Description

Production process of condensed milk cap capable of improving fluffiness rate and durability

Technical Field

The invention relates to the technical field of dairy product processing, in particular to a production process of a condensed milk cover for improving the fluffiness rate and the durability.

Background

The milk cover is a milk product prepared by blending pure fresh milk, the milk cover is prepared by a plurality of methods, and at present, in beverage stores or processing industries, the milk cover powder is widely applied due to the convenience, and is mainly prepared into powder by using creamer, granulated sugar, milk powder, a stabilizer and spice, although the taste is not as good as the milk cap prepared by fresh milk, the taste is also excellent, and the milk cap powder is also called milk soaking powder, or named as the milk powder of the white-flaebred-bell, the main component is the non-dairy creamer, the milk powder is suitable for most drinks (tea, coffee, etc.), only 40-50ml of milk cap is needed to be added on the drinks, a new drink variety is created, the milk cap is generally divided into original taste and cheese, the original taste can be matched with sweeteners with various tastes, for example, condensed milk or sugar is added to increase the sweetness, so that other tastes are mixed, and the trend of the milk-covered tea is popular in the aspect of drinks.

The method for manufacturing the milk cap by using the milk cap powder is that stable and uniform milk bubbles can be formed by adding water and beating the milk cap powder, the milk cap powder is mostly used for manufacturing the milk cap in the existing beverage shop, but certain problems exist in the manufacturing process, the taste is not good, the specific expression is that the fluffiness rate of the milk cap is not high, the shape-preserving duration is not long, and the problem which is difficult to avoid in the existing manufacturing process is solved, firstly, when the milk cap powder and water are added, the beverage shop selects a one-time pouring mode for saving time and abandoning a component gradual adding mode, so that the milk cap powder and the water condensate are inevitably led to generate certain coagulations, even if the milk cap powder and the water are beaten, certain granular feeling is inevitably generated, the taste is influenced, the concentration is also influenced, the proportion of the milk cap is unbalanced, and meanwhile, in the beaten container, relatively strong liquid tends to be close to the inner wall of the container under the beating of the beaten container, when the milk cover is used for beating, the direction needs to be adjusted manually, so that certain beating dead angles are avoided, uneven beating is caused, and the integral filling power and durability of the milk cover are also influenced.

In connection with the problems set forth above, the reasons are summarized as follows:

1. when the raw materials are added, the raw materials are not sufficiently premixed, resulting in more or less uneven mixing or coagulation to solids.

2. When the mixture is beaten and sent out, the mixture is dumped at one time, and certain dead angles exist in the beating and sending out process, so that the beating and sending out are not uniform, and the quality of products is influenced.

Therefore, a production process of the condensed milk cap for improving the fluffiness rate and the durability is provided to solve the problems.
