脱脂乳粉

脱脂乳粉作为一种含有非晶态组分的食品粉体，其结块现象必须通过基于非晶态高聚物玻璃化转变的结块机理来解释。

The skim milk powder is a kind of food powder containing amorphous components and its caking behavior has to be explained with the caking mechanism based on the glass transition of the amorphous polymer powder .

脱脂乳粉应在较低水分活度（例如0.3以下）和较低温度（例如40℃以下）下贮藏，以延长其货架寿命。

The skim milk powder should be stored under the conditions of low water activity ( e.g. less than 0.3 ) and low temperature ( e.g. below 40 ℃) in order to prolong its shelf life .

结果表明：随着水分活度、贮藏温度、贮藏时间以及贮藏温度T与脱脂乳粉的玻璃化转变温度Tg间的差值（T-Tg）的增加，脱脂乳粉非酶褐变指数显著增大；

The results showed that the non-enzymatic browning indexes markedly increased with the increase of water activity , storage temperature , storage time and ( T-Tg ) .

结果表明：在较低的（T-Tg）时脱脂乳粉的非酶褐变指数较小，但随着（T-Tg）的增加，非酶褐变指数会迅速增加。

The results showed that the index of non-enzymatic browning of skim-milk powder was low at small T-Tg , but it increased sharply with the value of ( T-Tg ) .
