Description
Technical Field
The invention belongs to the technical field of plant fruit peeling, and particularly relates to an efficient peeling method for fresh pepper fruits.
Background
Peeling, cleaning and airing the fresh pepper to obtain the white pepper. However, because of the unique 'three-layer structure' (endocarp-seed film-seed) of pepper, the endocarp and the seed film are tightly bonded (the crushed seed cannot be peeled off), and the quality requirement of white pepper is that the inner film cannot be damaged, the outer skin of the pepper needs to be peeled off completely, so that the peeling of pepper is difficult without damaging the kernel of the pepper. The traditional water immersion process needs to soak fresh pepper fruits in a water area for 7-10 days, so that the pollution is large, the water quantity is difficult to keep to be updated regularly, and the peculiar smell of white pepper is easily caused; the mechanical process of peeling by using a peeling machine is easy to cause the phenomena of pepper kernel damage, kernel breaking and the like; the enzymatic peeling process relates to chemical substances, has certain environmental pollution condition, and is easy to cause peculiar smell of fresh pepper fruits when being kept stand in liquid for a long time; the biological peeling process is influenced by higher equipment investment and power consumption due to late starting, so that the popularization difficulty is higher.
The inventor also discloses a peeling method of fresh pepper fruits in the prior invention patent CN201410386933.9, which can effectively shorten the peeling period and has relatively high peeling efficiency, but the peeling process still has the condition that the peeled kernel protective film is easy to damage, so that the color of the product is poor and certain waste is caused. The inventors have further studied based on the aforementioned studies and have aimed at solving the problem that the pepper kernel protective film is easily broken.
Disclosure of Invention
The invention aims to provide an efficient peeling method for fresh pepper fruits, which aims to avoid the problem of breakage of a kernel protective film in the peeling process of the fresh pepper fruits and further shorten the peeling period. The method disclosed by the invention can be used for peeling the fresh pepper fruits quickly and efficiently, has high peeling rate and low breakage rate of kernel protective films of the fresh pepper fruits, reduces the damage to the original fragrance and taste of the pepper, and has an important application value for producing high-quality pepper in a large scale.
The above object of the present invention is achieved by the following scheme:
an efficient peeling method for fresh pepper fruits comprises the following steps:
s1, sorting: sorting the picked fresh peppers, and removing impurity leaves and large mud;
s2, rinsing and air drying: washing and air-drying the sorted fresh pepper at normal temperature;
s3, freezing: freezing the air-dried fresh pepper at the temperature of between 12 ℃ below zero and 9 ℃ below zero for 6 to 8 hours;
s4, peeling: peeling the frozen pepper directly by a fresh pepper fruit pre-breaking machine, and then separating kernels and peels to obtain pepper kernels;
s5. washing and drying: washing and drying the pepper kernels obtained in the step S4, and packaging and storing;
wherein, the sorted pepper is the same size of the whole cluster olive grains as the ripe grains, or the whole cluster has red grains or more than 2 grains yellow; the positive pressure of the fresh pepper fruit peeler is 15-30N, and the forced linear velocity is less than 10 cm/s.
According to the method, the fresh pepper fruits after sorting, rinsing and air drying are frozen under the specific low-temperature condition, and the frozen fresh pepper fruits are directly peeled by the fresh pepper fruit pre-breakage machine, so that not only can the peels of the fresh pepper fruits be well removed and the breakage of a kernel protective film be reduced, but also the frozen fresh pepper fruits can be directly peeled without a thawing process, the working procedures and the time are saved, the peeling efficiency of the fresh pepper fruits is accelerated, and the period is shortened.
