本试验采用HPLC法对纯生啤酒中蔗糖转化酶活性进行了定量分析。对市售不同品牌8度纯生啤酒的蔗糖转化酶活性进行了连续四个月的检测,市场上三个月货架期的纯生啤酒蔗糖转化酶活性水平有较大差异,最低0.24×10^-4,最高1.68×10^-4U。同时进行了温瓶试验,并实际取样评价了生产上温瓶工艺对蔗糖转化酶活性的影响。温瓶工艺对蔗糖转化酶活性影响较大,是蔗糖转化酶活力降低的关键因素。并进行了消费周期对蔗糖转化酶活性的影响研究,蔗糖转化酶的活性随着消费周期的延长逐渐降低。 相似文献

Dielectric properties of honey adulterated with sucrose syrup 总被引:2,自引:0,他引:2
Sucrose syrup is a common additive in honey adulteration. To provide information for developing a cheap, simple, convenient and rapid sucrose-adulterated honey detector or sucrose content sensor, the permittivities of pure jujube, yellow-locust and milk-vetch flower honey, pure sucrose syrup and honey-sucrose syrup mixtures with sucrose content from 0% (pure honey) to 80% (pure sucrose syrup) were studied from 10 to 4500 MHz with open-ended coaxial-line technology and a network analyzer at room temperature. The correlations between permittivities and sucrose contents were regressed. The results showed that the dielectric constants of all samples decreased with increasing frequency, while the pure honey had higher dielectric constant than pure sucrose syrup. Dielectric relaxation existed in all samples. The maximum loss factor decreased with increasing sucrose content. The relaxation frequency changed very little with sucrose content. Strong negative linear correlation, R2 > 0.98, was found between loss factor around the relaxation frequency and sucrose content. 相似文献

Sucrose fatty acid esters of various hydrophilic-lipophilic balance (HLB) values were found to improve cake volume and softness as HLB increased. When present in high concentrations (1.0-2.0% total flour wt basis), however, the sucrose ester emulsifiers caused drastic changes in surface appearance and in cake symmetry. Visual observations, amylograph data, and microscopic studies indicated that the sucrose esters delayed the pasting and gelatinization of the starch granules. There did not appear to be any synergistic effects of the sucrose esters when blended with a commercial alpha-mono/diglyceride emulsifier. 相似文献

Sucrose esters of varying hydrophilic-lipophilic balance (HLB) values were added to standard ice cream mixes at 0.15 or 0.25%, and compared with ice creams containing either a commercially available or no emulsifier. Resulting viscosities and overrun patterns were similar, but surface tensions decreased with increasing HLB and concentration. The addition of sucrose esters at 0.25% tended to prevent clumping out of fat particles. Sucrose ester-containing samples melted in a normal manner, and only texture differences were detectable among samples, with the ester-containing samples rated higher than the control or reference samples initially and similar to the reference after storage. 相似文献
