Preparation method of yogurt ice cream containing dietary fibers

Abstract

The invention provides a preparation method of yogurt ice cream containing dietary fibers. The method comprises the following steps: weighing skimmed milk powder, ultramicro bamboo shoot powder, palmoil, beta-cyclodextrin, water, an emulsifying agent, a stabilizing agent and a food antioxidant according to a formula; then uniformly mixing and stirring the weighed raw materials and performing homogenization, sterilization and aging to obtain an ice cream mixed material; and adding an effervescent agent and yogurt to the ice cream mixed material, performing uniform stirring and then performingfilling and hardening to obtain probiotic ice cream. According to the method, the effervescent agent and the yogurt are added to the aged ice cream mixed material, the effervescent agent disintegratesin the raw materials and generates bubbles, so a good structure with densely spread fine bubbles, increased volume and loose condensed tissues is formed, also the viable count of probiotics in the ice cream is ensured, and a technical problem that the viable count of probiotics cannot reach a minimal effective dose by adopting freezing operation in the prior art is overcome; and the method provided by the invention is simple in operation compared with the prior art and promotes application of probiotics in ice cream.

Description

Technical field [0001] The invention is in the field of ice cream food. In particular, it relates to a preparation method of dietary fiber yogurt ice cream.

Problems solved by technology

However, the following technical difficulties exist in the probiotic ice cream industry. One is that the probiotic species in the existing probiotic ice cream is single and the probiotic functions are limited. This application only added Lactobacillus in the ice cream raw material, the notification number is CN1919031, the name is a kind of yogurt soft ice cream powder and the method for preparing ice cream with it, this patent is to add lactic acid bacteria into the ice cream in the form of yogurt powder, Similarly, only a single genus of bacteria is used; the second is that the aging and freezing of probiotic ice cream during the preparation process have the greatest impact on the activity of probiotics, and the aeration and whipping during freezing will cause the loss of 20% to 50% of the probiotics. More, so that the content of live bacteria in ice cream does not reach the minimum amount that can play a positive role, and probiotic ice cream loses its meaning
