In addition to being able to be expected to be imparted, it is possible to obtain a blended tea with an unpleasant odor and a reduced bitterness and an improved aroma and sweetness.
  • a barley that has been subjected to high-temperature and high-pressure steam treatment may be referred to as a “(barley) processed product” for convenience.
  • High-temperature and high-pressure steam treatment was carried out using various pearl barley.
  • the following two kinds of processing barley were used: 1) Roh, barley (non-roasted product, Mitsui & Co., Ltd., control 1); 2) Roasted barley (ITOCHU Corporation, roasting degree: L35, control) Product 2).
  • the pulverized product was obtained using a cutter mill (SKL-A250, manufactured by TIGER) under the condition of pulverizing 30 g for 5 seconds.
  • High-temperature and high-pressure saturated steam (2.7 MPa, 230 ° C) generated using water (oxygen concentration 0.3 g / ml) deoxygenated by a deoxygenator (Miura Kogyo Co., Ltd .: DOR-1000P) is pumped in for about 1 second. As a result, the air in the container was replaced. Then, as shown in Table 1, each temperature of 150 ° C, 0.35 Mpa to 210 ° C, 1.8 MPa. Under pressure conditions, the treatment time is 1 minute to 5 minutes, and saturated water vapor is continuously aerated. High-temperature and high-pressure steam treatment was performed by the above-described method. In each case, after deaeration, the reaction vessel was evacuated and held for 15 minutes, followed by vacuum drying to obtain various pearl barley products listed in Table 1.
  • fragrance was implemented about the obtained various pearl barley products and the control goods. Grain odor, fragrant fragrance, and burnt odor were evaluated as evaluation items. According to the 6 panelists, the average was evaluated based on five levels: not felt (1 point), weakly felt (2 points), felt (3 points), strongly felt (4 points), very strong (5 points) Depending on the point, we have the following notation:
  • the treatment with a high-temperature and high-pressure fluid can impart a fragrance that could not be obtained by roasting, regardless of whether the raw barley is roasted or not crushed. won.
  • Beverages were prepared using the various processed products obtained in Example 1. Of the various processed products, those with a whole shape were pulverized in 30 g for 5 seconds using a cutter mill (SKL-A250, manufactured by TIGER). The pulverized product was used as it was. 2 g of each pulverized product was taken and extracted with 120 ml of hot water for 5 minutes to obtain a beverage.
  • Example 3 Using whole roasted pearl barley, the effects of temperature conditions and processing time on flavor were examined in detail. Under the conditions listed in Table 3, various processed products were produced in accordance with Example 1. For processed products, the scent was prepared by the method in accordance with Example 1. For beverages using processed products, Example 2 was prepared. The scent and taste were evaluated by the method according to the above. The results are shown in Table 3.
  • Each saccharide force which was not found in the control product or was found to be very low even if found, was newly produced in the processed product treated with the high-temperature and high-pressure fluid.
  • monosaccharides such as xylose (low calorie sweetener) and glucose (sweetener) were observed even at relatively low processing temperatures (150 ° C).

  • Table 6 shows the results of evaluating the content of glucose, which is a typical sweetener, in a plurality of processed products.
  • Glucose which was not observed in the control product or was found to be very low even if found, was found to be contained in the processed product treated with high-temperature and high-pressure steam at about 1.2 to 14.6 (mg / g). Katsuta.
  • Liquid feeding conditions Liquid A H20— 1 00%
  • the various processed pearl barley products obtained in Example 3 were measured for free amino nitrogen content (FAN). Using a cutter mill (SKL-A250, manufactured by TIGER), 30 g of the sample was pulverized for 5 seconds. 5 g of each pulverized product was taken in a Mayer, left in a 90 ° C water bath for 15 minutes after adding boiling water, cooled with running water, centrifuged (3500 rpm 10 min), and filtered through a filter paper.
  • FAN free amino nitrogen content
  • a phosphate buffer solution and a TNBS solution were added and held at a predetermined concentration for a predetermined time. Then, a reaction stop solution was added, and the absorbance was measured (spectrophotometer wavelength: 340 nm). By comparing this absorbance with a calibration curve obtained from a glycine standard aqueous solution having a known concentration, FAN (a-amino nitrogen concentration (ppm)) in the sample was calculated, and the amount per unit weight was obtained. The results are shown in Table 8.
  • FAN in rye and rye decreases with normal roasting operations. This is thought to be due to the progress of reactions involving the disappearance of amino acids, such as the Maillard reaction. However, it was found that amino acids increased by high-temperature and high-pressure steam treatment. In Example 2, the FAN was in the range of 0.16 to 0.49 mg / g in the processed product for which the taste evaluation of the tea beverage was good. FAN is the amount corresponding to the total amount of free ⁇ -amino acids, and reflects the amount of amino acids that give food richness. It was found that treatment with a high-temperature and high-pressure fluid produces oleic acid and amino acid that cannot be obtained by roasting operation, contributing to the richness of beverages.
  • Example 3 The processed product obtained in Example 3 was evaluated for the content of 5-hydroxymethylfurfural (5HMF), which is known as a component of burnt odor.
  • 5HMF 5-hydroxymethylfurfural
  • the content of 5HMF increased in the sample treated for a relatively long time in the high temperature region. This result is replaced (26 before the regulation) ' The tendency was the same as the evaluation of burnt odor in Example 3. Considering both results together, the content of 5HMF is considered to be preferably about 3.0 mg / g or less, which is considered to be an index that considers the upper limit of processing conditions when processing with high-temperature and high-pressure fluid. It was.
