Abstract
A technology for preparing the dried nut including melon seeds, walnut, etc without salt crystal eduction and oxidization of oil includes such steps as providing raw materials, screening, washing, boiling for flavouring, brightening, quality guarantee treating, baking, cooling and packing.
Description
1. technical field
The invention belongs to food processing technology field.
2. background technology
Dried nuts such as melon seeds, hickory nut, Chinese torreya, pine nut are nutritious, are one of nutraceutical of the modern that chooses of U.S.'s Time.Because these dried nuts are rich in lubricant component, major part is a polyunsaturated fatty acid in its composition, autoxidation easily takes place in processing and storage become sour, and autoxidation is meant that the grease long term exposure can spontaneously carry out oxidation in air.Oxidizing process can occur on the unsaturated bond of grease, easier occurring in the free unrighted acid.Oxidation of Fat and Oils generates mixtures such as aldehyde, ketone, acid, and the character of grease and local flavor are changed.Behind the grease oxidation rancid, not only smell, flavour are bad, and essential fatty acid wherein and vitamin have reduced nutritive value because of being damaged.In addition, the catabolite after spoiled by rancid oil or fat has damaging effect to health.How preventing the oxidative rancidity of grease, is a big technical barrier of dried nut processing industry.At present, the production method of dried nut series foods such as melon seeds, hickory nut, Chinese torreya, pine nut mostly adopts following traditional handicraft to make: raw material → screening → cleaning → boiling is tasty → and frying or oven dry → cooling → packing → finished product.The product surface of making is separated out and is formed one deck bloom owing to the salt crystallization, easy dirty hand, had a strong impact on the presentation quality of product, it also is the difficult problem of the dried nut processing industry of puzzlement, in order to improve the presentation quality of product, in recent years, some Food Research Inst. have worked out new processing technology, have increased the assorted processing step that waits of polishing → cooling → sieve in conventional machining process, are about to melon seeds and pour in the sanding machine, polish after 30 minutes, add 2~3% edible salad oil, continue polishing 100 minutes then, to the melon seeds surface-brightening, then through cooling, become finished product after screening out the impurity that forms in the bruting process, the product appearance quality of making improves greatly, but because the surface has added grease, very easily produce the oxidative rancidity of grease, had a strong impact on the shelf-life of product.In order to solve the oxidative rancidity problem of grease, in salad oil, add antioxidant BHT or BHA.The adding of antioxidant had both increased production cost of products, can influence the mouthfeel and the local flavor (BHA has special smelly) of product again.In order to reduce production cost of products, reach the outward appearance of light, even some illegal businessman adds industrial chemicals such as industrial paraffin, made " malicious melon seeds ", had a strong impact on people's health.The several years ago exposure of " malicious melon seeds " has caused great social repercussion.
3. summary of the invention
The object of the present invention is to provide a kind of new production method, this production method has solved in the traditional handicraft salt crystallization simultaneously and has separated out and the easy oxidative rancidity two big technical barriers of grease, has improved the quality of product greatly, helps people's health.And technology is simple, and production cost is low, is easy to apply.
The inventor separates out the oxidative rancidity problem with grease with regard to how preventing the salt crystallization, and how to simplify technology, reduces production costs, and is easy to utilize, proposed following technical scheme:
1.. the preparation of safe, efficient, natural bright preservative: the polysaccharide material that from natural plants, extracts, be diluted to concentration and be 5% solution, through 90 ℃ of constant temperature Processing of Preparation, it is stand-by to become safe, efficient, natural bright preservative.
2.. select dried nut raw materials such as the melon seeds of full grains or hickory nut through screening, remove empty flat, rotten seed and other impurity; Drop into clean up in the clear water after, pick up drain standby.
3.. the raw material that cleans up put in the stainless-steel pan that soup spice is housed boiling 90 minutes tasty after, pull out while hot, drop into immediately and carry out light in the bright preservative and guarantee the quality and handle after 1~2 minute, with 100~130 ℃ of hot-air seasonings.
4.. be cooled to below 30 ℃, pack with laminated film bag and be finished product.
Key problem in technology of the present invention is the filming performance that utilizes bright preservative good; make it to form the diaphragm of one deck clear transparent at product surface; this diaphragm ingredient is the nutrient of needed by human body; do not influence product mouthfeel and local flavor; can stop entering of oxygen, have the grease oxidation rancid of preventing, effect is separated out in anti-salt crystallization.On probation in the processing of melon seeds and hickory nut, the product of making has surface-brightening, characteristics such as dirty hand not, has improved the quality of product, and has reduced production cost.Compare with prior art, existing product, has easy to process, work simplification (having saved polishing, cooling, sieve general labourer preface), (polishing of the prior art needs 130 minutes in the production efficiency raising, and the light in the present technique guarantee the quality only to handle need 1~2 minute), (polishing of the prior art is handled lossy in the product yield raising, and the light in the present technique guarantee the quality handle lossless, the product yield height), advantages such as product quality raising.
4. the specific embodiment
Prescription: melon seeds or hickory nut 100kg salt 12kg white granulated sugar 10kg Chinese anise 1.5kg cassia bark 0.5kg fennel seeds 0.3kg Radix Glycyrrhizae 0.5kg Chinese prickly ash 0.3kg
1.. select the melon seeds of full grains or hickory nut raw material 100kg through screening, remove empty flat, rotten seed and other impurity; Drop into clean up in the clear water after, pick up drain standby.
2.. spices such as the Chinese anise in the above-mentioned prescription, cassia bark, fennel seeds, Radix Glycyrrhizae, Chinese prickly ash are mixed, in the gauze bag of packing into, place in the pot, add clear water 50kg infusion 20 minutes, add salt, white granulated sugar then, stand-by after dissolving.
3.. the raw material that cleans up put in the pot that soup spice is housed boiling 90 minutes tasty after, pull out while hot, drop into immediately and carry out light in the bright preservative and guarantee the quality and handle after 1~2 minute, with 100~130 ℃ of hot-air seasonings.
4.. be cooled to below 30 ℃, pack with laminated film bag and be finished product.
