This patent application claims the benefit and priority of Chinese Patent Application No. 202110278010.1, filed on Mar. 16, 2021, the disclosure of which is incorporated by reference herein in its entirety as part of the present application.
The present disclosure belongs to the technical field of food processing, and in particular relates to a preparation method of a low-sugar whole potato flour energy bar.
With the acceleration of the pace of life, people are increasingly inclined to choose foods that can quickly take in energy, supplement nutrients and regulate body functions in addition to regular diets. The energy bar is a convenient, instant, nutritious bar-shaped food that can quickly replenish energy, and has the advantages of small size, light weight, and convenience to carry, and is welcomed by consumers. In the early 1990s, energy bar food began to emerge in developed countries such as Europe and the United States. In the past 10 years, they have grown from more than 10 varieties to more than 500 ones. Their functions, packagings, and flavors are dazzling. Energy bars have developed from athlete special food into a large category of general functional food. In 2018, the output value of energy bars reached RMB 9 billion in China, and the overall market size reached about RMB 30.5 billion. Therefore, in response to different ages, different occupations and other special nutritional needs, the development of full nutritional energy bars with rich taste, compact packaging, convenience to carry, high-quality ingredients, comprehensive nutrition and multiple body regulation functions has a very broad market prospect and economic benefits.
Traditional energy bars generally use sucrose and maltose as binders, resulting in energy bars that have high hardness, high dryness, poor cohesiveness, poor taste, sticky teeth, and the like, and excessive sugar intake can cause dental caries, obesity and other health problems.
Use of sucrose and maltose as binders in the existing energy bars leads to high hardness and adhering tooth in energy bars. In view of the problem, an objective of the present disclosure is to provide a preparation method of a low-sugar whole potato flour energy bar. Starting from improving binder preparation, the method improves the taste of the energy bar.
To achieve the above objective, the present disclosure adopts the following technical solution:
A preparation method of a low-sugar whole potato flour energy bar is provided. Using starch gel and sugar alcohol as binders, whole potato flour and dried honey powder are added to prepare the energy bar, including the following steps:
step 1, starch gelatinization: gelatinizing the starch and storing at 90° C. for later use;
step 2, sugar alcohol dissolution: putting the sugar alcohol in a jacketed kettle, heating at 100-120° C., and constantly stirring until the sugar alcohol is dissolved completely, to obtain a sugar alcohol solution;
step 3, binder preparation: mixing gelatinized starch and the sugar alcohol solution in a mass ratio of 2:1 to 1:1, constantly stirring, boiling a resulting mixture at 120-140° C. in an open manner until water evaporation, and cooling the mixture to 90° C. to obtain the binder; and
step 4, energy bar production: preprocessing the adjuvants according to properties thereof, mixing a binder obtained in step 3 with preprocessed adjuvants in a mass ratio of (40-70):(30-70), stirring evenly, and conducting mold pressing or cool forming to obtain the energy bar.
Further, the starch in step 1 may be selected from the group consisting of corn starch, cassava starch, potato starch, and modified starch acceptable in food; further, the modified starch may be selected from the group consisting of acidified starch and crosslinked starch.
Further, the starch gelatinization in step 1 may be specifically achieved by: mixing the starch with water in a mass ratio of 1:6 to 1:10, sealing and gelatinizing the starch in boiling water for 30-60 min.
Further, the sugar alcohol in step 2 may be selected from the group consisting of maltitol, sorbitol, and a mixture of both, and the maltitol and the sorbitol may have a mass ratio of 2:1 to 3:1 in the mixture.
Further, the gelatinized starch and the sugar alcohol solution in step 3 may have a mass ratio of 1.5:1.
Further, stir-fried whole potato flour in step 4 may be commercially available whole potato flour stir-fried for 5-10 min.
Further, the adjuvants may be the whole potato flour and the dried honey powder, the whole potato flour in step 4 may be processed by stir-frying, and the binder, the stir-fried whole potato flour, and the dried honey powder may have a mass ratio of (40-70):(30-50):(3-5).
The present disclosure has the following beneficial effects: In the present disclosure, the sugar alcohol replaces sucrose and binds to the starch gel to prepare the binder, and the low-sugar whole potato flour energy bar is prepared in combination with nutrition characteristics of the whole potato flour; the product is proper in hardness, strong in cohesiveness, good in taste and non-sticky to teeth.
