑)品牌这样令人羡慕的行业,面对新时代剧烈的市场变化,也得硬着头皮向前冲锋。2 0 0 2年德国血统的超跑品牌保时捷,由第二代接班,改变市场策略,利用原来保时捷丰富的品牌资源,相继推出卡宴(Cayenne)运动休旅车和Panamera四门轿跑车,打破了保时捷超跑的传统形象,并让保时捷从原来年销量不到4万辆的小众市场破茧而出,2012年创下一年卖出14多万辆的销售新规模。这被商业杂志赞誉为有史以来最成
