How Much Citric Acid Is In Lemon Juice
Lemon juice is a rich source of citric acid providing 1.44 g of citric acid per ounce. It also depends on the size of a lemon. Commercially, the concentration of citric acid in lemon may vary from about 0.03 to 0.02g per ounce.
Lemon juice contains approximately 0.05 grams/ml citric acid. The citric acid content in dried lemons is as high as 8 percent. Lemon and lime juice are both high sources of citric acid, with 1.44 grams and 1.38 grams per ounce, respectively. Citric acid may be used in place of lemon juice in applications where a complex lemon flavor is not needed, just brightness or acidity. Citric acid can also be used in just about any dish to boost acidity without adding any liquid (from vinegar or lemon juice) or particularly strong flavors, except, well, acidity.
Different acids can be used in making cottage cheese, with some methods calling for vinegar (which also may have a wider range), while others use lemon juice. The quantity and type of acid used is key for creamy, smooth, delicious ricotta.
Using citric acid and fresh lemon juice is possible in a number of similar ways, you could add citric acid to fruits or vegetables to create jams, jellies, salsas, or preserves. Citric, malic, and tartaric acids, among others, are found naturally in fruits and vegetables. Citric acid is a common additive and nutrient found naturally in citrus fruits and their juices.
The pH of citrus fruits juices, such as oranges and lemons, depends on the concentration of citric acid, with higher citric acid concentrations leading to lower pH. Lemons and limes have especially high citric acid concentrations; it may make up to 8% of the dried weight of these fruits (about 47 g/L of the juice ). The citric acid content of commercial lemonade and other fruit-juice products ranges greatly, ranging from 0.03 to 0.22 grams per ounce. Lemon juice and lime, both fresh fruits and from water concentrate, contain more citric acid per liter than prepared grapefruit juice, prepared orange juice, and pressed orange juice.
Overall, fairly accurate results were found, with freshly squeezed lemon juice found to contain significantly more citric acid than juice in bottles. Although, when testing our recipe for creamy cottage cheese using only half as much vinegar, results were still insignificant in comparison with those from lemon juice.
The one outcome that any kind of bias could be determined on is the percentage citric acid of bottled lemon juice, or, more accurately, the percentage as grams per 100ml (since this is the kind of percentage Berri Squeeze gives). This 5.16 grams per 100 mL value for bottled juice represents an error of 3.10%, assuming that the true value is 5 grams per 100 mL.
Berri Squeeze states that their bottle juice is generally 5 percent concentrated. I reached out to Berri Juices after conducting my experiments, and found they standardize their juices citric acid content at 5 grams per 100ml (although Berri says it can range from as low as 4 grams, up to as high as 5.2 grams). The following chart shows an estimated juice quantity for small, medium, and large-sized lemons.
The following tips can be used to get maximum amount of lemon juice. Rolling is essential for squeezing lemons to get the most juice. Use a box cutter or peeler to slice lemon peels into long strips.
If you have lots of lemons on hand you need to juice, try using a tabletop hand-cranked citrus reamer. You can use either citrus reamer or juice press for this task. An electric citrus juicer may be used, particularly if you are juiceing lemons for making lemonade.

For pre-treating, you use a mixture of half lemon juice, half water instead of one teaspoon of citric acid for one quart of water, according to the Colorado State University Extension. That means that if a recipe calls for adding 2 tablespoons of canned lemon juice to every quart jar before you can, you could easily substitute 1/2 teaspoon of citric acid. It gives the same tart taste, while adding Vitamin C. There are about 3 grams of citric acid in a single lemon juiced, so add 4-5 tablespoons of lemon juice to every 1 tablespoon of citric acid that a recipe calls for. Just 1/2 teaspoon of citric acid (dissolved in 2 tablespoons of water) can replace 2 tablespoons of lemon juice or vinegar when making fresh cheeses such as cottage cheese or paneer (a weirdly tasty cheese found in tons of Indian dishes).
Bottled lemon juice provides a solid dose of acid, which, if added at recommended amounts, will make sure that your products are safe to go through a boiling-water-bath canner. The average acidity level for fresh lemons is around 5% (also the labelled acidity level for reconstituted bottled lemon juice; some varieties of California lemons, however, are less strongly acidic). Note that although lemon and lime juices are fairly acidic, unfortunately orange and mandarin juices (with pHs 3.30-4.19) are much less acidic, and thus cannot be substituted as safe alternatives. The total acidic content precipitated out of lemon juice with lead acetate is (within the margin of error) the sum of citric acid and malic acid.

Industrial-scale production of citric acid began first in the 1890s, based on Italys citrus fruit industry, in which juice was treated with hydrated lime (calcium hydroxide) to precipitate citrate, calcium, which was isolated and converted to citric acid using dilute sulfuric acid. In this manufacturing technology, which is still the main industrial pathway for citric acid used today, cultures of mold Aspergillus niger were fed on sucrose- or glucose-containing media to make citric acid. In 1917, American food chemist James Currie discovered that specific strains of Aspergillus niger molds can be effective producers of citric acid, and the pharmaceutical company Pfizer began producing at an industrial scale using this technology two years later, followed by Citrique Belge in 1929. In 1977, Lever Brothers was granted a patent for chemical citric acid syntheses starting with aconitic or isocitrate/alloisocitrate calcium salts under high-pressure conditions; this produces citric acid at nearly quantifiable conversion, under what appears to be a reverse, non-enzymatic, Krebs cycle reaction.

Powdered citric acid is used in making citric pepper relish. Because citric acid is one of the strongest dietary acids, citric acids primary application is as flavorings and preservatives in foods and beverages, particularly soft drinks and candies.
Is lemon juice the same thing as citric acid?
Citric acid and lemon juice differ in that citric acid is a concentrated acid component, whereas citric acid, water, vitamin C, and other molecules can all be found in lemon juice. Lemon juice also provides nutritional value, although citric acid has extremely few calories and no nutrients.
Can I use lemon juice instead of fruit fresh?
Throwing fruits like apples, pears, bananas, and avocados in acidic liquids like lemon or lime juice is one of the simplest ways to keep their color. This works because the juice’s citric acid halts the chemical reaction required for browning at its source.
Does bottled lemon juice contain citric acid?
Citric acid is present in lemon and lime juice in quantities of 1.44 and 1.38 g/oz, respectively. Concentrates of lemon and lime juice each contain 1.10 and 1.06 g/oz. Between 0.03 and 0.22 g/oz, the citric acid level of commercially available lemonade and other juice products varies greatly.
