Embodiment 1

[0035] Press and dehydrate 5kg bacterial cellulose product, dry it in an oven at 80°C to obtain 100g of dried bacterial cellulose, then use a pulverizer to pulverize the dried bacterial cellulose, pass through a 150-mesh sieve, and set aside. Weigh 76g of white granulated sugar, 1g of ammonium bicarbonate, 2g of baking soda, 2g of table salt, 1g of flavoring, and add 231g of water to mix evenly to obtain a premix; Mix 80g of vegetable oil, and then mix with the premix evenly, then add 500g of flour, 30g of bacterial cellulose dry powder and continue to stir for 20-50min until uniform. Put it aside for 20 minutes; then roll it 10 times, press the dough into a 1.6mm sheet, and mold it; use an oven for baking, the bottom fire temperature is 180°C, and the surface fire temperature is kept at 160°C for 4 minutes; then 180°C ℃, 4 minutes; the last 200 ℃, 3 minutes; after that, the baked biscuits are naturally cooled for 10 minutes, and then sealed and packaged (preferably packaged a...

Embodiment 2

[0037] Weigh 5kg of gelatinous coconut bacterial cellulose or the leftovers of coconut fruit enterprise processing products and remove part of the water by pressing until the quality of the bacterial cellulose gel is 200-400g. After homogenizing by a homogenizer, collect the homogenate for later use; 76g of sucrose, 5g of ammonium bicarbonate, 10g of baking soda, 1g of table salt, 8.5g of food flavoring, add 100-200g of water and mix evenly to obtain a premix; Mix 80g, then mix with the premix evenly, then add 500g flour, then add 200-400g coconut fruit homogenate and continue to stir for 30min until uniform. Stand at 35°C for 15 minutes; then roll the dough 10 times, press the dough into 1.6mm thin slices, and mold it; use an oven to bake, the primer temperature is 180°C, and the surface fire temperature is kept at 160°C for 4 minutes ; then 180°C, 4 minutes; finally 200°C, 3 minutes; after that, the baked biscuits are naturally cooled for 10 minutes, and then airtightly pack...

Embodiment 3

[0039] (1) Take 1000 g coconut bacterial cellulose, press to remove half of the water, stir in a high-speed homogenizer (22000 rpm) and pulverize the homogenate for 30 minutes to obtain a coarse homogenate;

[0040] (2) The homogenate is filtered once with a single layer of ordinary gauze (20-30 mesh), and the unfiltered bacterial cellulose is returned to the homogenizer to continue the homogenization, and then filtered, and the operation is repeated until all can be filtered, and the homogenate is collected ;

[0041] (3) Dilute the homogenate with deionized water at a ratio of 1:4, spray dry (inlet temperature 140°C, pump speed 20 r / min, air flow rate 16 L / min), collect bacterial cellulose powder and glass Bacterial cellulose powder attached to the wall.

[0042] (4) Weigh 76g of sucrose, 5g of ammonium bicarbonate, 10g of baking soda, 1g of salt, 50g of milk powder, 8.5g of flavoring, add 373-497g of water and mix well to obtain a premix;

[0043] (5) Then, prepare the do...

Abstract

The invention relates to a high-dietary-fiber biscuit containing bacterial cellulose, which is prepared by adding 1-70 percent by mass of bacterial cellulose (such as coconut fruit or coconut fiber fruit, and the like generally called by the food industry) to common biscuit. A preparation method of the high-dietary-fiber biscuit containing the bacterial cellulose comprises the following steps of:(1) preparing a premix compound; (2) conditioning dough; (3) carrying out impressing and forming on biscuit; and (4) baking the biscuit. By adding the bacterial cellulose to the biscuit, the invention has more exquisite taste and stronger capacity of adsorbing harmful substances in human bodies compared with the general dietary-fiber biscuit. The novel dietary-fiber biscuit not only can improve the nutritive value of the biscuit and upgrade the functional needs of the product, but also has the advantages of simple process, convenient operation, less equipment investment, easily obtained low-price raw materials and favorable economic benefits and application prospects, and is very suitable for industrialized production.

Description

technical field [0001] The invention belongs to the field of dietary fiber biscuit and its preparation, in particular to a high dietary fiber biscuit containing bacterial cellulose and a preparation method thereof. Background technique [0002] Dietary fiber can balance human nutrition, regulate body functions, promote intestinal peristalsis, facilitate waste discharge, reduce absorption of harmful substances, and prevent obesity. It is known as the "seventh largest nutrient" needed by the human body. In recent years, with the development of my country's economy and the improvement of people's living standards, great changes have taken place in people's eating habits, resulting in an increase in many diseases related to insufficient dietary fiber intake, such as obesity, hypertension, coronary heart disease, diabetes and colon Cancer has become a major disease that endangers the health of our people. In this background, the study of dietary fiber and the development of dieta...
