Newly harvested Russet Burbank potatoes were cured for 3 weeks at 15.5 C. The cured potatoes were individually film wrapped either immediately, or stored at 7.2 C for 12 weeks and then film wrapped. The film wrapped potatoes stored at 20 C were compared with nonwrapped potatoes stored at 7.2 C or 20 C for cooking time and various sensory characteristics. The sensory and cooking characteristics of the film wrapped potatoes stored at 20 C were better than the baking characteristics of nonwrapped potatoes stored at 20 C but not at 7.2 C. Individual film wrapping of potatoes significantly preserved the baking and cooking quality of potatoes during storage at 20 C, 60% RH.  相似文献

A study was conducted on twenty indigenous goat kids allocated into two different groups. All animals were offered ad libitum rice straw and berseem hay (40:60). Group I (T1) was fed concentrate mixture (100 g/d). Group II (T2) was supplemented with urea molasses mineral block (200 g/d). The experiment lasted for 90 days. There was significant decrease in serum sodium (60.68 mEq/L), increase in serum potassium (34.50 mEq/L) and increased activity of AST (340.42 U/L) and ALT (164.96 U/L) was observed in kids of group T2 in comparison to the controls (T1). On histopathological examination mild degenerative changes in kidney of group T2 with congestion in intertubular vessel, granular cytoplasm of the epithelial cells in PCT and DCT, necrosis and swelling of the epithelial cells, congestion of vessels and cloudy swelling was observed in PCT and DCT. Albuminious mass was also present in tubule. On histopathological observation of liver of kid of group T2 oedema in liver parenchyma and proliferation of fibrious tissue in periportal area was observed.  相似文献

Synthesis of some new substituted [3-(3-chloro-4-fluorophenyl)-2-oxo-3,4-dihydro-2H-2lambda(5)-benzo[e][1,3,2]oxazaphosphinin-2-yl]-(aryl/alkyl)methanols (7a-k) based on the Pudovick reaction was accomplished in the presence of niobium pentoxide (Nb(2)O(5)) without using an external chiral ligand. Nb(2)O(5) appears to form the metal complex intermediate catalyst system (6) by reacting with 3-(3-chloro-4-fluoro-phenyl)-3,4-dihydrobenzo[e][1,3,2]oxazaphosphinine-2-oxide (4), which not only directs the Pudovick addition reactions of aldehyde but also increases the yields and purity of the products. These compounds exhibited a lethal effect on whip smut of sugarcane and were degraded in the environment in the presence of bacteria and fungi to nontoxic phosphate residues that act as possible plant nutrients. Thus, a new class of benzooxazaphosphininyl methanol derivatives that act in synergy both as antipathogens and as plant nutrients in the environment have been discovered.  相似文献

Studies were conducted by injecting/feeding white spot syndrome virus (WSSV) derived from infected shrimp, Penaeus monodon (Fabricius), to different life-stages, namely post-larvae, juveniles, sub-adults and adults of Macrobrachium rosenbergii (de Man). The disease was also induced in brood stock, and the eggs and larvae derived from these animals were subsequently tested for WSSV infection. All the stages except egg used for the experiment were found WSSV positive in histopathology, cross infection bioassay and polymerase chain reaction (PCR) analysis. Experimentally infected post-larvae and juveniles showed a high percentage of mortality and an increased rate of cannibalism. The cumulative mortality in post-larvae was up to 28%; with 28–40% cannibalism resulting in a maximum loss of up to 68%. In juveniles, observed mortality and cannibalism were 10–20% and 6.7–30.0%, respectively, and the maximum loss recorded was 50%. In sub-adults, mortality ranged from 2.8 to 6.7%, cannibalism was up to 20% and the total loss was up to 26.7%. Sub-adults and adults were found to be more tolerant to the infection as evidenced by the mortality pattern. A nested (two-step) PCR resulted in a 570-bp product specific to WSSV in all stages, except the eggs.  相似文献
