The stability of vitamin C in food products such as fruit juices is influenced by a number of factors such as type of fruit maturity state and production factors The environment in which juice is stored can significantly affect its vitamin C content and loss of vitamin C with time Factors that impact the stability of vitamin C at intermediate temperatures in a food matrix Herbig AL Renard C M G C Food Chem 2017 Apr 1 220:444-451 doi: 10 1016/j foodchem 2016 10 012 Post navigation ← Personalised nutritional powder for elderly developed in Optifel European project Influence of mixed gel structuring with different degrees of matrix inhomogeneity on oral residence

Stability of vitamin C (ascorbic acid) in tablets

1 J Pharm Sci 1976 Jul 65(7):963-8 Stability of vitamin C (ascorbic acid) in tablets Rubin SH DeRitter E Johnson JB Stability of ascorbic acid (vitamin C) in various tablet formulations and the nature and extent of formation of decomposition products (dehydroascorbic acid diketogulonic acid and oxalic acid) were determined under normal conditions of storage and in simulated use tests

The thermal stability of vitamin C (including l-ascorbic acid [l-AA] and dehydroascorbic acid [DHAA]) in crushed broccoli was evaluated in the temperature range of 30 to 90 degrees C whereas that of ascorbic acid oxidase (AAO) was evaluated in the temperature range of 20 to 95 degrees C Thermal treatments (for 15 min) of crushed broccoli at 30 to 60 degrees C resulted in conversion of l-AA to

Research on the stability of ascorbic acid (Vitamin C) and other vitamins demonstrates which factors to consider when it comes to the preservation of carbon-based molecules Ascorbic acid is a very important but very unstable organic molecule which is characteristic of the class of organic molecules we know as vitamins (Fig 1)

There are increased losses of vitamin C during large-scale institutional food preparation (see chapter 'Stability in Foods') Vitamin C reserves are also affected by the following factors that influence vitamin C metabolism (Schorah et al 1981): •

Factors that affect vitamin C destruction during processing include heat treatment and leaching The extent of loss depends on the amount of water used and particle size of foods The processing of milk into various dairy products may result in vitamin C losses Ice cream contains no vitamin C

The effect of vitamin C supplementation on coagulability

Von Willebrand factor levels were slightly higher with vitamin C although within the normal range Total cholesterol levels were 10% lower when subjects were receiving vitamin C compared to placebo (167+/-7 mg/dL vs 184+/-7 mg/dL) P=0 007) although the total cholesterol/HDL ratio was

Nov 01 2018Purpose: Vitamin K1 (phytonadione) is a fat-soluble vitamin and an essential cofactor for the synthesis of clotting factors II VII IX X protein C and protein S Vitamin K antagonists deplete vitamin K reserves effectively preventing the synthesis of these clotting factors leading to anticoagulation Overly excessive anticoagulation as evidenced by INRs greater than 5 may

The thermal stability of vitamin C (including l-ascorbic acid [l-AA] and dehydroascorbic acid [DHAA]) in crushed broccoli was evaluated in the temperature range of 30 to 90 degrees C whereas that of ascorbic acid oxidase (AAO) was evaluated in the temperature range of 20 to 95 degrees C Thermal treatments (for 15 min) of crushed broccoli at 30 to 60 degrees C resulted in conversion of l-AA to

Brimmer notes that ascorbic acid is mainly an issue in beverages especially those fortified with vitamin C Solutions include using encapsulated ascorbic acid or natural colorants generally others besides the anthocyanins since ascorbic acid tends to degrade anthocyanins However some increased-stability anthocyanins options exist

Feb 01 2016The differences in vitamin C stability among foods and samples of the same food might be explained by the effect of pH factors affecting enzyme activity heat denaturation of enzymes and/or the presence of heat-resistant enzymes and other matrix components either promoting or protecting against irreversible oxidation (Spnola et al 2013)

Vegetables and fruits are a natural sources of biological antioxidants Vitamin C is an essential micronutrient which plays an important role in human health Its deficiency results in a disease referred to as scurvy in humans The objective of this

Oct 11 2019The culprit: oxidation of the vitamin C Luckily once you understand how this happens there are ways to prevent it Vitamin C is ascorbic acid When reading about vitamin C you might come across the name ascorbic acid Ascorbic acid is vitamin C it's just the chemical name As the name says vitamin C is an acid

Factors influencing the stability of ascorbic acid in total parenteral nutrition infusions Allwood MC Ascorbic acid stability in TPN infusions in 3-litre plastic bags was examined Vitamin C was found to degrade slowly in mixtures which do not contain trace elements In the presence of copper degradation proceeds rapidly until dissolved

They blended Vitamin C-rich vegetables — including peppers green peas spinach pumpkin and carrots — with water and heated the samples monitoring the Vitamin C content The researchers found that it isn't just water and heat but time as well that plays a critical role in the Vitamin C
