Mold, inhibition

Natamycin (Pimaricin) has been approved for use on the surface of cheese and cheese slices for mold inhibition (47). 

Use Mold-inhibiting additive in bread, other foods, tobacco, pharmaceuticals, medicine (antifungal agent). 

Borates (such as boric acid, borax, disodium octaborate tetrahydrate) have been used as broad-spectrum wood preservatives for over 50 years. Zinc borate has a shorter history as wood preservative, but it is well accepted in that capacity. There is a belief that, generally, zinc borate is more effective against fungal decay compared to mold inhibition, though systematic studies, using different composite materials, are apparently lacking. 

Comments Commonly encountered in agar plates made from a soil Infusion otherwise rarely encountered In sterile culture. An occasional contaminant of mushroom beds (compost), Lipstick Mold Inhibits primordia formation and development. With the advent of concrete composting surfaces and peat based casings, this contaminant has been virtually eliminated from modern mushroom farms. 

The method under discussion creates a moderate temperature regime when molding inhibited films thus eliminating their thermal destruction and VCI losses on evaporation. 

As with straight soybean glues, the low-blood-content formulation requires a mold-inhibiting ingredient to meet plywood performance standards, whereas the high-blood-content glue does not [24]. 

Antibiotics. In 1918 an influenza epidemic killed twenty million people worldwide, one-half million in the United States alone. Venereal diseases were incurable. Until the 1950s polio crippled millions. Discovering medicines was only part of the solution. After it was observed that a mold inhibited bacterial growth in a Petri dish, chemical engineering developed the technology to ultimately produce millions of pounds per year of penicillin. Chemical engineering made possible the mass production of medicines and the subsequent availability to people worldwide. 

Antibiotics are toxic water-solubie compounds produced by molds or bacteria which inhibit the growth of other microorganisms. For an antibiotic to be useful in medicine it should have a high order of selective toxicity to microorganisms which are pathogenic to man. Al-... 

Tack. Tack causes layers to adhere when they are pressed together. This property can be reduced by employing fillers with a finer psd or by dusting the stock with a laminar filler such as mica. In a related value, fillers such as mica can inhibit adhesion to the mold during processing.

Seafood. Sorbates are used to extend the shelf life of many seafood products, both fresh and processed (103,104). For smoked or dried fish, an instantaneous dip in 5 wt % potassium sorbate or a 10-minute dip in 1.0 wt % potassium sorbate prior to drying or smoking inhibits the development of yeast and mold (105,106). For fresh fish, sorbates can be incorporated at approximately 0.5 wt % into the ice, refrigerated seawater, or ice-water slush in... 

Extrusion Resins. Extmsion of VDC—VC copolymers is the main fabrication technique for filaments, films, rods, and tubing or pipe, and involves the same concerns for thermal degradation, streamlined flow, and noncatalytic materials of constmction as described for injection-molding resins (84,122). The plastic leaves the extmsion die in a completely amorphous condition and is maintained in this state by quenching in a water bath to about 10°C, thereby inhibiting recrystallization. In this state, the plastic is soft, weak, and pHable. If it is allowed to remain at room temperature, it hardens gradually and recrystallizes partially at a slow rate with a random crystal arrangement. Heat treatment can be used to recrystallize at controlled rates. 

Sodium or potassium benzoate at a concentration of 0.05% is a universally used preservative agent active against yeast and mold. At higher concentrations benzoate is also effective against bacteria. It is most effective at a pH between 2.0 and 4.0. Sodium or potassium sorbate inhibits the growth of yeast and mold and is most effective below pH 6.5. 

Evaporation gives the salt sodium acetate, which contains Na+ and CH3COO ions. Many of the salts of carboxylic acids have important uses. Sodium and calcium propionate (Na+ or Ca2+ ions, CH3CH2COO ions) are added to bread, cake, and cheese to inhibit the growth of mold. 

Some simple foods can be preservatives in their own right. Honey, salt, sugar, lactic acid, and vinegar are all examples of foods that inhibit microbial action. Some health professionals recommend consuming phytoestrogens from foods such as soybeans to achieve various health benefits. The phytoestrogens in the paraben family, found in blueberries, kill molds and fungi and are often added to food as preservatives. 

Potassium sorbate is a polyunsaturated fatty acid salt. It is used to inhibit molds, yeasts, and fungi in many foods, including cheese, wine, and baked goods. It is the potassium salt of sorbic acid. 

Sodium benzoate is used as a broad-spectrum antimicrobial, inhibiting bacteria, molds, and yeasts. The high acid content of the soft drink is necessary for the preservative action. Sodium citrate buffers the acids, so the pH stays low (acidic). It also emulsifies any fats or fat-soluble compounds in the flavorings, keeping them in solution.
