查询词典 acid value

As we all know, acid value is one of the most important parameters to indicate the quality of meat, so can anyone tell me how to do the experiment of acid value?

In this research,the indexes relating to the quality of the fried oil,including the content of the ploymers,acid value,iodine value,saponification value,peroxide value,the content of the diglyceride,oxidation stability,viscosity,were detected.The results showed that with the frying time prolonging,the content of the polymers and viscosity increased greatly,iodine value and saponification value decreased,peroxide value and acid value increased,and the content of unsaturated fatty acid reduced,a little of diglyceride produced.

在食用油煎炸过程中，对油脂品质相关的指标(包括酸值、碘值、皂化值、过氧化值、脂肪酸组成、氧化稳定性、黏度、聚合物的含量以及甘一酯、甘二酯和甘三酯的含量)进行检测，结果表明，随着煎炸时间的延长，煎炸油中的聚合物含量大大升高，黏度增大，有少量甘二酯生成，不饱和脂肪酸含量下降，碘值、皂化值降低，酸值、过氧化值升高。

Whole grain adlay and dehulled kernels stored at room temperature ( about 25℃), 15℃ and 5℃ were used as raw materials. Completed random design and factorial experimental design were adopted to analyze the changes of coixenolide content, fatty acid distribution and physicochemical properties ( including acid value and peroxide value ) of the adlay oil extracted from the materials in order to find more suitable storage condition.

摘要本研究探讨薏苡籽实，以带壳状态和脱壳后的糙薏仁粒分别贮存於常温(约25℃)，15℃及 5℃之下，利用 CRD 和复因子试验设计定期取样分析籽实在贮藏六个月期间薏仁油中薏仁酯含量，脂肪酸组成，以及薏仁油理化特性之变化，以期找寻薏苡籽实的较适贮存条件。

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

通过样品外观的观察初步定性是否掺有杂质；利用纯蜂蜡在苯中溶解，而掺入的石膏、面粉和淀粉等杂质在苯中不溶而定量鉴定这类杂质；由酸值变化和乙醇溶解物的量，测定掺入的硬脂酸等酸性物质或其它的非酸性物质；由皂化值变化，定量测定掺入的动物脂等酯类物质或其它的非酯类物质；根据蜂蜡中的烃类在浓硫酸中可被炭化，加入的石蜡等矿物蜡不被炭化来测定此类掺杂物。

After 3 months storage, our result showed that (1) color a value of rose liqueur with sucrose treatment had a slower decreased than with fructose treatment,(2) the sample added with caffeic acid or ferulic acid or tea polyphenol showed no significant difference in the color, anthocyanins content, and antioxidant capacity during storage as compared to control, and (3) the total amount of volatile compounds of rose liqueur decreased gradually, however there was one ester volatile formed, hexadecanoic ethyl ester, during storage.

贮藏三个月发现，(1)以果糖勾兑者在储藏试验中，其红色度下降速度较以蔗糖处理者快，建议仍以非还原糖进行勾兑对日后酒液保存较易，且酒液最好能予以避光包装，以避免颜色品质的下降；(2)添加不同之多酚类化合物时发现，添加caffeic acid、ferulic acid和茶多酚对酒液色泽、花青素含量、以及抗氧化能力之降低速度与控制组并无显著性的差异。(3)酒液储藏三个月后，其香气高级醇均有减少之趋势；但有hexadecanoic acid， ethyl ester酯类出现。

Two-component waterborne polyurethane paint composed of acrylic dispersion and hydrophilically-modified polyisocyanate has fast dry time, good adhesion, flexibility, impact resistance, but poor water and chemical-resistance. The dry time becomes shorter with the increase of glass transition temperature and the decrease of acid value; the gloss of the film decreases with the increases of hydroxyl value, acid value and Tg of emulsion polymer; higher Tg polymer leads to harder film.

将制得的丙烯酸分散体与亲水改性多异氰酸酯组分配制水性双组分聚氨酯涂料，发现漆膜表干和实干比较快，干燥时间随玻璃化温度升高而缩短，随酸值的增加而增加；附着力、柔韧性和冲击强度比较好；光泽随分散体羟值、酸值的增加和玻璃化温度升高而降低；硬度随玻璃化温度升高而升高；较高的酸值使涂料的耐化学品性和耐水性较差，羟值在100mgKOH/g时较好，而酸值应尽可能低。

Their contents, refractive index, specific gravity, saponification value, acid value, and iodine value were examined. The quantilative determination of fatty acid was also made by means of GLC.

根据分析结果，本文着重讨论了在菊科、安息香料、木樨科、茶科、樟科和藤黄科油脂植物中各种常见的饱和脂肪酸和不饱和脂肪酸的含量及其利用价值。

According to the analysis of rubber seed oil, C16 and C18 were the main fatty acid components, acid value was 38.836mg/g, saponification value 198.784mg/g, iodine value 122.092g/g and it belonged to semi-dry oil.

通过对橡胶籽油的部分理化参数分析表明：橡胶籽油以C16和C18为主，酸值为38.836，皂化值为198.784，碘值为122.092，属半干性油。

Unsaturated fatty acidcontents of fat were 64.80%,fatty chemical Characteristic : iodin value 70.86 ,acid value 0.4933 ,saponification number 195.34 ,The conclusion indicated that the raised Landaise geese had better animal meat material,concluding: abundant flavor substance and essential amino acid,lower fat content and higher Unsaturated fatty acid.

脂肪中不饱和脂肪酸含量高达64.80%，脂肪酸碘价70.86 ，酸价0.4933，皂化价195.34。由此可知：朗德鹅具有较好的肉用性能，尤其是朗德鹅肌肉富含风味物质、必需氨基酸和大量的不饱和脂肪酸，是人类较好的动物肉食原料。中图分类号： TS201.2 ； TS251.1 文献标识码： A
