Our expertise in many specialist areas has been recognised by all sectors of the Food Industry.
Carotenoids or tetraterpenoids, as the fat-soluble nutrients, are one of the most essential components of all photosynthetic organisms mainly ascribed to its eminent photoprotective and antioxidant properties. Dietary food sources of these compounds include a variety of fruits and vegetables such as carrots, sweet potatoes, tomatoes and squash. The carotenoids can be divided into various categories including Beta-carotene (β-carotene), A-carotene (α-Carotene), lutein, zeaxanthin and lycopene. Some of the major benefits of a well-rounded diet that includes all kinds of carotenoids include lowering Inflammation, promoting healthy growth and development, eye and vision health, boosting immunity, and protect the skin from damage. Importantly, different carotenoids have various uses and benefits, for example, the β-carotene is characterized with anti-inflammatory and cancer-protective effects and consumes high amounts of lycopene which can experience a reduced risk of developing prostate cancer. With the increasing demand for analysis of carotenoids from foods, fruits and other sources, our laboratory has been equipped with sophisticated instruments and experienced experts who are specialized in qualitative and quantitative analysis of carotenoids. At Alfa Chemistry , our customers can readily obtain an overview of the main carotenoids and a comprehensive report of the total carotenoid content in your products.

Polysaccharides and sweetener are food additives that are always added in drinks, processed foods and pharmaceutical products to provide the sweet taste of table sugar. Excessive intaking of sugars or the calories that derive from its metabolism represents one of the leading causes of obesity and its related health problems such as heart disease and diabetes. People with diabetes, for example, are characterized with an abnormally high concentration of sugar in blood stream which can lead to damaging effects on blood vessels and other vital body organs. However, polysaccharides and sweeteners (natural or artificial) that containing practically no calories have negligible damaging effect on body because their metabolism follows a different pathway than that of sucrose. Based on that fact, substituting sucrose with artificial sweeteners or polysaccharides is effective in fighting obesity and preventing or managing diabetes. Alfa Chemistry provides an in-depth examination of issues which are closely related to sugar, polysaccharides and sweeteners. Besides, our staffs will offer you with a full description of the subjects that are related to the determination of the content or purity of sugars, polysaccharides or sweeteners. To support your product development, a sensory determination of the sweetening power of raw materials can also be provided by our experts.
The most abundant organic compounds in mammals or mammalian diet are peptides, proteins and glycoproteins which are essential for the body repair cells and can synthesize new cells. Amino acids, the basic composition of these compounds, contain a basic amino (-NH2), an acidic carboxyl functional group (-COOH) and a side chain (R group) that is specific to each amino acid. As the main ingredients of peptides or proteins, amino acids can be divided into alpha-, beta-, gamma- or delta- amino acids according to their functional groups' locations. Many important proteinogenic and non-proteinogenic amino acids have biological functions such as the glutamate (standard glutamic acid) and gamma-amino-butyric acids are the main excitatory and inhibitory neurotransmitters.

Enzymes, a catalyst in living organisms with majority of them are proteins, regulate the vast majority of chemical reactions occurred in living cells. Utilizing of enzymic catalytic reaction is valuable in the food industrial such as fermenting of wine, leavening of bread, curdling of cheese, and brewing of beer. Proteins, the structural elements of a cell, are of great nutritional value and are essential to the continuing functioning of life. Proteins in the foods are known as macronutrients, and contribute energy (calories) to the body. Despite acting as an enzyme or energy supplier, some proteins are also responsible for the transporting of vital materials and signals from extracellular to intracellular. Moreover, the protein formed antibodies and interferon can protect body from disease and viruses.

Rancidity represents the process of complete or incomplete oxidation or hydrolysis of unsaturated fats and oils presented in foods after exposing them to air, light, moisture or bacterial action. Specifically, oxidation or hydrolysis of fats resulting in short-chain volatile aldehydes esters, alcohols, ketones, and hydrocarbons, are characterized by unpleasant taste, flavour and odor. When these processes occur in food, undesirable detraction of nutritional value such as the oxidation of vitamins can result. Proper rancidity testing is an essential component in determining the shelf life of the product and the storage condition for foods. In this case, a rancidity testing, which can determines the level of oxidation in a sample, is needed to quality control your food products. To establish your product's shelf-life and make ensure that the bioactive ingredients in your product are shelf stable until the date of expiry, staffs from Alfa Chemistry conduct a series of analysis for the bioactive ingredients such as Vitamins, Amino acids, Chondroitin, Glucosamine, Sulfites and Caffeine.

As defined by FDA, additives represent any substances that are added to food and can be divided into direct additives that are intentionally added to foods for a specific purpose and indirect additives that are produced during food processing, packaging, or storing. Preservatives are special additives used to improve or maintain the consistency and quality of food by inhibiting the growth of bacteria, yeasts, and molds in foods. Routine food additives can be classified into antimicrobial agents, antioxidants, artificial colors, bleaching agents, artificial flavors and flavor enhancers, chelating agents, nutrient additives, thickening and stabilizing agents. In modern society and the competitive market, food additives and preservatives have a significant effect on ensuring your food supply, wholesomeness, normal pH, pleasant flavor and lovely appearance.
