Problems solved by technology

[0004] Due to the hot and humid climate of galangal during the harvest season (April-August), the traditional craft is mainly to dry in the sun, and the water drops slowly, which is prone to mildew pollution.
The traditional process only covers the surface through sulfur fumigation and oxidation, but does not achieve complete mold removal
The sulfur dioxide and sulfite brought by the sulfur fumigation process will destroy vitamin B1. Long-term use will cause gastrointestinal dysfunction, damage the liver, and endanger the human digestive system. In recent years, domestic and foreign regulations on the limit of residual sulfur dioxide have become increasingly strict. Sales of sulfur medicinal materials are becoming more and more popular
[0005] Galangal is a pungent and warm medicinal material containing volatile oil. There is no sulfur-free fresh-keeping and anti-mold technology applied to this kind of medicinal material.

Embodiment 1

[0027] Follow the steps below to prevent postharvest mildew in galangal:

[0028] Step 1: Harvest fresh galangal and cut it into sections, spray, soak or smear it with a preservative (25% of the weight of galangal) for prevention, make it even, spread out and dry until the surface of the galanga is dry.

[0029] The antistaling agent used to prevent mold pollution after the galangal is harvested consists of the following components in parts by weight: 65% of galangal stem extract treated with lactic acid bacteria; 1% of sodium hypochlorite, 0.25% of sodium benzoate, and the rest is water.

[0030] The galangal stalk extract treated with lactic acid bacteria is obtained by the following steps: Harvest fresh galangal stalks, perform water extraction at a material-to-liquid ratio of 1:5 by weight, then cool the extract, and add 10% by weight % lactic acid bacteria liquid fermentation 12h.

[0031] Step 2: Dry once (dried at 40°C) until the water content is lower than 40-50%, sli...

Embodiment 2

[0034] Follow the steps below to prevent postharvest mildew in galangal:

[0035] Step 1: Harvest fresh galangal medicinal material and cut into sections, spray, soak or smear with preservative (35% of the weight of galangal ginger) for prevention, make it even, spread out and dry until the surface of the medicinal material is dry.

[0036] The antistaling agent used to prevent mold pollution after the galangal is harvested is composed of the following components in parts by weight: 35% of the galangal stem extract treated with lactic acid bacteria; 3% of hypochlorous acid, 0.15% of sodium benzoate, and the rest is water .

[0037] The galangal stalk extract liquid treated by lactic acid bacteria is obtained through the following steps: harvest fresh galangal ginger stalks, carry out water extraction through a material-to-liquid ratio of 1:8 by weight, then cool the extract solution, and add 5% by weight % lactic acid bacteria liquid fermentation 24h.

Embodiment 3

[0041] Follow the steps below to prevent postharvest mildew in galangal:

[0042] Step 1: Harvest fresh galangal and cut it into sections, spray, soak or smear it with a preservative (40% of the weight of galangal) for prevention, make it even, spread out and dry until the surface of the galangal is dry.

[0043] The antistaling agent used to prevent mold pollution after the galangal is harvested is composed of the following components in parts by weight: 55% of galangal stem extract treated with lactic acid bacteria; 2% of sodium hypochlorite, 0.25% of sodium benzoate, and the rest is water.

[0044]The galangal stalk extract liquid treated by lactic acid bacteria is obtained through the following steps: harvest fresh galanga stalks, carry out water extraction by a weight ratio of 1:10, then cool the extract solution, and add 10% by weight % of lactic acid bacteria bacterial liquid fermentation 18h.

[0045] Step 2: Once dried (naturally dried) until the water content is low...

Abstract

The invention provides a method used for preventing galangal post-harvest mildewing. The method used for preventing galangal post-harvest mildewing comprises the following steps of cutting freshly harvested galangal into segments, carrying out treatment by using a freshness-keeping agent, and carrying out first drying; carrying out slicing, carrying out treatment by using a mould inhibitor, and carrying out second drying until the galangal slices are thoroughly dried. Post-harvest mildewing of galangal treated by the method can be inhibited to the maximum extent; moreover, the method is safe,non-toxic, convenient to use, and simple in processes.

Description

technical field [0001] The invention relates to the field of post-harvest fresh-keeping storage of agricultural products, in particular to a technology for preventing and preventing mildew of agricultural products for non-sulfurized fresh-keeping drying and mildew-proof storage. Background technique [0002] Galangal (Rhizoma Alpiniae Officinarum), also known as Galangal, Galangal, Manjiang and Bergamot Root, etc., is the rhizome of the perennial herb Galangal (Alpinia officinarum Hance) of the Zingiberaceae genus, mainly produced in Xuwen, Zhanjiang, Guangdong, etc. counties and cities. Galangal has a long history of medicinal use. It has been recorded in herbal medicines of all dynasties. It was first recorded in "Bielu of Famous Doctors" and listed as a Chinese product; it was recorded in all editions of "Chinese Pharmacopoeia", and it is one of the "Top Ten Cantonese Medicines". In Annex 1 of [2002] No. 51 "Notice on Further Standardizing the Management of Health Food R...
