【摘要】：目的研究亞臨界載荷對(duì)蘋果呼吸速率變化的影響機(jī)制。方法首先通過(guò)在跌落臨界高度以下設(shè)置不同高度的蘋果跌落實(shí)驗(yàn);然后測(cè)量跌落后的蘋果在密封容器內(nèi)CO2和O2濃度的變化;最后根據(jù)實(shí)驗(yàn)數(shù)據(jù)得到跌落高度與蘋果呼吸速率的關(guān)系。結(jié)果在亞臨界高度下,蘋果受到損傷沖擊后的呼吸速率發(fā)生了較大變化。在相同的時(shí)間內(nèi),跌落高度越高,密閉容器中O2的含量越少,CO2的含量越多,呼吸速率越大。隨著跌落高度的增加,氧氣的減少率越來(lái)越大,二氧化碳的增加率也越來(lái)越大。在同一跌落高度下,隨著時(shí)間的增加,蘋果的呼吸速率逐漸減小,當(dāng)達(dá)到一定時(shí)間后,呼吸速率趨于平穩(wěn)。根據(jù)實(shí)驗(yàn)數(shù)據(jù)建立了亞臨界載荷下呼吸速率與跌落高度和時(shí)間的數(shù)學(xué)模型。結(jié)論研究結(jié)果有助于果品緩沖包裝的改進(jìn)。
[Abstract]:Objective to study the effects of subcritical loading on respiration rate of apple. Methods the experiment of apple drop at different height below the critical height of drop was carried out, and then the changes of CO2 and O2 concentration in sealed container were measured. Finally, according to the experimental data, the relationship between the fall height and the respiration rate of apple was obtained. Results under the subcritical height, the respiration rate of apple was changed greatly after injury. At the same time, the higher the fall height, the less O _ 2 content, the more CO2 content and the higher respiration rate. With the increase of drop height, the decrease rate of oxygen and carbon dioxide are increasing. At the same fall height, with the increase of time, the respiration rate of apple decreased gradually, and when it reached a certain time, the respiration rate tended to be stable. Based on the experimental data, a mathematical model of respiration rate, fall height and time under subcritical load was established. Conclusion the results are helpful to improve the cushioning package of fruit.
