On the surface, Robert Browning‟s poem, “Porphyria‟s Lover” is a straightforward piece. 1 The plot begins with the speaker, a man, being visited at night by his lover, Porphyria, and ends ultimately with him strangling her. It is a simple story, albeit a distressing one. As literary critic Catherine Ross notes in her article, “Browning‟s Porphyria’s Lover,” the “standard reading” of the poem is...

Lipid damages were studied during a prolonged storage of canned fish. Albacore tuna was processed at two sterilization conditions (115°C, 74 min; 120°C, 40 min) and then stored up to six years. Analyses (lipid oxidation and hydrolysis, browning, fluorescent compounds formation) were achieved on the lipids extracted from the white muscle of the fish and on the packing oils. Muscle lipids were pa...

Tyrosinase is a multifunctional, glycosylated, and copper-containing oxidase, which catalyzes the first two steps in mammalian melanogenesis and is responsible for enzymatic browning reactions in damaged fruits during post-harvest handling and processing. Neither hyperpigmentation in human skin nor enzymatic browning in fruits are desirable. These phenomena have encouraged researchers to seek n...

Griffiths ( 13) has presented evidence in(licating that the browning reactions of banana fruit result from the enzymic oxi(lation of (lopamiiine (3.4 (lih-droxyphenylethylaminei) hy pIolyphenoloxi(lase. Althoughi (lopamine does occur in various fruits andl vegetables (23), it has not previously b)een imiplicated as an important substrate in browning reactions. The present investigation was unde...

There are few available compounds that can both control browning and enhance microbial safety of fresh-cut fruits. In the present study, the antibrowning ability of sodium acid sulfate (SAS) on "Granny Smith" apple slices was first investigated in terms of optimum concentration and treatment time. In a separate experiment, the apple slices were treated with water or 3% of SAS, calcium ascorbate...

We have much pleasure in announcing that the lis. 100 prize offered by Messrs. Thacker, ?Spink & Co., for the best essay on 'How Plague is spread,' has been awarded to Major S. Browning Smith, I.M.S., Plague Medical Officer, Punjab, for his paper on 'The Spread of Plague' which appeared in our July number. We have to thank Colonel Lukis, Principal of the Medical College, Calcutta, for kindly ju...

Fresh-cut banana slices have a short shelf-life due to fast browning and softening after processing. The effects of atmospheric modification, exposure to 1-MCP, and chemical dips on the quality of fresh-cut bananas were determined. Low levels of O2 (2 and 4 kPa) and high levels of CO2 (5 and 10 kPa), alone or in combination, did not prevent browning and softening of fresh-cut banana slices. Sof...

aril browning threatens production, consumption, and exports of pomegranates, because affected fruit cannot be externally distinguished from healthy fruit. this study compared the mineral, biochemical composition, and related enzyme activities in affected brown arils with healthy ones in ‘malase saveh’ pomegranates. the results indicated that concentrations of cu in the aril and k, mg, and mn i...
