Problems solved by technology

However, chitosan oligosaccharides contain amino groups and carbonyl groups, and carbonyl ammonia reactions (Maillard reactions) will occur during processing and storage, causing color deepening and reduction of nutritional functionality. How to establish a stable technology to protect chitosan oligosaccharides is a solution The key to the problem of poor stability of chitosan oligosaccharides

Embodiment 1

[0027] After 4 parts of chitosan oligosaccharides and 5 parts of sodium stearoyl lactylate are mixed uniformly, 91 parts of butter are added and mixed uniformly, and the homogenizer is homogenized to obtain the chitosan oligosaccharide-butter mixture;

[0028] Add 100 parts of low-gluten flour, 10 parts of egg liquid, 2 parts of white sugar powder, 1 part of table salt, 20 parts of chitosan oligosaccharide-butter mixture to the dough mixer, add 10 parts of water and knead into a dough. After standing for 20 minutes, roll it with a mold After molding, put it in an oven and bake at 160°C for 30 minutes, and cool naturally to obtain a stable chitosan oligosaccharide biscuit.

Embodiment 2

[0030] After 10 parts of chitosan oligosaccharide and 5 parts of sodium stearoyl lactylate are mixed uniformly, 85 parts of butter are added and mixed uniformly, and the homogenizer is homogenized to obtain chitosan oligosaccharide-butter mixture;

[0031] Add 100 parts of low-gluten flour, 15 parts of egg liquid, 2 parts of white sugar powder, 0.5 parts of salt, 10 parts of chitosan oligosaccharide-butter mixture to the dough mixer, add 7 parts of water and knead into a dough, and roll it with a mold after standing for 20 minutes After molding, put it in an oven and bake at 180°C for 20 minutes, and remove the naturally cooled chitosan oligosaccharide biscuit.

Embodiment 3

[0033] After 8 parts of chitosan oligosaccharides and 3 parts of sodium stearoyl lactylate were mixed uniformly, 89 parts of butter were added and mixed uniformly, and homogenized by a homogenizer to obtain chitosan oligosaccharide-butter mixture;

[0034] Add 100 parts of low-gluten flour, 20 parts of egg liquid, 3 parts of white sugar powder, 0.5 parts of salt, 15 parts of chitosan oligosaccharide-butter mixture to the dough mixer, add 5 parts of water and knead into a dough. After standing for 30 minutes, roll it with a mold After molding, put it in an oven and bake at 200°C for 10 minutes, and remove the naturally cooled chitosan oligosaccharide biscuit.

Abstract

The invention discloses a making method and products of biscuits with stable state chitosan oligosaccharide. The making method comprises the following steps of thoroughly mixing chitosan oligosaccharide with an emulsifying agent, adding butter, performing uniform mixing, and performing homogenizing treatment to obtain chitosan oligosaccharide-butter mixture; uniformly mixing the prepared chitosanoligosaccharide-butter mixture, with flour, egg liquid, white granulated sugar powder and table slat, then adding water and flour, making dough and performing standing; and performing rolling for shaping by a mold, baking and shaping the shaped dough semi-finished products, so as to obtain the biscuits with stable state chitosan oligosaccharide. The chitosan oligosaccharide is stably and uniformlydispersed to the butter under the action of the emulsifying agent, so that carbonyl ammonia reaction between the chitosan oligosaccharide can be avoided, reaction between the chitosan oligosaccharideand other components with amino (protein) or carbonyl (reducing sugar) in biscuit ingredients can also be avoided, and the activity of the chitosan oligosaccharide can be effectively preserved.

Description

technical field [0001] The invention relates to the technical field of biscuit food, in particular to a method for preparing biscuits added with stable chitosan oligosaccharides and products thereof. Background technique [0002] As a snack food or emergency staple food, biscuits undoubtedly occupy a large part of the market share in the era of rapid economic development. With the development of science and technology and the improvement of economic strength, consumers are more fond of nutritious and healthy food, so biscuit enterprises should accelerate product upgrading and innovation according to the needs of consumers. [0003] At present, the domestic biscuit market is dominated by sandwich biscuits, cookies, snack biscuits, etc. With the emergence of a large number of joint ventures, my country's biscuit production technology level and product quality have been greatly improved, and my country's biscuit consumption will remain stable in the next few years increase.
