Composite konjak paste and its preparing method
Technical Field
The invention relates to the technical field of konjak composite paste foods, in particular to a composite konjak paste and a manufacturing method thereof.
Background
The compound konjak paste is a novel food which is compounded with nutrient materials such as buckwheat flour and the like into paste by utilizing the gelling effect of the konjak gum and the carrageenan. The biscuits on the market are extremely hard and have large irritation to the stomach, the electuary foods are extremely inconvenient to eat, and the paste foods adapt to the fast-paced life style of modern people, are convenient to carry and timely in bag opening and are more easily accepted by people. The high dietary fiber of konjac gum can accelerate gastrointestinal peristalsis to shorten defecation period, and the high dietary fiber can wrap carbohydrate in the konjac gum to buffer the rise of blood sugar. The Konjac Glucomannan (KGM) in the konjac glucomannan is absorbed by water and swells and is associated with intermolecular hydrogen bonds to be separated from water solubility, and the konjac paste utilizes the characteristic of the konjac glucomannan to contain additional materials into intermolecular gaps in the process of association of the konjac glucomannan and the carrageenan to form the konjac paste with nutritional value. The konjak paste product is rich in various amino acids and vitamins due to the addition of rich food materials, for example, Chinese patent ZL2016103721379 discloses a chia seed konjak paste, every 1000g of the konjak paste product contains 0.3-200g of chia seeds serving as food raw materials, 0.1-8 g of konjak glue powder, 0.3-3g of xanthan gum, 0.1-6g of carrageenan powder, O-200g of white granulated sugar and O-20g of honey, water is added for blending and stirring uniformly, the mixture is heated to 85-90 ℃ and then filled, and then the mixture is sterilized at 121 ℃ to prepare paste or thin paste-like food. However, the chia seed konjak paste has a single taste and only has sweet taste of sugar and honey; if the product is used as a meal replacement food, the product needs a large amount of food for maintaining the nutritional ingredients required by the body every day, and is lack of the ingestion of protein, dietary fiber and fat required every day, so that the nutrition is incomplete; the konjac gum powder, xanthan gum and carrageenan powder are not easy to digest and absorb when the practical amount is too large.

And (3) adding the foamed tremella into the step (2), cutting into pieces, and juicing. Buckwheat flour can form a dough with a fixed shape after being heated, boiled and cooled in a pot, so that the buckwheat flour is considered as a large-proportion formula of a finished product of the konjak paste, but the buckwheat flour has a stiff and unpleasant taste, and the tremella is high in brittleness after being dried and soaked and is used as pulp to increase the novelty feeling during chewing to bring pleasant enjoyment of the taste, so that the tremella is added to improve the taste of the buckwheat flour, more elastic taste is brought to the finished product of the konjak paste, and meanwhile, the tremella is also a healthy food rich in various amino acids.
In the step (2), the Chinese dates are firstly put into water with the temperature of 100 ℃ for blanching for 2-3 min and then are chopped and juiced. The unique jujube flavor of the Chinese dates can be further covered to the maximum extent, so that the taste of the finished product of the konjak paste is more acceptable to the public.
And (3) placing the red Chinese wolfberry and the hawthorn in the step (2) into a container, and adding a proper amount of water to foam for 30 min. The lycium ruthenicum and the hawthorn are hard, if the lycium ruthenicum and the hawthorn are not soaked in water, particulate matters still exist during juicing, and the lycium ruthenicum and the hawthorn can be soaked in the water to be soft, so that the substances with obvious granular feeling are prevented from entering a final finished product.
And (2) boiling the coix seeds in the step (1) in boiling water for 10-20 min. After the pearl barley is boiled in boiling water for a period of time, the mouthfeel is more mellow, and the overall mouthfeel of the konjak paste is improved.
The total water added in the steps (2) and (3) is 150-300% of the total mass of the actinidia kolomikta, dried tremella, red dates, medlar, perilla seed oil, purple sweet potato powder, buckwheat flour, pearl barley, soybean flour, dried hawthorn, egg white, konjac glucomannan and carrageenan, the water in the step (2) accounts for 30% of the total water, and the water in the step (3) accounts for 70% of the total water. The water amount for squeezing and boiling is reasonably distributed to form the konjak paste product with optimal elasticity, hardness and taste.

And (4) analyzing results:
the finished product of the konjak paste obtained in the embodiment 3 of the invention is purplish red in color, the sliced konjak paste sample is firm and not easy to deform, has fine pulp, uniform fruit grains and no particles with naked eyes; the sour and sweet are blended, and the boiled fragrance of the actinidia kolomikta, the Chinese date and the five cereals is achieved; sticky and glutinous taste, chewy, slight elasticity and no sand feeling.
