Description
The technical field is as follows:
the invention relates to the technical field of animal fat processing, in particular to an animal fat additive.
Background art:
the animal fat is directly extracted from animals, and due to the fact that the animal fat is rich in unsaturated fatty acid, the unsaturated fatty acid is easy to oxidize, rancidity occurs, the peroxide value is increased, the sensory properties of the fat are changed, and even the animal fat has adverse effects on organisms after being eaten.
In order to prevent oxidation of animal fat, antioxidant is usually added in the art. At present, the commonly used antioxidants are mainly classified into phenolic antioxidants and sulfur-containing antioxidants, wherein the phenolic antioxidants comprise butyl hydroxy anisole, tert-butyl hydroquinone, tocopherol and the like, the sulfur-containing antioxidants comprise thiodipropionic acid, dilauryl thiodipropionate and the like, and most of the antioxidants have certain toxicity and even have carcinogenicity on organisms. Although the edible safety of natural antioxidants is high, the natural antioxidants are expensive.
The invention content is as follows:
the technical problem to be solved by the invention is to provide the animal fat additive, which reduces the workload of ingredients by simplifying the ingredient formula and ensures the antioxidant effect and the safe eating of animal fat.
The technical problem to be solved by the invention is realized by adopting the following technical scheme:
the first object of the invention is to provide an animal fat additive, which comprises ascorbyl palmitate and natural vitamin E.
The weight percentage of the animal fat additive in the animal fat is 0.05-0.5%.
The weight ratio of the ascorbyl palmitate to the natural vitamin E is 100 (10-30).
Preferably, the weight ratio of the ascorbyl palmitate to the natural vitamin E is 100: 20.
The animal fat additive also comprises zinc citrate.
The weight ratio of the ascorbyl palmitate to the zinc citrate is 100 (0.5-5).
Preferably, the weight ratio of the ascorbyl palmitate to the zinc citrate is 100: 2.5.
The ascorbyl palmitate is prepared by esterifying palmitic acid, L-ascorbic acid and other natural components, is a high-efficiency oxygen scavenger and synergist, is a nutritional, non-toxic, high-efficiency and safe-to-use food additive evaluated by the food additive committee of the world health organization, is the only antioxidant which can be used for infant food in China, and can play the effects of antioxidation, food (grease) color protection, nutrition enhancement and the like when being used for food.
Natural vitamin E, also known as tocopherol or gestagen, is one of the most important antioxidants, is soluble in organic solvents such as fat and ethanol, is insoluble in water, is stable to heat and acid, is unstable to alkali, and is sensitive to oxygen.
The zinc citrate is an organic zinc supplement, has small irritation to stomach and high zinc content, and participates in tricarboxylic acid cycle in human body to enhance digestion and absorption functions of human body.
The addition of zinc citrate alone to animal fat does not have a significant visible antioxidant effect, but the addition of a small amount of zinc citrate to ascorbyl palmitate or natural vitamin E can further enhance the antioxidant effect of the additive.
The second purpose of the invention is to provide an animal fat additive which comprises ascorbyl citronellate and natural vitamin E.
The prepared animal fat additive can obtain better antioxidant effect by adopting the citronellyl ascorbate to replace the commonly used ascorbyl palmitate in the field at present.
The weight percentage of the animal fat additive in the animal fat is 0.05-0.5%.
The weight ratio of the ascorbyl citronellate to the natural vitamin E is 100 (5-20).
Preferably, the weight ratio of the ascorbyl citronellate to the natural vitamin E is 100: 12.
The ascorbyl citronellate is prepared by reacting ascorbic acid with (R) - (+) -citronellac acid, and the structural formula of the ascorbyl citronellate is shown as follows:
the molar ratio of the ascorbic acid to the (R) - (+) -citronellaic acid is (1.05-1.2): 1.
Preferably, the molar ratio of ascorbic acid, (R) - (+) -citronellac acid is 1.05: 1.
A method for preparing the animal fat additive comprises the following steps:
(1) adding ascorbic acid and (R) - (+) -citronellac acid into acetone, heating for dissolving, adding a catalyst, heating for reaction, monitoring the reaction process, stopping the reaction after the (R) - (+) -citronellac acid completely reacts, adding water for washing, filtering, drying a solid, recrystallizing, and drying in vacuum to obtain ascorbyl citronellate;
(2) adding natural vitamin E into the citronellyl ascorbate, and mixing completely to obtain the animal fat additive.
The catalyst is concentrated sulfuric acid or p-toluenesulfonic acid.
Since the animal fat or oil has a low freezing point, the antioxidant to be used needs to have good compatibility with the animal fat or oil in order to ensure that the antioxidant exhibits a desired antioxidant effect, and the antioxidant does not precipitate from the fat or oil but is stably and uniformly dispersed or dissolved in the fat or oil during the solidification of the animal fat or oil.
Compared with the ascorbyl palmitate which is commonly used at present in the field, the prepared ascorbyl citronellate has good compatibility with animal fat, can be dissolved in the unset animal fat, does not aggregate or even settle at the bottom of the animal fat or suspend on the surface of the animal fat in the process of solidification and storage of the animal fat, and fully exerts the antioxidation effect.
Structural characterization data for citronellyl ascorbate:1H NMR(DMSO-d6,400MHz),δ:16.76(s,1H),10.62(s,1H),5.77(s,1H),5.19(t,1H),4.80(m,2H),4.32-4.12(m,2H),2.27-1.94(m,5H),1.82(s,3H),1.72(s,3H),1.54(m,2H),0.98(d,3H)；ESI-MS:m/z＝329.36[M+1]+.
the invention has the beneficial effects that: the animal fat additive prepared by the invention has the characteristics of simple formula and strong antioxidant effect, reduces the batching workload by simplifying the component formula, and simultaneously ensures the antioxidant effect; after a proper amount of the additive is added into the animal fat, the additive can play a good antioxidation role, so that the shelf life of the animal fat is prolonged, and the edible quality of the animal fat is ensured; compared with vegetable oil and fat, the additive is more suitable for animal oil and fat, and can still exert good antioxidation after the animal oil and fat are solidified.
