    • 摘要: 为了探究油料品质及制油工艺对花生毛油中邻苯二甲酸酯类塑化剂(phthalatic acid esters,PAEs)的影响规律,对未脱皮花生仁和脱皮花生仁分别采用压榨法和浸出法提取花生毛油,对未脱皮和脱皮花生仁及其对应毛油中PAEs含量进行检测分析,研究原料品质和制油工艺对花生毛油中PAEs含量的影响.结果表明:未脱皮和脱皮花生仁中均含有PAEs且在制油过程向毛油中迁移和富集,在不同制油工艺中迁移率的差别致使不同毛油中PAEs含量也有明显差别.7个未脱皮花生仁样品中邻苯二甲酸二丁酯(dibutyl phthalate,DBP)、邻苯二甲酸二(2-乙基)己酯(di(2-ethtlhexyl)phthalate,DEHP)、邻苯二甲酸二异壬酯(diisononyl ortho-phthalate,DINP)和8种塑化剂总的(total content of 8 PAEs,∑8PAEs)质量分数分别为0.085~0.540、0.325~1.372、0.422~0.771和0.964~3.403 mg/kg.花生浸出毛油中DBP、DEHP、DINP及∑8PAEs平均含量是压榨毛油的1.39、1.23、1.16、1.22倍.花生仁脱皮制油可使毛油中DBP、DEHP、DINP、∑8PAEs含量分别降低33.0%~36.4%、26.7%~29.4%、15.0%~18.7%、22.5%~23.0%.在花生油生产尤其是炒香型花生油生产时,严格对花生仁原料中PAEs含量进行监控,同时采用花生脱皮压榨取油,对花生油产品的PAEs风险防范和控制有重要意义.研究结果可为企业生产高品质花生油,降低PAEs风险提供参考.%Phthalatic acid esters (PAEs) are one of the major risk components in edible vegetable oil. Peanut is the advantageous oil crop in China, and its output ranks the forefront in the world. Peanut oil is also the traditional high-end edible oil, and especially the majority of consumers enjoy the fragrant peanut oil because of its unique flavor. However, the study on the content of PAEs in peanut and its effect on the content of PAEs in peanut oil was very scarce. In this paper, the peanut raw material in different peanut producing areas was collected and peeled, and the contents of PAEs in peanut kernel, peanut coat and peeled peanut kernel were measured respectively. Then the peanut crude oils were obtained from peanut kernel or peeled peanut kernel by solvent extraction or pressing. The content of PAEs in peanut raw material and its corresponding crude oil were tested and analyzed, and in addition, the effects of raw material quality and oil production on the content of PAEs in peanut crude oil were explored. The results showed that PAEs were determined in all peanut materials, nevertheless, the distribution of PAEs in peanut was uneven, and the PAEs content in peanut coat was significantly higher than that in its corresponding peeled kernel and whole oilseed. The contents of dibutyl phthalate (DBP), di (2-ethtlhexyl) phthalate (DEHP), diisononyl ortho-phthalate (DINP) and the total content of 8 PAEs (Σ8PAEs) in 7 peanut samples were 0.085-0.540, 0.325-1.372, 0.422-0.771 and 0.964-3.403 mg/kg, respectively, while theΣ8PAEs content in peanut coat was 1.15-19.21 times that of peanut kernel. The PAEs in peanut would migrate and be enriched in crude oils during the process of oil production, what was more, the PAEs contents in peanut crude oil were different with different peanut raw material and processing techniques. The migration rate of the PAEs in solvent-extracted crude oil was greater than that of the pressed crude oil. For example, the average contents of DBP, DEHP, DINP andΣ8PAEs in peanut solvent-extracted crude oils were 1.39, 1.23, 1.16, and 1.22 times that of the pressed crude oils, respectively. For crude oil obtained from peanuts after peeling, the exposure risk of PAEs was lower than the oil obtained from peanut without peeling. For example, the contents of DBP, DEHP, DINP andΣ8PAEs in peeled peanut kernel crude oil could be reduced by 33.0%-36.4%, 26.7%-29.4%, 15.0%-18.7% and 22.5%-23.0%, respectively. All in all, the quality of peanut raw material from different origins was quite different, the PAEs content in crude oil was significantly different under different oil production processes, and the solvent-extracted oil had higher degree of risk of PAEs pollution than the oil obtained by pressing. The oil obtained from peanut after peeling could reduce the PAEs content in crude oil, reducing the exposure risk of PAEs in crude oil. In the production of peanut oil, especially for the roasted fragrant peanut oil production, the contents of PAEs in peanut kernels should be strictly controlled by using peeled peanuts and pressing technique to produce crude oil, which is important for the prevention and control of PAEs in peanut oil products.