The konjac paste finished products of the examples 1 and 2 are light purple, and compared with the konjac paste finished products of the examples 3, the konjac paste finished products of the examples 1 and 2 have a large added moisture content, and although the samples are firm and not easy to deform after being cut into pieces and basically meet the standard, the elasticity of the samples is insufficient, the elasticity of the konjac paste finished products of the examples 2 is obviously insufficient, the resilience of the TPA test is only 0.15, and the konjac paste finished products only have the stiff feeling of the buckwheat products. The water content of comparative example 4 is 400%, at this time, the konjac paste is in a light purple semi-rigid state, the rigidity of the konjac paste is obviously insufficient due to a large amount of water, the taste and the smell of the konjac paste are light at this time, the mouth feel is not elastic, the resilience of the konjac paste is only 0.03 in a TPA test, and the konjac paste has an obviously single mouth feel after lacking sour taste, only has sweet taste and is slightly poor in mouth feel without adding actinidia arguta. Comparative example 1 had too little water content and was deep purple, large pieces of powdery particles in the konjac paste were not completely melted, resulting in a remarkable granular sensation, a large number of particles were visible with the naked eye, a strong sandy sensation was felt when chewing, the five-cereal flavor was light, the TPA test hardness was 405 gf, and the mouth feel was hard. It can be seen that the konjak paste product has the best color, forming degree, taste, smell and mouthfeel when the mass of water accounts for 150% of the mass of dry matter.
In comparative examples 2 and 5, compared with example 3, a small amount of particles were visually observed, a slight sandy feeling was observed when the food was chewed, and it was found that powdery particles were easily generated when the powder was directly added to the pan or the food was added to the juicer at one time after the powder was added, which is positively avoided in the present invention, and the TPA test hardness was 301 gf, and the mouth feel was hard. The flour materials such as purple sweet potato flour, soybean flour and buckwheat flour are easily wrapped by water after being added into water, thereby forming powdery particles, which causes unpleasant sandy mouthfeel, and therefore, the stirring speed needs to be increased to avoid the formation of powdery particles. According to the invention, 6g of perilla seed oil is added before the powdery substance is added to form a water-oil mixing system, so that powdery particles are not easy to generate in the powdery substance, the powdery substance is added for three times, the speed of the particles formed in the system is relieved, the substances added into a juicer from a small amount to a large amount after each addition are used for diluting the mixing system, the product of the powdery particle substance is controlled, and finally, a konjak paste finished product with the particles as few as possible can be obtained, and the mouth feel of the sand is reduced.
Compared with the example 3, the comparison example 3 does not add the pearl barley, and experiments show that the juicing mixture obtained by adding water to the medlar, the jujube, the hawthorn and the tremella is easy to precipitate in a short time, when the juicing mixture is added in subsequent times, the condition that the first times of toppings are supernatant and the last times of toppings are bottom precipitated substances occurs, and the final addition of the precipitates can cause the granular feeling when the stirring and mixing time is short, so the stirring and mixing time must be increased by times, so the medlar, the jujube, the hawthorn and the tremella are juiced together with the pearl barley after being cut up, the juice can be more silky, the mixing is more uniform and is not easy to precipitate, the required parts can be conveniently obtained when the konjak paste is added into a pot in the subsequent steps, each part of the juicing mixture is uniform, the granules can be obviously eliminated, the stirring time in the last step is shortened, and the mouth feel of the obtained konjak paste is, the soft and fine taste of the finished konjak paste is improved.
Compared with the embodiment 3, the elasticity of the konjak paste product is obviously insufficient without adding the tremella, the resilience tested by TPA is only 0.12, as the buckwheat flour can form a dough with a fixed shape after being heated, boiled and cooled in a pot, the dough has stiff and unpleasant mouthfeel, and the tremella has higher crispness after being dried and soaked, and can be used as pulp to increase the enjoyment of mouthfeel brought by the novel feeling during chewing, therefore, the tremella is added to improve the mouthfeel of the buckwheat flour, bring more elastic mouthfeel to the konjak paste finished product, and is also a healthy food rich in various amino acids.
According to the component proportion of the embodiment 3, the energy contained in each 100 g of the konjak paste is calculated by inquiring the data of the national food nutrient composition table, and assuming that 150g of konjak paste is eaten by three meals a day, the total energy ingested by the konjak paste every day is 1297.7505 kcal, the total protein ingested by the konjak paste every day is 46.304g, the total fat amount is 29.602g, the total carbohydrate amount is 201.388g, the dietary fiber amount is 29.602g, the protein amount is 14.0%, the fat amount is 25.4%, the carbohydrate amount is 60.7%, and the konjak paste basically reaches the standard and can be eaten every day.
The foregoing description is illustrative of the present invention and is not to be construed as limiting thereof, as the invention may be modified in any manner without departing from the spirit thereof.
