Antioxidant activity of vitamin C, E, and provitamin A

Grasas y Aceites, 1993
As a continuation of the study of natural antioxidants, this paper includes vitamin C (ascorbic acid), vitamin E (tocopherols and tocotrienols), and provitamin A (β-carotene, lutein, zeaxanthin, isozeaxanthin, lycopene, astaxanthin and cantaxanthin) and, as well as those derivatives of these which have been described as antioxidants, either used as ...

Vitamin A bioefficacy of traditional and provitamin A‐biofortified banana

The FASEB Journal, 2011
The provitamin A biofortification of banana could provide a sustainable and cost effective method to ameliorate vitamin A deficiency in many tropical countries where banana is a staple food. However, matrix effects in banana may limit the absorption of vitamins, which could render biofortification efforts ineffective.

Provitamin A and Vitamin C in Salted Nozawa-na

Eiyo To Shokuryo, 1963
The common scarcity of vegetables, especially of leafy ones in winter season makes it important to investigate the convenient sources of vitamin A and C during this season. The growing of the leafy vegetable Nozawa-na (a variety of Brassica Rapa LINN.) is practiced in the central mountaineous region of Japan in autumn, and then they are salted down for

Scientific Opinion on the safety and efficacy of niacin (nicotinamide) as feed additive for all animal species based on a dossier submitted by Agrinutrition BV

EFSA Journal, 2012
The term ‘niacin’ is used as generic description of nicotinic acid and nicotinamide with pyridine as the basic structure. Nicotinic acid and nicotinamide function mainly as precursors of the co‐enzymes NAD and NADP. Thus, nicotinamide has physiologically

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

Food Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic

Mechanisms involved in the intestinal absorption of dietary vitamin A and provitamin A carotenoids [PDF]

Biochimica et Biophysica Acta (BBA) - Molecular and Cell Biology of Lipids, 2012
Vitamin A is an essential nutrient for humans and is converted to the visual chromophore, 11-cis-retinal, and to the hormone, retinoic acid. Vitamin A in animal-derived foods is found as long chain acyl esters of retinol and these are digested to free fatty acids and retinol before uptake by the intestinal mucosal cell. The retinol is then reesterified

Overlapping Vitamin A Interventions with Provitamin A Carotenoids and Preformed Vitamin A Cause Excessive Liver Retinol Stores in Male Mongolian Gerbils [PDF]

The Journal of Nutrition, 2020
Vitamin A (VA) deficiency is a public health problem in some countries. Fortification, supplementation, and increased provitamin A consumption through biofortification are efficacious, but monitoring is needed due to risk of excessive VA intake when interventions overlap.Two studies in 28-36-d-old male Mongolian gerbils simulated exposure to multiple ...
