The present invention relates to preservation of meat products. In particular new additives are provided for effective inhibition or prevention of bacterial outgrowth in meat products. The present inventors found that a combination of carvacrol and a cationic surfactant was effective in the inhibition or prevention of bacterial outgrowth in meat products. The combinations, more in particular, proved to be effective at levels that do not result in significant effects on the flavor and/or taste of the products. The present inventors furthermore found that treatment of meat products with the combinations of this invention had a favorable effect on the visual appearance (color) of the meat products. The present invention provides preservative compositions, the use of thereof as well as the meat products containing them.

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.

The present invention relates to a composition for cryopreservation, comprising: a nucleic acid structure which comprises a scaffold nucleic acid folded at predetermined positions to form multiple strands, and a plurality of staple nucleic acids wherein at least a portion of a sequence thereof comprises a complementary sequence to that of the scaffold nucleic acid, which are bound to at least one of the strands of the scaffold nucleic acid to form a double strand; linkers coupled to at least one of single strands in the nucleic acid structure; and an anti-freezing peptide coupled to at least one of the linkers, so as to exhibit excellent freeze-protection effects, which in turn increase cell viability during cryopreservation of cells and tissues, while retaining original texture of food even when used for freezing the food.

The present invention discloses an antifreeze solution for food preservation, which comprises edible alcohol, propylene glycol, glycerin, calcium chloride, sodium chloride, amino acid, Antarctic krill protein hydrolysate with an average molecular weight of 50-100 KDa, surfactant and water, wherein the surfactant is one or more of phospholipid, Tween-20, Tween-60, and Tween-80; each component is food grade, and the mass percentage is expressed as follows: alcohol 15-30%, propylene glycol 10-30%, glycerol 2-15%, calcium chloride 1-10%, sodium chloride 3-10%, amino acid 0.1-0.15%, Antarctic krill protein hydrolysate 0.01-0.3%, surfactant 0.005-0.5%, and the balance is water. The antifreeze solution provided by the present invention can lower the freezing point, improve the heat transfer efficiency, inhibit the crystallization of antifreeze solution during the low temperature stirring process and improve the stability of the antifreeze solution.
