Probiotic reinforced fermented seafood-flavor chili sauce and preparation method thereof
Technical Field
The invention belongs to the technical field of food processing, and particularly relates to a probiotic reinforced fermented seafood-flavor chili sauce and a preparation method thereof.
Background
The chili sauce is a sauce material prepared from chili, and is a common seasoning on a dining table. The commercial products are both oil and water products. The oil is prepared from vegetable oil and pepper, is bright red, is covered with vegetable oil, and is easy to store; the water-processed product is prepared by adding garlic, ginger, sugar, salt and other seasonings, pepper and water, and the product has bright red color and delicious taste and can be stored for a long time.
The fermented chili sauce is a lactobacillus fermented product with special flavor, has good sensory quality, low cost and relatively single flavor, and is convenient to eat. The chilli sauce produced by adopting a natural fermentation mode has the problems of long fermentation period, high nitrite content and the like,
the pepper is a common vegetable and seasoning in four seasons, belongs to solanaceae, is a herbaceous plant which can grow for many times within one year, has a large cultivation area in China, and is a common vegetable for four seasons in China. The edible chili can increase appetite, help digestion and improve the intestinal homeostasis, and the special substance components in the chili can accelerate the metabolism rate of a human body, improve the body cold and maintain the skin. Especially rich in vitamins, can reduce blood lipid content in blood and cholesterol, and has effects of preventing and resisting cancer, and controlling cardiovascular diseases. The red pigment in the red pepper is used as a rich source of vitamins and carotene, and the anti-aging capability of individuals can be enhanced by taking more red pepper in diet.
The shrimp paste is one of common condiments in coastal areas and countries in southeast Asia in China, is a mauve sticky food prepared by small shrimps such as the acete chinensis, the black shrimp and the like in an open multi-strain mixed fermentation mode under the condition of high salt, has delicious taste and unique flavor, contains a large amount of essential amino acids and mineral substances, has biological function activities of resisting oxidation, reducing cholesterol, reducing blood pressure, enhancing organism immunity and the like, and is deeply loved by coastal residents. The quality of the shrimp paste and the generation of characteristic flavor depend on the species composition and metabolic activity of microorganisms to a great extent, and along with the complex microorganism, physicochemical and biochemical changes in the fermentation process, substances such as protein, sugar, fat and the like are degraded and further reacted under the action of endogenous enzyme and microbial enzyme. On one hand, the reactions generate nutrient substances such as polypeptide, amino acid and the like and a plurality of flavor components, and influence the nutritional value and the flavor of the product; on the other hand, the texture of the product is changed, and the texture and the flowability of the product are influenced.
Probiotics grow in the human body environment, and exert beneficial effects on host organisms by regulating intestinal microbial flora. By regulating the immune system to improve the homeostasis of the human body, which is also called as the second genome of the human body, the probiotics promote the human body to utilize the nutrients in the food, so that the stability of the intestinal flora of the human body can be maintained, and the immunity of the human body can be regulated.
The lactobacillus can generate a large amount of organic acid in the fermentation process, which is very beneficial to the fermentation process of fermented foods, the organic acid generated in the fermentation process reduces the pH value of the fermented products, thereby inhibiting the infection of other mixed bacteria, the lactobacillus can be commonly used as the main fermentation strain for the fermentation of pickled vegetables, simultaneously, a large amount of bacteriocin can be generated in the fermentation process, the bacteriocin has larger influence on the growth inhibition of other mixed bacteria, especially, the nitrite reductase generated by lactobacillus plantarum can reduce the nitrite content in the fermented foods, shorten the fermentation period and improve the fermentation efficiency. Its metabolic mechanism can produce a large amount of lactic acid and acetic acid, an interspecific heterosexual fermentation strain, can be propagated at 15 deg.C; lactobacillus acidophilus is a homofermentative strain, a microaerophilic organism that ferments sugars to lactic acid. Is suitable for growth at a lower pH value, and the lactobacillus acidophilus plays a role in the later fermentation stage to become a dominant strain.
The sweet fermented glutinous rice is commonly called fermented glutinous rice, is brewed by taking glutinous rice as a raw material and sweet fermented glutinous rice as a strain through fermentation, is sour, sweet and tasty, has attractive flavor and rich nutrition, and has medicinal and health-care effects. The sweet distiller's yeast can generate various enzymes such as amylase, saccharifying enzyme, protease, metabolite saccharide, organic acid, polypeptide, amino acid, alcohol, ester, etc., which also make the sweet fermented glutinous rice have its special flavor and convert substances which are not easily absorbed by human body into easily absorbable form. The mould and yeast in the sweet fermented glutinous rice take sugar as nutrient substances to generate ethanol, and the ethanol is combined with organic acid to generate ester, so that the flavor of the chili sauce is added.