    • 摘要: 为了提高水酶法提取亚麻籽油的提油率,该文探究了亚麻籽表面黏质物的存在对水酶法提取亚麻籽油提油率的影响,并对热水浸提法脱除亚麻籽黏质物的工艺进行优化.结果表明,水酶法提取亚麻籽油的提油率随亚麻籽表面黏质物的减少而升高,未脱黏亚麻籽的提油率为69.20%±1.51%,渣相含油量为26.00%±1.24%.经100 °C浸提脱黏后,黏质物的脱除率为94.69%±1.94%,此时亚麻籽的提油率可达84.26%±0.63%,渣相含油量降低至10.45%±0.89%.对热水浸提脱除黏质物的工艺(浸提温度、浸提时间、体系pH值、料水比以及浸提次数)进行了单因素优化,发现在浸提温度85 °C、pH值3、料水比1:7 g/mL、浸提2次,每次浸提60 min的条件下,黏质物的脱除效果最好,脱除率为97.88%±0.69%,脱黏后亚麻籽的提油率可达84.47%±0.53%,亚麻籽油和蛋白质的损失率分别为0.70%±0.16%和10.78%±0.41%,且浸提脱黏过程对水酶法提取亚麻籽油的品质(酸值和过氧化值)无显著影响.此外,浸提脱黏过程还可有效去除亚麻籽中的抗营养因子生氰糖苷,使生氰糖苷的含量由浸提前的(242.6±0.8)mg/kg显著降低到浸提后的(7.1±0.6)mg/kg.该研究提供了一种简单高效的热水浸提脱黏工艺,显著提高了后续水酶法提取亚麻籽油的提油率,同时也有利于亚麻籽多糖的回收和亚麻籽粕的进一步利用,为亚麻籽资源的综合利用提供有益参考.%Flaxseed, which is also called linseed, is an kind of important oilseed in the world. The nutritional components of flaxseed are oil, protein, lignans, soluble fiber, minerals, and vitamin, and so onetc. It is known as the richest source of the n-3 fatty acid, alpha linolenic acid (n-3 fatty acid), which comprises approximately 55% of the total fatty acids, and this percentage is 5.5 times higher than that in the second next-highest sources. Flaxseed plays an important role in functional foods for its nutritional and pharmaceutical values. In recent years, aqueous enzymatic extraction, an emerging alternative to hexane-based oilseed extraction regarding product safety and simultaneous recovery of high quality protein products and high yield of vegetable oils has drawn increasing attentions over decades. However, due to the high water-holding capacities, stabilization and emulsification properties of flaxseed mucilage, extraction and separation of flaxseed oil from raw flaxseed by aqueous enzymatic method are proved to be inefficient and even prohibitive. In order to improve the yield of flaxseed oil extracted by aqueous enzymatic method, the effect of demucilage on the aqueous enzymatic extraction of flaxseed oil was investigated by comparing the yield of flaxseed oil before and after removal of flaxseed mucilage through hot water extraction. Results showed that the mucilage on the surface of flaxseed significantly impeded the separation of oil from aqueous enzymatic extraction system, thus resulting in a low extraction yield of flaxseed oil. More specifically, the oil yield of raw flaxseed was only 69.20%±1.51% and residual oil content in insoluble phase was 26.00%±1.24%, while after removal of 94.69%±1.94% mucilage by hot water extraction treatment at 100 °C (the removal rate of 94.69%±1.94%), the yield of flaxseed oil significantly increased to 84.26%±0.63% and residual oil content in insoluble phase decreased to 10.45%±0.89%. Mucilage removal conditions were optimized by single- factor experiments and the optimal conditions were obtained as follows:eExtraction temperature was 85 °C, pH value was 3, flaxseed- to- water ratio was 1:7 g/mL, extraction time was 60 min and extraction was repeated twice. Under the optimum conditions, the mucilage removal efficiency was 97.88%±0.69%, the yield of the flaxseed oil reached to 84.47%±0.53%, and the loss ratios of flaxseed oil and protein were 0.70%±0.16% and 10.78%±0.41%, respectively. Acid value and peroxide value of the flaxseed oil before and after demucilage by hot water extraction treatment were determined and it was found that the demucilage process had no obvious influence on the quality of flaxseed oil extracted by aqueous enzymatic method. In addition, after the hot water extraction process, the content of cyanogenic glycosides in flaxseed was significantly decreased from 242.6±0.8 mg/kg to 7.1±0.6 mg/kg. The proposed flaxseed demucilage -method was simple and efficient, which not only significantly improved the yield of flaxseed oil with aqueous enzymatic method, but also laid a good foundation for preparation of flaxseed gum from the extract and further utilization of the flaxseed meal. Therefore, it presentsed a promising technology for the comprehensive utilization of flaxseed on industrial scale.

