Description

High-lipid minced fillet and preparation method thereof
Technical Field
The invention belongs to the field of food processing, and particularly relates to high-lipid minced fillet and a preparation method thereof.
Background
Oleogels are polymeric gel-like materials formed by encapsulating a liquid oil within crystalline particles or having a three-dimensional network structure. The preparation methods of oleogel can be roughly divided into two types: direct and indirect processes. The use of direct process prepared oleogels in the food industry is challenging due to the presence of undesirable waxy aroma and high melting temperatures. Therefore, indirect methods involving the formation of three-dimensional polymer network structures using hydrocolloids such as proteins and polysaccharides as gelators are receiving increasing attention.
Currently, several patent documents record the aspects of oleogels prepared from single proteins/polysaccharides or complexes of both. For example, chinese patent No. CN116420868A discloses a method for preparing a vegetable-based fat substitute rich in dietary fibers, which comprises compounding soluble dietary fibers in okara with soy protein in different proportions, and thermally inducing to form a soy protein oil gel fat substitute rich in fibers. The process has a fat-like taste, but the process for extracting the fiber and the protein is complicated, and the oxidation of the grease can be accelerated by long-time high temperature in the heat induction process, so that the nutritive value of the oleogel is reduced. The invention discloses a preparation method and application of a composite double-network zero-trans low-saturated fatty acid oil gel, wherein the preparation method comprises the steps of taking water-soluble polysaccharide as a construction raw material of a biopolymer network, preparing the water-soluble polysaccharide into water foam, removing water from the water foam to obtain porous aerogel, then using the porous aerogel for absorbing heated oil-soluble micromolecules or grease, and cooling and homogenizing the aerogel after oil absorption to obtain the composite double-network zero-trans low-saturated fatty acid oil gel. The foaming requirement of the invention on polysaccharide is higher, the nutritive value of the oleogel is reduced by heating the oil in the preparation process, and the high-concentration glyceryl monostearate is difficult to be accepted by consumers.
Minced fillet is a common food, and a large amount of grease is often required to be added due to processing and taste requirements. The addition of the oil gel instead of the grease can make the surimi product healthier, and no surimi preparation process using the oil gel instead of the grease has been reported at present.

As used herein, the terms "comprising," "including," "having," "containing," and the like are intended to be inclusive and mean an inclusion, but not limited to.
Example 1:
the defatted coconut flour-based oil gel is used as a substitute of vegetable oil to be added into the minced fillet product, the preparation process of the minced fillet product is controlled, and the minced fillet product has consistent size. The effect of the minced fillet without adding grease and the minced fillet with directly adding vegetable oil are compared as a control group.
1.1 preparation method of surimi: firstly, thawing commercial chub meat emulsion at a low temperature, taking 100g of meat emulsion after thawing, chopping for 1min by a household meat grinder, then adding 2g of edible salt, continuously chopping for 2min, then adding sample oil gel, and chopping for 3min. And then the pasty meat paste is subjected to sausage filling and sealing. And finally, carrying out two-stage heating (40 ℃,30min,90 ℃ and 60 min) on the product, and rapidly cooling the product to room temperature in ice water after the heating is finished, and preserving the product in a refrigerator for refrigeration.
1.2 texture and gel Property test method of minced fillet product
The texture and gel strength of surimi were measured by the P/0.5 and P/0.5S probes of the texture analyzer. The probe was pressed vertically against the top of the surimi gel at a speed of 1 mm/s. The test parameters were as follows: the sample height was 20mm, the trigger force was 0.2N and the strain was 60%. The hardness, cohesion, tack, elasticity, chewiness and gel strength of the gel were analyzed and calculated by texture analysis software (v 1.18) program. The test results are shown in Table 1:
TABLE 1 texture and gel Strength of surimi products prepared with corn oil and oleogel
As can be seen from table 1, the addition of liquid corn oil reduced the texture and gel strength of the surimi product, while the addition of oleogel had less disruption to the texture and gel strength of the surimi product.
1.3 Water holding Capacity test method of minced fillet product
The water holding capacity of the surimi product was determined by centrifugation. Cutting minced fillet into 5mm×5mm small pieces, weighing mass M 1 (about 3 g) gel, wrapping with two layers of filter paper, loading into a centrifuge tube, centrifuging at 10000r/min for 10min, taking out gel, and weighing to obtain gel with mass M after centrifugation 2 . The gel water retention was calculated as follows:
the test results are shown in FIG. 1. As can be seen from the figure, the water holding capacity of the surimi decreases upon addition of liquid corn oil. And the loss of water in the minced fillet is less due to the addition of the oil gel, which shows that the damage degree of the oil gel to the internal result of the minced fillet is lower.
1.4 method for testing moisture distribution of minced fillet products
And testing the moisture distribution and composition of the minced fillet product by using a low-field nuclear magnetic resonance apparatus. The transverse relaxation time T2 of the gel was determined using a Carr-Purcell-Meiboom-Gill (CPMG) pulse sequence. The measurement parameters were set as follows: sw=200khz, rg1=20, p1=18.00s, drg1=3, td=3999550, prg=2, tw=2500 ms, ns=8, p2=37.00s, te=0.250, nech=8000. Each sample was repeated 3 times.
The proton density profile of the surimi was then determined by nuclear magnetic resonance imaging software. Parameter setting: tr=500 ms, te=18.2 ms. The test results are shown in FIG. 2.
The results in fig. 2A show that the direct addition of corn oil resulted in a decrease in the non-flowing water area fraction and an increase in the free water area fraction in the surimi gel as compared to surimi prepared without the addition of grease, indicating that the direct addition of corn oil resulted in a significant loss of non-flowing water in the surimi gel. In contrast, the addition of oleogel has less effect on the no-flow water in the surimi gel. The results of FIG. 2B further demonstrate the results of low field nuclear magnetic resonance and water holding capacity.
Based on the results, the oleogel provided by the invention can be used as an effective substitute for plant-based fat, and has application prospects in the field of food processing.
EXAMPLE 2 preparation of defatted coconut flour-based gel
The defatted coconut flour was precisely weighed, 20ml of a defatted coconut flour solution with a mass fraction of 2.5% was prepared, 20ml of corn oil was added, and homogenized and emulsified for 2min using a high-speed homogenizer at 7000 rpm. The emulsified emulsion was poured into a petri dish, frozen at-20 ℃ for 24 hours, and then vacuum freeze-dried at-60 ℃ for 48 hours. Finally, the lyophilized sample was sheared for 2min at 500rpm using a homogenizer to obtain an oleogel.
The above embodiments are only illustrative of the preferred embodiments of the present invention and are not intended to limit the scope of the present invention, and various modifications and improvements made by those skilled in the art to the technical solutions of the present invention should fall within the protection scope defined by the claims of the present invention without departing from the design spirit of the present invention.
