旨在为风味香榧籽油的开发提供理论支持，考察了不同加工工艺（烘烤温度和压榨工艺）对香榧籽油理化指标的影响，并采用电子鼻、顶空固相微萃取-气质联用（HS-SPME-GC-MS/MS）等技术研究不同烘烤温度（140、150、160、170、180 ℃）和压榨工艺（螺杆压榨和液压压榨）对香榧籽油中挥发性物质组成的影响。结果表明：烘烤温度和压榨工艺对香榧籽油酸值影响较小，随烘烤温度的升高，螺杆压榨和液压压榨对香榧籽油过氧化值的影响不同，但不同烘烤温度和压榨工艺条件下制取的香榧籽油酸值和过氧化值均符合GB 2716—2018中的要求；电子鼻分析表明氮氧化合物、硫化物、芳香成分、甲基类物质对香榧籽油风味的影响较大；液压压榨和螺杆压榨香榧籽油风味最浓郁的烘烤温度分别为140 ℃和170 ℃；香榧籽油中共检出挥发性物质7类42种，其中萜烯类物质占主导；不同温度烘烤后液压压榨制取的香榧籽油中共有5种挥发性物质的相对含量发生显著变化，而螺杆压榨制取的香榧籽油中有18种挥发性物质的相对含量发生显著变化，柏木脑和香芹酮为两种压榨工艺共有的相对含量发生显著变化的物质。综上，压榨工艺会影响香榧籽油达到浓郁风味所需要的热风烘烤条件，且螺杆压榨相较于液压压榨，其风味物质种类变化更加丰富。Aiming to provide theoretical support for the development of flavour Torreya seed oil, the effects of different processing techniques (roasting temperature and pressing process) on the physicochemical indexes of Torreya seed oil were investigated, and the effects of different roasting temperatures (140, 150, 160, 170, 180 ℃) and pressing processes (screw press and hydraulic press) on the composition of volatile substances in Torreya seed oil were studied by using the techniques of electronic nose and headspace solid-phase microextraction coupled with gas chromatography and mass spectrometry (HS-SPME-GC-MS/MS).The results showed that the roasting temperature and pressing process had less influence on the acid value of Torreya seed oil; with the increase of roasting temperature, screw pressing and hydraulic pressing had different influences on the peroxide value of Torreya seed oil; however, the acid value and peroxide value of the Torreya seed oil produced under different conditions of roasting temperature and pressing process complied with the requirements of GB 2716-2018; the electronic nose analysis reflected the greater influence of nitrogen oxides, sulfides, aromatic components, and methyl groups on the flavour; the roasting temperatures for achieving the most intense flavour in the two pressing methods, hydraulic press and screw press, were 140 ℃ and 170 ℃, respectively; a total of 42 volatile substances were detected in Torreya seed oil in 7 categories, of which terpenes were dominant; the content of 5 volatile substances changed significantly in hydraulically pressed Torreya seed oil and 18 in screw pressed Torreya seed oil after roasting at different temperatures, and cedrol and carvone were common in the two pressing processes. In conclusion, the pressing process affects the hot air roasting conditions required to achieve a strong flavour in Torreya seed oil, and the screw pressing results in a richer variety of flavour substances compared with hydraulic pressing.

为了解决风味（原香和烤香）油茶籽油掺伪浸出油茶籽油的定性判别问题，设计高、低两个掺伪梯度，基于挥发性成分构建并对比分析了定性判别风味油茶籽油掺伪浸出油茶籽油的主成分分析（PCA）模型和逻辑回归模型。结果表明：逻辑回归模型定性判别风味油茶籽油掺伪浸出油茶籽油的能力较强，优于PCA模型；高掺伪梯度下定性判别原香和烤香油茶籽油掺伪浸出油茶籽油，PCA模型的最低检出限分别为20%和60%，而逻辑回归模型的最低检出限均为10%；低掺伪梯度下定性判别原香和烤香油茶籽油掺伪浸出油茶籽油，PCA模型的判别不准确，而逻辑回归模型的最低检出限均为4%。逻辑回归模型能很好地定性判别风味油茶籽油掺伪浸出油茶籽油。 Based on volatile components, principal component analysis (PCA) and logistic regression (LR)models were constructed and compared to solve the problem of qualitative identification of flavor (original/roasted) oil-tea camellia seed oil adulterated with leaching oil-tea camellia seed oil under high and low adulteration gradients.The results showed that LR model had a good ability to qualitatively identify the flavor oil-tea camellia seed oil adulterated with leaching oil-tea camellia seed oil, which was better than that of PCA model. Under the high adulteration gradient, the detection limit of the PCA model for original/roasted oil-tea camellia seed oil adulterated with leaching oil-tea camellia seed oil was 20%/60%, and the detection limit of the LS model was 10%/10%, respectively. Under the low adulteration gradient, the detection limit of LR model for original/roasted oil-tea camellia seed oil adulterated with leaching oil-tea camellia seed oil was 4%/4%, but the discriminative ability of the PCA model was not accurate.The LR model can qualitatively identify flavor oil-tea camellia seed oil adulterated with leaching oil-tea camellia seed oil.

