Production Areas

Citric acid and potassium contents were determined for Russet Burbank tubers collected from the major production areas in Alberta. An increase in the ratio of citric to chlorogenic acid content is known to be associated with a decrease in the tendency for potato tubers to darken after cooking. Tuber citric acid and potassium contents were higher in southerly locations than in central locations. The trend for citric acid is the reverse of that for chlorogenic acid established in a previous study. Thus, potatoes grown at southern Alberta locations have a higher citric to chlorogenic acid ratio than those grown in central locations, suggesting that they would be less subject to after-cooking darkening.Key words: Darkening (after-cooking), citric acid, chlorogenic acid, potassium content, Russet Burbank, potato

Seeding Date

The effect of seeding date on the chlorogenic acid content of sunflower seed flour was determined by seeding the cultivars Krasnodarets and Peredovik at seven dates, starting on 14 May, over 3 yr. Sequential plantings were made at increments of approximately 70 growing degree days (base = 5.6 C). Plants were harvested at normal field maturity. The time and rate of deposition of chlorogenic acid was determined by harvesting plants at 7-day intervals from 21 to 49 days after flowering. The seeds were dehulled and defatted before determining the chlorogenic acid content of the flour. Chlorogenic acid content declined steadily from an average of 4.22% for the first seeding to 3.30% for the last seeding. About one-half of the total chlorogenic acid was present 21 days after flowering. Deposition continued rapidly for the next 14 days then the level began to stabilize. Delay in seeding tended to shorten the period of vegetative growth and shift the deposition of chlorogenic acid to a cooler portion of the growing season. It is suggested that a combination of these factors caused the reduction in chlorogenic acid content of sunflower flour.

The Relationship

The study of microbes associated with the coffee tree has been gaining strength in recent years. In this work, we compared the leaf mycobiome of the traditional crop Coffea arabica with wild species Coffea racemosa and Coffea stenophylla using ITS sequencing for qualitative information and real-time PCR for quantitative information, seeking to relate the mycobiomes with the content of caffeine and chlorogenic acid in leaves. Dothideomycetes, Wallemiomycetes, and Tremellomycetes are the dominant classes of fungi. The core leaf mycobiome among the three Coffea species is formed by Hannaella, Cladosporium, Cryptococcus, Erythrobasidium, and Alternaria. A network analysis showed that Phoma, an important C. arabica pathogen, is negatively related to six fungal species present in C. racemosa and C. stenophylla and absent in C. arabica. Finally, C. arabica have more than 35 times the concentration of caffeine and 2.5 times the concentration of chlorogenic acid than C. stenophylla and C. racemosa. The relationship between caffeine/chlorogenic acid content, the leaf mycobiome, and genotype pathogen resistance is discussed.

Term Storage

In three-year field experiments, the effect of genotype, flesh color, site conditions and storage on chlorogenic acid content (CAC) in tubers of potato cultivars with purple or red flesh was compared to yellow-fleshed cv. Agria. The results confirmed the significant effect of genotype on CAC. The highest CAC was characteristic on a three-year mean for the purple-fleshed cv. Vitelotte (769.5 mg/kg fresh weight (FW)), i.e. 1.19−2.6 times higher than in the other cultivars. In regard to the effect of flesh color, significantly higher mean CAC levels have been shown for the red-fleshed (2.8 times) and purple-fleshed (3.16 times) cultivars in comparison with cv. Agria (148 mg/kg FW). At the Uhříněves location with a warmer climate and frequent dry periods as compared to the second Valečov location, a higher CAC (1.18 times) was found. Cold storage (4°C, 6 months) resulted in a significant CAC increase varying from 33.2% in the Blaue St. Galler cultivar to 210.6% in the Vitelotte cultivar among all eight evaluated color-fleshed cultivars. On the other hand, the effect of storage on CAC was not evident in the yellow-fleshed Agria cultivar (inconclusive difference against CAC after harvest).
