Embodiment 1

[0104] Embodiment 1 (preparation embodiment): the preparation of test sample and control sample

[0105] Using the method and equipment of the present application, different front-end oil samples were collected, as shown in Table 1 below:

[0106] Table 1: Sample Characterization

[0107] sample name

[0108] Except for the collection method and equipment, other steps involved in this embodiment are conventional steps. Example 2 (Evaluation Example): Flavor Evaluation of Test Samples and Control Samples

Embodiment 2

[0108] Except for the collection method and equipment, other steps involved in this embodiment are conventional steps. Example 2 (Evaluation Example): Flavor Evaluation of Test Samples and Control Samples

[0109] sample

[0110] The test samples 1-3 obtained in Example 1, the control samples 1-3 and a commercially available sesame oil sample purchased were selected.

[0111] evaluation standard

[0112] Randomly select 10 experienced sensory evaluators to describe and score the flavor sensory, and calculate the average score, where the evaluation criteria are scored on a 10-point scale:

[0113] 9 to 10 points: the fragrance is strong, thick and pure;

[0114] 8-9 points: the fragrance is good, pure and full;

[0115] 7-8 points: the fragrance is soft and pure;

[0116] 6-7 points: light fragrance, no peculiar smell,

[0117] 6 points or less: abnormal smell (burnt smell, bitter taste, astringent taste, musty smell, etc.).

[0118] The sensory flavor evaluation res...

Embodiment 3

[0122] Example 3 (Evaluation Example): Flavor Analysis of Test Samples, Control Samples and Commercially Available Samples

[0123] sample

[0124] The test sample 3, the control sample 1 (not segmented) and the commercially available samples with the best flavor evaluation in Example 2 were selected.

[0125] Detection method

[0126] The volatile flavor components of the above three samples were analyzed and summarized by HS-SPME-GC / MS analysis method, and the main flavor compounds of sesame oil were classified, compared and analyzed. The main equipment and parameters of the analysis process are as follows:

[0127] Instrument name: Agilent6890N-5973MSD;

[0128] Chromatographic column: HP-5MS (60m×0.25mm×0.25μm);

[0129] Analysis method: HS-SPME-GC / MS;

[0130] Internal standard: 3-picoline.

[0131] Table 3 shows the component analysis results of the main flavor compounds of the test sample 3, the control sample 1 and the commercially available samples, figure...

Abstract

The invention discloses a sesame oil squeezing method.The sesame oil squeezing method comprises the following steps that a, sesame is put in a squeezer to be squeezed; b, front-section oil is collected, the squeezing length of a squeezing cavity of the squeezer is set as L, and in the advancing direction of the raw material in the squeezing cavity, the front-section oil at least is the oil collected at about the first half of the squeezing length L and at most is the oil collected at about the first nine tenths of the squeezing length L.The method further comprises the step of collection of rear-section oil, wherein relative to the front-section oil, the rear-section oil is the oil collected in the remaining part of the squeezing length L.The invention further discloses sesame oil prepared from the front-section oil and / or the rear-section oil and a derivative product of the sesame oil.The invention further discloses squeezing equipment used for implementing the method.

Description

field of invention [0001] The application relates to the field of edible oil manufacturing and processing, in particular, the application relates to a sesame oil pressing method, equipment and prepared sesame oil. Background of the invention [0002] Sesame oil is a common edible oil. Compared with other vegetable oils, it has unique properties in many aspects such as chemical and biological properties. Most of these unique properties come from its unique unsaponifiable components, such as sesamol, sesamin and sesamolin, etc. These endogenous antioxidants make sesame oil have good resistance to oxidative deterioration. Sesame oil is a natural salad oil that hardly needs winterization, and is one of the few vegetable oils that can be eaten directly without any refining. Sesame oil is also the base ingredient of many aromatic oils. [0003] The traditional oil-making methods of sesame oil include water-based grinding, and manual or livestock-powered wedge pressing, wood pres...
