Abstract

The invention discloses a fat substitute and a preparation method thereof, belonging to the technical field of food processing. The high-ester lemon pectin is used as a raw material and is compounded with other hydrophilic colloids to prepare gel, and the gel is sheared and micronized at a high speed to form the fat substitute which has a fine and smooth mouthfeel similar to that of the fat substitute. The fat substitute produced by the invention can be applied to baked products to partially substitute fat.

Description

Preparation method of fat substitute using lemon pectin as matrix
Technical Field
The invention relates to a preparation method of a fat substitute taking lemon pectin as a matrix, which comprises a preparation formula and process optimization conditions and belongs to the technical field of food processing.
Background
Fat is a necessary nutrient substance for human bodies, but excessive intake of fat can cause hyperlipidemia, obesity and cardiovascular and cerebrovascular diseases, so with the development of times and improvement of living standard, people turn from the consideration of the problem of satiety to the attention of health problems, and consider that the aim of reducing fat intake is achieved by reducing the fat content in diet, but the taste and flavor of food are seriously affected by simple reduction of fat, so fat substitutes begin to appear and are researched and applied by people.
Fat substitutes in general can be divided into two broad categories: a kind of fat substitute is prepared by using fat as matrix, and is also called fat substitute. The fat substitute is a substance which is obtained by taking fatty acid as a substrate through esterification, has the property similar to that of fat and can completely replace the fat. Another type is a fat substitute based on protein or carbohydrate, also known as simulated fat. Such fat substitutes mimic part of the properties of fat during use and do not completely replace fat. Carbohydrate-based fat replacers are currently the most widely used fat replacers, mainly because they have no side effects and are easily digestible.
Pectin, a high molecular weight carbohydrate, is often added to food as a thickener to increase the viscosity of the food. Moreover, pectin, a type of dietary fiber, has been shown to inhibit the absorption of lipids, thereby reducing calorie intake. Although some researches on preparing fat substitutes by taking pectin as a raw material are already carried out at home and abroad, no research is yet carried out on preparing the fat substitutes by taking high-ester lemon pectin as a raw material, and if the fat substitutes prepared by taking the lemon pectin as the raw material can replace part of fat in baked foods, the method has important significance for improving the comprehensive utilization rate of the lemon pectin.
Disclosure of Invention
The invention aims to provide a preparation method of a fat substitute taking lemon pectin as a matrix, and the obtained fat substitute can simulate the smooth and fine mouthfeel of fat.
1. A fat substitute based on lemon pectin, the preparation method comprises the following steps:
(1) weighing 1-1.8% of high-ester lemon pectin and 30.7-35.9% of deionized water, keeping in a water bath at 80 ℃ for 30min at constant temperature, supplementing deionized water at the same temperature to keep the concentration of the pectin solution, adjusting the pH to 2.7-3.1 by using 12.5% citric acid, adding 0.1-0.5% of CMC, mixing, adding 63-67% of sucrose, stirring until the sucrose is completely melted, taking out, and cooling to room temperature to obtain pectin gel;
(2) high-speed shearing and micronizing: shearing and micronizing the pectin gel prepared in the step (1) by using a high-speed shearing machine;
2. in the step (1), the pectin is high-ester lemon pectin, and the esterification degree is 67%;
3. in the step (2), the shearing speed is 10000r/min, and the shearing time is 10 min.
The invention has the beneficial effects that: the fat substitute prepared by the method is milk white, has a color similar to that of fat, has no bad smell, can simulate the rheological property of fat, can improve the water holding capacity and sensory characteristics of food, can be used as the fat substitute to replace part of fat in baked food, increases the food utilization value of lemon pectin, and creates feasible conditions for the production of low-fat food. The method has scientific and reasonable design, simple and easy operation, no influence on the environment and can improve the comprehensive utilization value of the lemon and the lemon pectin.

Detailed Description
Example 1: preparation of fat substitute using lemon pectin as matrix
Weighing 1.4% of high-ester lemon pectin and 33.1% of deionized water, keeping the mixture in a water bath at 80 ℃ for 30min at constant temperature, supplementing deionized water at the same temperature to keep the concentration of the pectin solution, adjusting the pH to 3.0 by using 12.5% of citric acid, adding 0.5% of CMC, mixing uniformly, adding 65% of sucrose, stirring until the sucrose is completely melted, taking out, cooling to room temperature, and obtaining pectin gel; shearing and micronizing the obtained pectin gel with high speed shearing machine at shearing speed of 10000r/min for 10min to obtain fat substitute with rheological property similar to that of fat, and the particle size distribution diagram and gel texture are shown in fig. 2-3.
Example 2: application of fat substitute using lemon pectin as matrix
The fat substitute obtained in example 1 was used to replace 40% of butter in the cookie to prepare a cookie, and the prepared cookie was subjected to sensory evaluation according to the sensory rating criteria of table 1 and compared with a full-fat cookie to which no fat substitute was added, and the sensory rating results are shown in table 2, which revealed that the cookie taste containing a fat substitute based on lemon pectin was substantially the same as the full-fat cookie.

The formula of the cookie biscuit containing the lemon pectin fat substitute is as follows (in percentage by mass): butter 18%, fat substitute 12%, maltitol 5%, sugar powder 4%, edible salt 0.1%, milk 9%, and low-gluten flour 51.9%. The full-fat cookie is not added with fat substitutes, the butter consumption is 30 percent, and the other conditions are the same as those of the low-fat cookie. The baking conditions are that the oven is preheated at 170 ℃, and the baking is carried out for 18min with the upper fire and the lower fire at 170 ℃.
