The higher acidity in fruits compared with grapes was one of the main obstacles to producing high-quality fruit wines. In the present research, the effect of the split batch fermentation pattern on the metabolites of greengage wines was investigated. This fermentation pattern included whole fruit immersion in the sucrose and coculturing Saccharomyces bayanus Y4 with Torulaspora delbrueckii Y7. These results showed that the contents of total acidity and dominant organic acids were significantly reduced among the batches. Aliphatic compounds were decreased with the batches, while aromatic compounds that contributed to flavor improvement were increased oppositely. The acetate esters, ketones, and terpenes contents were significantly increased in the first batch of coculture. In addition, acidic stress largely affected the kinetics characteristics of greengage wine on a pilot scale. Interestingly, the increment of total acidity was closely associated with the rate of total sugar consumption, which was affected by microbial activities. The acidity content was significantly declined and distinct flavour profiles were formed in split batch and coculture fermentation of greengage wines. It provides a new avenue to enhance the flavor and quality of fruit wines.

This paper studies the development trend of intelligent mobile phone, confirmed the necessity of research on intelligent mobile phone malicious code. Study on the detection technology, proposed intelligent mobile phone regular networks and random networks based on malicious code propagation model, propagation mechanism is studied. Set up a perfect malicious code discovery and defense system model, at different levels is put forward that different, prove the necessity of scanning algorithm and Semantic Detection Algorithm for eigenvalue. To improve the security of the whole communication network. OverviewAlthough the harm of intelligent mobile phone malware is not very serious, but relates to personal data and the issues of cost, but with the increasing proportion of data services, intelligent mobile phone platform to the operation of the PC machine platform, if we do not timely malicious code found and defense method, intelligent mobile phone malware will affect the whole communication network security. Therefore, we need to come up with the perfect solution to the problem of intelligent mobile phone malicious code. Discovery technologyAt present, the intelligent mobile phone common malicious code found methods mainly refer to PC malicious code analysis techniques. On the current situation, modern intelligent mobile phone antivirus product basically can achieve efficient real-time scanning monitor, killing the virus, update the virus database, its basic communication equipment related to the increasingly approaching perfection. But previous antivirus means basically is based on signature scanning technology, this technology has many advantages, but for unknown malicious code is incapable of action, and that means more passive defense 【1-2】