After the fresh pepper fruits are frozen under the specific low-temperature condition, the water in the cells of the fresh pepper fruits is frozen, the volume of the fresh pepper fruits is increased, so that the adhesion force between the kernels and the peels is reduced, and the kernels and the peels can be effectively separated when the peels are squeezed and kneaded before unfreezing. After thawing, the adhesion between the kernels and the peels tends to recover, the phenomena of elasticity and hardness reduction of the peels are accompanied, the peels are slightly damaged, the phenomenon that peeling is not thorough due to the fact that the fruits cannot be uniformly stressed in the circumferential direction when being squeezed and kneaded is caused, the peeling rate is reduced, the breakage rate of the kernel protective film is high, and therefore the process does not need to thaw before peeling.
In order to ensure that the fresh pepper fruit pre-breakage machine can operate smoothly and efficiently, the fresh pepper fruits need to be sorted, rinsed and air-dried before being frozen. Wherein, the sorting is to separate mature fruit grains from immature fruit grains so as to prevent the immature fruit from causing incomplete peeling; the rinsing process not only ensures the cleanness and sanitation of the fresh pepper fruits, but also can prevent impurities such as small stones, silt, branches and the like from influencing the peeling efficiency and impurity content index. When the fresh pepper is too severely frozen or the peel is frostbitten, the peeling rate is greatly reduced, and the breakage rate of the kernel protective film is increased; therefore, in order to avoid over-freezing of the fresh pepper or freezing damage to the peel of the fresh pepper, the fresh pepper needs to be air-dried before freezing, so that no water, water drops or obvious water stains are generated on the surface of the fresh pepper, and the freezing temperature and time of the fresh pepper are controlled.
The invention adopts a fresh pepper fruit pre-breaking machine which is the result of earlier research of the inventor, the specific structure is shown in patent 201620311766.6, the purpose of earlier research and development of the fresh pepper fruit pre-breaking machine is mainly to pre-break the peel of the fresh pepper fruit and then carry out the next treatment, so that the effect of peeling the pepper is achieved; in the method, the fresh pepper fruit pre-breaking machine is combined with other operations, and parameters in the peeling process are adjusted and controlled, so that the peeling effect of the fresh pepper fruit can be directly achieved.
If the freezing temperature is too low or the freezing time is too long, the fresh pepper fruit peel is easy to be frozen and damaged and softened by tissue damage, the circumferential adhesive force with the kernel is not uniform any more, the probability of incomplete or incomplete peeling in the mechanical peeling process is greatly increased, and the peeling rate is seriously influenced. Meanwhile, the kernels are also easily frozen and lose original strength and hardness, so that the probability of breakage or breakage of the kernels in the mechanical peeling process is increased.
Preferably, the freezing temperature in step S3 is-12 ℃; the freezing time was 6 h. The fresh pepper fruits are frozen under the condition, so that the peel rate is optimal, and the breakage rate of kernel protection is lowest.

Example 2
In order to ensure that the fresh pepper fruits can be peeled quickly and well and ensure the high quality of the pepper, the inventor conducts a series of screens on the freezing time and the freezing temperature of the fresh pepper fruits, and the test results are shown in table 1.
TABLE 1 peeling rate of fresh pepper fruits and breakage rate of kernel protective film under different freezing temperatures and freezing times
Note: "T" represents peeling rate and "P" represents breakage rate of protective film of fruit core.
As can be seen from table 1, when the freezing temperature is too high or the freezing time is too short, the adhesion between the skin and the kernel of the fresh pepper fruit is still large and difficult to separate; therefore, the peeling rate of the fresh pepper fruits is very low; when the freezing temperature is too low or the freezing time is too long, the epidermis of the fresh pepper is too severely frozen, the peel is frozen and damaged, the tissue is damaged and softened, and the fresh pepper is not easily and completely separated from the kernel, so that the peeling rate is low, and the damage rate of the kernel protective film is high. Only when the freezing temperature is between-12 and-9 ℃ and the freezing time is between 6 and 8 hours, the high peeling rate and the low breakage rate of the kernel protective film can be simultaneously ensured, the peeling period of the fresh pepper fruits is short, the peeling of the fresh pepper fruits can be completed quickly, efficiently and in high quality, and the large-scale and commercial production of the high-quality pepper is facilitated.
