Acid Lime

Sunkagati-1 is one of the commonly grown acid limes recommended for terai region of Nepal with main season production from Shrawan to Poush. In recent year, area of acid lime is increasing while no appropriate technology of postharvest is available for it. An experiment was carried out with an objective to assess the influence of edible oil coatings and packaging on storage life of acid lime fruit. Fruits were harvested at physiologically mature stage with smooth and shiny appearance and treated with four edible oils (coconut oil, mustard oil, sesamum oil and castor oil), liquid paraffin 10% wax emulsion and 25 micron low density polyethylene (LDPE) packaging. The study was conducted in completely randomized block design (CRD) with seven treatments and three replications. Fruits were kept at ambient condition (20±1.55 ºC, 65±6.5 % RH) till 24 days and analyzed for various postharvest physical, chemical and physiological parameters after 8th, 16th and 24th days of storage. The result showed that LDPE packaging has significant effect on reduction of physiological loss in weight (1.69 %), spoilage loss (5.17 %), higher vitamin C content (60.11 mg/100g), Titratable acidity (6.71 %) and development of marketable color viz., 100% yellow color. Also, coconut oil showed significantly better postharvest quality retention with reduced physiological loss in weight (10.83 %) and spoilage loss (10.45 %). This study concluded that LDPE packaging and coconut oil coating are the appropriate method to extend the storage life of acid lime in ambient condition of mid hills situation.

Capsicum is one of the high value vegetable crops in Nepal. Its demand in kitchen is increasing due to urbanization and increased awareness on its health benefit. Its commercial cultivation has been started in protected as well as open field conditions. It fetches higher price in market but has very short storage life under ordinary storage condition. An experiment was carried out to evaluate the modified atmosphere packaging (MAP) on extension of shelf-life of capsicum fruit. Fruit were harvested at full mature stage with smooth and shiny appearance from farmer's field grown under protected condition at Chitwan, Nepal. The fruits were brought to postharvest laboratory of National Horticulture Research Centre, pre-cooled for 3-4 hours, cleaned with muslin cloth and packed in 25 micron Low Density Polyethylene (LDPE) packaging with different number of pinhole sized perforations viz. without pinholes, eight pinholes, sixteen pinholes, twenty four pinholes and control (without MAP). The study was conducted in completely randomized block design with five treatments and four replications. Fruits were kept at coolbot storage (9.8+2 ºC, 86+5% RH) till 30 days and analyzed for various postharvest physical, chemical and physiological parameters at every 10, 20 and 30 days of storage. The result showed that LDPE packaging influenced on reduction of physiological loss in weight (PLW), spoilage loss, ascorbic acid content, TA, freshness, firmness and shelf life. The modified atmosphere packaging (MAP) without pinholes showed the minimum PWL (1.71%) and the optimum fruit freshness (4.76) but the spoilage loss was the maximum (14%). Among the packaging, MAP with 8 pinholes maintained majority of postharvest quality retention with reduced physiological loss in weight (4.15 %), freshness (4.5) and spoilage loss (2%).

Herein; we present a green synthesis method for magic sized nanoclusters (MSNCs) of CdSe. The formation of MSNCs was examined using various edible oils viz; olive oil; mustard oil; castor oil; coconut oil and cod liver oil as capping agents. The source of Selenium is cyclo-octeno-1;2;3-selenadiazole which was decomposed (typically at 150 °C) in high boiling solvent. The comparative study has been carried out to verify the effect of different edible oils as capping agents on formation of CdSe to form MSNCs. We observed that only a certain capping agent (oil) delivers MSNCs of CdSe with stable white light emission for more than 12 months. The so-generated CdSe MSNCs show bright white light emission when excited with 365 nm light. Finally; the long term stability of as-prepared MSNCs using certain oil as capping agent is reported.

Repeated heating of vegetable oils at high temperatures during cooking is a very common cooking practice. Repeated heating of edible oils can generate a number of compounds, including polycyclic aromatic hydrocarbons (PAH), some of which have been reported to have carcinogenic potential. Consumption of these repeatedly heated oils can pose a serious health hazard. The objectives of the present study were to evaluate the genotoxic and carcinogenic risks associated with the consumption of repeatedly heated coconut oil (RCO), which is one of the commonly consumed cooking and frying medium. The PAH were analysed using HPLC in fresh CO, single-heated CO (SCO) and RCO. Results revealed the presence of certain PAH, known to possess carcinogenic potential, in RCO when compared with SCO. Oral intake of RCO in Wistar rats resulted in a significant induction of aberrant cells (P < 0·05) and micronuclei (P < 0·05) in a dose-dependent manner. Oxidative stress analysis showed a significant (P < 0·05) decrease in the levels of antioxidant enzymes such as superoxide dismutase and catalase with a concurrent increase in reactive oxygen species and lipid peroxidation in the liver. In addition, RCO given alone and along with diethylnitrosamine for 12 weeks induced altered hepatic foci as noticed by alteration in positive (γ-glutamyl transpeptidase and glutathione-S-transferase) and negative (adenosine triphosphatase, alkaline phosphatase and glucose-6-phosphatase) hepatospecific biomarkers. A significant decrease in the relative and absolute hepatic weight of RCO-supplemented rats was recorded (P < 0·05). In conclusion, dietary consumption of RCO can cause a genotoxic and preneoplastic change in the liver.

