The effect of fermentation, storage and stewing on the content and composition of anthocyanins as well as antioxidant capacity of red cabbage was studied. The observation of anthocyanins profile by HPLC-DAD-MS/MS was conducted. Red cabbage products contained twenty different nonacylated and acylated anthocyanins with main structure of cyanidin-3-diglucoside-5-glucoside. Treatments applied affec...

Polymerase chain reaction (PCR) methodologies for detection of pathogens in environmental samples are currently available. However, positive amplification products for any set of primers only signal that the appropriate target nucleic acid sequences were present in the sample. The presence of the amplification products does not imply that the target organisms were viable. Here we show that PCR ...

Although, beetles of the genus Tribolium first evolved as saprophylic insects, they have adapted to the stored products environment for several thousand years. In this study reproductive strategies are described for eight species of Tribolium that are known to occur in this environment. Experiments were conducted under the same conditions for every species, and several life history traits, incl...

Yukishita kyabetsu, cabbage (Brassica oleracea L. var. capitata L) that is cultivated or stored under snow cover for several months, was analyzed before and after snowfall; the sugar content, which imparts sweetness, mostly retained. Meanwhile, nitrate nitrogen (nitrate ion) concentration, causes astringency, decreased. In analysis using a taste sensing system, astringency bitterness decreased ...

Maintaining the long-term integrity of nucleic acids in the laboratory has traditionally required the use of freezers. However, novel nucleic acid stabilization technologies may allow for the storage of DNA and RNA at room temperature in a cost-effective, environmentally friendly manner. In this study, we evaluated two novel products for room temperature DNA storage: Biomatrica's DNA SampleMatr...

A laboratory study was conducted to investigate the effects of natural products on the reproduction and damage of Callosobruchus maculatus, the cowpea weevil, on cowpea seeds at Botswana College of Agriculture in Gaborone, Botswana. The cowpea variety Blackeye was used in the study. Fifty grams of each plant product (garlic, peppermint and chilies) was added to 500 g of the cowpea seeds. Findin...
