Abstract

The invention relates to the technical field of food processing, and discloses a preparation method of lactic acid flavored toffee. Lactic acid toffee is obtained by further processing in a manner forpreparing semi-finished products through fermentation, components in grapes are sufficiently used, nutrient components in the toffee are increased, and the toffee has high nutrient value. Through refrigeration, acetaldehype and diacetyl in the fermentation semi-finished products achieve the best cooperation effect, wherein the acetaldehype content is 18.85-19.85 micrograms / gram, and the diacetylcontent is 3.15-1.30 micrograms / gram. The prepared lactic acid flavored toffee has great sour and sweet mouth feel and is rich in fragrance, smooth without sticking and greasy feeling, and high in refreshing feeling.

Description

technical field [0001] The invention belongs to the technical field of food processing, and in particular relates to a preparation method of lactic acid-flavored toffee. Background technique [0002] As one of the two traditional pillar snack industries in my country, the candy industry has maintained rapid growth and its potential market share has continued to expand. In the past five years, my country's candy market has maintained an annual growth rate of 8%-12%. In 2011, the scale of my country's candy industry has reached 62 billion yuan. Among them, toffee is a semi-soft candy with a relatively loose structure. The section of the sugar body has tiny pores, with toughness and elasticity, chewing resistance, soft and delicate taste. The average water content of toffee is 5-8%, and the reducing sugar content is between 14-25%. [0003] As the market continues to expand, people have access to more and more choices, and the confectionery industry is highly competitive, it...
