Abstract

The invention discloses a globulin extraction method based on nuclear magnetic resonance detection. The method comprises the following steps: weighing 15-20g of alkaline protease, adding into 400-500mL of phosphoric acid buffer solution, putting into an ultrasonic oscillator, ultrasonically oscillating at the power of 100-200W for 30-33min, centrifuging the reaction solution by using a horizontalcentrifuge at the rotating speed of 6000-7000r / min for 25-30min, and separating to remove supernatant to obtain immobilized protease for later use; weighing 600-700 g of walnut kernels and putting into warm water at 60-70 DEG C to be soaked for 1-2 h, putting the walnut kernels into a pulverizer to be fully pulverized, putting the walnut kernels into a reaction tank after being pulverized, addinginto a centrifugal machine to be subjected to centrifugal treatment, centrifuging the mixed solution A for 30-40 min under the condition of 3000-4000 r / min, and collecting a supernatant A.

Description

Technical field[0001]The present invention relates to the field of walnut protein peptide processing, and more particularly to a globulin extraction method based on nuclear magnetic resonance detection.Background technique[0002]Walnuts, also known as walnuts, porridge, is a walnut plant. With a flat peach, cashews, hazelnuts and called the world famous "four dried fruits". Walnuts contain rich nutrients, 15 to 20 grams per bicker, more fat, 10 grams of carbohydrate, and contain a variety of trace elements and minerals such as calcium, phosphorus, iron, and carotene, nuclear Variety of vitamins such as lumens. It is beneficial to the human body. It is one of the nut foods that are popular with the people. Walnuts are hard and need to be worried. Walnuts contains a globulin, while the existing walnuts extracts the process complex, high cost, and cannot perform nuclear magnetic resonance detection of extracted globulins. In this respect, the present invention proposes a nuclear magneti...
