Embodiment Construction

[0018] The present invention utilizes enzymatic hydrolysis to extract hazelnut kernel oil, and the process steps of the present invention are:

[0019] 1. Preparation of Hazelnut Kernel Emulsion

[0020] Crush the peeled hazelnut kernels, soak them in water to make them fully absorb water, and then grind them with water to obtain hazelnut kernel emulsion for enzymolysis;

[0021] 2. NaOH peeling process

[0022] Soak in 3% NaOH lye for 1.5min at 80°C and peel off;

[0023] 3. Enzymatic hydrolysis of protein isolate from hazelnut kernel emulsion

[0024] The hazelnut kernel protein is first separated from the hazelnut kernel emulsion, and then the hazelnut kernel protein isolate is subjected to enzymatic extraction and oil extraction. The enzymatic hydrolysis time is 1-2 hours, the enzymatic hydrolysis temperature is 45-55°C, and the pH value is 6.5-7.5. The amount of enzyme added is 200-1500IU / g.

[0025] The enzymatic oil extraction process is to add enzymes on the basis ...

Abstract

The invention belongs to the technical field of foodstuffs, and specifically relates to an extraction technology of hazelnut oil. The invention provides a hazelnut oil extraction technology with low time consumption and high extraction rate. The technology comprises steps of a hazelnut emulsion preparing step, a NaOH peeling technology, and a hazelnut emulsion isolated protein enzymatic hydrolysis step. In the hazelnut emulsion preparing step, the peeled hazelnut kernels are crushed and soaked by using water, such that the water is fully absorbed by the hazelnut kernel particles; the hazelnut kernel particles are subject to water grinding, such that a hazelnut emulsion used in the enzymatic hydrolysis step is obtained. In the NaOH peeling technology, under a temperature of 80 DEG C, the hazelnuts are soaked for 1.5min by using a 3% NaOH alkaline solution, and the hazelnuts are peeled. In the hazelnut emulsion isolated protein enzymatic hydrolysis step, hazelnut protein is separated from the hazelnut emulsion, and the hazelnut emulsion isolated protein is subject to enzymatic hydrolysis and oil extraction, wherein an enzymatic hydrolysis time is 1-2h, an enzymatic hydrolysis temperature is 45-55 DEG C, a pH value is 6.5-7.5, and an enzyme addition amount is 200-1500IU/g.

Description

Technical field: [0001] The invention belongs to the technical field of food, and more specifically relates to an extraction process of hazelnut kernel oil. Background technique: [0002] Hazelnut, belonging to the Betaceae Corylus plant, also known as mountain chestnut, pointed grain, hammer and so on. There are about 20 species of Corylus in the world, distributed in Asia, Europe and North America; in China, there are 8 species and 2 varieties, distributed in Northeast, East, North, Northwest and Southwest regions. Hazelnut is an excellent tree species with both fruit and material. Its fruit is shaped like a chestnut, with a hard shell, fat white and round kernel, aroma, and high oil content. It tastes particularly delicious and has a long aftertaste. Therefore, it has become the most popular nut. One of the foods, it has the title of "King of Nuts", and it is also known as the four major nuts together with almonds, walnuts and cashews. [0003] Hazelnut itself is rich i...
