面向客户定制需求的产品配置系统

基于客户的定制需求,面向大批量定制环境下的产品设计问题,给出了实现大批量定制的产品设计系统框架结构,并对其中关键技术进行了研究。提出利用面向对象技术进行构件设计,建立基于构件的产品模型和配置流程,利用客户定制需求与零部件构件属性之间的映射关系进行产品配置设计,利用产品模型和客户定制需求建立零部件构件的需求参数,并给出需求参数匹配算法。该系统框架结构和实现方法在农用水泵的配置系统中进行了应用,效果明显。     

发酵法制备竹笋下脚料膳食纤维的研究

通过利用根霉菌发酵过程中消耗糖类和蛋白质的作用,从竹笋下脚料中制备纯度高、品质佳的膳食纤维。正交试验结果表明,原料粉20目,液料比1∶15(g/mL),34℃下发酵32 h可获得品质较好的竹笋膳食纤维,得率达到54.53%,总膳食纤维含量54.2%。与传统化学法相比,微生物发酵法具有原料损失少、得率和可溶性膳食纤维含量高的优点,制备的膳食纤维持油力相近,持水力和溶胀度显著提高。品质测定结果表明,发酵法制备的膳食纤维食用性和功能活性较高,并且保持了竹笋本身特有的风味。根霉发酵条件温和,工艺简单,易于放大,是一种高效制备毛竹笋下脚料膳食纤维的方法。

气调与热风干制对双孢蘑菇片干燥速度与制品质量的影响

以提高双孢蘑菇干制品质量为目的,采用自行设计的小型气调干燥实验设备,用CO2、N2气体置换干燥室空气作为介质对双孢蘑菇片进行气调干制试验。分析了气调与热风干制对双孢蘑菇片干燥速度和制品质量的影响。结果表明:双孢蘑菇片采用充N2降O2干制的干制品维生素C保存率得到较好保存,纤维化进程慢,褐变度低,更接近鲜菇固有的风味和品质。

Water requirements of liquid-fed heavy pigs: Effect of water restriction on growth traits,animal welfare and meat and ham quality

Reducing water waste, and therefore the total volume of manure produced, is one of the ways to lower the environmental impact of intensive pig farming. The aim of this trial was to verify whether the absence of additional fresh drinking water could compromise the production traits or behaviour of liquid-fed heavy pigs. Sixty animals (initial BW 78 kg) were divided into two experimental groups, both fed a liquid diet (water-to-feed ratio 3:1 w/w). All pens were equipped with nipple drinkers; one of the groups had permanent access to fresh water (working drinkers—WD), whereas the other group had no water supply except that delivered with food (dry drinkers—DD). The pigs were housed in temperature- and humidity-controlled rooms. They were brought to a weight of 160 kg and then slaughtered. Hams were dry-cured according to the directives for Parma ham production. No significant differences (P>0.05) were observed between the experimental groups with respect to growth parameters (ADG and FCR), behavioural traits, blood parameters or the qualitative traits of carcasses (dressing out, lean meat yield, backfat thickness), meat (pH, colour, WHC, fatty acid composition of subcutaneous fat and tenderness) and cured hams (weight losses, sensory properties, chemical composition and oxidative status). With respect to drinking behaviour, a low number of visits to the drinker were recorded for both groups and data seem to indicate a high amount of water wasted by pigs provided with additional water delivery by nipple drinkers. Liquid feeding did not suppress drinkers use or drinker manipulation in both groups.
