Pepper is one of the most popular vegetables for people. It is rich in nutrients, full of spicy taste, and is grown widely. Pepper is native to tropical South America and is sensitive to low temperatures. It is not tolerant of low temperatures. Its storage temperature is usually 8-12°C, and it can easily cause cold damage if it is less than 6°C. Symptoms of chilling injury, soft water immersed in water, or the appearance of decolorized round spots of water rot, and then infected with bacteria and rotting. Storability Due to the higher storage temperature of peppers, it is easy to grow pathogens, the storage stability is poor, and the preservation work is difficult. In general, dark-green, thick-skinned and spicy-maturing late-maturing varieties are resistant to storage and have strong resistance to disease and loss of water dispersion. In the storage work, attention should also be paid to the impact of field diseases. Chili fields with multiple diseased patches are not resistant to storage, and the peppers in the re-harrowing plots are not resistant to storage. The lack of fertility, drought or wet land plots of peppers are also not resistant to storage. Pepper is very sensitive to ethylene and ethylene can stimulate it to turn red and mature. Elimination of ethylene is also an important task for pepper preservation. The common disease in common diseases of pepper is soft rot, a field disease that often erupts during storage. Common diseases during the storage of pepper are white mold and black mold. Reducing the occurrence of diseases is an important task for pepper preservation. Storage method (refrigerated) 1, the warehouse should be strictly disinfected with formaldehyde, peracetic acid, bleach and other fumigation, spraying, and thorough disinfection. 2. Harvesting is to be carried out at the nearest harvest and the plots with few diseases and strong growth are selected. The chili fruits must be full, firm in texture, complete in fruit, dark in skin color, and excluded from inferior fruits and fruit. Packing or packing, try to avoid collisions and squeezing during transportation. 3. Dipping the drug in the bactericidal preservative for 2-3 minutes to remove surface germs and provide a protective layer for the pepper. After drying, precool the storage. Pre-cooling should be thorough and rapid. 5, bagging will be pre-cooled after the completion of the pepper into the pepper fresh-keeping bags, every 5-10 kg bag, tie. Fresh-keeping bags should be made of moisture-permeable PVC bags to prevent “sweat†and gas poisoning (carbon dioxide). When the carbon dioxide reaches 5%, the air should be released and the air release time is about 1 hour. 6, refrigerated temperature control at 8 °C, select the temperature difference of 0.5 °C. 7, anti-mildew during storage must pay attention to mildew, found moldy phenomenon, smoked in time with fresh smoke. With proper measures and conditions, peppers can be kept fresh for 2.5-3 months.
RT-PCR Test Reagent Kit Of COVID-19(ORF1ab, N)
The RT-PCR Test Reagent Kit Of COVID-19(ORF1ab, N) is a real-time RT-PCR test intended for the qualitative detection of nucleic acid from the SARS-CoV-2 in upper and lower respiratory specimens (such as anterior nasal swabs, mid-turbinate nasal swabs, nasopharyngeal swabs, oropharyngeal swabs, sputum, lower respiratory tract aspirates, bronchoalveolar lavage, and nasopharyngeal wash/aspirate or nasal aspirate) from individuals suspected of COVID-19 by their healthcare provider.
Results are for the identification of SARS-CoV-2 RNA.The SARS-CoV-2 RNA is generally detectable in upper and lower respiratory specimens during the acute phase of infection.
Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infective status. The agent detected may not be the definite cause of disease. Positive results do not rule out bacterial co-infection with other viruses.
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations, patient history, and epidemiological information. The COVID-19 RT-PCR Detection Kit is intended for use by qualified trained clinical laboratory personnel specifically instructed and trained in the techniques of real-time PCR and in vitro diagnostic procedures.
