Description

{Method for increasing the content of physiologically active ingredients and nutrients in Sparassis crispa}

The present invention relates to a method of increasing the content of physiologically active ingredients and nutrients of flower mushrooms ( Sparassis crispa ).

Mushrooms have a unique taste and aroma and contain a large amount of nutritionally important nutrients such as essential amino acids, proteins, and minerals. Furthermore, it contains antioxidant substances that protect the body from oxidative stress by pharmacologically inhibiting the oxidation reaction of oxygen radicals and the reactivity of radicals that cause aging, cancer, etc., as well as the function of immune activators and antibacterial, antiviral, and antitumor effects. It is reported to contain a large amount of beta-glucan (Cho et al., 2014; Choi et al., 2010; Barros et al., 2007; Han et al., 2015; Manzi et al., 2001; Qi et al., 2013). As interest in improving quality of life has steadily increased along with recent improvements in living standards and income levels, the use and interest in various bioactive components of mushrooms is gradually increasing (Park et al., 1995; Song et al., 1995). al., 2003).

The domestic mushroom industry has reached a saturation point as production volume has increased compared to supply and demand, prices have fallen due to export slowdown, and the domestic market has been met to a significant level. As a result, farm profitability is gradually deteriorating (Chang, 2008; Lee and Seo, 2005). Furthermore, more than 90% of the mushrooms consumed in Korea are large oysters, oysters, enokis, button mushrooms, and shiitake mushrooms, which is worsening the product concentration phenomenon (Lee et al., 2017). Yeom et al. analyzed the current status and improvement tasks of the mushroom industry. (2019), as a result of the Hierarchical Analysis Method (AHP), the priorities for each sector of the mushroom industry were analyzed to be 1st in the export and marketing sector and 2nd in the processing sector, and development of functional mushroom varieties through consumer preference surveys, etc. The need to develop and produce various varieties and develop new products that fit domestic and international consumer characteristics and trends was emphasized. In addition, Lee and Seo, (2005) stated that the development direction of the mushroom industry should be to form a domestic market to meet demand, develop and export high value-added products, and develop not only mushrooms but also forward and backward industries centered on mushrooms. . In order to overcome this vicious cycle of recession in the domestic mushroom industry, the development of various processed products as well as the development of mushroom varieties that meet the consumption needs of consumers in addition to the fresh mushroom market is urgently needed.

As the various beneficial effects of mushrooms become known, they can be said to be highly utilized as health functional foods. However, since most mushroom consumption appears to be limited to homes and restaurants, it is believed that raw mushrooms are still mainly used in cooking (Jo et al., 2009). In addition, functional mushrooms such as hangover relief drinks, bread, noodles, and biscuits have been used as food ingredients and general foods, and several patents and processed products have been developed (Park, 2008). If you use the dried mushroom powder produced in the first processing during the development of processed mushroom products and mix it with coffee, tea, seasoning, solid broth additives, etc., you can also consume the functional ingredients of the mushroom.

Meanwhile, cauliflower mushroom ( Sparassis crispa ) is a mushroom that belongs to the noodle mushroom family and has a good chewy taste and a subtle scent like pine mushrooms. It is known as an adaptogen with anti-cancer effects like reishi, shiitake mushrooms, and Cordyceps sinensis. In other words, this cauliflower mushroom has no side effects, its medicinal effects are not limited to specific organs or organs, and it is a mushroom with a normalizing effect, and has been used in the field of oriental medicine for a long time.

The medicinal ingredients and efficacy of cauliflower mushrooms have been systematically studied in Japan and the United States. As a result, it was found that the anticancer activity of cauliflower mushrooms comes from complex polysaccharides, and is particularly effective in enhancing anticancer and immune function. It is known to contain more than 10 times the beta-glucan content of medicinal mushrooms such as Reishi or Sanghwang mushrooms.

The chemical structure of β-glucan, the main complex polysaccharide of cauliflower mushrooms, is different from the structure of β-glucan found in other medicinal mushrooms. It is in the form of branch-shaped β-1,3-glucan, which is the most powerful stimulating cellular immune response. It is an ingredient. In addition to its anti-cancer properties, cauliflower mushrooms are known to have antibacterial, diuretic, and tonic properties due to the β-1,3-glucan contained in them, and mannitol and trihalogen are known to have anti-cancer, anemia, and sedative properties. Research on AIDS and anti-HIV effects is also underway. Like other medicinal mushrooms, cauliflower mushrooms also work to regulate blood pressure, blood sugar, and blood cholesterol.

Therefore, the present invention relates to a method of increasing the content of physiologically active ingredients and nutrients of flower mushrooms, and is involved in the antioxidant and immune properties of flower mushrooms through setting the optimal roasting temperature according to the present invention. It can be expected that the production of raw materials for mushroom processing will be promoted by improving the content of bioactive ingredients and nutrients.

