  1. 16. Variation in protein precipitation and phenolic content within and among species across an elevational gradient in subarctic Sweden

    University essay from SLU/Dept. of Forest Ecology and Management

    Author : Elin Olofsson; [2010]
    Keywords : Phenolic compounds; Protein complexation; Elevational gradient; Subarctic; Fertility gradient;

    Abstract : This project investigated how elevation and vegetation type influences variation in plant litter phenolic content and protein precipitation capacity among and within common plant species for two different vegetation types, heath and meadow, in a subarctic ecosystem in the Abisko region of northern Sweden. As nutrient availability generally decreases with increasing elevation as a result of decreasing temperature, I hypothesised that phenolic content would increase with elevation and be higher on the heath than the meadow.

  3. 17. Interferences during analysis of polyphenols in fruit juices

    University essay from SLU/Horticulture (until 121231)

    Author : Jennifer Sandström; [2010]
    Keywords : polyphenols; Folin-Ciocalteu method; total phenolic content; juice; ascorbic acid; fruit juice;

    Abstract : One of the most commonly used methods for analysis of polyphenols is the Folin-Ciocalteu (FC) method, where the FC reagent has been reported to interfere with some substances in fruit juices. The interfering substance that is present in the highest amount in most fruit juices is ascorbic acid. READ MORE

  4. 18. Effects of storage on the visual quality, ascorbic acid and total phenolic content of fresh-cut rutabaga, kohlrabi and parsnip

    University essay from SLU/Horticulture

    Author : Lisa Rydenheim; [2008]
    Keywords : fresh-cut; quality; storage; rutabaga; kohlrabi; parsnip; Brassicaceae; Apiaceae; root vegetables; ascorbic acid; vitamin C; total phenolics; phenolic compounds; enzymatic browning;

    Abstract : The market for minimally processed fruit and vegetables is growing rapidly and root vegetables may be interesting as fresh-cut products. The effect of cutting size and storage time on the quality of the fresh-cut rutabaga, kohlrabi and parsnip was studied. Two different sizes of fresh-cuts were compared; big slices and small sticks.
