Syrup https://myresearchjournals.com/index.php/iarjnfs/article/view/10350 Averrhoa bilimbi commonly known as bilimbi, is starchy and nutritious fruit rich in ascorbic acid and minerals. The study was aimed for the development of pasteurized bilimbi syrup, a value added and shelf stable product from bilimbi and thereby increase its market value. The heat penetration characteristics during pasteurization of the syrup packed in polypropylene bottles were studied. 29% of bilimbi syrup diluted using potable water to a concentration of 21ºBrix was selected by the sensory panel to serve as ready to drink after dilution. Animal studies to detect histological changes in cardiac, renal and hepatic tissues of experimental rats fed with bilimbi syrup did not show any changes in morphology. Shelf life of the product at ambient conditions (25 to 28ºC) was determined by analyzing the physiochemical changes in the product during storage for a period of 10 months. pH increased from 3.23 to 3.75, titratable acidity decreased from 2.54 to 1.07% of oxalic acid, total sugar increased from 59.59 to 65.07g/100g and ascorbic acid decreased from 44.61 to 34.25mg/100g on the eleventh month. The color of the product showed a rapid change affecting the L* value which decreased from 49.19 to 28.25. The sensory acceptability of the product also decreased which was below the acceptable level on the 11th month. Hence shelf life of pasteurized bilimbi syrup was estimated as ten months at ambient conditions. Ammu Dinakaran Ninisha Babu Divya K Vijayan Maya Raman T.

The product was found to be commercially sterile after retorting to an F0 value of 7.34 minutes. The heat penetration characteristics of the product was studied and revealed a total process time of 30.38 minutes to attain the above F0 value and the cook value was 66.03 minutes. The characteristics of the see through retort pouch used for the study was analysed and our results showed that it had good barrier properties and is suitable for food contact applications. Tomato is known as a rich source of lycopene, thus in this study the ready to eat tomato curry was also analysed to determine the changes that occurred in the lycopene content during processing. Shelf life studies conducted revealed a shelf life of one year at ambient temperature (26 to 28°C). Ammu Dinakaran Ninisha Babu Maya Raman Akshaya Ravindran T. V. Sankar T.

This is partly caused by the lack of effort spent in exploring marine actinomycetes, whereas terrestrial actinomycetes have been, until recently, a successful source of novel bioactive metabolites. Furthermore, scepticism regarding the existence of indigenous population of marine actinomycetes arises from the fact that the terrestrial bacteria produce resistant spores that are known to be transported from land into sea, where they remain available but dormant for many years. Thus, it has been frequently assumed that actinomycetes isolated from marine samples are merely of terrestrial origin. It may be better to seek evidence instead that marine derived actinomycetes are metabolically active or capable of growing in the marine environment. Other useful characteristics include the display of specific marine adaptations, the formation of associations with plants or invertebrates and the demonstration of a role in nutrient cycling, all of which provide an indication that these bacteria are not merely present as dormant spores. When coupled with phylogenetic novelty, evidence for any of the above traits provides a strong case that the specific population under study can be considered as marine. As marine organisms live in a significantly different environment from those of the terrestrial organisms, it is reasonable to expect that their metabolites will differ considerably. Although actinomycetes can be readily isolated from marine sediments using appropriate selective isolation techniques, it is only through the use of molecular phylogenetics, a clear picture of the diversity, distributions and taxonomic uniqueness of certain populations can be obtained. Once recognized as unique, this population can then be selected as the focal point for intensive natural product studies. Clearly, actinomycetes have the potential to continue to play a major role in microbial drug discovery, and the recent observations on significant population of marine-adapted actinomycetes occur in ocean sediments, could certainly emphasize the potential importance of these strains in future drug discovery efforts.
