Technical field
The invention belongs to food technology fields, and in particular to one kind is using salted vegetable with high salt as Raw material processing fire convenient for production The crisp technology of guarantor of pot vegetables packet.
Convenient chafing dish nearest two, three years, with the quickening of wage-earners' work rhythm and the development for the fast food that works, facilitates fire Pot also high speed development therewith, the vegetables packet in convenient chafing dish is using the vegetable dish of chafing dish shop brush chafing dish as raw material (fresh vegetables or salt Stain vegetables mainly have lotus root piece, numb sliced bamboo shoot, potato chips, agaric slice, kelp piece, carrot slice, needle mushroom, fresh corn etc.), warp Arrangement selects, cutting, and pretreatment (protect crisp, protect crisp desalination) cooks (water-removing, curing), brewed tasty, packaging, the processes such as sterilization It is process;This product salinity is 1.5%-3.5%, and pH value 4.6-5.2%, color is vegetables true qualities, and brittleness keeps vegetables itself It is tender crisp, taste is salty fresh agreeable to the taste.
Crisp in taste is important aesthetic quality's index of carrot piece and numb sliced bamboo shoot, it is one kind when product is edible Brittleness substance in tooth sense reaction, carrot piece and numb sliced bamboo shoot is pectin substance, the pectin substance in carrot piece and numb sliced bamboo shoot There are three types of states: i.e. " protopectin, pectin, pectic acid ", protopectin is the component part of cell wall mesoglea, not soluble in water, often It is combined into pectin fiber in fiber, makes tissue that there is certain intensity and density;Pectin there are in cell liquid, it is water-soluble without It is easy alcohol, bonding operation once loses, organizes soft immediately;Pectic acid is not soluble in water, in carrot piece and numb sliced bamboo shoot tissue Protopectin is hydrolyzed into pectin and pectic acid under the action of pectin decomposing enzyme, when boiling altogether in the solution of water and acid, is decomposed into Pectin, pectin in the presence of alkali, are decomposed into pectic acid, and brittleness reduces.
Pectic acid can form insoluble pectate (Tang Chunhong and Luo Yuanqiang, 2001) with combinations such as calcium and magnesium ions, These salts can play the role of adhesion in space between cells, and pickled product is made to keep brittleness.Dong's congruence (2002) research discovery is used 0.10%CaCl2It is added in the sauce of low-salt pickle for curing agent, the tissue quality and hardness that product is intrinsic can be kept.It is yellow 0.10% CaCl is added in industry biography etc. (2006) research discovery during salting down in advance2The brittleness of pickles can preferably be kept.Guo Yu The large-scale radish that Rong etc. (2005) are introduced using Japan is raw material, using CaCl2 as curing agent, the results showed that 2% CaCl2It is dense It is best to spend treatment effect, 3% has a harsh feeling.Perhaps the diligent CaCl for waiting (2007) to use various concentration is learned2Solution soaks oenanthe stolonifera Bubble finds CaCl2Solution concentration impregnates 30min at 0.2%, can improve the tender and crisp quality of oenanthe stolonifera flexible packing products.It grinds above Study carefully and shows to add pectic acid that certain calcium salt can be such that pickled product itself contains and form pectate with calcium binding to reach Protect crisp purpose, but CaCl2Usage amount is excessively high to generate bitter taste.
