The disclosure relates to a high-bioactivity black dry apple chip and a processing technology thereof. The processing process is as follows: fresh fruits.fwdarw.sorting.fwdarw.peeling.fwdarw.slicing.fwdarw.fermenting.fwdarw.drying.fwdarw.packaging.fwdarw.black dry apple chips. According to the disclosure, a high-temperature Bacillus subtilis fermentation broth atomization spray technology is adopted to atomize the processed apple slices under the condition of 60° C.-80° C., the cut apple slices are irradiated with 60 Coy rays at a dose of 4 kGy to promote carbonyl ammonia reaction so as to make apple slices generate burnt black. According to the disclosure, Bacillus subtilis antimicrobial peptide solution is sprayed so as to utilize its bacteriostatic function to avoid pathogen infection during shelf life.

The disclosure provides chips formed by slicing with an apple cell clean water jet scalpel and a processing technology. The processing technology comprises the following specific steps: harvesting fresh fruits, sorting, peeling, slicing, drying and packaging to obtain the apple crispy chip. According to the disclosure, the tangxin apple is peeled by adopting an ultrahigh pressure water jet flow cutting technology, cut into slices with a thickness of 5 mm and inoculated for 15 min in 30° C. and 30% Lactobacillus brevis fermentation broth. PPO is a terminal oxidase with Cu.sup.2+ as a prosthetic group, and Lactobacillus brevis and Lactobacillus plantarum are complexed with Cu.sup.2+, leading to rapid oxygen consumption to generate organic acid and CO.sub.2, quickly reduction of pH and creation of an approximate oxygen-free environment to effectively inhibit PPO activity while removing oxygen required in enzymatic browning, thereby effectively inhibiting browning.

A method is provided for improving drying efficiency for producing a dried edible plant composition while keeping a characteristic and fresh flavor and color tone inherently possessed by a food product using an edible plant without requiring special equipment or conditions, and a dried edible plant composition having improved quality obtained by this method. A method is provided for producing a dried edible plant composition that contains a non-edible part of an edible plant, in a dried state, in an amount of 3% by mass or more and 70% by mass or less based on the total mass of an edible part and the non-edible part. The method includes crushing and mixing the edible part and the non-edible part, and drying until a moisture content reaches 20% by mass or less by forced-air drying at a temperature of 20° C. or more and 80° C. or less.

The present invention includes a method and food product made by at least partially enclosing a food product with a water-permeable membrane; and contacting a brine or sugar solution with a water activity sufficiently high to draw water molecules across the water-permeable membrane and away from the food product to preserve the food.

Apparatus and related methods for adding increased functionality to a food dehydrator through the use of stackable drying trays that define a circulation plenum during operation and then nest within one another during disassembly so as to reduce an overall storage size of the food dehydrator. The food dehydrator can further include a base portion having a removable splash guard to prevent the introduction of liquids or solids into a mechanical space within the base portion.

Disclosed is an antioxidative method for cold dehydration and packaging of fruit and vegetable products, including: reception and verification of their biological certification; manual or automatic washing with drinking water; manual or automatic peeling; cutting, by hand or by special automatic machines; cooking in the oven with dehumidifier and gas burner, at a temperature between 25 C. and 40 C., for 24/48 hours; during cooking, the dehumidified air is discharged from the first end and suctioned wet by the second end and vice versa with alternating steps of 15 minutes; packing, immediately after the dehydration, by way of common machines suitable for packaging a predetermined amount of fruit and vegetable products in sealed opaque bags filled with nitrogen for food use; and storage in dark, fresh and dry warehouses.
