The manufacture method of non-hydrogenated margarine
The present invention relates to prepare the method for margarine-a kind of edible oil and fat, belong to the production and processing technical field of edible oil or fat with oleum sapii (being commonly called as skin oil).
Margarine, claim margarine, margarine again, be a kind of be the edible oil and fat of main component with the hydrogenation refinery vegetable oil.Margarine from 1869 in France, after Britain is born and patents, worldwide obtained development rapidly.The primary raw material of producing margarine oil's wet goods edible oil and fat is an animal and vegetable oil, wherein mainly is vegetable oil, as soybean oil, rapeseed oil, sunflower oil, peanut oil, cottonseed oil, palm oil and coconut wet goods.Also have and utilize animal oil to do raw material, as utilizing tallow to be the matrix grease in the United States Patent (USP) (U.S.Patent 3,944,585, and March 16,1976).Up to now, being used as the matrix grease-tristearin of margarine both at home and abroad, all is the hydrogenation tristearin that adopts hydrogenation technology to make.Because can produce trans-fatty acid in the hydrogenation process, as antiform oleic acid and trans-linoleic acid etc., content can reach 20-40% in margarine, also can produce a certain amount of conjugate acid simultaneously and be present in the product of hydrogenated fat.Because trans-fatty acid is compared with natural cis fatty acid, the difference aspect biochemistry constantly is being found understanding, and its influence to human body is subjected to people's attention day by day.
The manufacture method that the purpose of this invention is to provide a kind of non-hydrogenated margarine.
Non-hydrogenated margarine adopts non-hydrogenated shortening oil to process as compound lard.The matrix grease of this compound lard adopts all refining oleum sapiis (skin oil) or adopts 40~10%(weight ratio) refining oleum sapii (skin oil) and 10~40%(weight ratio) non-hydrogen helping digestion tallow such as lard, tallow.Again matrix grease and other refining vegetable oils were formed the compound lard of making non-hydrogenated margarine by weight 1: 1 to 5: 1.
The manufacture method of non-hydrogenated margarine is after the compound lard heating fusion, add EC-10 emulsifying agent 0.2~0.5%, make it to dissolve fully, carry out an emulsification, after 30~50 minutes, the water of adding 15~18%, after carrying out high speed second emulsifying and uperization, lower the temperature rapidly and carry out low temperature and knead, remain on then under 20 ° ± 5 ℃ temperature and stir fast, the slaking 24 hours under 5 ° of-10 ℃ of temperature conditions of perfusion finished product is packaged into the non-hydrogenated margarine product again behind the blowing after check.
Food additives EC-10 emulsifying agent is a kind of nonionic surface active agent, is provided by the East China Normal University chemical plant.
The quality index of non-hydrogenated margarine of the present invention meets following national standard [GB 5524-5539-85], [GB 2707-2763-81] fully:

Non-hydrogenated margarine of the present invention all is being similar to or is being similar to cream aspect aesthetic appearance, nutritive value, taste and the plasticity, it contains abundant unrighted acid, and does not contain cholesterol or cholesterol level is very low, is a kind of desirable edible oil and fat.
Embodiment 1:
Will be by the 80%(weight ratio) the refining oleum sapii and 20% refining soya-bean oil form compound lard, EC-10 emulsifying agent 0.5% is added in heating fusion back, after making it to fuse fully, carry out an emulsification, after 30~50 minutes, add 18% water again, carry out high speed second emulsifying and uperization, cooling is kneaded rapidly then, and remain under 20 ° ± 5 ℃ temperature conditions fast and stir, non-hydrogenated margarine is promptly made in finished product slaking 24 hours under 5 ° of-10 ℃ of temperature conditions.See Table 1.
Embodiment 2:
Will be by the 75%(weight ratio) the refining oleum sapii and 25% refining rape oil be combined into compound lard, after the heating for dissolving, add EC-10 emulsifying agent 0.2%, after making it to dissolve fully, carry out an emulsification, the water of adding 15% carries out high speed second emulsifying and uperization after 30~50 minutes, cooling is kneaded rapidly again, remain under 20 ° ± 5 ℃ temperature conditions fast and stir, non-hydrogenated margarine is promptly made in finished product slaking 24 hours under 5 ° of-10 ℃ of temperature conditions.See Table 1.
Embodiment 3:
With the 70%(weight ratio) the refining oleum sapii and 30% refining tea oil be combined into compound lard, after the heating for dissolving, add EC-10 emulsifying agent 0.3%, after making it to dissolve fully, carry out an emulsification, after 30~50 minutes, add 15% water again and carry out high speed second emulsifying and uperization, cooling is kneaded rapidly then, remain under 20 ° ± 5 ℃ temperature conditions fast again and stir, non-hydrogenated margarine is promptly made in finished product slaking 24 hours under 5 ° of-10 ℃ of temperature conditions.See Table 1.
Embodiment 4:
With the refining soya-bean oil that respectively is 40% refining oleum sapii and non-hydrogenated lard and 20%, form compound lard, EC-10 emulsifying agent 0.4% is added in heating fusion back, after making it to fuse fully, carry out an emulsification, the water of adding 15% carries out high speed second emulsifying and uperization after 30~50 minutes, cooling is kneaded rapidly again, and remain under 20 ° ± 5 ℃ temperature conditions fast and stir, non-hydrogenated margarine is promptly made in finished product slaking 24 hours under 5 ° of-10 ℃ of temperature conditions.See Table 1.