    • 摘要: 随着人们生活水平的不断提高,消费者对食材的选择也愈加重视。如今市面上,压榨油越来越得到人们的青睐,许多商家也以其"绿色、健康"为卖点进行宣传。有些人认为压榨油纯天然更健康,而浸出油由于制作中需要化学溶剂萃取,便被冠以"不健康"的头衔,事实果真如此?压榨油和浸出油的制作工艺不同压榨法是通过物理方法,借助外力挤压油料,从中提取油脂的传统生产方法。据史料记载,人类用此方法获得油脂已有5000多年历史。

    • 摘要: 采用浸出法,以正己烷(n-hexane)、丙酮(acetone)、石油醚(petroleum ether)为提取剂提取核桃油,结果在料液比为1:8时石油醚提油率最高.核桃油的过氧化值可以代表核桃油的品质;核桃油的过氧化值越高,品质越低.在不同的时间、温度和抗氧化剂种类不同的条件下,利用核桃油的过氧化值探索核桃油品质的过程中发现,抗氧化能力PG>BHT>生育酚,并随着对核桃油处理时间的延长和温度的升高,抗氧剂的抗氧化作用减弱,所以在储存核桃油时要注意温度不能过高.

    • 摘要: 我国黄金储量较为丰富,但还存在着一些难处理的金矿,在我国金矿资源中占有较大的比例,这类金矿如果采用直接氰化浸出,则浸出率较低,所以常规的氰化法有效浸出金矿石具有不适用性,对于难浸金矿石需要选择适宜的处理方法.本文对难浸金矿石预处理后浸出法和强化氰化浸出法进行了具体的分析,并进一步对非氰化法进行了简单的介绍.

    • 摘要: 不刷锅就炒菜、炒完菜就关油烟机……这些看起来居家省钱的良方,其实却在毒害我们的健康。炒菜后不刷锅接着炒:产生苯并芘致癌很多人都有这样的习惯,刚炒过鸡蛋,锅里还有一些底油,放点油再接着炒其他的菜,这样既省事也省油。但营养师表示,看似干净的锅表面会附着油脂和食物残渣,当再次高温加热时,可能产生苯并芘等致癌物。而且不刷锅接着炒菜,原本在锅里残余的菜很容易烧焦,这也存在一定的致癌隐患。