<Example 1> Roasting method to increase the physiologically active ingredients and nutrients of cauliflower mushrooms

The present invention includes the steps of a) chopping 1,400 g of a raw sample of cauliflower mushroom into 7 mm pieces for 1 minute and 30 seconds at a blade rotation speed of 1,200 rpm/min; b) Using a convection hot air dryer using hot water, maintaining the primary temperature conditions in the dryer at 45°C, hot water temperature at 55°C, and mushroom drying time for 30 hours; c) Drying in the dryer as secondary temperature conditions: 60°C, hot water temperature 70°C, drying time 12 hours; d) measuring the moisture content and drying to a moisture content of 7%; e) The roasting device prepared samples by inserting dried mushrooms at a preheated temperature of 75°C and rotating the drum, f) first roasting at 100°C for 4 to 6 minutes; g) secondary roasting at 130°C for 4 to 6 minutes; h) three rounds of roasting at 170°C for 4 to 6 minutes; i) The roasting conditions for the fourth round of roasting at 200°C for 4 to 6 minutes were tested. Samples were obtained at each roasting temperature of 100°C, 130°C, 170°C, and 200°C to confirm the degree of increase in the bioactive and nutritional components of the cauliflower extract.

At this time, if the roasting temperature was lower than 100℃, the roasting effect could not be confirmed at all. If the roasting time was increased, it took longer than necessary and was not suitable for mass production. If the roasting temperature exceeded 200℃, the color of the mushrooms changed. It was confirmed that it turned black, and it had a strong burnt taste, so it was confirmed that it could not be used as a product.

In addition, since the size and thickness vary depending on the type of mushroom, the size of the pieces cut during the pre-treatment process before drying is different, and it was confirmed through experiments that the efficiency of hot air drying and roasting varies depending on the moisture content at the drying stage. It was possible to do this, and through several experiments, the pretreatment conditions including the roasting method of cauliflower mushrooms proposed in the present invention increased the optimal roasting efficiency. According to this method, there is an excellent effect of increasing bioactive ingredients and nutrients.

<Example 2> Confirmation of DPPH radical scavenging ability of cauliflower mushrooms at different roasting temperatures

As a control group, cauliflower mushrooms that underwent only the hot air drying step without going through the roasting step were used, and the roasting temperature was 100°C, 130°C, 170°C, or 200°C.

As shown in Figure 1, the DPPH radical scavenging ability of cauliflower mushrooms at a roasting temperature of 200°C was 25.7%, which was higher than that of samples at other roasting temperatures. When compared to the hot air dried control sample, the roasting temperatures were 100°C, 130°C, and 170°C. The DPPH radical scavenging activity of the ℃ sample was found to be low.

<Example 3> Confirmation of total polyphenol content of cauliflower mushrooms by roasting temperature

The total polyphenol content of the roasted cauliflower mushrooms was confirmed at each roasting temperature through the same steps as in Example 1. As a control group, cauliflower mushrooms that underwent only the hot air drying step without going through the roasting step were used, and the roasting temperature was 100°C, 130°C, 170°C, or 200°C.

As shown in Figure 2, the total polyphenol content of cauliflower mushrooms at a roasting temperature of 200°C was 14.92 mg GAE/g, which was confirmed to be higher than that of samples at other roasting temperatures and hot air dried samples. When compared with the control hot air dried sample, it was confirmed that the total polyphenol content of the sample increased at each roasting temperature, especially at a roasting temperature of 200°C.

<Example 4> Confirmation of beta-glucan content by roasting temperature of cauliflower mushrooms

The beta-glucan content of the roasted cauliflower mushrooms was confirmed at each roasting temperature through the same steps as in Example 1. As a control group, cauliflower mushrooms that underwent only the hot air drying step without going through the roasting step were used, and the roasting temperature was 100°C, 130°C, 170°C, or 200°C.

As shown in Figure 3, the beta-glucan content was found to be higher in all samples except for the sample with a roasting temperature of 100°C compared to the hot air dried sample of cauliflower mushrooms. Additionally, when comparing flower mushroom roasting temperatures, it was confirmed that the beta-glucan content was highest at 19.1% at a roasting temperature of 200°C.

<Example 5> Confirmation of nitrite scavenging ability of cauliflower mushrooms by roasting temperature

The nitrite scavenging ability of the roasted cauliflower mushrooms was confirmed at each roasting temperature through the same steps as in Example 1. As a control group, cauliflower mushrooms that underwent only the hot air drying step without going through the roasting step were used, and the roasting temperature was 100°C, 130°C, 170°C, or 200°C.

As shown in Figure 4, the nitrite scavenging activity of samples roasted at roasting temperatures of 100°C and 200°C was found to be higher than that of hot air dried samples of cauliflower mushrooms. Additionally, when comparing cauliflower mushroom roasting temperatures, it was confirmed that the nitrite scavenging activity was highest at 29.2% at a roasting temperature of 200°C.

Therefore, as described above, when the step of roasting flower mushrooms at 200°C was included, it was confirmed that the DPPH radical scavenging ability and total polyphenol content among the bioactive components related to antioxidants were increased, and the beta-glucan content related to immunity was confirmed to be increased. The invention was completed by confirming that the content was highest at a roasting temperature of 200°C, and that the nitrite scavenging activity, which causes carcinogenesis, was also highest at a roasting temperature of 200°C.
