And Storage

Assam lemon is one of the most important fruit of Assam and it is used for culinary purpose due to its fragrance and acidic content. Though Citrus fruits are non-climacteric in nature, depending on the temperature and storage duration, chemical composition of fruits may change. In this experiment different treatments viz T0: Control, T1: Chlorination (4%), T2: Chlorination (4%) + Polyethylene (300 gauge thickness), T3: Chlorination (4%) + perforated polythene (with pinholes), T4: Chlorination (4%) + individual shrink wrapping, T5: Chlorination (4%) + tray packaging used to study the storage life and post harvest quality of Assam Lemon fruits. The effect of these treatments on citric acid, respiration, fruit texture and colour were studied. Among all the treatments, individual shrink wrapping (T4) of Assam Lemon fruit stored at ambient temperature (30-320C and 80–85% RH) was found to be beneficial because it helped to extend the shelf life without deterioration in quality of fruit. Shrink wrap packaging retained the freshness, colour and firmness of the fruit up to 1 month without any decay

Combustion Behaviors

Crystalline multiferroic BiFeO3 powders were directly synthesized by sol-gel auto-combustion method. The gels, derived from the solutions of 2-methoxyethane, metal nitrate and citric acid, exhibited the self-propagating combustion behaviors at ambient temperature when it is ignited in air. After auto-combustion, the dried gels transformed into crystalline BiFeO3 powders and no further calcination was needed. The nature of auto-combustion was ascribed to heat-induced redox between NH4NO3 and carboxyl group. The TG-DTA was carried out to study the auto-combustion of dried gels. The synthesized powders were characterized by XRD and SEM techniques.

Lemon cordial was prepared and its storage conditions were studied. The prepared cordial was kept in 250 ml sterilized glass bottles, sealed and stored at ambient temperature (22°- 37°C) for 360 days. The chemical composition, keeping quality and consumers acceptability of the product was analyzed at an interval of 15 days up to 120 days and then at an interval of 30 days upto360 days. Except vitamin C content, no noticeable change was observed during the storage.

Main Factor

Green bananas, acidified in the can with citric acid in a 2% brine and canned in plain tin cans (.751bs/BB inside), were spoiled by complete detinning of the containers when stored at ambient temperature (85-90° F, 29.4-32.2° C) for 3 months. The processed green bananas had a N03 as N content ranging from 243 to 417 p/m. In green banana pulp dispersions in citrate and acetate buffers canned in plain tin containers, 1 p/m N03 as N dissolved approximately 26 p/m Sn. The high nitrate content of the green bananas was undoubtedly the main factor involved in the detinning of the containers. Water blanching under different conditions of time and temperatures failed to lower the nitrate content of the green bananas. Canning of the acidified green bananas in F enamellined cans did not prove feasible because of the rapid dark discoloration resulting a short time after the cans were opened.

Ambient temperature self-blowing mimosa tannin-based non-isocyanate polyurethane (NIPU) rigid foam was produced, based on a formulation of tannin-based non-isocyanate polyurethane (NIPU) resin. A citric acid and glutaraldehyde mixture served as a blowing agent used to provide foaming energy and cross-link the tannin-derived products to synthesize the NIPU foams. Series of tannin-based NIPU foams containing a different amount of citric acid and glutaraldehyde were prepared. The reaction mechanism of tannin-based NIPU foams were investigated by Fourier Trasform InfraRed (FT-IR), Matrix Assisted Laser Desorption Ionization (MALDI-TOF) mass spectrometry, and 13C Nuclear Magnetic Resonance (13C NMR). The results indicated that urethane linkages were formed. The Tannin-based NIPU foams morphology including physical and mechanical properties were characterized by mechanical compression, by scanning electron microscopy (SEM), and thermogravimetric analysis (TGA). All the foams prepared showed a similar open-cell morphology. Nevertheless, the number of cell-wall pores decreased with increasing additions of glutaraldehyde, while bigger foam cells were obtained with increasing additions of citric acid. The compressive mechanical properties improved with the higher level of crosslinking at the higher amount of glutaraldehyde. Moreover, the TGA results showed that the tannin-based NIPU foams prepared had similar thermal stability, although one of them (T-Fs-7) presented the highest char production and residual matter, approaching 18.7% at 790 °C.

Excised Tissue

Previous SEM studies of liver cytoskeletal elements have encountered technical difficulties such as variable metal coating and heat damage which occurs during metal deposition. The majority of studies involving evaluation of the cell cytoskeleton have been limited to cells which could be isolated, maintained in culture as a monolayer and thus easily extracted. Detergent extraction of excised tissue by immersion has often been unsatisfactory beyond the depth of several cells. These disadvantages have been avoided in the present study. Whole C3H mouse livers were perfused in situ with 0.5% Triton X-100 in a modified Jahn's buffer including protease inhibitors. Perfusion was continued for 1 to 2 hours at ambient temperature. The liver was then perfused with a 2% buffered gluteraldehyde solution. Liver samples including spontaneous tumors were then maintained in buffered gluteraldehyde for 2 hours. Samples were processed for SEM and TEM using the modified thicarbohydrazide procedure of Malich and Wilson, cryofractured, and critical point dried (CPD). Some samples were mechanically fractured after CPD.
