A liquid nitrogen quick-freezing preservation method for fresh bamboo shoots. The method includes performing a coating treatment on cuts of fresh bamboo shoots, which reduces the moisture loss through the cuts, slows down the degree of lignification of the bamboo shoots, mitigates color changes at the cuts, inhibits excessively fast reproduction of microorganisms at the cuts and prevents invasion of microorganisms from the cuts, so that a decrease in nutritional value is reduced, the deterioration of the appearance quality of the bamboo shoots is mitigated, and the nutritional value and commodity value of the bamboo shoots are maintained. The method further includes an intermittent ultrasonic treatment on the fresh bamboo shoots, so that coating substances form films on the surfaces of the cuts more easily, preventing the fresh bamboo shoots from being eroded by microorganisms and preventing nutrient substances from being decomposed and utilized by the microorganisms.

Provided herein are antimicrobial coating compositions and food packaging materials coated therewith. The coating compositions include at least one antimicrobial active agent and a hydrophilic polymer, such that the active agent is immobilized within the composition.

A process for the production of a soft bakery product with a moisture content of at least 11%, which can be stored at room temperature for at least two months, while keeping its softness characteristics substantially unchanged is disclosed. The process includes the steps of: a) providing a semi-finished product obtained from a flour-based leavened dough; b) baking the semi-finished product in an oven, obtaining a bakery product having a moisture content of between 10% and 35% by weight; and c) injecting water or a hydroalcoholic solution into the product, in an amount such as to bring about an increase of at least 10% of the moisture content of the bakery product.

A compound and a method for prolonging shelf life of frozen aquatic products are provided. The compound includes: 15-20 parts by weight of modified carboxymethyl chitosan, 5-12 parts by weight of pectin, 2-5 parts by weight of oleic acid, 1-3 parts by weight of yeast selenium, 1-3 parts by weight of natamycin and 2-6 parts by weight of nisin. The method includes sequentially treating a frozen aquatic product under a mixed gas and soaking the frozen aquatic product in the compound. The method can obviously slow down the degradation and oxidative denaturation of protein in aquatic products during cold storage, thus effectively maintaining the activity of protein in the aquatic products and slowing down the deterioration of the aquatic products.

Disclosed is technology to solve the problem in a world that is inundated with microbes of keeping food fresher for longer and shelf-life extension to enhance food security and safety without refrigeration/freezing, chemical preservatives integrated into the food product and/or physically/chemically altering the food product. Aspects of the technology are directed at the three levels of the food delivery system; namely, supermarket style display ware, bulk packaging and overseas container. This technological problem is solved by situating on food contacting/abutting surfaces of display ware, bulk packaging and oversees containers an antimicrobe agent formulated as a composition comprised of (i) between about 0.25% (w/w) to about 0.75% (w/w) benzalkonium chloride; (ii) between about 0.02% (w/w) to about 1.00% (w/w) of a kill agent selected from the group consisting of hydrogen peroxide and phenoxyethanol; (iii) between about 0.25% (w/w) to about 0.75% (w/w) 3-(tri-methoxysilyl)propyldimethyl octadecyl ammonium chloride and (iv) between about 97.50% (w/w) to about 99.48% deionized water.

The invention relates to compositions comprising glycolipids and benzoic acid and/or sorbic acid.
