Embodiment 1

[0015] (1) Freeze-drying of coconut dregs: use a filter press to repeatedly press and filter the by-product coconut dregs until the water content of the coconut dregs is reduced to below 20%, then send the coconut dregs into a freeze dryer, and dry the obtained solids through crushing machine to make coarse powder with a particle size of 2-4mm;

[0016] (2) High-temperature carbonization of coconut dregs: Put the prepared coarse coconut dregs into a carbonization furnace, carbonize them at 350°C for 2 hours, and cool them down to room temperature naturally. pink;

[0017] (3) Modification of coconut dregs: add 3 g of reinforcing modifier and 100 g of water to the prepared 50 g of coconut dregs powder, mix fully, and heat up to reflux state and mix for 1 hour, press filter, add 50 g of anhydrous Ethanol, mixed evenly, heated up to reflux state and kept mixed for 30 minutes, press-filtered again, washed the filter residue three times with water, and then dried slowly in an oven...

Abstract

The invention discloses a method for preparing a function additive by using coconut residues serving as byproducts, and relates to the technical field of drink processing byproducts. The method mainly comprises the following steps: (1) carrying out freeze drying on the coconut residues, and preparing powder; (2) carbonizing the coconut residues at high temperature; (3) modifying the coconut residues. The function additive is prepared through the method; reasonable reuse of the coconut residues which are coconut juice processing byproducts is realized; the economical value of the coconut residues is increased; the prepared function additive can be used as a wear resisting agent added into a plastic product preparation raw material, so as to improve the wear resistance of a prepared plastic product to prolong the service life of the plastic product based on the wear resistance.

Description

Technical field: [0001] The invention relates to the technical field of beverage processing by-products, in particular to a method for preparing functional additives by utilizing the by-product coconut dregs. Background technique: [0002] In the field of consumption of vegetable protein beverages, coconut juice beverages are deeply loved by consumers for their unique flavor. The conventional coconut milk processing method is to wash the mature coconut and split the coconut to make the coconut water flow out. The coconut water is collected and filtered for later use, and the coconut meat is taken out to make coconut shreds, and the coconut shreds are refined and filtered to make coconut milk. , then mix coconut water and coconut milk, add syrup, salt, emulsifier, stabilizer and essence, and finally homogenize under high pressure, sterilize and fill. [0003] A large amount of coconut dregs will be produced by pressure filtration after coconut shreds are refined. If they are...
