The present application belongs to the technical field of instant meat product processing, and discloses an instant ham and a preparation method. The method comprises low-salt pickling and semi-mature fermentation, high-temperature three-gradient fermentation after slicing and addition of probiotics, and the combination of vacuum temperature-changing fermentation ripening and bacteriostatic process, and processes the instant ham which is quickly fermented and matured, reduces the content of salt, inhibits the growth of rancidity and harmful bacteria, and is convenient to eat after opening the bag. The present application first proposes that the meat product after rapid fermentation is vacuum packaged and then subjected to special vacuum high-temperature fermentation ripening and bacteriostatic treatment at a high temperature of 49-52 DEG C. The process can not only significantly shorten the fermentation time to about 110-120 minutes, but also basically kill the non-sporulated vegetative microorganism cells in the vacuum-packaged ham, while allowing the probiotics to be retained to a certain extent and avoiding the pollution of microorganisms and other harmful substances thereafter. The "fast, low-salt, flavor, instant" ham product prepared by the present application technology cannot be realized by the existing ham fermentation technology.

The invention is suitable for the technical field of livestock feed, and relates to a method for improving the quality of feed triticale silage, which comprises the following steps: (1) mixing: uniformly mixing triticale with a compound bacteria solution with the concentration of 1-4% to obtain a mixture, wherein the compound bacteria consist of feruloyl esterase-producing lactobacillus plantarum with the living cell number range of 106-108 CFU / g and bacillus velezensis with the living cell number range of 106-108 CFU / g; and (2) anaerobic fermentation: performing anaerobic fermentation on the mixture in the step (1) under the conditions that the temperature is 25-30 DEG C and the relative humidity is 40-50% for 60 days to obtain the triticale silage. The method for improving the silage quality of the feed triticale has the beneficial effects that the degradation of wood fibers is improved, the content of soluble carbohydrates and lactic acid is increased, the content of ammoniacal nitrogen is reduced, and harmful bacteria are inhibited, so that the silage fermentation quality of the triticale is improved.
