 หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Influence of Thermal Sterilization on Antioxidant Capacity and Total Phenolics of Spicy Thai Foods) ผู้เขียน: เพลินใจ ตังคณะกุล,  ดร.เกศศิณี ตระกูลทิวากร , นางพยอม อัตกวิบูลย์กุล , Boonma Niyomwi, Ngamjit Lowvitoon สื่อสิ่งพิมพ์:pdf AbstractTwo different styles of spicy Thai food were developed. The fi rst group were sauces for readyto- cook products—‘Mee Kathi’ sauce (MeKa), ‘Phat Mee Paktai’ sauce (PMeP), ‘Phat Khimao’ sauce (PKhi). ‘Kaeng Khua’ sauce (KK), ‘Om Isan’ sauce (OmIs), ‘Chu Chi’ sauce (CC) and ‘Homok’ sauce (HoM). The second group was ready-to-eat foods—‘Khao Soi Nuea’ (KSoi), ‘Mu Phat Phrik Khing’ (PPK) and ‘Khua Kling Mu’ (KKM). These foods and sauces were each packed in a stand-up type aluminum pouch and were heated at 120 ?C for an appropriate time of 15, 25 or 30 min. The antioxidant capacity of the methanol extracts obtained from the sterilized food samples ranged from 5.77 to 42.11 mg vitamin C equivalent per 100 g and the total phenolic content of these foods ranged from 27.73 to 145.93 mg gallic acid equivalent per 100 g. Five selected foods, MeKa, KSoi, PKhi, PPK and KKM, were studied for the infl uence of heat on natural antioxidants to scavenge the 1, 1-diphenyl-2-picrylhydrazyl radical and for changes of the phenolic content. The results showed that the antioxidant capacity in KSoi, KKM, MeKa and PPK was enhanced by amounts of 3–113% and the phenolic content was increased in all products, by amounts of 4–52%. |
หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Antioxidant Activity of Northern and Northeastern Thai Foods Containing Indigenous Vegetables) ผู้เขียน:เพลินใจ ตังคณะกุล, ดร.เกศศิณี ตระกูลทิวากร, นางพยอม อัตกวิบูลย์กุล, Boonma Niyomvit, นางสาวกรุณา วงษ์กระจ่าง สื่อสิ่งพิมพ์:pdf AbstractAntioxidant capacities were demonstrated between 13.25–86.00 mg vitamin C equivalent (VCE) per 100 g in 10 Northern foods and 4.63–176.71 mg VCE per 100 g in 10 Northeastern foods. The food that possessed the greatest antioxidant capacity was Sup ma khuea pro, and can be displayed from high to low as Kaeng phak seing da > Kaeng dok sa lae > Kaeng hed la ngok > Kaeng phak huan > Kaeng kae > Sup phak sa meg > Kaeng ka noon on > Kaeng dok ma rum> Kaeng pum > Kaeng naw mai bai ya nang> Lap tao > Sa yod ma kham > Kaeng sai bua > Kaeng phak seil > Kaeng om gai > Kaeng phak wan ban >Kaeng yhuak kluai > Kaeng dok phak plang > Pon pla krua ma noi. Total phenolic content in 100 g of Northern and Northeastern foods ranged from 48.42–225.70 and 15.63–157.62 mg gallic acid equivalent, respectively. Content of protein, fat, total dietary fiber and energy in 100 g were as follows; in Northern foods they ranged from 3.33–13.12, 0.55–3.02, 1.20–4.70 g and 24.67-96.65 Kcal, respectively. In Northeastern foods, protein, fat, total dietary fiber and energy varied from 1.69–5.05, 0.16–1.14, 0.90–3.50 g/100 g and 12.24–64.73 Kcal/100 g, respectively. Nutritionally, all 20 selected foods can be considered as low in fat and energy level. |
