Title: Preparation, Evaluation and Storage of Preserve Made from Amla Cultivars Grown in Kandi Area of Punjab State Authors: Ranote, P S; Hothe, R K; Bawa, AS Abstract: Studies on fruit characteristics, physico-chemical analysis of fresh pulp and storage quality of preserve were carried out on Amla varieties grown in Kandi area, viz, Chakaiya, Francis and Kanchan. The data helped rank these varieties for preferance as: Francies> Chakaiya > Kanchan, as fruits of Francis variety were characterized with highest fruit mass of 40.65 g. shape index of 0.84, seed:pulp ratio of 1.16.6, TSS (10°Brix), pectin (0.54 per cent), protein (0.73 per cent) and overall sensory score. Fruits of Chakaiya variety were placed next due to its overall sensory performance, shape index of 0.83, seed: pulp ratio of 1.16 and protein (0.71 per cent), with high levels of tannins (1.09 per cent). Fruits of Kanchan variety were characterized by high level of ascorbic acid (540 mg/100 g). Ascorbic acid suffered the highest losses during processing (75 per cent) and upon storage (40 to 43 per cent). Reducing sugars, TSS and pH increased during six month storage of preserve at ambient temperature (12-38°C) while acidity declined. The tannins decreased from 8.0 to 10.3 per cent. Varieties and storage period showed significant effects on sensory scores (p < 0.05). All the three varieties were suitable for preserve making. Page(s): 461-465

Title: Effect of Temperature on Solubilization of Tricalcium Phosphate by Pseudomonas corrugata Authors: Pandey, Anita; Palni, Lok Man S; Mulkalwar, Pariksha; Nadeem, M Abstract: Pseudomonas corrugata, a soil isolate, initially obtained from a temperate location in Sikkim (Himalaya), was examined for its tricalcium phosphate solubilizing ability along a wide temperature range, from psychrophillic to mesophillic. The phosphate solubilization, by indirect petridish assay, was in conformity with the results of direct estimation of phosphate solubilization in broth. While the maximum solubilization was found to occur at 21°C, the bacteria solubilized more phosphate at 4°C than at 28°C. The species showed affinity towards lower temperature range. The study has implications for developing carrier-based microbial inoculants for improved growth of plants in the mountains. Page(s): 457-460

Title: Applications of Polymer-supported Reactions in the Synthesis of Pesticides I: Alkylation and Acylation of N-Hydroxy Phthalimide Authors: Pawar, N S; Kapadi, U R; Hundiwale, D G; Kumbhar, P P Abstract: N-Aikyloxy and N-acyloxy phthalimides have been synthesized in high yields by alkylation and acylation, respectively, of N-hydroxy phthalimide using polymer- supported anion of N-hydroxy phthalimide. The advantages of this rapid method are extremely mi ld reaction conditions, easy work-up and clean reaction without undesired byproducts. Page(s): 454-456

Chemical and Chemi-mechanical Processes for Degumming of Ramie Fibre and their Characterization by XRD, FT-IR and Microscopic Methods

Title: Chemical and Chemi-mechanical Processes for Degumming of Ramie Fibre and their Characterization by XRD, FT-IR and Microscopic Methods Authors: Boruah, R K; Baruah, P P; Bordoloi, A K; Rahman, A Abstract: Decorticated Ramie collected from Ramie Research Station, Sorbhog, Assam, India were degummed, using both chemical and chemi-mechamcal processes. Microstructural and morphological properties or these degummed fibres were studied by XRD, FT-IR and microscopic methods. The crystallinity percentages were found to be 28 and 27 per cent for the samples chemically treated (M1), and chemi-mechanically treated (M1), respectively. The crystallite sizes were found to be increased in the directions normal to both (002) and (040) reflection planes for the samples M and M 1 from that or decorticated ramie Without treatment (R). Results indicate that these degummed fibres are suitable for use as a raw material for fibre and pulp-paper industries. Page(s): 449-453
