Fresh sugarcane juice is sold by street vendors without any heat treatment in São Carlos, São Paulo, Brazil. Twenty-four samples of point-ofsale juice were tested by standard methods to determine heterotrophic bacteria, total and thermo-tolerant coliform counts, Salmonella, and parasites in the juice. 25% of samples showed poor sanitary conditions, with thermotolerant coliform levels higher tha...

A new method for dextran quantification has been developed and field-trialled in Jamaica, in association with the Sugar Industry Research Institute. The method uses a near infrared (NIR) polarimeter and a specific dextranase. The dextranase selectively breaks down the dextran into sugars of lesser specific rotations without affecting any other substance present in the juice. The initial dextran...

The influence of storage conditions on nitrate and nitrite contents, pH, and total viable bacterial count of raw vegetable juices was studied. Three different types of juices from an Estonian small-scale producer and five different types of home-made juices were analysed. Analyses were performed immediately after opening the commercial juice packages and immediately after preparation of a home-...

Alicyclobacillus are spoilage microbes of many juice products, but contamination of kiwi products by Alicyclobacillus is seldom reported. This study aims to investigate the whole production line of kiwi products in China to assess the potential risk of their contamination. A total of 401 samples from 18 commercial products, 1 processing plant and 16 raw material orchards were tested, and 76 sam...

The effect of oral administration of raw camel milk (5 ml/kg b.wt.) on ethanol– and aspirin–induced gastric ulcers was tested in rats. Oral administration of camel milk in rats with ethanol–induced gastric ulcer, significantly (P < 0.05) redudced the number of long ulcers, average length of ulcers, ulcer index and the volume of gastric juice. The total protein was significantly (P < 0.05) incre...

A rapid multiplex real-time PCR assay was developed to achieve highly specific, simultaneous detection of two kinds of mushrooms, Omphalotus guepiniformis and Lentinula edodes. Primers and TaqMan minor groove binder probes were designed according to the internal transcribed spacers 1-5.8S region of rDNA and evaluated by the specificity for fruiting bodies of 17 O. guepiniformis, 16 L. edodes an...
