Zea mays L. Pollen： An Approach to Its Quality Control

Zea mays L. is one of the biggest cropping systems among the sustainable development agronomy. Pollen from this crop source is unexplored and apiculture can be a good partner adding value to the product and creating new jobs helping to solve some social issues as unemployment. However, food safety is crucial, thus the aim of this study was to explore the flavonoid/phenolic profiles from Z. mays L. pollen as a fingerprint for this plant identification and also to demonstrate how the method of bee pollen samples （honeybee collected pollen） is applied. For this purpose, several sources ofZ. mays L. pollen were analyzed, including corn hybrids and genetic modified samples collected at the breeding fields. For this work, samples were taken at several years from 2000 to 2012 and collected from different countries and locations, such as Portugal, Mexico and Brazil. Results showed, for the first time, that the fingerprint （flavonoid/phenolic profile） for Z. mays L. pollen does not change over the time of sampling neither with the region of harvesting. The high performance liquid chromatography-diode array detector （HPLC/DAD） fingerprints of phenolic/flavonoid extract from Z. mays remain unchanged for all samples analyzed from different countries, hybrids and/or genetic modified plants. This is also the first study reporting these phenolic compounds not only in pollen collected directly from hybrid plants, but also in Z. mays bee pollen. The described fingerprinting method is easy, fast and accurate for the characterization of Z. mays L. pollen samples and complete microscopic analysis because it is species-specific.

Three Major Effects and Guarantee System for Quality Management of Edible Mushroom Products

In order to provide consumers with more safe and edible fungus products and to create a faithful social environment of food quality, the edible fungus products quality safety events, as well as their evoked factors and effects on edible fungus industry were discussed in depth in this paper. The performance of edible fungus products quality management is a comprehensive reflection of technical effect, control effect and implementation effect. Among them, the implementation effect is the most important, which refers to the actual implementation effect of quality and safety rules by practitioners of edible fungus industry. Thus, the initiative implementation effect in quality management will be improved, and a quality assurance system in which practitioners are volunteered to participate and implement initiatively the quality standards and regulations so as to provide safe and high-quality products will be established, thereby achieving the best actual implementation effect in quality management.