为了研究油茶籽油氧化稳定性机制，了解不同预处理方式对油茶籽油抗氧化能力的影响，以DPPH自由基清除能力为指标，对油茶籽分别经红外与微波预处理后得到的油茶籽原油及其极性组分和非极性组分抗氧化能力进行分析。结果表明：油茶籽分别经红外和微波预处理后，得到的油茶籽原油及其极性、非极性组分DPPH自由基清除能力变化显著；红外预处理的油茶籽所制油茶籽原油及其非极性组分的DPPH自由基清除能力高于相应微波预处理，其最大值分别高3.53 μg/g和6.47 μg/g；微波预处理的油茶籽所制油茶籽原油中极性组分的DPPH自由基清除能力最大值比相应红外预处理的高38.77 μg/g。油茶籽原油对DPPH自由基的清除能力主要来自其极性组分，非极性组分的DPPH自由基清除能力弱于极性组分。 In order to study the oxidation stability mechanism of oil-tea camellia seed oil and understand the effect of different pretreatment on the antioxidant capacity of oil-tea camellia seed oil, the antioxidant capacity of crude oil-tea camellia seed oil and its polar and non-polar components obtained from oil-tea camellia seed pretreated by infrared and microwave were analyzed using the DPPH radical scavenging capacity as the index. The results showed that the DPPH radical scavenging capacity of crude oil-tea camellia seed oil and its polar and non-polar components changed significantly after infrared and microwave pretreatment of oil-tea camellia seed respectively. The DPPH radical scavenging capacity of crude oil-tea camellia seed oil and its non-polar components from the oil-tea camellia seed pretreated by infrared was higher than that of the corresponding microwave pretreatment, and its maximum values were 3.53 μg/g and 6.47 μg/g higher respectively. The highest DPPH radical scavenging capacity of polar component of crude oil-tea camellia seed oil made from microwave pretreated oil-tea camellia seed was 38.77 μg/g higher than that of corresponding infrared pretreated. The DPPH radical scavenging capacity of crude oil-tea camellia seed oil was mainly from its polar components, while the scavenging effect of non-polar components was weaker than that of polar components.

为解决油茶籽油掺伪其他植物油的定性鉴别问题，在油茶籽油中分别掺入大豆油、花生油、葵花籽油、棉籽油、葡萄籽油、菜籽油、棕榈油和米糠油，设置高和低两种不同掺伪梯度，基于14个特征性脂肪酸和甘油三酯指标，运用Python语言构建并对比分析了二分类决策树模型、多分类决策树模型和多层感知机人工神经网络(MLP-ANN)模型用于油茶籽油掺伪定性鉴别的效果。结果表明：高和低掺伪梯度下，二分类决策树模型对油茶籽油掺伪其他植物油的定性鉴别的准确率均达到0.95以上；多分类决策树模型的精确率和准确率在高掺伪梯度下均达到了0.95，但在低掺伪梯度下仅为0.90；在高和低掺伪梯度下，MLP-ANN模型对油茶籽油掺伪定性鉴别的平均精确率均达到0.98，准确率分别达到0.97和0.98。相比于决策树模型，MLP-ANN模型能很好地实现油茶籽油掺伪定性鉴别。 In order to solve the qualitative identification problem of adulterated oil-tea camellia seed oil with other vegetable oils, soybean oil, peanut oil, sunflower seed oil, cottonseed oil, grape seed oil, rapeseed oil, palm oil and rice bran oil were mixed into oil-tea camellia seed oil respectively, two different adulteration gradients of high and low were set up, and based on characteristic fatty acid and triglyceride indicators, the effects of the binary decision tree model, multi-classification decision tree model and multilayer perceptron artificial neural network (MLP-ANN) model for qualitative identification of adulterated oil-tea camellia seed oil were compared and analysed using Python language. The results showed that the accuracy of the binary decision tree model for qualitative identification of oil-tea camellia seed oil adulterated with other vegetable oils under high and low adulteration gradients was above 0.95. The accuracy and precision of the multi-classification decision tree model reached 0.95 at high adulteration gradient, but only 0.90 at low adulteration gradient. Under high and low adulteration gradients, the average precision of MLP-ANN model for qualitative identification of adulterated oil-tea camellia seed oil reached 0.98, and the accuracy reached 0.97 and 0.98 respectively. Compared with the decision tree model, the MLP-ANN model can well realize the qualitative identification of adulterated oil-tea camellia seed oil.

[Objective/Meaning]In the process of realizing the rural revitalization, the research on the factors that affected the transformation of migrant workers’ willingness to return home to start businesses into entrepreneurial behaviors and its mechanism of action could better help the migrant workers to start businesses, promote their income growth, and narrow the gap between the urban and rural areas. [Methods/Procedures]The method of literature research was used to sort out the relevant research on migrant workers’ returning home to start businesses from 2010 to 2022, and the influencing factors for the transformation of migrant workers’ willingness to return home to start businesses into entrepreneurial behaviors were explored from the factors that affected the migrant workers’ willingness to return home to start businesses and their entrepreneurial behaviors.[Results/Conclusions]The research showed that the research themes of the domestic scholars on the willingness and behavior of migrant workers returning home to start businesses were roughly similar, which could be summarized as the current situation, influencing factors of migrant workers to return home to start businesses and its mechanism of action. However, there were some differences in the content, method and research depth. Based on this, the countermeasures were put forward including paying special attention to the reasons for the deviation of migrant workers’ willingness and behaviors to return home to start businesses caused by the family economic supporting policies and evaluating the practical role of these supporting policies in promoting the migrant workers to return home to start businesses.

Puerarin thermal-sensitive molecularly imprinted polymers (MIP2) were synthesized by precipitation polymerization which containing puerarin as templates, acrylamide (AM) as functional monomers, N-isopropylacrylamide (NIPAM) as temperature sensitive monomer and ethylene glycol dimethacrylate (EGDMA) as crosslinkers. Static adsorption demonstrated that these imprinted polymers possessed well specific adsorption properties for puerarin, the adsorbing capacity reached 45.51 mg/g when concentration of quercetin was 1 mg/mL for MIP2, and the adsorption process accorded with Langmuir model. The MIP2 exhibits temperature responsive behavior, which had a higher adsorption capacity at low temperature (30 ℃). This study can provide some new thoughts and methods to separate and purify puerarin from natural medicines. [ABSTRACT FROM AUTHOR]
