Determination of total sugar content in food is important for a variety of reasons. Sugar is a major contributor to the taste and texture of many foods, and it is also an important source of energy for the body. However, consuming too much sugar can lead to a number of negative health consequences, including weight gain, tooth decay, and an increased risk of developing diabetes and other chronic diseases. As a result, it is important to be able to accurately measure the sugar content of food in order to make informed dietary choices.
There are a number of methods that can be used to determine the total sugar content in food. One of the most common methods is called the Lane-Eynon method, which involves the use of a special reagent to measure the amount of sugar present in a sample. This method is relatively quick and easy to perform, and it is widely used in the food industry to measure the sugar content of products such as fruit juices and soft drinks.
Another method for determining the total sugar content in food is called high-performance liquid chromatography (HPLC). This method involves separating the sugars present in a sample based on their size and charge, and then measuring the amount of each sugar present. This method is more accurate than the Lane-Eynon method, but it is also more time-consuming and requires specialized equipment.
A third method for determining the total sugar content in food is called the spectrophotometric method. This method involves measuring the amount of light absorbed by a sample at a specific wavelength, which allows for the determination of the sugar content. This method is relatively quick and easy to perform, but it is not as accurate as the HPLC method.
Regardless of the method used, it is important to accurately measure the total sugar content in food in order to make informed dietary choices. Consuming too much sugar can have negative health consequences, and being able to accurately measure the sugar content of the food we eat can help us make better choices for our health.
Determination and Comparative Study of Sugars and Synthetic Colorants in Commercial Branded Fruit Juice Products
At different days of storage, titratable acid content diminished hastily from initial to 3 days, and then it diminished steadily Figure treatment from initial to 12th days followed by 3. On the other hand, Khirshapat showed increased pulp pH and TSS at all the storage duration. OBJECTIVE REFRACTOMETRIC METHOD To determine the total soluble solids of strawberry jam and honey samples using a refractometric method. Smith, Colorimetric method for determination of sugars and related substances. At 9th day, the highest 6. In conclusion, the Lane and Eynon titration method was identified as the most effective method for analysis of the total sugar in fruit juice-based products.

Enhancing the growth of date palm Phoenix Dactylifera in vitro tissue by adding date syrup to the culture medium. Then, 200 µL of the silylation reagent, BSTFA, was added to each oximated sample. Results and Discussion 3. According to Figure nd and 3 rd preferences were given to brands 1 and 3, respectively. The total reaction produces a colour yellow-orange that may be measured spectrophotometrically at 490 nm. Consumer Survey This research includes analyzing cross-sectional data gathered through a consumer survey. Experimental Materials The two mango varieties, namely, Langra and Khirshapath, were selected as experimental materials.

Hence, small-scale fruit drinks limited only to particular localities cannot compete in this context. However, synthetic colorants found in all the products from brand-2 were not mentioned in label information. As a consequence, the total sugar content in 1 g of date juice is 0. Chromatograph of the oximated and silylated glucose sample was obtained. Standard Sugar Preparation A small amount of date syrup 20 mg was dried 55 °C, 10 mbar, 2 h using a rotational vacuum concentrator Christ Rvc 2-33IR. Study Area and Population The survey was conducted within the country, Sri Lanka, as the survey was targeted on FBBP consumption in the whole country.
