Yes, its safety has been approved by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA). as well as Joint FAO/WHO Expert Committee on Food Additives (JECFA).

FDA

Sodium benzoate is generally recognized as safe (GRAS) and can be used as an antimicrobial agent and flavoring agent in food with the maximum usage of 0.1% (9). It is also GRAS when used as a preservative in feed. (10)

EFSA
Sodium benzoate (E211) is listed in Commission Regulation (EU) No 231/2012 as an authorised food additive and categorized in “Additives other than colours and sweeteners” (11).

Safety re-evaluation in 2016
Base on the studies of genotoxicity, carcinogenicity, reproductive toxicity and other researches, EFSA considered that the use of sodium benzoate does not raise a health concern and derived an acceptable daily intake (ADI) of 5 mg/kg bw per day (expressed as benzoic acid) in 2016. (12)

Approved uses
In Food

It can be found in a lot of food labels with its name or E211. The approved food uses are listed in the same categories with benzoic acid, sodium and calcium benzoate (E210-E213) with the maximum used levels range from 150 to 6,000 mg/kg. It can also be combined with sorbic acid-sorbates (E 200–202) and p-hydroxybenzoates (E 214–219). (13)

Silage Additive

EFSA concluded that sodium benzoate was safe for the consumer when used as a silage additive in pigs, poultry, bovines, ovines, goats, rabbits and horses. Meanwhile, it reduces pH and increases the preservation of dry matter and therefore improve silage production. (14)

Titanium Dioxide PA101 is high quality Anatase Grade Titanium Dioxide used in Paints, Plastics, Textiles, Soap etc. The PA101 is equivalent to grades TTK Anatase ISI and many other standard grades for Anatase.

P A101 is an Anatase Titanium Dioxide pigment manufactured on the basis of advanced technology. It is actively treated with unique surface dispersion technology by adding inorganic additives which can reduce the surface force between the particles of titanium dioxide, enhance the powder dry flow ability, greatly improve the dispersion properties. PA101 is a high cost effective product aiming at the demand of market with good dispersion, good whiteness, high hiding and tinting strength, low oil absorption.

Yes, it is edible and has been approved as a safe ingredient by the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), as well as the Joint FAO/WHO Expert Committee on Food Additives (JECFA).

FDA
Titanium dioxide may be safely used for coloring foods with the maximum use levels not exceeding 1% of the food. (11)

TiO2-coated mica-based pearlescent pigments can also be used as a colour additive in food. (12)

EFSA
Titanium dioxide (E171) is listed in Commission Regulation (EU) No 231/2012 as an authorised food additive in both anatase and rutile grades and categorized in “colours” with the maximum usage “quantum satis” (13).

Safety Re-evaluation in 2016
The absorption of oral dose of TiO2 is extremely low and the vast majority of it is eliminated unchanged in the faeces and only a small amount (maximum of 0.1%) is absorbed by the gut and distributed to various organs.

After the studies on genotoxicity and carcinogenicity and other researches, EFSA concluded that it is safe to use TiO2 as a food additive. EFSA also noticed that its non-food grade (nano titanium dioxide) may cause possible adverse effects in the reproductive system of mice and rats. (14)

Evaluation of New Studies of Toxicity in 2018
EFSA concluded that four studies which claimed TiO2 could cause the the health risk of carcinogenicity, genotoxicity and other problems are not solid proof or it was the nanomaterial which was dangerous instead of its food grade. (15)

Approved uses

Flavoured fermented milk products, dehydrated milk
Flavoured unripened(processed) cheese, edible cheese rind, whey cheese, beverage whiteners, edible ices
Confectionery, chewing gum, decorations, coatings and fillings

L-Lysine benefits are substantial. What is L-Lysine, which sometimes thought to be misspelled to lysine? Simply put, L-Lysine is an essential amino acid. It is in fact, one of many amino acids that the body needs for constant tissue repair and for growth as well (especially for athletes and bodybuilders). L-Lysine in the body must be acquired from food and/or supplementation.
Functions & Benefits of L-Lysine:
The benefits of l-lysine are focused. Without any further adieu, here are the most significant L- Lysine benefits.
L-Lysine natural help for shingles exists. Shingles lesions are painful due to reactivation of the varicella-zoster virus. L-Lysine appears to help treat the eruption of shingles. However, there still needs to be more research conducted to definitively proclaim it a major factor. Many have used steroids an antiviral drugs as well. Herbalists say it is helpful as well.
L-Lysine benefits include reducing the severity of herpes-related cold sores. L-Lysine inhibits the herpes virus. It prevents and relieves cold sores around genital areas, which are type 2 herpes as well as helping type 1 herpes, which is not as harsh as type 2.

Yes, it is considered safer than chemical preservatives as it is natural and it is partly hydrolyzed to L-lysine (an essential amino acid) after ingested by the human body. It has the function of both preservation and nutrition fortification.

Its safety has been approved by the Japan Ministry of Health, Labour and Welfare, U.S. Food and Drug Administration in 2003 and afterward, National Health Commission of the People’s Republic of China (NHC) approved it in 2014. It is also authorized in some other countries.

Chemical synthetic preservatives (e.g. sodium benzoate, potassium sorbate) are widely used in food to extend shelf life in today’s food industry. However, the health concerns surrounding them are always coming up which makes consumers afraid of the safety of their food and seeks safe preservatives, and thus biological preservatives stand out.

FDA
In 2004, FDA had no questions regarding the conclusion of Japan manufacturer Chisso Corporation that polylysine was generally recognized as safe (GRAS) for use as an antimicrobial agent in cooked rice or sushi rice at the maximum use levels 50 mg/kg. (4)

In 2011, FDA also had no questions regarding the conclusion of the supplier Purac Biochem b.v. that polylysine was GRAS under the intended uses as an antimicrobial agent in several food categories except for meat and poultry products at levels up to 0.025%. (5)

China NHC
