Polyphenol oxidase activity and colour changes of peeled potato (cv. Monalisa) in vacuum
Minimal processing of vegetables has some undesirable physiological consequences. The shelf life of peeled raw potatoes is limited by the onset of enzymatic browning at the cut surfaces. It is generally accepted that polyphenol oxidase (PPO) is the enzyme mainly responsible for this type of browning. This work aimed to study the effect of vacuum storage at 4?C on the colour, which is the main ...

Response to host plant odors and aggregation pheromone by larvae of the Colorado potato beetle on a servosphere
Using a servosphere (locomotion compensator), locomotory behavior of Colorado potato beetle Leptinotarsa decemlineata Say (Coleoptera: Chrysomelidae) larvae was measured in detail in response to pulsed and non-pulsed odors of hostplant and conspecific pheromone. Second instars showed decreased straightness of movement, and all larvae showed decreased speed, in response to potato odor. Change in ...

Fresh growers achieve market-ready results with 1,4SIGHT® and 1,4Zap®
There are two treatments for stored potatoes from which fresh growers are seeing year-after-year effectiveness. Well-timed applications of 1,4SIGHT® or 1,4ZAP® demonstrate results that help growers get the most out of their stored spuds, like reduced load rejection. The two different applications can be implemented in the spring and early summer, and are timed strategically in close ...

Organic production: the adoption of a niche strategy by the mainstream food system
This paper critically assesses the potential and barriers for food system transformation from the conventional to an organic model by utilising the literature on system innovation. Based on the analysis of two food supply chains in the UK, namely chicken and potato production and processing, the paper demonstrates that the current conventional food system appears to be resilient to radical ...

Second generation European corn borer injury and Irish potato physiology, yield, and quality
European corn borer (ECB) [Ostrinia nubilalis (Hübner)] (Lepidoptera: Crambidae) is known to infest Irish potato (Solanum tuberosum L.) but only causes economic damage during the first generation in East Coast potato producing areas. However, in Nebraska, second generation ECB infest potato plants during the bulking period and may reduce yield and/or potato quality. Experiments were conducted in ...

Potato Salad Manufacturer
The manufacturing of potato salad creates a high BOD and Fats, Oil & Grease wastewater that was costing over $6,000/month in surcharges to treat by the local POTW. The facility investigated the use of the Floccin product and found that Floccin-H removed over 90% of the TSS and 80% of the BOD, thereby decreasing the surcharges to the POTW from $6,000/month to $1,500/month. The facility treats ...

Research on microbial lipid production from potato starch wastewater as culture medium by
Lipomyces starkeyi In this paper, potato starch wastewater as culture medium was treated by the oleaginous yeast Lipomyces starkeyi to biosynthesize microbial lipid. The result indicated that carbon source types, carbon source concentration, nitrogen source types, nitrogen source concentration, inoculum size, and cultivation time all had a significant effect on cell growth and microbial lipid accumulation in ...

Seasonal slug pressure warning – crops at greater risk
Crops face a greater risk of slug damage and if left untreated, this can become extremely expensive for farmers, and is estimated to cost the potato industry up to £53 million per year*, as any slug damage reduces saleability and ultimately profitability of a crop. Slugs are most damaging to potatoes during the early stages of tuber bulking, which is starting to happen now. So make sure ...
