## Abstract

The present disclosure relates to olive pomace and a green methodology to obtain derivative products for it valorization. The obtained products may be used as a solid substrate, nutraceuticals, cosmetics or food supplements.

## Claims

### Claim 1

An olive pomace or an olive pomace solid substrate, comprising:
up to 1% (m/m) of olive fat material; and
up to 0.06% (m/m) of phytotoxic compounds.

### Claim 2 (depends on 1)

The olive pomace or olive pomace solid substrate of claim 1, comprising up to 0.5% (m/m) of the olive fat material.

### Claim 3 (depends on 1)

The olive pomace or olive pomace solid substrate of claim 1, comprising up to 0.02% (m/m) of the phytotoxic compounds.

### Claim 4 (depends on 1)

The olive pomace or olive pomace solid substrate of claim 1, wherein the phytotoxic compounds are phenolic compounds.

### Claim 5 (depends on 1)

The olive pomace or olive pomace solid substrate of claim 1, wherein the phenolic compound is selected from the group consisting of: aglyconic and glycosidic forms in particular, hydroxytyrosol, tyrosol, oleuropein, verbascoside, elenolic acid, catechol, rutin and mixtures thereof.

### Claim 6 (depends on 1)

An africultural additive, comprising the olive pomace or olive pomace solid substrate of claim 1.

### Claim 7 (depends on 6)

The agricultural additive of claim 6, wherein the agricultural additive has a germination index of at least 85%.

### Claim 8 (depends on 6)

The agricultural additive of claim 6, wherein the agricultural additive has a pH of 4.8-5.8.

### Claim 9 (depends on 8)

The agricultural additive of claim 8, wherein the agricultural additive has a pH of 5.1-5.8.

### Claim 10 (depends on 6)

The agricultural additive of claim 6, wherein the agricultural additive comprises at most 170 mg gallic acid equivalents/100 g of wet weight of olive pomace.

### Claim 11 (depends on 10)

The agricultural additive of claim 10, wherein the agricultural additive comprises 20-60 mg gallic acid equivalents/100 g of wet weight of olive pomace.

### Claim 12 (depends on 6)

The agricultural additive of claim 6, wherein the agricultural additive is a soil fertilizer, a soil substrate additive, an agricultural irrigation additive, or a soilless culture additive.

### Claim 13 (depends on 1)

A method for obtaining an olive pomace solid substrate of claim 1 and an extract, comprising:
extracting of an olive fat from an olive pomace;
adding water to the olive pomace in a 1:15-1:80 mass of olive pomace: volume of water ratio to form a first solution;
stirring the first solution at 600 rpm for 10-90 minutes until a temperature of 40±5° C. is reached;
stirring the first solution at 600 rpm for 10-90 minutes after the temperature of 40±5° C. is reached;
filtrating the stirred first solution to collect an olive pomace solid phase and an olive pomace aqueous extract;
adding water to the collected olive pomace solid phase in a 1:15-1:80 mass of olive pomace solid phase:volume of water ratio to forma second solution;
stirring the second solution at 600 rpm for 10-90 minutes, until a temperature of the 40° C.±5° C.;
stirring the second solution at 600 rpm for 10-90 minutes, after the temperature of the 40±5° C. is reached;
filtrating the stirred second solution to collect a final olive pomace solid phase and a final olive pomace aqueous extract;
collecting the final olive pomace solid phase and the final olive pomace aqueous extract.

### Claim 14 (depends on 13)

The method of claim 13, wherein the step of adding water to the olive pomace or to the pomace solid phase is performed in a ratio of 1:40-1:50.

### Claim 15 (depends on 13)

The method of claim 13, further comprising: drying the final olive pomace solid phase for 60 minutes at 60° C. until 5% (m/m) moisture is reached.

### Claim 16 (depends on 13)

The method of claim 13 wherein the steps of adding water, stirring, filtrating and collecting and drying are repeated using olive pomace.
