Total Polyphenols Direct

Quantitative Determination of total polyphenols in edible oils, wine and food Description The antioxidant capacity of polyphenols plays an important role in the stability of olive oil, as there is a correlation between the amount of total polyphenols and resistance to oxidation. Polyphenols have a protective effect on the cells of the human body because they oppose the negative effects of free radicals. These polyphenols in olive oil act as natural antioxidants. The amount of polyphenols decreases during olive oil extraction, so the test can be used to optimize the processing. Olive oil is rich in polyphenols, which form its "polar fraction" and prevent its self-oxidation, thus giving it its excellent thermal stability and contributing to its characteristic aroma and taste. The main ones are: tyrosol, hydroxytyrosol, oleuropein and protocatechuic, gallic, vanillic, vanillic, p-hydroxybenzoic, syringic, 4-hydroxyphenyl acetate, omavanillic, quinamic, o-coumaric, p-coumaric, caffeic, ferulic and sinoacetic acids. The main antioxidants of olive oil are considered to be tocopherols, the main representative being alpha-tocopherol, and phenolic compounds. Vitamin E with its parent compound tocol consists of two series of compounds: tocopherols and tocotrienols. The tocopherols are divided into a-tocopherol, b-tocopherol, c-tocopherol, and d-tocopherol, while the tocotrienols are divided into a-, b-, c-, and d-tocotrienol. The total biological activity of vitamin E is mainly due to the presence of αtocopherol. It is the alpha-tocopherol that exerts the greatest biological activity in the human body and is the reference for the action of the other forms of vitamin E. All tocopherols are natural antioxidants of oils, since they have an antioxidant activity that increases from a to d. The stability of olive oil to oxidation is largely due to the presence of tocopherols, which are easily oxidised. A-tocopherol is traditionally considered the main antioxidant in olive oil. It constitutes about 90% of all tocopherols and normally ranges from 100 to 300 ppm (Blekas et al., 1995; Psomiadou and Tsimidou, 1998). c-Tocopherol constitutes about 8% of all tocopherols in olive oil, while b-, d-tocopherols are only present in trace amounts (Andrikopoulos et al., 1989). Vitamin E is an important natural antioxidant of oils, since it inhibits the oxidation of their fatty substances (triglycerides), and protects olive oil from peroxidation and the free radical propagation mechanism.

L-Ascorbic Acid Direct (Vitamin C)

QUANTITATIVE DETECTION OF L-ASCORBIC ACID Ascorbic acid is a nutrient the human body needs in small amounts to function, and it can help prevent cell damage caused by free radicals— unstable molecules that can damage cells. It can also help the human body fight bacterial infections. Cosmetics and other personal care products may include less acidic forms of ascorbic acid, which can act as antioxidants to slow product deterioration. The FDA states that ascorbic acid is a generally recognized as safe substance for use as a chemical preservative in foods and as a nutrient or dietary supplement. The Cosmetic Ingredient Review states that ascorbic acid and its salts are safe for use in cosmetic and personal care products. According to the U.S. National Cancer Institute, ascorbic acid can help the human body fight bacterial infections and help form collagen, an important protein in fibrous tissue, teeth, bones, skin and capillaries.

FFA Direct

Quantitative measurement of Acidity in fats & oils Description The acidity level of edible oils and fats is determined by the amount of free fatty acids produced by the breakdown of triglycerides during hydrolytic rancidity. Since this change takes place under unfavourable conditions for the processing and preservation of fats, acidity serves as a fundamental measure of the authenticity of the product. This test is particularly critical in the refining of oils and fats, as it contributes to the evaluation of the processing cycle and the classification of products. Although it has comparable accuracy, this test is simpler to perform than the official AOCS Ca 5a-40 method. In samples with a pH below 7,0, the free fatty acids present react with a colour-producing compound, resulting in a reduction of the colour intensity. The extent of this reduction in colour is directly proportional to the concentration of acid in the sample, expressed as a percentage of oleic acid. Package contents 1 x 0.75 ml R1, 1 x 0.25 ml R2, 5 x 20 ml R3 Number of tests: 100 tests Ref.: 89491 Shelf life: 24 months from date of manufacture Storage & Stability: 2-8°C Sample collection instructions No preparation of olive oil sample preparation is required. For the analysis of samples such as solid fats, butter, margarine, cream, nuts, flours and other extracted fatty foods, it is recommended to follow the guidelines described in the enclosed 'Preparation of test sample for analysis of fatty foods'. This document provides guidance on how to properly prepare these specific samples for analysis and can be obtained from your supplier or from the manufacturer - MenidiMedica Biotech Greece. It will likely include information on techniques such as milling, homogenisation, extraction or other relevant procedures to ensure accurate and representative analysis of the fat content of these foods.
