Effect of multiple 1-MCP treatments to extend shelf life of tomato
No full textEthylene is a plant growth hormone responsible for ripening and senescence of fresh produce. But production of excess ethylene leads to over ripening and facilitates microbial growth thereby reducing the shelf life. Therefore control over ethylene action is required. To increase shelf life of fresh produce 1-Methylenecyclopropene (1-MCP) ethylene antagonist shown promising result by inhibiting ethylene response at receptor level. The current 1-MCP treatment requires a storage room with controlled atmosphere overnight. However this treatment is effective only for the initial period of time as continuous formation of ethylene receptors triggers ripening. Controlled Release Packaging (CRP) technology can be used as an alternative to existing 1-MCP treatment by providing the ability to replenish 1-MCP and prolong is exposure to fresh fruits. The first objective of this study was to evaluate the effect of multiple 1-MCP treatments on quality attributes of fresh tomatoes. This study was conducted at turning stage of tomatoes using three treatments: 1) control (no 1-MCP), 2) single 1-MCP treatment (1200nl) and 3) multiple 1-MCP treatments (100nl/day for 12 days). The multiple 1-MCP treatments prolonged the shelf life of tomatoes by maintaining quality attributes including weight, color, firmness, pH and total soluble solids (TSS) at room temperature compared to the single 1-MCP treatment. Not all quality attributes were affected to the same extent, the strongest effect of multiple 1-MCP treatments was on firmness of the tomatoes and not much difference was noted on TSS and pH of tomato juice. The second objective was to quantify the release of 1-MCP through Tyvek, LDPE and PLA polymer sachets at room temperature under 90% RH to test their potential usage as CRP film material. The release of 1-MCP through Tyvek sachet is almost 90% in 10-12 hours whereas LDPE sachet has a slower a release around 10% in 10-12 hours. Both polymers have potential use as an active layer in CRP system. PLA sachet does not release 1-MCP, but it may be used as a barrier layer of the package of CRP system.M.S.Includes bibliographical referencesby Tulsi Pate

Corrosion Inhibitory Ability of Ocimum Sanctum Linn (Tulsi) Rinse on Ion Release from Orthodontic Brackets in Some Mouthwashes: An Invitro Study
No full textIntroduction: In the oral environment, orthodontic appliances are exposed to potentially damaging physical and chemical agents which may cause metallic corrosion. Corrosion will occur continuously in mouth, due to release of irons with abrasion by food, liquids etc. The purpose of this study was to measure the amount of metal ion release from orthodontic brackets when kept in different mouthwashes and effect of tulsi rinse on ion release when combined with different mouthwashes.
Methods: Three hundred and twenty stainless steel brackets (0.022”) were divided randomly into 8 equal groups and immersed in Mouthwash-A and, Mouthwash-B and mouthwash-C and distilled deionized water. These mouthwashes and distilled deionized water were all separately mixed with tulsi rinse and incubated at 37°C for 45 days. Nickel, Chromium, iron, copper and manganese released from the orthodontic brackets were measured with an inductively coupled plasma spectrometer.
Results: Ion release in deionized water was higher (p0.05) in nickel, chromium, iron and copper ion release in the Mouthwash-A and Mouthwash-C. Tulsi rinse showed significant reduction (p<0.05) in all ion release in 3 mouthwashes used along with distilled deionzed water group.
Conclusion: If ion release is concerned, Mouthwash-C mixed with tulsi rinse might be better option than Mouthwash-A as well as Mouthwash-B for orthodontic patients with stainless steel brackets
Effect of feeding Tulsi (Ocimum sanctum) Leaf Powder in diet of broilers for quality meat production
No full textABSTRACT The research was conducted to study the effect of dietary supplementation of tulsi (Ocimum sanctum) leaf powder on meat cholesterol and serum lipid profile of broiler from day old to six weeks of age. A total of 72 (Arbor-Acres) day old chicks were used in this study. Four levels of a Tulsi (Ocimum sanctum) leaf powder at the rate of 0.00%, 0.25%, 0.50%, and 1% were incorporated into the basal diet for six weeks. Feeding period for all groups was lasted for 42 days. All the birds were reared under standard managemental conditions. The observations were recorded for cholesterol content of meat and serum lipid profile of broilers. Supplementation of tulsi leaf powder at the rate of 1% for 42 days showed the significant decrease (P<0.01) in breast muscle and thigh muscle cholesterol. Group T 3 showed the significant reduction in thigh muscle cholesterol but not in breast muscle cholesterol. The average serum total cholesterol was reduced significantly (P<0.01) in T 4 group but not in T 3 . The average serum HDL cholesterol was increased significantly (P<0.01) in T 3 and T 4 . The average serum triglycerides were significantly reduced in T 3 and T 4 . But higher reduction obtained in birds fed with 1% tulsi leaf powder in diet. The average serum LDL cholesterol was significantly reduced (P<0.01) in T 4 followed by T 3 group. The study concluded that supplementation of tulsi leaf powder at the rate of 1% in broiler diet for 42 days reduced meat and blood cholesterol levels of broiler
