Temperature and humidity storage conditions on the characteristics of yellow Participation

Scientific basis for, especially for the study. 1 Materials and methods 1.1 Material parameters for the test yellow collected from April 1999 Shandan County, woven bags, packaging, automotive arrived in Lanzhou into the meat processing temperature cold storage, at O ℃, 70% relative humidity storage stand . 1.2 1.2.1 temperature processing equipment 0 ℃, 5 ℃,[link widoczny dla zalogowanych], 10 ℃ and 18 ℃ 4 different temperatures processing, each processing parameter 20 in yellow, repeat 3 times. 1.2.2 0.03mm thick humidity treatment into low density polyethylene perforated film bag for high humidity treatment, the relative humidity bag 9o% ~ 95%; to not be repackaged for the low humidity treatment, Rtt70% ~ 75% . 1.2.3co = and ethylene production was determined by Slli. matzuGc a 9A gas chromatography. c () 2 was determined by 3mmXlm stainless steel column with activated carbon as stationary phase, detector TCD. Ethylene was determined by 3mmX2m stainless steel column, stationary phase GDXS02, detector FID. Repeat each measurement 3 times the average. 1.2.4 weight loss rate was determined by gravimetric method. 1.2.5 Statistical germination percentage method used. 1.2.6 Statistical decay rate by a percentage method. 1.2.7 Main rot pathogens isolated and identified with reference to the prescription of law .... 2 Results and discussion 2.1 reference storage temperature conditions on the yellow respiration and ethylene production during the impact of a 49 - its production was inhibited (Figure 1). During storage lO ℃ and 18 ~ C temperature treatment were respiration rate gradually increased, while the 0 ℃ 5 ℃ handlers and respiration rate decreased, but significantly higher in the later storage. The increased respiration may be extended with the pathogen causing invasive respiratory related injuries. Huang participation is very low ethylene production during storage, in addition to 0 ℃ deal were not detected, the other temperatures were lower than 0.1HI/kg · h, and no significant variation. {O As the temperature increased, the weight loss during storage Huang participation rate also increased significantly (Figure 2). With perforated plastic film packaging caused by high humidity conditions can significantly reduce post-harvest yellow weight loss rate parameters, the harvest was only 30d did not use the weight loss treatment package humidity 28% to 40%. Since the barrier packaging, the internal vapor pressure generated a high, yellow ginseng, significantly inhibited transpiration will 【2]. l168I1241o: 240 ring. . . Figure 2 different treatment temperature, humidity, storage under the conditions of participation in weight loss 30d 2.3 yellow temperature and humidity conditions during storage on germination rate of participation yellow shadow of a 5O a bright yellow at low temperature can inhibit the germination of the postharvest parameters, with the temperature increased, the yellow ginseng significantly increased the germination rate (Figure 3). Huang parameters during storage is normal in post-harvest sprouting growth. Therefore, people cut out yellow storage parameters before the growing point or use the top of the growth regulators on germination can be effectively controlled. 4O35-3O25 flap 0. ''. 5O treatment Figure 3 different temperatures,[link widoczny dla zalogowanych], humidity 30d yellow storage the germination rate of 2.4 parameters of temperature and humidity conditions on the decay rate of participation yellow as the temperature increases the decay rate of yellow marked increase in participation, high humidity can accelerate the decay parameter Huang (Figure 4). Participation in the yellow rot diseases caused by species of Penicillium diseases caused by Penicillium the most common, accounting for the total decay rate of 6o% ~ 70%. High-temperature treatment to the most common soft rot caused by Mucor. Two pathogens can invade the host through a wound, and possess the ability to contact with infected H]. 1008O hesitate 6O Revealed 402OO0 ℃ 5 ℃ lO ℃ l8 ℃ treatment Figure 4 different temperature, storage temperature, the decay rate of participation 30d Huang [1] Fang up.
