Problems solved by technology

The dried and pickled products processed in this way all show serious browning problems, some are even black, and the color depth is uneven
Unable to form a stable and beautiful appearance impression in the minds of consumers, making it difficult to be accepted by the market, thus restricting the development of the sword bean industry
[0004] Second, the annual production cannot be achieved
However, due to the strong seasonality and short supply period of sword bean raw materials, it cannot meet the demand for sword bean raw materials for annual production

Embodiment 1

[0043] Production of light-colored dehydrated beans:

[0044] Select fresh sword beans that are fully grown but the seeds have not yet expanded, remove the parts with insect eyes and disease spots, and tear off the old tendons on both sides; use a stainless steel vegetable cutter or stainless steel knife to cut the sword beans into 2-3 mm thick Thin slices; first heat the blanching water to 95°C, then immediately put the sliced ​​sword bean slices into hot water, blanching for 1 to 2 minutes, and take them out quickly when the slices are transparent; Put the scalded sword bean slices into cooling water at room temperature to cool, rinse to 38-42°C, then take out the sword bean slices, drain the surface water, and place them in the sun to dry until white, and dry to constant weight. During the drying process, the sword bean slices should be turned frequently to make them white and dry evenly. The sun-dried sword bean slices are placed in a cool and dry environment and cooled t...

Embodiment 2

[0049] Production of light-colored dehydrated beans:

[0050] From the freshly harvested sword beans, select the fresh ones that have grown fully but the seeds have not yet expanded, remove the parts with insect eyes and disease spots, and tear off the old tendons on both sides; use a stainless steel vegetable cutter or stainless steel knife to cut the knife Cut the beans into 2-3 mm thick slices; rinse the cut beans with clean water, drain the surface moisture, and then place them in a solar drying facility (in this example, a sandwich plastic film is used as an example for illustration) Carry out blanching, the method is as follows: choose a sunny, dry, hygienic, and flat place, spread the plastic film for food packaging on the ground, spread the bean slices evenly on the plastic surface, the thickness is not more than 1 cm; then cover the food packaging Use plastic wrap. Use materials such as twigs to press slightly on the edge of the plastic; the sword bean slices are exp...

Embodiment 3

[0055] Production of light-colored dehydrated beans:

[0056] From the freshly harvested sword beans, select the fresh ones that have grown fully but the seeds have not yet expanded, remove the parts with insect eyes and disease spots, and tear off the old tendons on both sides; use a stainless steel vegetable cutter or stainless steel knife to cut the knife Cut the beans into 2-3 mm thick slices; rinse the cut beans with clean water, drain the surface water, and place them in solar drying facilities (take plastic greenhouses as an example, of course glass greenhouses or The method is as follows: In fine weather, choose a sunny, dry and hygienic, flat and open site, install a plastic greenhouse, place a sun-drying mat in the greenhouse, and spread the bean slices evenly on the sun-dried mat. Thickness does not exceed 1 cm. Then close the greenhouse. The sword bean slices are exposed to sunlight in a plastic greenhouse, and the temperature rises rapidly. When the temperature ...

Abstract

The invention discloses a processing method of light-color air-dried green string bean slices and salted products thereof. The light-color air-dried green string bean slices are prepared through the steps of: selecting fresh green string beans which grow sufficiently but of which the seeds do not expand yet and cutting into slices; blanching in hot water; rinsing; whitening under natural sunshine; and drying. The salted green string bean slices are prepared by uniformly mixing and hermetically fermenting the prepared light-color air-dried green string bean slices and auxiliary materials such as chopped fresh chili. The air-dried green string bean slices and the salted green string bean slices produced by the processing method do not become brown, are transparent and glossy and can keep good natural color; and since no chemical additives are added during processing, the safety of the foods is guaranteed, and the requirements of annual production on the raw materials can be met.

Description

technical field [0001] The invention relates to the field of food processing, in particular to a method for processing light-colored dehydrated sword bean slices and their pickled products (pickled sword bean slices). Background technique [0002] Sword bean is a characteristic vegetable widely grown in my country. After general simple cooking, the sword beans have an unacceptable peculiar smell when eaten. Therefore, the folks generally eat the sword beans after drying and pickling. After the product is marinated, it is rich in nutrition, unique in flavor, tender and crisp in texture, and has the effect of increasing appetite, so it is deeply loved by consumers. However, although this processing method has been around for a long time and the products are popular in the market, there are still many problems in food quality due to the different levels of processing technology mastered by thousands of households: [0003] First, the product has serious browning, different c...
