Problems solved by technology

[0005] Second, the removal of the seed skins in the pre-treatment process of oil production will cause the loss of polyphenols, and if the seed skins are kept, the presence of polyphenols will affect the quality of the product
As dried noodles, there are certain deficiencies in nutrition: First, the protein in flour is not a high-quality protein, because it lacks an essential amino acid—lysine
Secondly, noodles lack enough vitamins and mineral elements to maintain the balance of human nerves.
Although the gluten strength of high-grade noodles increases and the mouthfeel is smooth, the reduction of vitamins and mineral elements is caused due to the high precision of flour processing (Li Weiwei, the development status of domestic health-care dried noodles [J]. Grain Processing, 2008,33 (4): 69-70)

Embodiment 1

[0045] Example 1 Preparation of whole defatted walnut powder by hydraulic cold pressing

[0046] 1. Sorting of walnut kernels: After shelling walnuts and extracting kernels, select walnut kernels without mildew and with seed coats, and remove broken walnut shells and other impurities.

[0047] 2. Hydraulic cold pressing method: put 1kg of raw materials in a hydraulic oil press with a press chamber volume of 90L, control the press chamber temperature at 30°C, and then perform the following operations: ①The pressure rises to 30Mpa and maintains for 20min, ②Then the pressure drops When the pressure reaches 0Mpa, the pressure is increased to 40Mpa and maintained for 20 minutes, and can be squeezed several times to obtain walnut meal, wherein the residual oil content is 3%. The walnut dregs are pulverized and passed through a 100-400 mesh sieve to obtain whole defatted walnut powder.

Embodiment 2

[0048] Example 2 Preparation of whole defatted walnut powder by hydraulic cold pressing

[0049] 1. Sorting of walnut kernels: After shelling walnuts and extracting kernels, select walnut kernels without mildew and with seed coats, and remove broken walnut shells and other impurities.

[0050] 2. Hydraulic cold pressing method: put 30kg of raw materials in a hydraulic oil press with a press chamber volume of 90L, control the press chamber temperature at 50°C, and then perform the following operations: ①The pressure rises to 40Mpa and maintains for 25min, ②Then the pressure drops to 0Mpa, then raise the pressure to 45Mpa, keep it for 25min, and squeeze it several times to obtain walnut meal, in which the residual oil content is 3%. The walnut dregs are pulverized and passed through a 100-400 mesh sieve to obtain whole defatted walnut powder.

Embodiment 3

[0051] Example 3 Preparation of whole defatted walnut powder by hydraulic cold pressing

[0052] 1. Sorting of walnut kernels: After shelling walnuts and extracting kernels, select walnut kernels without mildew and with seed coats, and remove broken walnut shells and other impurities.

[0053] 2. Hydraulic cold pressing method: put 50kg of raw materials in a hydraulic oil press with a press chamber volume of 90L, control the temperature of the press chamber at 60°C, and then perform the following operations: ①The pressure rises to 50Mpa and maintains for 30min, ②Then the pressure drops When the pressure reaches 0Mpa, the pressure is increased to 50Mpa and maintained for 30 minutes, and can be squeezed several times to obtain walnut meal, wherein the residual oil content is 3%. The walnut dregs are pulverized and passed through a 100-400 mesh sieve to obtain whole defatted walnut powder.

[0054] For walnut meal with a residual oil content of more than 10% after hydraulic cold...

Abstract

The invention provides walnut noodles and a preparing method thereof. Walnut kernels with skin are used as the raw material, degreased walnut powder with residual oil amount below 3% is prepared with the hydraulic cold pressing method or through combination of the hydraulic cold pressing method and the supercritical CO2 extraction method, the degreased walnut powder is mixed with flour according to the weight ratio of (1-30):100, then saline water and flour are added to the mixture, and proofing and pressing are conducted to obtain noodles, namely the walnut noodles. Polyphenol in walnut kernel skin is maintained in walnut meal, degreased walnut powder with low oil content is obtained through innovation of the oil extraction technique, the degreased walnut powder is mixed with flour according to a certain proportion, and auxiliaries are added in proper proportion to develop the walnut noodles rich in walnut nutrients. The walnut noodles have distinct characteristics in terms of nutritive characteristics, texture features and organoleptic quality, walnut nutrients can be better used for promoting health, walnut meal is utilized, and the technical problem that walnut polyphenol affects product quality is solved.

Description

technical field [0001] The invention relates to the field of food engineering, in particular to walnut noodles and a preparation method thereof. Background technique [0002] Walnut is one of the five major woody grain and oil tree species supported by the state. The by-product of walnut oil production --- walnut meal is rich in high-quality protein, crude fiber, trace elements and minerals, and is also a good food processing auxiliary material. Reuse of walnut pulp can increase the added value of walnut processing and make full use of walnut nutrition. It is of great significance to ease the market price of walnut oil and promote the sustainable development of walnut industry. [0003] At present, the following problems still exist in the reuse of walnut meal: [0004] First, the residual oil content of walnut meal is too high. Among the many walnut oil production methods, the oil production methods that can prevent the protein in walnut meal from heat denaturation are ma...
