Methods: 1.Washing celery and dividing it into two parts, namely stems and leaves. Then each part will be made separately the juice and the dregs with the wringer, after two parts of celery juice have be evaporated by revolving evaporation instrument, collects its extracts. After two parts of celery dregs have be extracted by ethyl alcohol, collects its extraction.

The ultrafilteration is applied in the separation and concentration of the zymin, it can be operated in the normal temperatures, overcome the effects heat does to the quality of the fermented products, abstract small molecular admixtures, and guarantees filtrates purity and quality; Filtering process does not change, the energy consumption and the cost compared with the traditional method are lower; The equipment running is simple, and is easy to operate and the control, thus it quickly became concentration separation craft the first choice of concentration separation such as biology medicine manufacture.

现在采用超滤技术进行酶制剂的分离浓缩，则可在常温下操作，克服热对发酵产品品质的影响；除去其中的小分子杂质，保证滤液的纯净度和品质的良好性；过滤过程无相变，能耗和成本较传统方法都低；设备运行简便，易于操作和控制，因而很快成为了生物制药等行业分离浓缩工艺的首选。

Results showed that all the three sweet sorghum varieties contained plentiful sugar, which can provide enough carbon source for alcohol fermentation, however, total nitrogen and some mineral elements（Fe3＋）cannot meet the needs of alcohol fermentation. Activity of most microbes in stalk juice can be inhibited and the sugar can be maintained when the stalk juice was condensed to 4～5 times. Due to the reasons that the activity of acetous microbe or hydrolysis enzyme inside stalk juice can be maintained, ratio of reducing sugar to total sugar was increased with storage time at 55～60℃,0.15 MPa vacuum condensed condition, which can be beneficial for the purpose of alcohol fermentation.

结果表明，三个品种都含有丰富的糖分，可以为酵母菌发酵制取酒精提供良好的碳源，但总氮和某些矿物质元素（如：Fe3＋）不能满足酒精酵母的营养需要；甜高粱茎秆汁浓缩至4～5倍时，可以抑制汁液中大多数微生物的活动，使其中糖分不受损失；在试验设定的真空浓缩工艺条件下（55～60℃，0.15 MPa）甜高粱茎秆汁中产酸微生物或水解酶类仍保持活性，使得还原糖占总糖的比率随贮藏时间延长而升高，这有利于酒精发酵。

The experimental results show that: lithium is scatteredly precipitated as natural lithium carbonate in the whole evaporation process, and the highest content of natural lithium carbonate in solid phase is 2.0%, so it is difficult to get the mixed salt with high-grade lithium carbonate; boron is precipitated as borax in the whole evaporation process, and borax is precipitated in large quantity with the highest content of 15.64% in solid phase until the brine is extremely concentrated (CWR≥97.9%) and intergrows closely with typical cold-phase natron; potassium is precipitated as sylvite and aphthitalite in the whole evaporation process with a content from 9.49% to 34.44%.

结果表明：在低温蒸发状态下，锂以天然碳酸锂形式在整个蒸发过程中分散沉淀，固相最高含量仅达2.0%，因此难以获得较高品位的富锂混盐；硼在全蒸发过程中以硼砂形式自然沉淀。当卤水高度浓缩（蒸失率达97.9%以上）时大量析出并与典型冷相矿物泡碱紧密共生，固相中硼砂含量最高可达15.64%；钾以氯化钾和钾芒硝形式沉淀，在蒸发浓缩的全过程中均有不同程度析出，固相含量在9.49%~34.44%之间波动。

We extract the lipid with hexane and then compare the removing effect of 20% trichoroacetic acid and 2.0mol/L chlorhydric acid after having condensed the extract.

将提取液浓缩后，利用正己烷萃取提取液中的脂溶性物质，然后分别测定在浓缩物中加入不同体积的20％的三氯乙酸及2mol／L的盐酸的除蛋白效果，结果显示盐酸为较佳的除蛋白试剂。

The clavacin toxin generally exists in the concentrated apple-juice for export, especially in the middle and later period of the squeezing season, the risk the content of the clavacin toxin exceeds the standard is very big in the case that the decay ratio of the raw material of the apple is higher. In the practical examination and verification of HACCP food safety management system, people found various methods and paths for controlling the clavacin toxin in the production of the concentrated apple-juice, b...

棒曲霉毒素在出口浓缩苹果汁中普遍存在，特别是在榨季的中后期原料苹果的腐烂率较高时其质量分数超标的风险很大，在HACCP食品安全管理体系审核实践中，发现浓缩苹果汁生产过程中，控制棒曲霉毒素的方法和途径有多种，但不论哪一种或多种组合应用都应关注原料果的品种、生产季节和储存温度，因为这些因素是降低棒曲霉毒素质量分数和生产成本的关键因素。
