Abstract

Objective and methodology: the aim of this research was to determine the TAC of foods traditionally prepared in Mexico. TAC was assessed using the oxygen radical absorbance capacity (ORAC) assay, the 2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) radical (ABTS), and 1,1-diphenyl-2-picrylhydrazyl (DPPH) assays. Additionally, the capacity of the samples to reduce ferric ions to ferrous ions (FRAP) was measured.

Results: the TAC of prepared foods and beverages ranged from 6 to 102 µmol ET/g in the ORAC assay, with mole pastes showing the highest values. Beverages ranged from 0 to 25 µmol ET/g in ORAC. For the ABTS assay, values ranged from 21-342 mg EAA/g, from 0 to 297 µmol ET/g with DPPH, and from 11-298 mg EAA/g in FRAP. Foods such as grilled tuna, bell peppers with onions, red mole, stewed huitlacoche, refried black beans, rajas with cream, and corn exhibited the highest values.

Conclusions: the foods and beverages examined in this study exhibited significant TAC, which can be attributed to both: the ingredients (e.g., peppers, tomatoes, spices such as garlic, pepper, cilantro, and lemon) and methods of preparation.

[传统墨西哥食物的自由基清除能力]。

目的和方法：本研究的目的是确定在墨西哥传统制备的食物的TAC。TAC采用氧自由基吸收能力（ORAC）测定法、2,2'-氮基-双（3-乙基苯并噻唑-6-磺酸）自由基（ABTS）测定法和1,1-二苯基-2-吡啶肼（DPPH）测定法评估。此外，还测量了样品将铁离子还原为亚铁离子（FRAP）的能力。结果：在ORAC试验中，预制食品和饮料的TAC在6 ~ 102µmol ET/g之间，以鼹鼠膏最高。饮料中的ORAC含量为0至25µmol ET/g。对于ABTS试验，其值范围为21-342 mg EAA/g， DPPH为0 - 297µmol ET/g， FRAP为11-298 mg EAA/g。烤金枪鱼、洋葱甜椒、红鼹鼠、炖辣酱、油炸黑豆、奶油拉加和玉米等食物的营养价值最高。结论：本研究中检测的食品和饮料显示出显著的TAC，这可归因于两方面：成分（如辣椒、西红柿、香料如大蒜、辣椒、香菜和柠檬）和制备方法。

期刊介绍： The journal Nutrición Hospitalaria was born following the SENPE Bulletin (1981-1983) and the SENPE journal (1984-1985). It is the official organ of expression of the Spanish Society of Clinical Nutrition and Metabolism. Throughout its 36 years of existence has been adapting to the rhythms and demands set by the scientific community and the trends of the editorial processes, being its most recent milestone the achievement of Impact Factor (JCR) in 2009. Its content covers the fields of the sciences of nutrition, with special emphasis on nutritional support.
