สารต้านอนุมูลอิสระโดยรวมจากดอกไม้ไทยกินได้
Currently in 2020 the world is facing a severe Covid-19 pandemic. More than a 20 million patients were infected and continue spreading the viruses. As a result there has been a huge demand for adequate hand sanitizers in the market especially an alcohol-based spray or gel product. The repeated use of hash formulas containing alcohol having an impact on the skin such as a skin irritant itch dryness an allergic reaction These damaged skin can lead to eczema an inflammatory skin condition. Besides using inappropriate formulation or ingredient in alcohol-based gel products can leave a sticky feeling after using the product. However using a high concentration of alcohol and spray alcohol to avoid this problem is not a suitable solution. Due to alcohol can destroy or inactive viruses takes at least 30 seconds. To reach the level of inactive condition the product should not evaporate too fast. The solve the mentioned problem the semi-gel alcohol-based product was developed by adding the skin moisturizers and Khlu’ s flower extract with high antioxidant activity. According to the result in this research the total phenol content of the flower extract is 3105.44+41.50 GAE mg/L extract whereas the DPPH radical scavenging is 0. 21+ 0. 02 equivalent vitamin C/ ml extract. From the sensory evaluation 20 healthy participated in this research. The majority of participants thought that the developed semi spray-gel product dried quickly and that neither product felt sticky after using. No drying effect on the hands. The product can enhance the moisture on the skin. However the smell needs to be more developed.
ใยอาหารที่มีสารต้านอนุมูลอิสระจากเปลือกถั่วและการประยุกต์ใช้ในผลิตภัณฑ์อาหาร
Foods rich in dietary fiber and antioxidants have attracted great attention to both of consumers and food manufacturers because of their significant health benefits. Increased consumption of dietary fiber improves lowering blood pressure and cholesterol levels. Furthermore it prevent a number of gastrointestinal disorders such as constipation and hemorrhoids. Antioxidants are bioactive compounds that can delay or inhibit the oxidation by inhibiting the initiation or propagation of oxidative chain reactions. These free radical reactions cause human diseases such as cardiovascular disease and cancer. Legumes are an excellent source of compounds having antioxidant. Hence recent research has been focused on the potential utilization of bean coat which was by-products from processing industry to the development of new functional ingredients for food nutrition enrichment. The extraction of bioactive compounds from seed coats are used as a food ingredient for various foods processing such as tofu with soybean hull fiber black bean seed coat in maize flours for the production of cookies and whole wheat bread. Therefore research and development of new functional foods from bean seed coat used as ingredient for the preparation of food products to improve food nutrition will be necessary to provide for Industrial manufacturing according to demand and sufficient for healthy food consumption in the future.
ผลของไคโตซานต่อปริมาณสารต้านอนุมูลอิสระและการต้านทานโรคใบไหม้ในข้าวสังข์หยดพัทลุง
This research was aimed to study the effect of chitosan on total polyphenol contents anthocyanin contents antiradical properties and resistance of rice blast disease in Sung Yod Phatthalung rice (Oryza sativar L.) cultivars. The chitosan was applied on rice leaves at concentrations of 50 100 and 500 ppm compared with the control (without the chitosan and only adding a 0.025% acetic acid respectively). The result showed that 500 ppm of chitosan could significantly increase the total polyphenol contents (220.75 mg GAE/100 g dry weight sample) anthocyanin contents (2.98 mg/100 g dry weight sample) and antiradical properties (83.15%) in the grain extracts of Sung Yod Phatthalung rice. In addition Necrosis test on rice leaves treated with 500 ppm of chitosans clearly indicated the plant resistance againt Pyricularia grisea. Therefore the future studies of chitosan activation mechanism will give more valuable information that possible to be applied in the healthy rice product development and fungal disease control.
Development of germinated brown rice with vegetable juice ready-to-drink beverage
The purposes of this research were to study the ratio of germinated brown rice and plant juice and sweetener types for mixed drink process. The ratio of germinated brown rice and plant juice were varied at 7:3 8:2 and 9:1 in 1 littre of water and sweetener types were changed to sugar sorbitol and honey for adjusted the total soluble solids at 11Brix. Results showed that L* a* and b* values of the mixed drink prepared by germinated brown rice and plant juice at a ratio of 8:2 were 36.17 1.80 and 12.10 respectively. The mixed drink obtained 14.85% DPPH free radical (DPPH 22-diphynyl-1-picrylthydrazyl). Furthermore the fortified honey mixed drink provided highest overall preference score. The score was 7.60 in the 9-point hedonic scale from sensory evaluation.
Effect of the lycopene fortification from gac fruit (momordica cochinchinensis spreng) on quality of chicken nuggets product
The objective of this research was to study the effect of lycopene fortification from gac fruit (Momordica cochinchinensis Spreng) in different levels (1 1.5 2 %) compared with standard formula and addition of BHT 100 ppm on physical properties and consumer acceptance of chicken nuggets product. The analysis showed that the sensorial evaluation of nuggets chicken fortification at 2 % lycopene had accepted overall liking score in range like moderately to like very much (p>0.05) of chicken nuggets. Antioxidant activity using by DPPH and total phenol content were the highest (14.04% and 4.43 mgGAE/g) significantly. Furthermore also found that adding powder lycopene levels had the ability to retard oxidation activities similar BHT 100 ppm after storage at 4 C for a period of one month and inhibit the rancidity effective a 2-fold compared to control.
