Method for preparing response type peanut essence

Abstract

The invention discloses a method for preparing response type peanut essence, comprising the following steps: peanut meal is ground and the ground peanut meal is hydrolyzed by alkali protease after being screened; then the peanut meal is hydrolyzed again by protamex, and the supernate is filtered to obtain peanut meal hydrolyzate; other material is added for thermal reaction and stabilizing agent and substances for blending flavour are added after the heating is stopped, thereby obtaining the response type peanut essence. In the method, the peanut essence is produced by the thermal reaction, so that the problems of weak fragrance and poor taste of the essence with the products produced by chemical synthetic perfume are solved; in addition, as the raw material is natural, the product is harmless and nutritious with genuine and strong peanut fragrance and nutrition.

Description

technical field

[0001] The invention relates to the field of food additives, in particular to a method for preparing peanut essence by using peanut pod. Background technique

[0002] Peanut (Arachis hypogaea L.), also known as groundnut, longevity fruit, and longevity fruit, is an annual herbaceous self-pollinating plant of the leguminous Papilonaceae suborder (Papilonaceae), and has a planting history of nearly 500 years in my country. Peanuts have high medical and medicinal value and can be used to treat malnutrition, spleen and stomach disorders, various anemias, cough, phlegm and asthma, intestinal dryness and constipation, and lack of milk. "Compendium of Materia Medica Supplements" contains: Peanuts delight the spleen and stomach, moisten the lungs and resolve phlegm, nourish qi, clear the throat and relieve itching. "Southern Yunnan Materia Medica" contains: Boil peanuts in salt water to treat lung pain, stir-fry with dry fire to promote blood circulation, and treat ...

[0028] Embodiment 1, the preparation method of reactive peanut essence

[0029] (1) Add 50 g of peanut meal powder crushed to 200 mesh into a 1000 mL beaker, add 500 ml of phosphate buffer solution with pH 9.0, add 5 g of alkaline protease powder (purchased from Novozymes, alkaline protease Alcalase 2.4L), 50 Stir with an electric mixer in a water bath at 100 rpm, and after hydrolysis for 2 hours, add 5 g of complex protease (purchased from Novozymes, Protamex) and continue hydrolysis for 2 hours, then take out the beaker and heat it in a boiling water bath at 100 °C for 10 minutes to inactivate the enzyme. Filter with double-layer gauze, and the hydrolyzate is concentrated to 100mL by vacuum rotary evaporation to obtain the peanut meal hydrolyzate;
