Yoghourt with iron supplementing function and preparation method thereof

Abstract

The invention discloses yoghourt with an iron supplementing function. The yoghourt is prepared from raw materials such as raw milk, probiotics N1115 bacterial powder containing iron lactate, inulin and white granulated sugar. A preparation method for the yoghourt comprises steps of mixing, homogenizing, sterilizing, cooling, inoculating, fermenting, emulsion-breaking, cooling, bacterial powder adding and the like. The probiotics N1115 bacterial powder containing iron lactate is adopted, so that mouthfeel of the yoghourt is not reduced, and the iron supplementing function is achieved. The preparation method effectively utilizes lactic acid generated in a fermentation process to generate the probiotics N1115 bacterial powder containing iron lactate, and the prepared yoghourt has the effect of supplementing an element iron; and generated ferrous lactate has stimulation on intestines and stomachs of people, and takes along with probiotics or yoghourt to reduce discomfort in intestines andstomachs of patients. The preparation method is used for preparing the yoghourt which has functions of improving iron element deficiency and supplementing iron.

Description

technical field [0001] The invention belongs to the field of food, and relates to a yogurt and a preparation method thereof, in particular to a yogurt with an iron supplement function and a preparation method thereof. Background technique [0002] Yogurt starter is the key raw material for making yogurt, and its strain characteristics and other material contents affect the flavor, taste and functionality of yogurt. With the increasing level of people's consumption, consumers' demand for yogurt functionality is gradually emerging. [0003] Iron is an essential metal element for the human body. Iron is the main component of hemoglobin (the main oxygen-carrying component in red blood cells) and myoglobin (the part that stores oxygen in muscle cells and supplies oxygen during muscle exercise). Iron deficiency can cause anemia and other health problems. Ferrous lactate is used as a human iron supplement because it is more stable and soluble in water than other ferrous compounds...

AI Technical Summary

Problems solved by technology

Generally speaking, ferrous lactate is obtained by adding refined iron powder to lactic acid and then crystallizing and drying, but when it is made alone, the amount of lactic acid is relatively large

However, a large amount of lactic acid produced during the fermentation of Lactobacillus paracasei N1115 will be neutralized by adding lye to inhibit the growth of lactic acid bacteria, which will not only increase the cost but also cause a lot of waste of lactic acid
