Although other voltammetric methods e. The concentrations of ascorbic acid in fruit juice determined by cyclic voltammetry are in good agreement with the data obtained by a classical volumetric method Table 2. The obtained results are also in good agreement with the data reported in literature regarding the content of ascorbic acid in citrus fruits.
She also received personal trainer certification from NASM and her hour yoga teacher certification from YogaWorks. Cut limes on a wooden table. In fact, of all citrus fruits, lemons and limes have the highest citric acid content -- about 1.
Lemons and limes also contain ascorbic acid, or vitamin C, an essential nutrient you need in your diet, and malic acid. Video of the Day Citric Acid Facts Citric acid is a weak organic acid that is found in concentrated amounts in citrus fruits, especially lemons and limes.
Citric acid from lemons and limes is often used as an additive in food preparation, both to add a tart flavor and as a preservative. For example, citric acid helps prevent browning of fresh vegetables and maintains the color of meat during storage.

It also prevents the crystallization of sucrose in candy and promotes flexibility and separation of cheese slices. Potential Benefits of Ascorbic Acid Citric acid is not a necessary part of the human diet, but it may have a role to play in your health.
According to the UW Hospital Metabolic Stone Clinic, it can be beneficial for people who have kidney stones because it inhibits their formation and helps break up stones that are starting to form. A study published in Journal of Biochemistry and Clinical Nutrition in November suggests that citric acid can help reduce physical fatigue.
Study participants were given either a citric acid supplement or placebo and made to perform a strenuous physical task. Physiological stress markers were lower in the citric acid group, as was the subjective feeling of fatigue reported by participants. Rich in Ascorbic Acid Better known as vitamin C, ascorbic acid is the second type of acid found in lemons and limes in rich supply.
The juice of one lemon provides almost 20 milligrams of vitamin C, which is 30 percent of the daily value.
The juice of one lime provides about 13 milligrams, or a little more than 20 percent of DV. Gram-for-gram, lemons and limes are as good a source of vitamin C, but not as good a source as oranges. Health Benefits of Ascorbic Acid Unlike citric acid, vitamin C is an essential nutrient, meaning you need it in order to function properly and survive.
Vitamin C is also an important antioxidant, a nutrient that prevents damage to your body by free radicals. Free radicals are formed by your body during the metabolism of food and when you are exposed to pollutants such as cigarette smoke, and they contribute to the aging process and the development of cancer, heart disease and arthritis.
A Touch of Malic Acid Lemons also contain a small amount of malic acid, which is tart but enhances the sweetness of sucrose in fruit, according to an article published in the Journal of Experimental Botany in March The body also produces malic acid.
According to NYU Langone Medical Center, malic acid may have therapeutic benefits for individuals with fibromyalgia, a condition that causes pain and tenderness throughout the soft tissues of the body.A method was developed for assessing ascorbic acid concentration in commercial fruit juice by cyclic voltammetry.
The anodic oxidation peak for ascorbic acid occurs at about mV on a Pt disc working electrode (versus SCE). The influence of the potential sweep speed on the peak height was studied. Rich in Ascorbic Acid Better known as vitamin C, ascorbic acid is the second type of acid found in lemons and limes in rich supply.
The juice of one lemon provides almost 20 milligrams of vitamin C, which is 30 percent of the daily value. You May Also Find These Documents Helpful.
Analysis of commercial vitamin C tablets Objective To determine the vitamin C content in commercial vitamin C tablets by titration between vitamin C (ascorbic acid) & iodine solution.
Hence, compare this data with the manufacturer's specification.
Principle In this analysis. Jul 30, · Ascorbic acid was used as standard, and the same concentrations, as the test solution in methanol were prepared.
Two milliliters of the prepared concentration was placed into test tubes and mL of 1 mmol/L DPPH solution in methanol was added. Jul 30, · At the concentrations studied, ascorbic acid has a significantly higher inhibition of the DPPH radical compared to the juice concentrates.
The FRAP of the citrus juice concentrates revealed that the tangerine, lemon, and lime juice concentrates had significantly lower FRAP values ( ± , ± , and ± μmol/L Fe(II. Journal of Analytical Methods in Chemistry is a peer-reviewed, Open Access journal that publishes original research articles as well as review articles reporting methods and instrumentation in chemical analysis, and their application to real-world problems.
