Preservatives

Introduction Product Name: NisinMolecular formula: C141H228O38N41S7 Nisin is a polypeptide material produced by Streptococcus lactis and is rapidly hydrolyzed into amino acids under the action of physiological pH and α-chymotrypsin. It does not change the body Intestine normal flora and the emergence of resistance problems such as other antibiotics, but not with other antibiotics cross-resistance, is a highly efficient, non-toxic, safe, high performance natural food preservatives. It can effectively inhibit the growth of Bacillus stearothermophilus, Bacillus cereus, Staphylococcus aureus, Listeria, Clostridium botulinum and other gram-positive bacteria of the vegetative cells and spores. Add food, can greatly reduce the food sterilization temperature, shorten the food sterilization time, so that the food to maintain the original nutrients, flavor, color, but also a lot of energy. Can be widely used in meat products, dairy products, vegetable protein food, canned food, fruit juice drinks and heat treatment of closed packaging food preservative preservation, but also can be applied to cosmetics and health care products and other fields. Streptococcus lactis can effectively inhibit the Gram-positive bacteria, especially for spore-forming bacteria have a good inhibitory effect. It is generally believed that gram-negative bacteria, yeasts and molds are ineffective, but under certain conditions (such as freezing, heating, low pH and chelating agent EDTA treatment), nisin can inhibit some salmonella spp, Shigella spp, Klebsiell spp and Escherichia coli.

Introduction Natamycin (Natamycin), also known as hamamycin or natamycin, is Streptomyces natalensis and Streptomyces chatanoogen and other Streptomyces fermentation of a polyene macrolide fungus inhibitor, is currently the only international Approved an efficient, broad spectrum, safe antifungal bio-food preservative that can be used to inhibit mold growth in molds and yeast. Products on the human body is very safe, reliable, and does not affect the product flavor. Has been approved by more than 40 countries, widely used in cheese, meat products, pastries, fruit juice, jelly, jelly, marinated products. China in 1996 approved the use of natamycin as food preservatives for cheese, meat products, Cantonese-style moon cake, pastry surface, fruit juice surface, easy moldy food processing containers surface, the residue should not exceed 10 mg.

Introduction Sorbic acid, or 2,4-hexadienoic acid, is a natural organic compound used as a food preservative. Sorbic acid has the chemical formula C6H8O2. Sorbic acid is a colourless solid that is slightly soluble in water and sublimes readily. Sorbic acid was first isolated from the unripe berries of the rowan tree (Sorbus aucuparia), hence its name.

Introduction Potassium sorbate is produced by neutralizing potassium hydroxide with asorbic acid. It is white or off white granular or powder. Potassium sorbate is used to inhibit molds and yeasts. It is considered to be safe because of its long term safety record and non-toxic profile, the toxicity is 1/40 times than sodium benzoate.

Introduction Calcium propionate is white crystalline, granular or crystalline powder, odorless or wih a slight acid odor, stable in heat and light, easy to dissolve in water.

Introduction Sodium Benzoate has been extensively used for many years as a preservative to control microbial growth. It is used in the food and beverage industries, pharmaceuticals, cosmetic products, corrosion inhibitors in automotive and other antifreeze products. A range of high quality benzoic acid grades are offered to meet the different demands.

Introduction Calcium Propionate Powder Sodium propanoate or sodium propionate is the sodium salt of propionic acid which has the chemical formula Na(C2H5COO).It is used as a food preservative and is represented by the food labeling E number E281 in Europe; it is used primarily as a mold inhibitor in bakery products. It is approved for use as a food additive in the EU, USA and Australia and New Zealand.

IntroductionGlucono delta-lactone (GDL), also known as gluconolactone, is a food additive with the E number E575 used as asequestrant, an acidifier,or a curing, pickling, or leavening agent. It is alactone of D-gluconic acid. Pure GDL is a white odorless crystalline powder.GDL is commonly found in honey, fruit juices, personal lubricants, wine and has been marketed for use in feta cheese.

Introduction Sodium acetate (CH3COONa) is the sodium salt of acetic acid. It appears as a colorless deliquescent salt with a wide range of applications. In industry, it can be used in textile industry to neutralize sulfuric acid waste streams and as a photoresist upon using aniline dyes. In concrete industry, it can be used as a concrete sealant to mitigate the water damage. In food, it can be used as a seasoning. It can also be used as a buffer solution in lab. In addition, it is also used in heating pads, hand warmers and hot ice. For laboratory use, it can be produced by the reaction between acetate with the sodium carbonate, sodium bicarbonate and sodium hydroxide. In industry, it is prepared from the glacial acetic acid and sodium hydroxide.
