酸乳与酸乳饮料的区别及其他

一是食品属性不同,前者为乳制品,后者则属于饮料;二是蛋白质含量不同,酸乳的蛋白质含量≥2.9g/100g,而酸乳饮料仅≥1.0g/100g;三是乳酸菌数不同,酸乳(发酵后经热处理的产品除外)要求乳酸菌数≥1×106CFU/mL,而未杀菌型酸乳饮料要求出厂期≥1×106     

羊栏镇上的那锅酸汤鱼

羊栏镇原是三亚西郊的一个小镇,从市区前往天涯海角,这里是必经路段。这个镇子主要聚居着回族居民,于是便弥漫着一股伊斯兰气息。羊栏镇现在改称凤凰镇,但人们还习惯地称此为羊栏,名字令人印象深刻。我到三亚之前就听说过这里的回族酸汤鱼独具风味,抵达三亚后,便找机会让朋友带着,前往这个向往已久的地方慰劳肚里的馋虫。     

Occurrence of odor problems in drinking water of major cities across China

A comprehensive investigation into the occur-rence of odor problem at 111 drinking water treatment plants （DWTPs） in major cities across China was undertaken using both flavor profile analysis （FPA） and gas chromatography-mass spectrometry （GC-MS）. Eighty percent of source water samples exhibited odor problems, characterized by earthy/musty （41%） and swampy/septic （36%） odors, while the occurrence rate was lower （45%） in the finished water. Source water from rivers exhibited more pollution-origin odors, such as the swampy/septic odor, while that from lakes and reservoirs exhibited more algae- origin odors, such as earthy/musty odors. The occurrence rate of 2-methylisoborneol （2-MIB） in the surface source water samples was 75%, with 7% of samples containing 2- MIB concentrations of over 10 ng.L-1. The earthy/musty odor in the lake/reservoir water samples was mainly caused by 2-MIB （linear regression coefficient, R2= 0.69）, while the correlation between 2-MIB concentration and the earthy/musty odor intensity samples was weak （R2= 0.35） in the river-source water These results will be useful for the management of odor-quality problems in drinking water of China.     

骑摩托旅行,乐哉!

古人说:"骑驴看唱本,走着瞧"我不知道这是一种什么样的意境。撇去这句俗语中"秋后算账"的引伸义,我想古代文人骑着驴,在天地间一任小驴放开四蹄漫无目的地走,而在驴上一颠一颤间读着好看的文章,的确是别有一番风味,     

葛根与臭菜

前段时间,我和几位朋友一起去西双版纳游玩,到了午饭时间,我们走进了一家名叫"山里人家"的土菜馆,品尝当地独具风味的美食。由于这家菜馆的老板是我朋友的战友,因此,老板娘亲自下厨为我们烧几道我们平时吃不到的菜。老板娘吩咐了几
