The price pricking beer is 3 5 times higher than familiar equal amounts beer , investigates whose cause to have several aspect down: One, has been fresh beer because of it , has kept fine taste of beer and nutrition; That sterile condition demands is strict among it's two , procedure of production, equipment investment is big, be going to want the strict sterility course film fliteration or hole fliteration, besides all microorganism , beer barrel and production environment before irrigating dress; It's three , marketing way have been unique , had been going carrying out the carbon dioxide cooling down and supplementing by the fact that fresh beer sells machine, have made use of carbon dioxide pressure to give beer and , have avoided beer contacting air but have produced oxide taste; It's four, has been that scheduled time is not long because of barrelled fresh beer guarantee quality , the dealer has born certain risk, if being able to not sell out in time, meeting bring about very big economic losses.

扎啤的价格比同等量的熟啤酒高3—5倍，究其原因以有下几个方面：其一，因为它是鲜啤酒，保持了啤酒良好的口味和营养；其二，生产过程中，无菌条件要求严格，设备投资大，在灌装前要经过膜过滤或孔过滤，除去所有的微生物，啤酒桶和生产环境也要严格无菌；其三，销售方式独特，要过通过鲜啤酒销售机进行降温和补充二氧化碳，并利用二氧化碳压送啤酒，避免了啤酒接触空气而产生氧化味；其四，是因为桶装鲜啤酒的保质期不长，经销商承担了一定的风险，如果不能及时售出，会造成很大的经济损失。

The values of D10 and D for the total bacteria in boiled dumplings under chill state were 2.04 kGy and 4.00 kGy, the value of D10 and D for E. coli were 1.25 kGy and 2.00 kGy. TBAS were increased significantly and excessed the trade standard by 5 kGy γ-irradiation. However, the TBAS would be decreased with addition of antioxidants. Lipid peroxide,volatile basic nitrogen,"a" value of color and "b" value of color showed a tendency of increase, and moisture content and Aw showed a tendency of decrease, which did not achieve a significant level(p.05) by 1 to 5 kGy doses of γ-irradiation. Total acidity, amino acid nitrogen and free fatty acid showed no significant differences between treated and control samples. Sensory evaluation values were decreased and were all well within the acceptable level by 1 to 5 kGy doses of γ- irradiation.

辐照能有效降低鲜熟水饺细菌总数和大肠菌群数量，鲜熟水饺中细菌总数和大肠菌群的 D10值分别为 2.04 kGy 和 1.25kGy，D 值分别为 4.00 kGy 和 2.00kGy；0～5kGy 辐照鲜熟水饺 TBA 值随辐照剂量增加而增加，5kGy 辐照已使之超过国家行业标准限量要求；辐照鲜熟水饺过氧化值、挥发性盐基氮、色差 a 值、色差 b值存在随辐照剂量增加而增加的趋势、水分含量存在下降趋势，但变化未达到显著水平(p.05)；对酸度、氨基酸态氮、水分活度、游离脂肪酸含量等其他理化指标没有显著影响；较高剂量辐照使产品感官质量降低，却都在可接受范围内； 4kGy 辐照使维生素 B1下降 31.94%，对维生素 E、蛋白、脂肪、氨基酸、不饱和脂肪酸含量无显著影响。
