When lemon is stored for less than 3% oxygen concentration and carbon dioxide concentration is higher than 10%, it will have a bad influence on the flavor. More than 10% of carbon dioxide can increase lemon rot and reduce sourness. Less than 5% oxygen can cause lemons to taste bad. Emphasis on pre-harvest management, timely harvesting, selection of appropriate harvesting methods, timely preservation, fruit selection, grading, waxing, packaging, and storage management all extend lemon storage. In China's Sichuan Province, the harvesting of lemon is generally from late October to late November, and can be stored until the following May. Mature standards. Juice content of 28% - 30% (depending on grade) Color: dark green fruit has a long shelf life, yellow fruit must be listed immediately after picking. 2. Quality Standard. The degree and uniformity of fruit yellow, fruit size, shape, smoothness, acidity, no rot, frost damage, dry pods, no mechanical damage, no peel stains, erythema, shrinkage, variegated and so on. Second, preservation method Chemical preservation method. 1 supplies. 5% potassium permanganate solution, 5% bleach solution, combusted briquette residue or activated carbon, plastic woven bag. 2 preservative preparation. Use 5% potassium permanganate solution to soak the residue or activated charcoal of the combustion of honeycomb coal for several hours, then remove it, leach the solution, and dry it in a dark and ventilated place until it is semi-dry. Make small pieces or small particles, that is, keep fresh. Agent. 3 plastic woven bag disinfection. The plastic woven bag is cleaned and sterilized with 5% bleach, and dried in the shade. 4 bagging. Put the lemon and preservative in a plastic bag with a weight ratio of 4:1, and store the mouth in a dark place at a low temperature. The temperature is preferably 0°C-12°C. Use this method to store lemons, storage period of up to 200 days. 2. Film preservation method (fruit fresh film agent). This is a kind of coating preservative for fruits such as citrus and lemon. 1 formula. Candelilla wax 4 kg, oleic acid 1.2 kg, 0.05 kg xylene, 0.1 kg ethylene glycol, 0.2 kg sodium carbamate, 0.9 kg morpholine, 22.2 kg water. 2 preparation methods. The above materials were heated to 80°C and melted, and then added to 80°C hot water and stirred well. 3 use methods. When used, the lemon can be washed, dried, dip coated with a layer of coating agent, and then stored in an environment at 10°C to -20°C. The shelf life can be extended from 1 week to 7 weeks to 10 weeks to 20 weeks. 3. All-round fresh-keeping solution. U.S. researchers recently invented a universal antistaling solution for fruit preservation and obtained a U.S. patent. According to reports, this full-featured preservation solution is to adjust the pH of 3% citric acid or 75%--80% food grade orthophosphoric acid to 3.5 or less, add 30% to 40% sucrose, 0.3% The following sodium benzoate or ascorbic acid, 0.03% calcium hydrogen phosphate prepared. The use of the preservative solution can not only prevent the fruit from fading, inhibit the growth of bacteria, but also prevent the fruit from being shrunk and broken, keep the texture of the pulp unchanged, increase the sugar content and have a new flavor. Third, disease control Lemon physiological disease has cold damage, oil spots, pathological diseases are mainly green mold, Penicillium, black spot disease, etc. Control measures: careful harvest, reduce wounds, abrasions, scratches and other injuries; The pre-harvest bactericide or biological antagonist treatment; rapid cooling to a suitable temperature; maintain appropriate temperature and relative humidity during transport and storage, reduce ethylene accumulation; operating environment to clean.
Sunson Denim Finishing Enzyme is designed for denim finishing processing. Cellulase is regarded as a "biological pumice", which makes the indigo dye separated from denim on the washing process, and a few doses of enzyme can replace several kilograms of pumice. The less use of pumice, the smaller damage to the clothing and the smaller loss of the machine and the less sand dust in the washing environment. "Biological pumice" provides a possibility for increasing the effect of the finishing process. For example, it is possible to decolorization jeans without damaging the fabric. And the washing machine can contain less pumice and more clothing, and can also improve the production efficiency greatly.
Coenzyme N-3000 is high concentrated and neutral cellulase preparation, which is designed specially for denim abrasion process. It is only recommended for formulations that are used in bio-washing of denim garments and acts on denim garments to impart high abrasion and fading effect, which can also be used for the processing of the cotton, hemp, viscose, yarn and Lyocell.
Coenzyme NL Ultra is high concentrated and liquid neutral cellulase preparation. It is specially developed for fabric and garment biopolishing under neutral condition; it can combine with hydrogen peroxide removal in the same dye bath, and is exclusively designed for formulator.
Coenzyme NL Ultra II is new developed and high concentrated neutral cellulase preparation. It is designed for fabric and garment biopolishing under neutral condition, and specially developed for denim abrasion with high contrast and low back staining; it can combine with hydrogen peroxide removal in the same dye bath, and is exclusively designed for formulator.
Benefits:
Excellent bio-polishing effect
Clean and even fabric surface
Softer handfeel
Brighter colors
Environmental-friendly & bio-degradation
This product should be stored in a cool and dry place in sealed container, avoiding insolation, high temperature and damp. The product has been formulated for optimal stability. Extended storage or adverse conditions such as higher temperature or higher humidity may lead to a higher dosage requirement.
Enzyme preparations belong to protein, which may induce sensitization and cause anaphylaxis in sensitized individuals. Long-term exposure may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
