Preparation of kelp red rice vinegar

Abstract

The invention relates to a preparation method of kelp red rice vinegar. According to the technical scheme, the preparation method comprises the following steps: 1) soaking cleaned kelp in water for 120 minutes to desalt kelp, cutting the kelp into sections, and adding a NaCO3 solution to prepare kelp slurry; gradually adding various comments of a compound enzyme for enzyme hydrolysis and then filtering by diatomite, and adding lactobacillus liquor and glucose for lactic acid fermentation to prepare a kelp lactic acid liquid; 2) by taking sticky rice as raw material, steaming and leaching, erecting a nest, brewing and carrying out alcoholic fermentation and carrying out acetic fermentation for three months to obtain red rice original vinegar; and 3) mixing the red rice original vinegar and the kelp lactic acid liquid, then adding a sesame alcohol soluble extracting liquid, and ageing and curing to obtain the kelp red rice vinegar. By taking kelp, sticky rice and red rice as main raw materials, small molecular final products such as amino acids, polypeptides, oligosaccharides and dietary fibers are brewed and produced by steps of lactic acid fermentation, alcoholic fermentation and acetic fermentation. The kelp red rice vinegar with a health-care function can be absorbed and utilized by a human body easily.

Description

technical field [0001] The invention belongs to the field of food processing, in particular to a method for preparing kelp-monascus vinegar with kelp, glutinous rice and red yeast rice as main raw materials. Background technique [0002] Kelp is a large brown algae with edible and medicinal uses. It contains phytonutrients and trace elements and nearly half of the carbohydrates are alginic acid, laminarin and mannitol, which have various physiological functions. Kelp extract is made from kelp, which is consistent with the original nutrient content of kelp, but its active ingredient content is much higher than that of kelp. It is a natural product extract with health care effects. Data show that kelp extract has multiple functions of lowering blood pressure, regulating blood lipids, delaying aging and anti-mutagenesis. The main methods of kelp extract are hot water extraction, alkali extraction, acid extraction, ultrasonic extraction and enzymatic method. Among them, the h...

Problems solved by technology

Among them, the hot water extraction method is simple and economical, but the yield and content of the extract components such as crude polysaccharides are low, and at the same time, the activity of polysaccharides will be destroyed if the temperature is too high; the alkali extraction and acid extraction methods can obtain higher extract components, but will cause Degradation of polysaccharide molecules in extract components; ultrasonic extraction can significantly increase the content of kelp extract components, but it is not suitable for large-scale industrial production, and some components such as crude polysaccharides have a small increase in yield; enzymatic method is a mild The method will not destroy the polysaccharide structure of the extract components, and can be used in industrial production on a large scale. Compared with the hot water method, the enzymatic method can significantly increase the yield of the extract components, and is an efficient method for obtaining biologically active extract components.
