Background technology
In recent years, quickening along with people's rhythm of life, driven developing rapidly of the relevant food industries such as catering trade and various instant food, leisure food, and the raising along with people's living standard, the consumer is more and more higher to the requirement of food color, and these are all promoting the fast development of flavorant industry.As the saying goes: " bread is the staff of life, and food is with An Weixian ".Current people more and more pay attention to food security, and the food with natural, convenient, delicious food and multifunctional characteristics is more and more favored, back to nature, and oneself becomes the trend in epoch to seek pollution-free food.Current meat essence has been complied with this trend, develops into take natural animal-plant protein hydrolysate as raw material, produces natural meat flavor by Maillard reaction.Satisfying on the basis of people for the flavor taste requirement, also guaranteed the security of product.But the raw material that these natural materials often use is to comprise the expensive livestock and poultry meats such as chicken, duck, pork, beef, mutton, the flesh of fish, causes product price high.
As the livestock and poultry blood of abattoir by product, have suitable rich in natural resources.But the utilization for livestock and poultry blood lacks depth ﹠ wideth at present, and wastes more.Protein content is at 18~22% pig blood, and is suitable with the protein content of lean pork, pig blood account for live body heavy 5%.Equally, for other slaughtering accessory substance blood such as duck blood, protein belongs to the main chemical compositions of solid content, along with the development of meat products industry, the year amount of butchering of live pig increases severely day by day, and a large amount of blood go out of use, not only waste resource, also caused environmental pollution.
Summary of the invention
The object of the invention is to overcome above-mentioned shortcoming and provide a kind of natural, safety, meat aromatic strongly fragrant, and the preparation method of the low natural thermal response meat flavour local flavor base-material of production cost.
The preparation method of a kind of natural thermal response meat flavour local flavor base-material of the present invention comprises the following steps:
(1) preparation of hemalbumin enzymolysis product: adjusting protein quality mark is 4~8% blood, NaOH solution with 4mol/L is regulated its pH to 8.0~8.5, the pancreatin that adds the flavor protease and 1.5 of its weight 9~10 ‰~2.5 ‰, in 50~55 ℃ of lower enzymolysis 1.5~4h, 95 ℃ of enzyme 5min that go out, cooling, the centrifugal 15min of 2770 * g collects supernatant and is the hemalbumin enzymolysis product;
(2) preparation of thermal response local flavor base-material: 100 parts of hemalbumin enzymolysis products, regulate pH to 7~8 with the NaOH of 4mol/L or the HCl solution of 6mol/L, add 1~2 part of cysteine, 5~15 parts of glucose mix, fully add inherent 100 ℃~120 ℃ reaction 10~150min of reactor after dissolving, product is thermal response meat flavor base-material.
The preparation method of above-mentioned a kind of natural thermal response meat flavour local flavor base-material, wherein: blood is pig blood, duck blood.
The present invention compared with prior art, has obvious beneficial effect, as can be known from the above technical solutions: utilize blood to prepare meat essence, not only provide good utilizing approach, the reduction wasting of resources, environmental contamination reduction and improve livestock and poultry industry added value for this accessory substance, and due to its price advantage, can significantly reduce the production cost of finished product meat essence, thereby, have the marketing prospect.
The specific embodiment of the present invention is provided in detail by following examples.
