摘要

采用Box-Behnken设计，研究温度、热处理时间和NaCl浓度对金毛竹笋中氢氰酸(HCN)含量的影响。共进行了15个不同因素组合的处理。对桂格纳苦味酸钠的定性分光光度法进行了改进，以定量测定HCN。建立了二次型高相关曲线(R2=0.965)，可定量测定各处理的含量。样品中HCN的最终浓度在0.007 ~ 0.015 mg/mL之间。在测试的因素中，只有热处理温度和时间对HCN的还原有显著影响。最后，建立等高线图，以确定最显著降低HCN的最佳处理条件。

REDUCTION OF CYANIDE CONTENT IN PHYLOSTACHIS AUREA BAMBOO SHOOTS: OPTIMIZING THE PROCESSING CONDITIONS OF TEMPERATURE, HEATING TIME, AND NaCl CONCENTRATION

A Box-Behnken design was applied to evaluate the impact of temperature, heat treatment time, and NaCl concentration on the hydrocyanic acid (HCN) content in bamboo shoots of the Phyllostachys aurea species. A total of fifteen treatments with different combinations of the factors were carried out. For the quantification of HCN, a modification of the qualitative spectrophotometric technique of Guignard sodium picrate was followed. A calibration curve was constructed, which showed a quadratic form and high correlation (R2=0.965), and the resulting equation allowed quantifying the content of each of the treatments. The final concentration of HCN in samples was found to be between 0.007 and 0.015 mg/mL. Among the factors tested, only the temperature and time of heat treatment showed a significant impact on the reduction of HCN. Finally, contour plots were build up in order to identify the optimal treatment conditions for the most significant HCN reduction.

期刊介绍： AGROCIENCIA is a scientific journal created and sponsored by the Colegio de Postgraduados. Its main objective is the publication and diffusion of agricultural, animal and forestry sciences research results from mexican and foreign scientists. All contributions are peer reviewed. Starting in the year 2000, AGROCIENCIA became a bimonthly and fully bilingual journal (Spanish and English versions in the same issue). Since 2007 appears every month and a half (eight issues per year). In addition to the printed issues, the full content is available in electronic format.