ABSTRACT: The objective of this study was to explore the substitution of ractopamine by coconut or safflower oil in finishing pig diets. The study included 24 crossbred barrows weighing 78.00 ± 8.76 kg distributed in a randomized block design with four treatments and six replicates composed of: basal ration (BR), BR + 10 ppm ractopamine, BR + four 1 g capsules of safflower oil, and BR + four 1 g capsules of coconut oil. Performance evaluation showed that safflower oil, ractopamine, and coconut oil supplementation had a significant effect (P < 0.05) on weight gain and feed conversion. Carcass-related variables were also affected by the treatments (P < 0.05), with fat thickness 3 (FT3) reduced by the use of safflower oil, ractopamine, and coconut oil. Rib eye area was positively affected (P < 0.05) by diet, with ractopamine, coconut oil, and safflower oil supplementation treatments showing higher values than control diet treatment. The diets also affected fatty acid profiles (P < 0.05), with decreased myristic acid content in animals supplemented with ractopamine and safflower oil and increased deposition of palmitoleic and oleic acids in animals supplemented with coconut oil and safflower oil, respectively. Results suggested that both safflower oil and coconut oil can be used as substitutes for ractopamine.

Edible oil is of the most important and widely used processed foods. The study was carried out to assess the microbiological quality of edible oil (Shea butter, Coconut oil and Palm Kernel oil) from two geopolitical zones of the country. A total of thirty (30) samples were gotten from four (4) different markets in the two geopolitical zones. Bacteria and Fungi were isolated and identified base on cultural, microscopic, biochemical characteristics and antibiotic sensitivity test were carried out. The total heterotrophic bacteria count (THBC) of the sample ranged from 3.1 x 103 – 3.6 x 104cfu/ml. The total heterotrophic fungi count ranged from 1.0 x 102 – 6.4 x 103cfu/ml. The bacteria isolated and identified were Bacillus sp., Escherichia sp., Pseudomonas sp., Micrococcus sp., Staphyloccus sp., Enterobacterium sp., and Klebsiella sp while the fungi were Aspergillus niger, Aspergillus fumigatus, Rhizopus, Fusarium, Candida sp and Penicillium sp. The antibiogram of the Gram positive bacteria showed that all the organisms were sensitive to Erythromycin (100%) while Gram negative organisms were sensitive to Ofloxacin (100%) and Ciprofloxacin (100%). The bacterial load of all the samples fell within the minimum acceptable range according to CODEX standard. It is important that improve aseptic techniques be employed in the production, handling and marketing of edible oil.

Long-term use of inorganic fertilizers on leafy vegetables can increase soil acidity, harmful to the environment and leaving bad effects on human health. Organic fertilizer application is one of the safer alternatives with many beneficial effects by supplying nutrients for plant growth, environmental-friendly and producing an optimum quality of vegetables. Different organic amendment such as vermicompost, biochar and microbial compost has different effect on plant growth performance since good bacteria could improve structure of the soil and nutrient absorption. Therefore, this study aims to evaluate the effects of organic fertilizer on the growth performance and postharvest quality. The experimental design during planting was conducted in randomized completely block design with a factorial arrangement of treatmentswhile for postharvest quality study was conducted in completely randomized design. Organic fertilizer of vermicompost (110 g/plant), biochar (100 g/plant), microbial compost (80 g/plant) and chicken manure (37.5 g/plant) were treated on Pak choy two times on day 10 and day 24 after transplant. This research revealed the plant growth including plant height, leaf number and leaf length of Pak choy in all treatments were increased as growing stage increased. However, at the end of growing stage, microbial compost and vermicompost resulted in the highest of growth characteristics. In terms of postharvest quality, microbial compost showed the highest fresh weight and premium quality. This study proved that microbial compost at 80 g/plant exhibited optimum growth performance and the best postharvest quality of Pak choy.

The environmental issues caused by synthetic lubricant oils necessitate the need for an environment-friendly lubricant. In this study, a novel approach is proposed for developing an environment-friendly bio-lubricant by blending mustard oil, coconut oil and its methyl esters. Properties of the bio-lubricant are studied and compared with commercial ISO VG 32 oil. The best among various blends prepared are selected based on a decision matrix. The results revealed that this method helps in pour point depression and also in achieving excellent oxidative stability as compared to the base vegetable oil. The newly formulated oil has a pour point lower than that of commercial oil and is found to be highly biodegradable. The anti-wear characteristics of the oil are improved using boric acid, and the viscosity of the oil is improved using ethyl vinyl acetate for meeting the industrial standards. The newly formulated oil complies with industrial standards and can be used as biodegradable lubricant oil.
